When to change the pre-filters of any Aquasafe R.O. System.

Your system has three large vertical 10 inch canisters.  These are the pre-filter housings which hold the three different pre-filter stages.  All three pre-filters are rated for 1000 Gallons of “purified water production”. For your convenience, all filters offered by Aquasafe will fit perfectly into any Reverse Osmosis System Aquasafe has offered in the past, currently offers or will offer in the future.

Please Note: Its Important to understand the definition of “purified water production” as the ultra purified water your system will produce apposed to that of the total amount of water that will pass through your system in the course of making the ultra purified water you desire.
Once again the three pre-filters in your system are rated for 1000 gallons of “purified water production“.

How will I know when the my pre-filters reached filtering capacity?
This calculation is worked out on the average as follows:
A standard household will consume between 3-5 Gallons of purified water each day for its drinking and cooking purposes.  A 3 gallons per day consumption rate over a years time is equal to roughly 1095 Gallons and calls for a pre-filter change once annually.  A 5 Gallons per day consumption rate over a years time is equal to roughly 1825 Gallons and calls for a pre-filter change approximately once every 6 months.

Please Note: It is important to change the filters prior to their 1000 Gallon capacity being reached as if the pre-filters become entirely saturated they will not be able to perform accurately.  Also important to understand is the purpose of the pre-filters is largely to take a large portion of the work load away from the Reverse Osmosis Membrane.  If the pre-filters become entirely saturated, the Reverse Osmosis Membrane will have to work much harder to clean the water which will result in a shortening of the Reverse Osmosis Membranes Lifespan.  Adequate changing of your systems pre-filters is key to both your health and the health of your Aquasafe System.

Aquasafe highly recommends to all its customers to roughly calculate how much purified Aquasafe water your household consumes daily or weekly and then to mark your calendar accordingly to indicate when a pre-filter change is due.  A complete change of pre and post filters representing 1000 gallons of purified water production is less than $30.00; truly an amazing value!

When to change the Reverse Osmosis Membrane of any Aquasafe R.O. System.

Fourth Stage:  Reverse Osmosis Membrane (Dow Filmtech Material R.O.) 0.00001 Micron.

For your convenience, the Reverse Osmosis Membrane offered by Aquasafe will fit perfectly into any Reverse Osmosis System Aquasafe has offered in the past, currently does offer or will offer in the future.  If you need a replacement Reverse Osmosis Membrane, Please follow THIS LINK.

When should I change the reverse Osmosis Membrane?
The R.O. Membrane is the very heart of your Aquasafe Reverse Osmosis System.  The R.O. Membrane is rated for 4000-5000 Gallons of purified water production.  A new R.O Membrane will last between 3-4 years time.  Once again this calculation is worked out on the average as follows:
A Standard household will consume between 3-5 Gallons of purified water each day for its drinking and cooking purposes.  A 3 gallons per day consumption rate over a years time is equal to roughly 1095 Gallons which therefore calls for a Reverse Osmosis Membrane change once every 3.5 – 4 years.  A 5 Gallons per day consumption rate over a years time is equal to roughly 1825 Gallons which therefore calls for Reverse Osmosis change approximately once every 3- 3.5 Years.

Are you unsure when your replaced the R.O Membrane Last?
Aquasafe highly recommends you replace your Reverse Osmosis Membrane if you have never changed the Reverse Osmosis Membrane of your system and your system is more than 3 years old or if you cannot remember the last time you have replaced your Reverse Osmosis Membrane and you think it may be more than 2 or three years ago.  If you are not sure it is better to be safe than sorry.  The R.O. Membrane is the most important part of the system, therefore ensuring it is operating properly is key to properly producing the ultra purified healthy water you desire.

When to change the Post Filters of any Aquasafe R.O. System.

Post filters are defined as any filter stage after the Reverse Osmosis Membrane.  The different Post Filters stages apply differently according to the different systems Aquasafe Sales as follows:

Home II Systems & Home II System Combo Post Filter:

Stage 5:  Final Polishing filter

Maximus II System & Maximus II System Combo Post Filters:

Stage 5: DI Resin Stage
Stage 6: Final Polishing Filter

Aquarium II System & Aquarium II System Combo Post Filters:

Stage 5, 6 & 7:  DI Resin Stage:

Final Polishing Filter:

The Final Polishing filter is rated for 1800-2000 Gallons of purified water production and therefore should be changed every second time you change your three pre-filters. For your convenience, the Final Polishing Filters offered by Aquasafe will fit perfectly with any Reverse Osmosis System Aquasafe has offered in the past, currently does offer or will offer in the future.  If you need to purchase an individual Final Polishing Filter please see THIS LINK.  If you need to purchase a complete set of pre and post filters please see THIS LINK.

D.I. Resin Stage:

Maximus II System & Maximus II System Combo Post Filters:

Stage 5: DI Resin Stage
Stage 6: Final Polishing Filter

Aquarium II System & Aquarium II System Combo Post Filters:

Stage 5, 6 & 7:  DI Resin Stage:

DI Resin should be changed along with your pre-filter changes.  The DI Resin is color indicating to signify when the resin has become exhausted.  The Resin will change from Green to Amber-Orange or Brown when exhausted and needs to be changed at this point which is usually the same time the Pre-filters need to be changed.  All DI Canisters Aquasafe sales are 100% reusable by way of the removable blue end caps.  Should you need to replace the Resin Beads inside the Canister please follow THIS LINK which will direct you to the replacement Resin Beads.

It can be misleading when trying to observe the color of the resin when the canister is filled with water as the water gives a darkening effect.  To observe the true color of the resin it sis best to hold a flashlight to the canister to illuminate the true color of the resin.  Alternatively, disconnect the tubing from one side of the DI Canister and allowing a portion of water to drain from the canister will also reveal the true color of the Resin.  Before disconnecting tubing from any point on your system you should always depressurize your system.

To depressurize your system you first need to shut off the feed water supply line to your system via the Manual Shut Off Valve found spliced into the feed water line.  The “OFF” position of the manual shut off valve is horizontal to that of the tubing of the feed water line.  The feed water line should be red or orange in color and the Manual Shut Off valve will be found along the feed water line prior to the feed water line entering the first pre-filter stage of your system.  Next, turn the tank top valve found on-top of your water holding tank to its “OFF” position.  The “OFF” position of the tank top valve is horizontal to the tubing that is leading into the tank.  Now simply press down on your kitchen faucet to complete the depressurizing process.

5 Stage System

Important: Prior to removing any tubing or unscrewing any pre-filter you first need to depressurize your system which takes just seconds.  To depressurize your system you first need to shut off the feed water supply line to your system via the Manual Shut Off Valve found spliced into the feed water line.  The “OFF” position of the manual shut off valve is horizontal to that of the tubing of the feed water line.  The feed water line should be red or orange in color and the Manual Shut Off valve will be found along the feed water line prior to the feed water line entering the first pre-filter stage of your system.  Next, turn the tank top valve found on-top of your water holding tank to its “OFF” position.  The “OFF” position of the tank top valve is horizontal to the tubing that is leading into the tank.  Now simply press down on your kitchen faucet to complete the depressurizing process.  By following this easy procedure there will no water flowing during your filter change and you can begin to change your pre-filters as described below.

Changing the First pre-filter stage:  Sedimentary Filter (SED) 5 microns.
Using your Large Canister Wrench  unscrew the first of the three pre-filters.  Remove the old SED pre-filter and insert the new SED Pre-filter.  Please make sure to remove all plastic from the new SED pre-filter before inserting it into the pre-filter housing.  It does not matter which way the SED pre-filter is inserted, there is no up or down to this stage.  Making sure the SED pre-filter is centered in the pre-filter housing, tighten the pre-filter housing to the main system with reasonable force to ensure a seal using using the Large Canister Wrench.

Changing the Second pre-filter stage:  Granular Activated Carbon Filter (GAC) 1 Micron.
Repeat exactly the same process as depicted in changing the first SED pre-filter stage.  The Only Difference is that IT DOES MATER which way the GAC pre-filter is inserted into the pre-filter housing.  There is a plastic “mesh” on one end of the GAC, which is the bottom.  The top of the GAC has a rubber Gasket.

Changing the Third pre-filter stage:  Coconut Carbon Block Filter (CCB) 1 Micron.
The third pre-filter stage is the last of the pre-filters or your system.  Repeat exactly the same process as seen in changing the first pre-filter SED stage.  Just like the First Pre-filter stage, there is no up or down to this pre-filter.  Once you have finished tightening the Third pre-filter housing to the main system, you will need to conduct a “pre-filter flush”.

Flushing the pre-filters:
All water filtration stages throughout the water filtration industry should be flushed out before final use and Aquasafe’s pre-filters are no exception to this rule.  Flushing the pre-filters is very easy.
Remove the white tubing from the third pre-filter (Fig 1.1).  Next, Remove the discharge tubing (yellow tube) from the e-z flush flow restrictor (Fig 1.2) and insert that yellow tubing into the elbow of the third pre-filter housing of (Fig 1.1).  The arrow in (Fig 1.2) indicates where the yellow tubing has been removed from the E-Z flush flow restrictor.  This will complete the water path throughout the three pre-filters which will discharge into your drain pipe via the yellow discharge tubing acting to flush the three pre-filters. To initiate the pre-filter flush, simply turn on the feed water supply to your system via the Manual Shut Off Valve found along the red or orange tubing connecting to your first pre-filter.  The three pre-filters will then fill with water and begin flushing away any initial loose particulates from the manufacturing process.  Allow the water to flush through the pre-filters for 10-15 minutes.  After this time period, turn off the feed water supply and replace the yellow discharge line to its normal place (Fig. 1.2) and also reconnect the white tube into the elbow adaptor of the third pre-filter (Fig 1.1).

Fig 1.0

Fig. 1.1

Fig. 1.2

Please note:
It is not absolutely necessary for you to flush the three pre-filters.  However by flushing the pre-filters you are taking a lot of strain away from the reverse Osmosis Membrane.  If you do not conduct the pre-filter flush, the Reverse Osmosis Membrane will be forced to deal with all initial loose particulates released by the new pre-filter and therefore it is HIGHLY RECOMMENDED that you conduct a pre-filter flush when changing the pre-filters of your reverse osmosis system.

This concludes the instruction for changing the pre-filters.  Please review the additional tabs found at the top of this section for instructions on changing the Reverse Osmosis Membrane (4th stage) and the final Polishing Filter, (fifth Stage) which will conclude all filter change instructions for the Aquasafe Home II System.

For your convenience, the Reverse Osmosis Membrane offered by Aquasafe will fit perfectly into any Reverse Osmosis System Aquasafe has offered in the past, currently does offer or will offer in the future.  If you need a replacement Reverse Osmosis Membrane, Please follow THIS LINK.

Please Note: If you have not already done so, prior to working on your Aquasafe System you first need to depressurize your system which takes just seconds.  To depressurize your system you first need to shut off the feed water supply line to your system via the Manual Shut Off Valve found spliced into the feed water line.  The “OFF” position of the manual shut off valve is horizontal to that of the tubing of the feed water line.  The feed water line should be red or orange in color and the Manual Shut Off valve will be found along the feed water line prior to the feed water line entering the first pre-filter stage of your system.  Next, turn the tank top valve found on-top of your water holding tank to its “OFF” position.  The “OFF” position of the tank top valve is horizontal to the tubing that is leading into the tank.  Now simply press down on your kitchen faucet to complete the depressurizing process.  By following this easy procedure there will no water flowing during your filter change and you can begin to change your Reverse Osmosis Membrane as described below.

How to change your Reverse Osmosis Membrane:
Remove white tubing from the elbow adaptor found on the cap of the Reverse Osmosis Membrane Housing, as seen in Fig 2.0.

Fig. 2.0

Next, using the “Small Canister Wrench”, unscrew the cap of the R.O. Membrane Housing.  With the cap removed you will now be able to see the Reverse Osmosis Membrane inside the R.O. Membrane Housing.  Grab the 1 inch white cylinder protruding from the layers of the Reverse Osmosis Membrane and pull Reverse Osmosis Membrane out of the R.O. Membrane Housing.
Note: The Reverse Osmosis Membrane can swell inside the R.O. Membrane Housing making it difficult to remove by hand.  Use a pair of pliers to grab hold of the 1 inch white cylinder protruding from the layers of the Reverse Osmosis Membrane.  If you are unable to remove the Reverse Osmosis Membrane from its housing by hand, the pliers will give you the leverage you need to get the Reverse Osmosis Membrane out of the R.O. Membrane Housing.

You will now need to insert the new Reverse Osmosis Membrane into the R.O. Membrane Housing.  The new Reverse Osmosis Membrane will come sealed in a clear plastic bag for preservation purposes.  Remove the Membrane from the plastic bag and insert it firmly into the R.O. Membrane Housing firmly.

IMPORTANT,  PLEASE NOTE.
The new reverse osmosis membrane will come with a food grade preservative which saturates the Membrane so that it does not dry out.  This preservative is not harmful but none the less should be flushed from your system before you begin to consume the water produced by the new membrane.  Before consuming the water after a reverse osmosis filter change please allow your storage tank to fill and empty twice.  To empty the storage tank you simply need to open up your faucet and allow the water to drain until you have a very slow stream.  One you have emptied the storage tank for the first time, allow 1 1/2 hrs for the tank to entirely fill and then drain the tank again.  After this second draining of the storage tank your system will be producing the ultra pure drinking water you desire free to consume at your leisure.

There is a method called “flushing” the R.O. Membrane which can help to increase the life of the R.O. Membrane.  To read further on the flushing of the R.O. Membrane, please click on THIS LINK.

This concludes the instruction for changing the Reverse Osmosis Membrane of your Aquasafe Reverse Osmosis System.  Please review the additional tabs found at the top of this section for instructions on changing the final Polishing Filter, (Fifth Stage) which will conclude all filter change instructions for the Aquasafe Home II System.

Fifth Stage:  Final Polishing Filter:

This is the final filtration stage in your Aquasafe 5 stage Home II System.  The Final Polishing filter is rated for 1800-2000 Gallons of purified water production and therefore should be changed every second time you change your three pre-filters. For your convenience, the Final Polishing Filters offered by Aquasafe will fit perfectly with any Reverse Osmosis System Aquasafe has offered in the past, currently does offer or will offer in the future.

To Change this filter you will need to remove the tubing from the fittings on either side of your used final polishing filter.  There will be three different blue pieces of blue tubing you will need to remove in order to change out the Final Polishing Filter.

To remove the tubing Please reference Fig 3.0 below.

Fig 3.0

After the old Final Polishing filter is free the blue tubing you will need to remove the Male “T” adaptor fittings from your used final polishing filter and insert them into the new replacement  final polishing filter.  There is a directional  arrow engraved into the final polishing filter which indicates the direction of flow.  The “Male T” Adaptor is to be inserted on the side of the polishing filter closest to the base of the arrow and the “straight male” adaptor is to be inserted into the side of the final polishing filter closest to the point of the directional arrow.

There are two outlets to the Male “T” adaptor. One outlet of the Male “T” adaptor connects to the blue line coming out of the Reverse Osmosis Membrane housing and other outlet connects to the tubing leading to the storage tank.  It does not matter which of the two outlets of the Male “T” adaptor you choose to insert either the blue tube coming out of the reverse osmosis membrane housing or the tubing that leads to the storage tank.
The tube leading directly to the Aquasafe Kitchen Faucet dispenser connects to the “Straight Male” adaptor which once again is to be inserted on the side of the final polishing filter closest to the point of the arrow.

Please Note: If you have the text on the Final polishing filter upside down when inserted into the canister clips the blue tubing from the reverse osmosis membrane housing will more easily reach the outlet of the the Male “T” Adaptor as depicted in Fig 3.1 below.

Fig. 3.1

IMPORTANT, PLEASE NOTE:
A new Final Polishing Filter discharge a larger amount of access carbon during its first 4-6 liters of use.  Please flush out the final polishing filter by allowing 4-6 Liters to flow through it before consumption.

This concludes all filter change instructions for the Home II System.  Please check on your system every hour after the filter change for the first three to four hours inspecting for any potential small leaks.  If any drips are detected please see our “Leaks Prevention Page” via THIS LINK which will explain how to quickly and easily fix all potential leaks.

Resin Canister, (5th Stage) and the final Polishing Filter, (Sixth Stage) which will conclude all filter change instructions for the Aquasafe Maximus II System.

Fifth Stage:  D.I. Resin Canister:

In order to change the D.I. Resin of your 6oz D.I. Resin Canister, you will need to have on hand the replacement D.I. Resin beads.  If you do not have the needed replacement D.I. Resin Beads, you can easily and securely order a 24oz bag (4 refills) Via THIS LINK.

Please Note: If you have not already done so, prior to working on your Aquasafe System you first need to depressurize your system which takes just seconds.  To depressurize your system you first need to shut off the feed water supply line to your system via the Manual Shut Off Valve found spliced into the feed water line.  The “OFF” position of the manual shut off valve is horizontal to that of the tubing of the feed water line.  The feed water line should be red or orange in color and the Manual Shut Off valve will be found along the feed water line prior to the feed water line entering the first pre-filter stage of your system.  Next, turn the tank top valve found on-top of your water holding tank to its “OFF” position.  The “OFF” position of the tank top valve is horizontal to the tubing that is leading into the tank.  Now simply press down on your kitchen faucet to complete the depressurizing process.  By following this easy procedure there will no water flowing during your filter change and you can begin to change your pre-filters as described below.

Changing the D.I. Resin Beads:
To Change the D.I. Resin Beads of your D.I. Resin Canister you will first need to remove the tubing from the elbows on both sides of the canister and allow the water to drain out from it into a sink or the like by positioning the canister vertically.  Next you will need to remove one of the blue end caps.  Once the blue end cap is removed, dispose of the old D.I. Resin Beads and refill the now empty D.I. Resin canister with the new D.I. Resin Beads.  Its important to pack the D.I. Resin into the Canister tightly.  To ensure the canister is being filled properly, hold the canister vertically (straight up and down) and tap the canister lightly on a surface which will act to compact the D.I. Resin into place.  When the D.I. Resin Canister is full to the top, inspect the threads of the canister and remove any resin beads which have found their way into the threads of the canister.
Next, tighten the blue end cap back into its place.  You can now position the D.I. Resin Canister back into its normal place on the Reverse Osmosis System by pushing the canister down onto its canister clips which hold it to your reverse osmosis system.
Now all that is left to do is to reinsert the blue tubing into the elbows on both sides of the D.I. Resin Canister.

This concludes the instruction for changing the D.I Resin canister of your Aquasafe Reverse Osmosis System.  Please review the additional tabs found at the top of this section for instructions on changing the Final Polishing Filter, (6th Stage) which will conclude all filter change instructions for the Aquasafe Maximus II System.

This is the final filtration stage in your Aquasafe 5 stage Home II System.  The Final Polishing filter is rated for 1800-2000 Gallons of purified water production and therefore should be changed every second time you change your three pre-filters. For your convenience, the Final Polishing Filters offered by Aquasafe will fit perfectly with any Reverse Osmosis System Aquasafe has offered in the past, currently does offer or will offer in the future.

To Change this filter you will need to remove the tubing from the fittings on either side of your used final polishing filter.  There will be three different blue pieces of blue tubing you will need to remove in order to change out the Final Polishing Filter.

To remove the tubing Please reference Fig 3.0 below.

Fig 3.0

After the old Final Polishing filter is free the blue tubing you will need to remove the Male “T” adaptor fittings from your used final polishing filter and insert them into the new replacement  final polishing filter.  There is a directional  arrow engraved into the final polishing filter which indicates the direction of flow.  The “Male T” Adaptor is to be inserted on the side of the polishing filter closest to the base of the arrow and the “straight male” adaptor is to be inserted into the side of the final polishing filter closest to the point of the directional arrow.

There are two outlets to the Male “T” adaptor. One outlet of the Male “T” adaptor connects to the blue line coming out of the Reverse Osmosis Membrane housing and other outlet connects to the tubing leading to the storage tank.  It does not matter which of the two outlets of the Male “T” adaptor you choose to insert either the blue tube coming out of the reverse osmosis membrane housing or the tubing that leads to the storage tank.
The tube leading directly to the Aquasafe Kitchen Faucet dispenser connects to the “Straight Male” adaptor which once again is to be inserted on the side of the final polishing filter closest to the point of the arrow.

Please Note: If you have the text on the Final polishing filter upside down when inserted into the canister clips the blue tubing from the reverse osmosis membrane housing will more easily reach the outlet of the the Male “T” Adaptor as depicted in Fig 3.1 below.

Changing the First pre-filter stage:  Sedimentary Filter (SED) 5 microns.
Using your Large Canister Wrench  unscrew the first of the three pre-filters.  Remove the old SED pre-filter and insert the new SED Pre-filter.  Please make sure to remove all plastic from the new SED pre-filter before inserting it into the pre-filter housing.  It does not matter which way the SED pre-filter is inserted, there is no up or down to this stage.  Making sure the SED pre-filter is centered in the pre-filter housing, tighten the pre-filter housing to the main system with reasonable force to ensure a seal using using the Large Canister Wrench.

Changing the Second pre-filter stage:  Granular Activated Carbon Filter (GAC) 1 Micron.
Repeat exactly the same process as depicted in changing the first SED pre-filter stage.  The Only Difference is that IT DOES MATER which way the GAC pre-filter is inserted into the pre-filter housing.  There is a plastic “mesh” on one end of the GAC, which is the bottom.  The top of the GAC has a rubber Gasket.

Changing the Third pre-filter stage:  Coconut Carbon Block Filter (CCB) 1 Micron.
The third pre-filter stage is the last of the pre-filters or your system.  Repeat exactly the same process as seen in changing the first pre-filter SED stage.  Just like the First Pre-filter stage, there is no up or down to this pre-filter.  Once you have finished tightening the Third pre-filter housing to the main system, you will need to conduct a “pre-filter flush”.

Flushing the pre-filters:
All water filtration stages throughout the water filtration industry should be flushed out before final use and Aquasafe’s pre-filters are no exception to this rule.  Flushing the pre-filters is very easy.
Remove the white tubing from the third pre-filter (Fig 1.1).  See Fig 1.0 for instructions on removing tubing.  Next, Remove the discharge tubing (yellow tube) from the e-z flush flow restrictor (Fig 1.2) and insert that yellow tubing into the elbow of the third pre-filter housing of (Fig 1.1).  The arrow in (Fig 1.2) indicates where the yellow tubing has been removed from the E-Z flush flow restrictor to be inserted into the elbow of the thirst pre-filter housing.  This will complete the water path throughout the three pre-filters which will discharge into your drain pipe via the yellow discharge tubing acting to flush the three pre-filters. To initiate the pre-filter flush, simply turn on the feed water supply to your system via the Manual Shut Off Valve found along the red or orange tubing connecting to your first pre-filter.  The three pre-filters will then fill with water and begin flushing away any initial loose particulates from the manufacturing process.  Allow the water to flush through the pre-filters for 10-15 minutes.  After this time period, turn off the feed water supply and replace the yellow discharge line to its normal place (Fig. 1.2) and also reconnect the white tube into the elbow adaptor of the third pre-filter (Fig 1.1).

Please note:
It is not absolutely necessary for you to flush the three pre-filters.  However by flushing the pre-filters you are taking a lot of strain away from the reverse Osmosis Membrane.  If you do not conduct the pre-filter flush, the Reverse Osmosis Membrane will be forced to deal with all initial loose particulates released by the new pre-filter and therefore it is HIGHLY RECOMMENDED that you conduct a pre-filter flush when changing the pre-filters of your reverse osmosis system.

This concludes the instruction for changing the pre-filters.  Please review the additional tabs found at the top of this section for instructions on changing the Reverse Osmosis Membrane (4th stage), the D.I. Resin Canisters, (5th, 6th & 7th Stage) which will conclude all filter change instructions for the Aquasafe Aquarium II System.

For your convenience, the Reverse Osmosis Membrane offered by Aquasafe will fit perfectly into any Reverse Osmosis System Aquasafe has offered in the past, currently does offer or will offer in the future.  If you need a replacement Reverse Osmosis Membrane, Please follow THIS LINK.

Please Note: If you have not already done so, prior to working on your Aquasafe System you first need to depressurize your system which takes just seconds.  To depressurize your system you first need to shut off the feed water supply line to your system via the Manual Shut Off Valve found spliced into the feed water line.  The “OFF” position of the manual shut off valve is horizontal to that of the tubing of the feed water line.  The feed water line should be red or orange in color and the Manual Shut Off valve will be found along the feed water line prior to the feed water line entering the first pre-filter stage of your system.  By following this easy procedure there will no water flowing during your filter change and you can begin to change your pre-filters as described below.

How to change your Reverse Osmosis Membrane:
Remove white tubing from the elbow adaptor found on the cap of the Reverse Osmosis Membrane Housing, as seen in Fig 2.0.

Fig. 2.0

Next, using the “Small Canister Wrench”, unscrew the cap of the R.O. Membrane Housing.  With the cap removed you will now be able to see the Reverse Osmosis Membrane inside the R.O. Membrane Housing.  Grab the 1 inch white cylinder protruding from the layers of the Reverse Osmosis Membrane and pull Reverse Osmosis Membrane out of the R.O. Membrane Housing.
Note: The Reverse Osmosis Membrane can swell inside the R.O. Membrane Housing making it difficult to remove by hand.  Use a pair of pliers to grab hold of the 1 inch white cylinder protruding from the layers of the Reverse Osmosis Membrane.  If you are unable to remove the Reverse Osmosis Membrane from its housing by hand, the pliers will give you the leverage you need to get the Reverse Osmosis Membrane out of the R.O. Membrane Housing.

The new Reverse Osmosis Membrane will come sealed in a clear plastic bag for preservation purposes.  Remove the Membrane from its plastic bag.
You will now need to insert the new Reverse Osmosis Membrane into the R.O. Membrane Housing.  The end of the Reverse Osmosis Membrane that has the two small black “O” Rings is the end that is to be inserted first.  Please ensure to insert the Reverse Osmosis Membrane Firmly into place to ensure the proper seal of the Membranes “O” Rings inside the Reverse Osmosis Membrane Housing.

IMPORTANT,  PLEASE NOTE.
The new reverse osmosis membrane will come with a food grade preservative which saturates the Membrane so that it does not dry out.  This preservative is not harmful but none the less should be flushed from your system before you begin to consume the water produced by the new membrane.  Before giving water to your Aquatic pets please allow for 8-12 gallons of production water to be be generated and flushed away.

There is a method called “flushing” the R.O. Membrane which can help to increase the life of the R.O. Membrane.  To read further on the Flushing of the R.O. Membrane, please click on THIS LINK.

This concludes the instruction for changing the Reverse Osmosis Membrane of your Aquasafe Reverse Osmosis System.  Please review the remaining tab found at the top of this section for instructions on changing the D.I. Resin Canisters, (5th, 6th & 7th Stage’s) which will conclude all filter change instructions for the Aquasafe Aquarium II System.

Fifth Stage:  D.I. Resin Canister:

In order to change the D.I. Resin of your 6oz D.I. Resin Canister, you will need to have on hand the replacement D.I. Resin beads.  If you do not have the needed replacement D.I. Resin Beads, you can easily and securely order a 24oz bag (4 refills) Via THIS LINK.

Please Note: If you have not already done so, prior to working on your Aquasafe System you first need to depressurize your system which takes just seconds.  To depressurize your system you first need to shut off the feed water supply line to your system via the Manual Shut Off Valve found spliced into the feed water line.  The “OFF” position of the manual shut off valve is horizontal to that of the tubing of the feed water line.  The feed water line should be red or orange in color and the Manual Shut Off valve will be found along the feed water line prior to the feed water line entering the first pre-filter stage of your system.  By following this easy procedure there will no water flowing during your filter change and you can begin to change your pre-filters as described below.

Changing the D.I. Resin Beads:
To Change the D.I. Resin Beads of your D.I. Resin Canister you will first need to remove the tubing from the elbows on both sides of the canister and allow the water to drain out from it into a sink or the like by positioning the canister vertically.  Next you will need to remove one of the blue end caps.  Once the blue end cap is removed, dispose of the old D.I. Resin Beads and refill the now empty D.I. Resin canister with the new D.I. Resin Beads.  Its important to pack the D.I. Resin into the Canister tightly.  To ensure the canister is being filled properly, hold the canister vertically (straight up and down) and tap the canister lightly on a surface which will act to compact the D.I. Resin into place.  When the D.I. Resin Canister is full to the top, inspect the threads of the canister and remove any resin beads which have found their way into the threads of the canister.
Next, tighten the blue end cap back into its place.  You can now position the D.I. Resin Canister back into its normal place on the Reverse Osmosis System by pushing the canister down onto its canister clips which hold it to your reverse osmosis system.
Now all that is left to do is to reinsert the blue tubing into the elbows on both sides of the D.I. Resin Canister.
Repeat for Stage’s 6 & 7.

This concludes all filter change instructions for the Aquarium II System.  Please check on your system every hour after the filter change for the first three to four hours inspecting for any potential small leaks.  If any drips are detected please see our “Leaks Prevention Page” via THIS LINK which will explain how to quickly and easily fix all potential leaks.
