the water in your system may still contain bacteria. The bacteria

still has the opportunity to grow in your system and damage your

membrane, so even if you have a UV filter it is recommended that

you use this procedure. We recommend sanitizing during a filter

change, that way the old filters can be removed and thrown away,

the system can be sanitized and new filters put in.

Sanitization Procedure:

1. Turn off the feed water supply. This is done by closing the

angle adapter ball valve. The valve is closed when the handle is

at a 90° angle to the tubing (when handle is NOT parallel to

tubing).

2. Open the faucet to allow the tank to empty. This water may be

saved if so desired. Leave the faucet open until no more water

comes out.

3. Close the faucet.

4. Pull the system out to where it can be easily worked with. If

the system was installed with enough tubing to do so, simply

pull it out to where it can be worked on. If the system does not

have enough tubing, you will need to disconnect the lines to

pull it out. (When changing the membrane, it helps to have a

towel handy, as some water may leak out.) Make note of which

tube goes where to ensure the system will be hooked up the

same way it was.

5. Remove all filters and the membrane from their housings;

leave the inline filter(s) (the post filter, as well as the DI &

pH/Mineral filter if the system has them) in place.

6. Add one capful (2 tsp or 10ml) of 5 ¼% bleach (any household

bleach, such as Clorox®, will work) to each filter housing and

the membrane housing.

7. If the system was unhooked, hook it back up now.

8. Open the feed water supply and allow water to fill the

housings. Open the tank valve and allow 5 - 10 minutes for

water to fill the tank.

9. Open the faucet to allow solution to enter lines. Close the

faucet and feed water line when water begins to come out of

the faucet.

10. Let solution stand in system for 15 minutes.

11. Open the feed water line and faucet and allow water to run

through the system, 15 - 20 minutes is recommended to

Brief Technical Summary of the Filtration Process

Water enters the filter system and passes through a series of pre-

filters. The sediment filter removes particulates such as dirt and

sediment. The GAC (granular activated carbon) removes a wide

range of chemicals (including chloramines), tastes, and odors. The

carbon block filter removes chlorine and any tastes and odors the

GAC filter might miss. The pre-filters protect the membrane and

should be changed regularly to ensure maximum performance

and membrane life. (NOTE: Some special order systems may have

different pre-filters). The water is then purified using a process

called reverse osmosis (RO). As the heart of the purification

system, the RO process uses a semi-permeable, spiral-wound

membrane to separate and remove dissolved solids, organic,

pyrogens, sub-micron colloidal particles and bacteria from the

water. Feed water is delivered under pressure at about 60 PSI

through the permeator where water permeates the minute pores

of the membrane and is delivered as purified water. Impurities in

the water are concentrated in the reject stream and flushed to

drain. The RO Membrane is capable of removing 90% to 95% of

contaminates present in the water. The optional UV filter uses

ultra violet light to destroy bacteria and viruses. The optional

inline pH/mineral filter ensures a neutral pH and adds beneficial

minerals back into the water. The optional alkaline filter increases

water alkalinity, adds additional minerals, and lowers oxygen

reduction potential (ORP). The post filter gives a final polishing to

ensure clean tasting water.

Water Purification Summary:

Stage 1: Sediment - Traps dirt, sediment, & particulates

Stage 2: GAC - Chloramines, Tastes, Chemicals, & Odors

Stage 3: Carbon Block - Chlorine, Tastes, Chemicals, & Odors

Stage 4: UV (Upgrade) - Kills bacteria, viruses, & cysts

Stage 5: RO TFC Membrane - 90-95% of contaminates

Storage: Pressurized Tank
