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).

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.

Close the faucet.

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.

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.

Add one capful (2 tsp or 10ml) of 5

% bleach (any household

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

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

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.

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

Pre-installation Preparation

IMPORTANT:

Read through the entire instruction manual before

beginning installation. Abundant Flow Water is not responsible

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.
