NOTE: Chlorine will damage a T.F.C. Membrane. The Activated Carbon Prefilters have been designed to reduce chlorine from
the incoming water. Change filters every 6 months, more often if the water contains more than 1 ppm chlorine.

SECTION III: PREPARATION
A. Major System Components
The following components comprise the R.O. Drink-
ing Water System:
1. A Reverse Osmosis assembly consisting of the
aluminum bracket, filter housings, automatic
shut-off, membrane module and an in-line
carbon filter.
2. A drinking water holding tank.
3. A faucet kit.
4. A plastic tubing kit with self-piercing saddle valve
and drain clamp.
5.
Other items necessary for installation may
include wood screws or machine screws for
mounting the R.O. assembly concrete anchors
may be required for hanging on basement wall,
additional tubing or tube connectors, and plastic
wire ties for organizing tubing.
Note: For systems equipped with Quick Connect
fittings, see page 11.
B. Tools Recommended for Installation
The following tools will cover most of the installation
sites encountered:
3/8" variable speed electric drill.
Extension work light with outlet.
Safety Glasses.
1-1/4" porcelain hole cutter kit.
1-1/4" Greenlee hole punch and 1/8" and
1/2"metal drill bits for pilot hole.
Center punch and hammer.
1-1/4" wood bit.
Assorted wood and metal drill bits including
7/32" metal drill bit.
Phillips head and flat blade screwdrivers.
1/2", 9/16" and 5/8" open end wrench.
10" Crescent wrench with jaws taped to
hold faucet.
Teflon tape.
Wide masking tape or duct tape.
Plastic tubing cutter.
Extra plastic tubing.
Low range air pressure gauge.
Bicycle hand air pump.
Small bottle of liquid chlorine bleach.
C. Determine System Location
The R.O. system can be located under a sink or in
a basement depending on space availability and
the custom
er’s preference. If a basement
installation is selected, additional tubing, hardware
and fittings may be needed and a hole will have to
be made from inside the cabinet, through the floor,
to the basement. Never install in an area of the
home where temperature is freezing as damage to
the system will result.
Considerations for an ice maker or other remote
hook up should be determined, including routing
and any additional tools, fittings, and tubing that
may be required.
