Installation Instructions
Things to Check Before Beginning Installation
FEED WATER
The water supply to the undercounter
Reverse Osmosis system must have the
qualities listed in the specifications (see the
Specifications Guidelines section). Municipal
water supplies most often will have these
qualities. Well water may need conditioning—
have the water tested by a water analysis
laboratory and get their recommendations
for treatment.
CAUTION:
For water with a hardness
greater than 10 grains (at 6.9 pH), the use of
a softener is recommended. Failure to install
a softener will reduce the life of the Reverse
Osmosis membrane. See the Specifications
Guidelines section for additional information
on the possible need for a softener.
DRAIN POINT
A suitable drain point and air gap (check your
local codes) are needed for reject water from
the Reverse Osmosis membrane cartridge.
BASEMENT INSTALLATION
If installing in a basement, leave enough
tubing in place during installation to be able
to move unit to floor for ease at servicing and
making filter/membrane changes. Additional
tubing and fittings required.
RO FAUCET
The RO product water faucet installs on the
sink or on the countertop next to the sink.
Often, it is installed in an existing sink spray
attachment hole or a hole may be drilled.
Space is required underneath for tubing to
and from the faucet, and for securing the
faucet in place. All faucet connections and
installation procedures are done on or above
the sink or countertop. Refer to illustration
above.
