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
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.
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.
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 Fig. 1 below.
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.
