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 page 2). 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 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 Fig. 1A 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
Electronic Faucet Installation
section.
BASEMENT INSTALLATION—
If installing in a basement, leave enough tubing in
place during installation to be able to move unit to floor for ease of servicing and making
filter/membrane changes.
