Installation Instructions
Things to Check Before Beginning Installation
WATER SUPPLY
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 the
unit to the 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.
