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. 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 cartridge.
FILTRATION DRAIN CONNECTION
A suitable drain point and air gap (check your
state and/or 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.
NOTE: See parts list on page 25 for optional
parts that may be required for a basement
installation.
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 are
done on or above the sink or countertop.
