TUBING/FILTER DETAIL
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.
