C. Site Selection for Major System Components
The R.O. System was designed to fit under a
sink, however, because of space limitations
or other reasons, the system’s flexible design
allows for other locations. When determining the
location remember that access to a cold water
tap line, the household drain, and ease of filter
replacement are important considerations.
All components and tubing should be located in
an area not exposed to freezing temperatures. If
winter temperatures are severe, the area should
be above the minimum temperature listed in
Table B for proper performance. Do not expose
unit or tubing to direct sunlight.
1. Dispensing Faucet–
The faucet should be
placed near the sink where drinking water
is normally obtained. Convenience of use
(filling of water pitchers and glasses), and an
open area beneath the faucet under the sink
for attaching product and drain tubing are
considerations. A 2" diameter flat surface is
required above and below the installation site.
The thickness of the mounting surface should
not exceed 1¼". Watch for strengthening
webbing on the underside of cast iron sinks.
2. Drinking Water Holding Tank–
The Holding
Tank may be placed where it is convenient
within 10 feet of the faucet; under the sink or
in an adjacent cabinet are best the choices.
If a longer run of tubing is required, the
tubing should be the
3
/
8
" diameter OD size
to prevent a high pressure drop. Remember,
these tanks can weigh up to 30 pounds when
full of water; a firm, level area is required.
3. R.O. Manifold Assembly–
The manifold can
be installed on either the right or left side
of the under–sink area or a cabinet. The
right side is recommended because all the
tubing will be to the back of the cabinet and
out of the way. Installation in the basement
is also an option; one location is near the
laundry/utility sink where cold potable water
and drain access are handy. The mounting
location should allow adequate clearance
and accessibility for cartridge changes.
4. Feed Water Connection–
The Feed Water
Saddle Valve should be located as close to
the manifold assembly as possible. USE A
POTABLE COLD WATER SUPPLY ONLY.
Softened water is preferred as it will extend
the life of the R.O. Membrane.
5. Drain Connection–
The waste water must
go to drain through an anti–siphon air gap.
The air gap is provided for in the base of
the faucet. If discharging into a utility sink
or standpipe, an air gap of greater than 1"
above the flood rim must be provided.
Do NOT connect the system drain line to
the dishwasher drain or near the garbage
disposal. Backpressure from these units may
cause the air gap to overflow.
