B. Tools Recommended for Installation
The following tools will cover most of the
installation sites encountered:
1. 3/8" variable speed electric drill.
2. Extension work light with outlet.
3. Safety glasses.
4. 1¼" porcelain hole cutter kit.
5. 1¼" Greenlee hole punch and 1/8" and ½"
metal drill bits for pilot hole.
6. Center punch and hammer.
7. 1¼" wood bit.
8. Concrete drill bits.
9. Assorted wood and metal drill bits including
7/32" metal drill bit.
10. Phillips head and at blade screwdrivers.
11. ½", 9/16" and 5/8" open end wrenches.
12. Teon tape.
13. Wide masking tape or duct tape.
14. Plastic tubing cutter.
15. Extra plastic tubing.
16. Low range air pressure gauge.
17. Bicycle hand air pump.
18. Small bottle of liquid chlorine bleach.
19. Graduated measuring cylinder.
20. Paper towels, wisk broom and assorted clean
up materials.
C. Site Selection for Major System Components
The R.O. System was designed to t under a sink,
however, because of space limitations or other
reasons, the system’s exible design allows for
other locations. When determining the location
remember that access to a cold water tap line, the
household drain, and ease of lter 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 minimum temperature listed in Table B,
page 4 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
(lling 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 at 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 the best 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
rm, 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 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 ood 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 overow.
