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 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 

(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 the best choices. If 

a longer run of tubing is required, the tubing 

should be the 

3

/

" 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 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.
