3. 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 consideration.
All components and tubing should be located in an area, which is not exposed to freezing temperatures. Do not
expose unit or tubing to direct sunlight.
3.1. 3.1. 3.1. 3.1. Goose Goose Goose Goose Faucet Faucet Faucet Faucet – – – – The faucet should be placed near the sink where drink 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 5/4”. Watch for strengthening webbing
on the underside of cast iron sinks.
3.2. 3.2. 3.2. 3.2. Pressure Pressure Pressure Pressure Tank Tank Tank Tank – – – – The pressure tank may be placed where it is convenient within 10 feet if 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 firm, level area is required.
3.3. 3.3. 3.3. 3.3. R.O. R.O. R.O. R.O. Unit Unit Unit Unit – – – – The R.O. Unit 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 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 in handy. The mounting location should allow adequate clearance and accessibility for
cartridge changes.
