Reverse Osmosis User Guide
Location of System
The reverse osmosis system is designed for installation under a sink, usually in the kitchen or
bathroom. The RO assembly can be placed on the cabinet floor in any position that does not
apply pressure on the disconnect elbows. The RO product water faucet installs on the sink or on
the countertop next to the sink.
The RO system can also be located in a location away from the faucet. A nearby water source
and drain point are required.
Note
: Keep the lengths of tubing short. Longer lengths of tubing will decrease system
performance. A booster pump can be used on the supply line.
Note
: All plumbing should be done in accordance with state and local plumbing codes.
Some codes may require installation by a licensed plumber. Check with the local plumbing
authority prior to installation.
Warning
: 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.
Water Supply
: To provide supply water to the RO system inlet, a feed supply fitting is required
or install pipe fittings as needed. The feed water 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 RO membrane element.
Drain Point
: A suitable drain point is needed for reject water from the RO system. A floor
drain, laundry tub, standpipe, sump, etc. are all acceptable. If discharging into the utility sink
or standpipe, an air gap of greater than 1/2 inch above the flood rim must be provided. A sink
p-trap drain adapter is included to install as an optional drain point where codes permit.
Do not connect the system drain line to the dishwasher drain or near the garbage disposal. Back
pressure from these units may cause the air gap to overflow.
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 inch diameter flat
surface is required above and below the installation site. The thickness of mounting surface
should not exceed 1 1/4 inches. Avoid any strengthening webbing on the underside of the sink.
RO Manifold Assembly
: The manifold can be installed on either the right or left side of the
under-sink area or cabinet. Installation in the basement is also an option. One possible location
is near the laundry/utility sink where cold potable water and drain access are close. The location
chosen should allow adequate clearance and accessibility for membrane element changes.
In restricted under-sink areas, it may be easier to install the faucet first. Allow adequate tubing
lengths for final system placement.
