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-inches 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.
