THE BASIC REVERSE OSMOSIS SYSTEM 7
Rev J
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.
Optional Flush Kit: The flush kit, if used, should be placed within 6 feet of the
manifold assembly. This will minimize pressure drop and allow the flush system to
operate most efficiently.
In restricted under-sink areas, it may be easier to install the faucet first. Allow
adequate tubing lengths for final system placement.
