12 THE BASIC REVERSE OSMOSIS SYSTEM
Rev B
Feed Water Valve (Not Supplied)
The feed water valve attaches to a nearby cold water supply line. The
installer will determine the type and size of valve that will be installed.
This valve connects to the 1/2-inch natural tubing.
Flush Tank (Optional)
If the flush tank is used, the 1/4-inch blue tubing will be used to
connect to the top fitting of the RO assembly manifold. Remove the
plug and push the tubing into the fitting until it stops.
STEP 5: INSTALL RO ASSSEMBLY
The RO Assembly includes the following components: sumps (3),
support leg, prefilter, RO membrane elements (2), and postfilter. The
tubing is attached to the manifold by the elbow connectors. When
choosing a location for the system, allow enough tubing for it to be
moved for periodic servicing of the filters and membrane elements.

CAUTION: If the flush tank is not used, the 1/4-inch fitting on the
manifold must be plugged or water will leak out.
