DRAIN FLOW CONTROL
The flow control is required for proper operation of the
Reverse Osmosis system. See illustration below. The
flow control, located inside the push-in elbow fitting on
the drain port of the Reverse Osmosis assembly,
keeps water flowing through the membrane at the
required rate. This ensures that the system produces
the best quality product water.
Periodically check the flow control to be sure the small
hole through it is clean and unrestricted.
If the flow control requires service, review the
exploded view above. Assemble and disassemble as
shown. If the flow control remains in the manifold
when the push-in elbow fitting is removed, it will be
necessary to remove the drain port’s collet and o-ring,
as shown in the next section, to retrieve it.
ASSEMBLING COLLET AND O-RING
1. Remove the collet and o-ring from the fitting with a
small screwdriver. Do not scratch the internal walls
of the fitting port.
2. Clean collet port, lubricate with silicone-based
lubricant, and insert the o-ring seal into the bottom
of the port.
3. Push the collet inward until it locks in place.
