FLOW CONTROL AND SCREEN
The flow control is vital for proper operation of the
RO membrane cartridge. The control keeps water
flow through the membrane at the needed rate to ob-
tain the best quality product water.
Whenever servicing the RO system, check the flow
control to be sure the small hole through it is clean
and unrestricted. Also check and clean or replace the
membrane cannot discharge minerals and impuri- ties to the drain if the flow control plugs with foreign
material. If this happens, it only takes a short time for
the membrane to foul and become useless.
To clean/replace flow control and screen (FIG. 10):
1.At the drain connection, depress the collet (FIG.
11)with a finger while carefully pulling on the drain tubing to remove.
2.Remove the flow control from the end of the drain tubing. Be sure the center hole is clean.
3.Check the drain tubing to be sure it's clean. Then insert the cleaned or new flow control into the tubing.
4.With a small screwdriver carefully remove the col- let and
the drain port. Thoroughly clean or replace with a
new screen. Install pointed end down.
