sequence. Refer to the instructions in the Controller
Functions section for how to perform a manual flush
sequence.
For Horizontally-mounted Systems, connect a 1/4" tubing
to the inlet mini ball valve, direct the other end of the 1/4"
tubing to a drain or a pail, and open the inlet mini ball
valve to drain the water in the internal prefilter cavity.
3. Using the cap wrench, remove the system cap.
4. Carefully remove the O-ring from the system.
5. Clean the O-ring with a clean, soft cloth. Check for nicks,
pits, proper formation and cleanliness.
6. If nothing appears unusual, apply a very small amount
of DOW CORNING 111 silicone lubricant to the O-ring
and reinstall the O-ring. If the O-ring appears damaged,
replace the O-ring with a new O-ring.
7. Replace system cap tightly using the cap wrench.
