Step 2
– Using a 3/32 Allen Head Wrench remove both
Bluffs’ hold down screws. Remove bluffs, is there debris on
ether bluff
– remove.
Step 3
– Solenoid Valve – switch to BYPASS position.
Step 4
– Tighten the bleed off hose fitting or replace cap.
Step 5
– Supply Ball Valve – With the bluffs removed flush
the sensor bodies by partially opening the valve and
spraying with short bursts for 10 seconds to flush out the
bodies. Any contamination build-up should have been
removed.
Step 6
– Reverse above steps and activate the Unit for
proper operation.

Water doesn’t shutoff.
Once both shutoff devices are closed (no electrical power):
Step 1
- Partially open the supply ball valve. If the water
flows, then there is a problem with the solenoid valve.
Step 2
- If the water does NOT flow, shut the supply ball
valve off.
Step 3
- Partially open the return valve. If the water flows,
then there is a problem with the check valve.

Solenoid Valve Problem
Solenoid Valve will not shutoff the water:
Step 1
- Check the manual override on the valve. Confirm
that it is in the NORMAL OPERATION position.
Refer to APPENDIX Shutoff Valve Specification.
The valve could have debris blocking the balancing orifice
or the Plunger Assembly is stuck in the open position in the
Sleeve Assembly.
Step 2
- Remove the coil / Din connector assembly.
Remove the 4 screws holding the cover to the body. Turn
cover over and insert a thin wire in the balance hole
(farthest from the manual bypass knob) to ensure that the
orifice is not blocked.
Step 3
– Remove the Sleeve Assembly. The internal parts
will be the Plunger and Plunger Spring. Do they move up
and down freely? If NO then clean or replace with new
Sleeve Assembly.
Step 4
- Replace the valve cap and the coil, reassemble
and confirm that this has resolved the problem by removing
another tip.
13.
Check Valve Problem
Check Valve will not shut off the water.
Step 1
- The only way to remove the debris is to change
out the check valve with a replacement and then clean out
the check valve on the bench.
Step 2
- Remove the snap ring and push the piston out to
remove any debris.
Step 3
- Replace the new check valve with the cleaned
valve, reassemble and confirm that this has resolved the
problem by removing another tip.
