Service Information
Before working on the valve,
turn off the water sup-
ply
and
disconnect from electrical power
.
TO RELIEVE PRESSURE
-- 3 VALVE BYPASS:
Close the inlet valve and open
a soft water faucet. Then close the outlet valve and
open the bypass valve.
-- OPTIONAL BYPASS:
Slide the bypass valve stem
to bypass position. Loosen the 3 hex head screws
(see A in drawing) toward the backside of the valve
to allow pressure water to bleed out. Catch the water
with a rag.
DISASSEMBLY
To remove a part or group of parts, refer to the valve
drawing. A common screwdriver or nut driver, Phil-
lips screwdriver and pliers are the only tools needed
to completely disassemble.
SERVICING THE VALVE
Inspect all o-rings, seals and gaskets for wear or de-
fects.
Inspect the bottom surface of the rotor and disc for
scratches, chips or wear.
NOTE: If replacement is needed, be sure to use the
current replacement part.
ASSEMBLY
Be sure all parts are in place and in the proper posi-
tion. Lubricate ALL o-rings and seals with FDA ap-
proved silicone grease. To install the rotor seal, first
place the seal into the valve groove, rounded side
down (see cross-section). Apply a light coating of sil-
icone grease to the seal’s crossing ribs. Then, care-
fully center the wear strip on the seal, and push it
downward onto the seal.
Install the nozzle and venturi seal and drain seal. As-
semble two o-rings and the wave washer onto the ro-
tor and disc. Then center the rotor and disc, in the
valve body, on the rotor seal.
Lower the cover onto the valve body and rotor shaft.
Then install the cover holding screws.
Before tight-
ening the screws, install the valve cam and gear.
Then, turn the rotor (CLOCKWISE ONLY) to SER-
VICE position.
Tighten the screws using a criss-
cross pattern. If a torque wrench is available, torque
to 30-40 inch pounds. Lubricate the gear on the mo-
tor, and the valve cam gear with Molykote grease, or
other high quality gear lubricant. Be sure to orient
the switch as shown, with the lever toward the cam.
