PAR-MAX SERVICE INSTRUCTIONS
The PAR-MAX rinse water supply pump needs no periodic
maintenance for proper performance. The only time service work
should need to be performed on the pump is if it should begin
to leak water, suddenly delivers less water than normal or should
stop pumping altogether. Should the pump begin to leak water, it
will be necessary to replace the diaphragm. If the pump delivers a
reduced rate of flow from normal or stops pumping altogether, it
will be necessary to either remove debris from the pump's flapper
valves or replace the valve cage assembly.
Notice: Before performing any service, turn off the electrical power
to the toilet and rinse water pump. Take precaution to ensure it
is not turned on until service is complete. Close the inlet fitting
seacock.
It is generally easiest to remove the pump from its installed
position so that the service can be performed on a work bench. To
do this, disconnect the electrical wires from the motor wire leads.
Push the port retainer clips back toward the pump motor and pull
the port fittings from the port sockets. Unscrew the four pump
mounting fasteners and remove the pump to a location where it
can be disassembled without losing any of the pump components.
Loosen the four 5/16" hex (slotted) machine screws in the pump
body and remove the body from the motor and wobble plate
housing (use care to not drop and lose the port retainer clips and
body retaining screws and washers). The valve cage will now be
exposed which can be easily lifted off the diaphragm. Inspect the
four outer inlet valves and central discharge valve to ensure they
seat smoothly against the valve cage. Lift the outer edges of each
valve to make certain there is no debris lodged under any valve.
If there is debris lodged under any of the valves, it will cause a
diminished flow rate or loss of flow entirely. If the valves do not
seat smoothly against the valve cage, the valve cage assembly
should be replaced.
If the pump has been leaking, the diaphragm must be replaced.
Remove the four phillips head diaphragm retainer screws
and mushroom shaped diaphragm retainer caps. Remove the
diaphragm and diaphragm housing from the motor and wobble
plate housing. Inspect the wobble plate bearing to make certain it
is not corroded and still rotates smoothly.

With the new diaphragm positioned in the diaphragm housing
(ensure the raised sealing beads face outward away from the
motor) hold it against the wobble plate with the four retaining cap
holes aligned with the wobble plate sockets. Push each diaphragm
retainer cap through the diaphragm and into the socket of the
wobble plate. Secure each retaining cap to the wobble plate with
a 1" (25mm) phillips head retainer screw. Place the motor on its
rear end bell and position the valve cage against the diaphragm
ensuring each cavities seal groove is seated on its sealing bead
molded into the diaphragm. Ensure the O-ring seal that separates
the pumps intake chamber from the discharge chamber is prop-
erly seated in the ID of the raised lip around the central discharge
valve. While holding the port retainer clips in their slide grooves
in the pump body, position the body on the diaphragm and inside
the wobble plate housing. Secure the pump body to the wobble
plate housing with the four 2-1/4" (5.7cm) machine screws and
flat washers.
Reinstall the pump to its mounting surface with four fasteners
through the rubber grommets. Ensure the sealing O-ring is
properly positioned on each port fitting and, with the retaining
clips slid back, push each port fitting into its respective socket.
Slide each port retainer clip forward until it snaps securely into its
seated position. Reconnect the orange motor lead to the positive
supply wire and the black motor lead to the negative wire.
Ensure the inlet seacock is open before restoring power to and
operating the toilet.
