WIRING DIAGRAM
SERVICE
The Jabsco Quiet-Flush Toilet does not require routine main-
tenance other than occasional cleaning to maintain a hygienic
sanitary condition. Clean toilet with mild non-abrasive cleaners
without strong aromatics. Cleaners having high concentrations of
aromatics such as pine scented concentrated cleaners and strongly
scented degreaser concentrates can cause the pump's seal to swell
and may contribute to a premature seal leak.
The toilet has no wearing parts that need periodic replacement
other than the shaft seal which, under normal conditions, should
provide several years of service before needing replacement. The
seal only requires replacement if signs of leakage are noticed
under theseal housing positioned between the motor and toilet
base assembly.
WARNING Flood hazard.
If toilet is plumbed to an overboard
discharge, close the discharge seacock prior
to disassembling toilet. Failure to do so can result in flooding
which can cause loss of property and life.
NOTICE: Before performing any service, turn off the electrical pow-
er to the toilet and rinse water pump. Take precaution to ensure it
is not turned on until the serviceis complete. Also, pump all water
from the toilet bowl and if connected to an overboard discharge,
close the discharge seacock. To replace the shaft seal, snap off the
white motor coverand remove the pump assembly by removing
the four screws with lock washers that secure it to the toilet base.
Carefully slide the pump assembly from the base ensuring the
macerator housing also slides out of the base with the pump. The
pump chopper will engage the macerator housing and it may be
necessary to gently tap the chopper against the macerator housing
to free it from the base.
Prevent the motor shaft from turning by inserting a screwdriver
in the shaft slot at the rear of the motor and unscrew the nut.
Remove the chopper blade and macerator housing from the motor
shaft. Remove the O-ring from the O-ring groove around the
outer diameter of the seal housing. With an allen wrench, loosen

the centrifugal impeller set screw and slide the impeller off the
shaft. Remove the two screws that secure the seal housing to the
motor and slide the housing off the motor shaft. Remove the two
seal washers from under the head ofeach of the two seal housing
retainer screws. With a pair of needle nose pliers, grasp the shaft
seal and pull it from the seal housing. Clean all parts and inspect
for damage.
Lubricate the OD of the new seal with a small amount of water and
press it into the seal bore with the seal's lip facing the threaded
end of the shaft. Do not use the stainless steel star retaining wash-
er supplied with theseal. Lubricate the ID of the seal and the motor
shaft with a small amount of water resistant grease. Ensure the
slinger is properly positioned on the motor shaft next to the motor
and slide the seal housing onto the motor shaft until it is against
the motor end bell. Position a new plastic seal washer under the
head of each of the flat head seal housing retainer screws and se-
cure the seal housing to the motor. Slide the centrifugal impeller
onthe motor shaft positioning it about 1/32"(1 mm) from the seal
housing and secure it to the shaft with the set screw. Rotate the
impeller to ensure it does not rub on the seal housing.
Slide the macerator housing over the motor shaft, place the
chopper plate on the end of the shaft and screw the locking nut
onto the shaft. Tighten the nut while holding the motor shaft at the
rear of the motor. Position a new O-ring in the seal housing O-ring
groove (it may be retained in the groove with a small amount of
grease). Slide the pump assembly into the toilet base ensuring
the macerator housing is properly positioned within the base. The
cut-out in the side of the macerator housing must align with the
discharge port in the base (the macerator housing is keyed so it
will only go in when properly positioned). Ensuring the O-ring is
still properly positioned in the O-ring groove in the seal housing,
place the pump assembly against the base and secure it in place
with the four screws and lock washers. Replace the white motor
cover by snapping it down over the pump motor.
