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 nonabrasive 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 the seal 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, disconnect the power
supply to the toilet and take precaution to ensure it is not recon-
nected until the service is 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 cover and
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 retaining the chopper blade. Remove
the chopper 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 of each 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 washer supplied with the seal. 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 secure the seal housing to the motor. Slide
the centrifugal impeller on the motor shaft positioning it about
1/32" (1mm) 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, position the SS
chopper blade on the end of the shaft, then place the nut on the
shaft and tighten holding the shaft slot 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 cutout 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.
