OPERATION
The Quiet-Flush toilet provides both quiet operation
anduser control of water levels in the toilet bowl. A single
rocker switch provides a simple flush mode by activating
both the rinse water supply and the macer-ator
discharge pump simultaneously. An additional dual
action rocker switch offers independent control of the
rinse watersupply and discharge pump separately so the
bowlwater level can be easily raised or lowered by the
user.This provides a method of minimizing water use,
whendesired, as well as a means of raising the water
level inthe bowl when appropriate for user comfort. It
alsoallows for complete evacuation of the bowl water
whileunderway in rough sea conditions.

INSTALLATION
The 37245-Series Quiet Flush Toilet is complete with a
dedicated PAR-MAX 2.9 pump to provide either sea or
lake water to rinse the toilet bowl when flushing the toilet. This pump is intended to be located remotely from
the toilet but will function best if the distance from the toilet is kept to a minimum. Because it is self-priming, it
may be located above the vessel’s waterline. It must be
installed with the Pumpgard strainer (provided with the
toilet) located somewhere in the inlet plumbing to the
pump. The toilet also includes a multi-function flush control which should be installed in a bulkhead location that
is convenient to the toilet and allows access for wiring to
run from the power source and to both the toilet discharge pump and the PAR-MAX rinse water pump.
Install the toilet seat and lid assembly on the china bowl
with the fasteners provided and position the toilet in its
desired location. When locating the toilet, ensure there is
adequate clearance above and to the rear of the bowl so
the seat and lid assembly can rotate slightly past vertical
so it will remain up when lifted. It is all right to rotate the
waste pump assembly under
clearance from possible obstructions, if desired. This
can be accomplished by removing the four white plastic
hex head caps from the nuts at the base of the china
bowl and removing the four machine screws and nuts
that secure the china bowl to the base. The base can
then be reattached to the bowl at any position in 90º increments. Once the exact position for the toilet has been
determined, mark the location of the four base attachment holes on the toilet mounting surface. Determine the
best toilet attachment method using 5/16
teners (either machine screws for through bolting or lag
screws for topside attachment) and drill the appropriate
size holes for the fasteners being used. If securing the
toilet with lag screws into a plywood underlayment below
fiberglass, be sure to drill a hole through just the fiberglass layer large enough to allow clearance for the screw
threads and shank to avoid cracking the fiberglass.

"
The Pumpgard strainer should be secured with two fasteners to a solid mounting surface with the flow arrow
pointing towards the pump. The inlet hose should be cut
and each end attached to the strainer’s ports. The hose
from the strainer’s discharge port must connect with the
PAR-MAX pump’s inlet port. Provided with the toilet is a
six foot length of smooth white aesthetically pleasing
hose
to connect to the back of the toilet bowl and be
routed out of the head area. Ideally, the PAR-MAX pump
should be located so this length of hose can be connected directly to the pump’s discharge port avoiding an
additional splice to the hose leading from the pump to
the back of the toilet bowl. If this is not practical, acquire
(19 mm) barb to barb hose mender and splice the
"
a 3/4
white hose to the supply hose from the discharge port of
the pump.
!
WARNING
Flood hazard. If toilet is installed below the
waterline, it must be installed with a properly
positioned vented loop in the discharge hose.
Failure to do so can result in flooding which
can cause loss of property and life.
If the toilet is installed below the vessel’s waterline, in
order to prevent a siphon action from filling the toilet, a
properly positioned vented loop fitting must be installed
between the PAR-MAX pump and the back of the toilet
bowl. The vented loop fitting must be secured in a location that remains at least 6-8 inches (15-20 cm) above
the waterline at all angles of heel and trim (see diagram).

The PAR-MAX pump should be mounted to a solid
mounting surface. It should be secured with four fasteners through the rubber grommets that snap into the
pump’s base. Do not over-tighten the mounting screws
and crush the grommets such that they will not absorb
vibration. The pump may be mounted in any position;
however, if mounting it to a vertical surface it should be
oriented so water dripping from a loose port connection
will not drip down on the motor. Plumbing runs should be
kept as short and straight as possible. All plumbing
should be completed with quality 3/4"(19 mm) hose that
will not collapse or kink. Route the inlet hose from a 3/4
(19 mm) through hull and seacock fitting located well
below the waterline (and well forward of any discharge
through hulls, if installed) to the pump inlet port. Ensure
the inlet hose passes through an accessible location
(preferably above the vessel’s waterline) that will allow
for the installation of the Toilet Pumpgard strainer where
it can be periodically inspected and cleaned of debris.

The toilet discharge port is sized for 1
(25 mm) hose.
"
The discharge hose should be a quality grade reinforced
hose suitable for waste applications. Route the discharge hose to the holding tank in the most direct way
with as few bends as possible. To retain some water in
the bowl, it is best to loop the discharge hose up about
8-10 inches (15-20 cm) as close to the toilet as practical
then on to the holding tank. It is best to avoid any dips or
"
low spots in the discharge plumbing that can act as
water traps and collect waste. If this occurs, waste can
solidify and cause a discharge blockage.
If the toilet is plumbed to an overboard discharge, and is
below the vessel’s waterline, the discharge plumbing
must include a properly positioned vented loop. The
vented loop fitting must be secured in a location that

remains at least 6-8 inches (15-20 cm) above the waterline at all angles of heel and trim. The maximum discharge head without a notable decrease in pump performance is four feet (1.3 M).
ELECTRICAL
The electrical wiring should be independent of all other
accessories. It should be made with marine grade copper stranded wire of the gauge specified in the electrical
specifications chart. Make all wire connections with
mechanical locking type connectors (crimp type butt
connectors and terminals). Ensure the circuit is protected by a proper sized fuse or circuit breaker determined
from the electrical specifications chart. Secure all wires
to a solid surface approximately every eighteen inches
(1/2 M) along their entire length of run.
Wire the switch panel to the PAR-MAX rinse pump and
toilet waste pump as per the following wiring diagram.
The brown lead from the control panel connects with the
waste pump orange (positive) motor lead. The yellow
lead from the control panel connects with the PAR-MAX
rinse water pump orange (positive) motor lead. The
black motor lead from each pump must be connected to
battery negative. Select a location for the switch panel
that is convenient to the toilet user and will also allow
access to run the wires from
toilet’s waste pump motor and the PAR-MAX pump as
well as from the electrical power source to the switch
panel. To install the switch panel, drill two 1-3/4"(45 mm)
diameter holes (slightly over-lapping) through the selected switch mounting surface per the attached template.
Ensure the template is oriented correctly because it is
not symmetrical. Also, drill four appropriate sized holes
for the fasteners selected to secure the switch panel to
its mounting surface.

WASTE PUMP SERVICE
The Jabsco Quiet-Flush Toilet does not require routine
maintenance 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 the
seal housing positioned between the motor and toilet
base assembly.
!
WARNING
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 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.
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.
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 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"(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.
