INSTALLATION INSTRUCTIONS
PLUMBING CONNECTIONS: Connect inlet hose using
either 5/8" (16mm) or 3/4" (19mm) ID hose (a sleeve is included
to adapt pump inlet from 5/8" to 3/4" (16mm to 19mm)). Make
sure all inlet connections are airtight and free of sharp bends or
restrictions.
NOTICE: The toilet inlet must not be connected to a pressurized
water system.
Connect 1" (25mm) or 1-1/2" (38mm) hose to discharge port
(Adaptor 98023-0080 is included to convert discharge port to
1-1/2" (38mm) ID hose), and make suitable connection to holding
tank or other discharge system. Avoid sharp bends or restrictions.
If the toilet is, or can be, below waterline at any normal (including
static) attitude of vessel heel and/or trim, a 3/4" (19mm) Vented
Loop Fitting must be installed in the length of hose connecting the
flushing pump to the inlet seacock. The Vented Loop Fitting with
solenoid after fitting must be positioned so it remains slightly*
above the waterline at all angles of heel and trim.
*Recommended minimum height above waterline is 8" (20cm).
For above waterline installations, a check valve may have to be
installed in the flush water intake line to ensure rapid pump
priming. To retain water in bowl, make a loop in the discharge line
about 8" (20cm) above base of bowl.
CAUTION: Do not connect the toilet to the vessels
portable water for its source of supply. To do so can
result in contamination of portable water supply.
If fresh water is preferred for flushing, provide a
separate fresh water tank to supply water to the
toilet only.
DO NOT CONNECT INLET HOSE TO A PRESSURIZED PORTION OF
THE WATER SYSTEM.
ELECTRICAL CONNECTIONS: Select a location for the
switch and instruction plate, making sure wire leads from both
the toilet and power source can be routed to the switch. Ensure
the panel where installing switch is no more than 1" (25mm)
thick. Drill a 5/8" (16mm) mounting hole and install switch and
instruction plate. Use stranded copper wire of the correct size
(determined from the electrical specifications chart) to connect
one side of the switch to the positive power source.
NOTICE: Correct wire size and secure wire connections are very
important. Undersized wire and unsecured or corroded wire con-
nections will cause a reduction in pump performance and possible
pump failure. An appropriate size fuse or equivalent circuit
breaker (determined from electrical specifications chart) must
be installed in the positive power lead within seven inches
of the power source or in the electrical power distribution
breaker /fuse panel. Connect the other side of the switch to the
orange (positive) motor lead. Connect the black (negative) motor
lead to the negative side of the battery or grounded buss bar. If

the solenoid valve is being used, connect the blue wire from the
solenoid to the same wire connection at the back of the switch as
the orange wire from the motor. Connect the black wire from the
solenoid to the battery ground or negative buss bar.
NOTICE: Correct motor polarity (orange to positive, black to
negative) is important. Reverse polarity can damage motor and
void warranty. Full voltage at the motor is required to properly
operate Jabsco Electric Toilet. The toilet must be wired in a circuit
independent of all other accessories.
OPERATING INSTRUCTIONS
Make sure inlet and outlet seacocks are all open; push switch
button to operate. Operate until bowl is completely flushed and
discharge pump has scavenged water from bottom of bowl.
The Jabsco electric marine toilet will provide years of troublefree
service if properly used. It will handle waste and toilet tissue. It will
not handle rags, sanitary napkins or hard solid objects.
Clean toilet with mild non-abrasive cleaners without strong
aromatics. Cleaners having high concentrations of aromatics, such
as pine cleaners and strongly scented de-greaser concentrates, can
cause the pump's impeller to swell and possibly bind up.
If bowl does not pump out and begins to fill, partially close inlet
valve until bowl is cleared and completely pumped out. Then
operate for a few seconds with both valves open to clear entire
toilet and discharge system. For maximum safety, when toilet
is not in use or vessel is unattended, close both the inlet and
discharge seacocks.
To drain for winter layup, close inlet valve and operate for a few
seconds until all water is pumped out.
DISASSEMBLY
Disconnect pump inlet and discharge hoses. Remove four screws,
Key No. 23, pull out complete motor, pump and macerator
assembly. Remove macerator housing from base.
Close inlet and outlet seacocks prior to
disassembling toilet. Failure to do so can
result in flooding which can cause loss of property and life.
Remove discharge port, Key No. 9, and inspect joker valve.
Unscrew chopper plate lock nut, Key No. 12, by turning counter-
clockwise, facing plate and remove chopper. Prevent shaft from
turning by inserting a screw-driver in slot of shaft protruding from
rear of motor. Loosen centrifugal impeller set screw and slide
impeller off motor shaft.
Remove four flathead screws, Keys No. 17 & 18, wearplate, Key No.
21, shaft sealing sleeve, Key No. 20, gasket, Key No. 24; then slide
pump assembly off motor shaft. Replace all worn or damaged
parts, clean remaining parts.
