check valve in the intake line to aid primeability of flush
water pump.
10. If thru-hull seacocks cannot be conveniently operated
from toilet location, install suitable shut-off valves for
inlet and discharge connections.
** In some installations when a vented loop is installed in the
intake hose, the flushing pump primeability and flow charac-
teristics are reduced and may adversely affect toilet function.
To restore pump performance, connect a solenoid valve
(Jabsco No. 37068-0000) to the vent air inlet to interrupt the
air supply during the flush cycle. The brass port of the sole-
noid valve (remove plastic filter if attached) should be con-
nected to the vent inlet with 3/16" hose and the solenoid
wired in parallel with the toilet motor. See Diagram 1 for
installation and wiring illustration.
INSTALLATION INSTRUCTIONS
PLUMBING CONNECTIONS: Connect inlet hose using
either 5/8" or 3/4" ID hose (a sleeve is included to adapt
pump inlet from 5/8" to 3/4"). Make sure all inlet connec-
tions are airtight and free of sharp bends or restrictions.
NOTICE: The toilet inlet must not be connected to a
pressurized water system.
Connect 1" or 1-1/2" hose to discharge port (Adaptor
98023-0080 is included to convert discharge port to 1-1/2"
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"
Vented Loop Fitting must be installed in the length of hose
connecting the flushing pump to the inlet seacock. The
Vented Loop Fitting must be positioned so it remains slightly*
above the waterline at all angles of heel and trim.
*Recommended minimum height above waterline is 6".
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 inches above base of bowl.
Do not connect the toilet to the vessels
CAUTION
!
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" thick. Drill a 5/8" mounting hole and install switch
and instruction plate. Use stranded copper wire of the cor-
rect 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 cor-
roded wire connections will cause a reduction in pump per-
formance 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.
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 aromat-
ics, such as pine cleaners and strongly scented de-greas-
er 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
