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
a 3/4"(19 mm) barb to barb hose mender and splice the white
hose to the supply hose from the discharge port ofthe 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
If the toilet is installed below the vessel's waterline, in order to pre-
vent 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 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 water-line at all angles of heel and trim. The maximum
dis-charge head without a notable decrease in pump performance
is 4 feet (1.3 m).
ELECTRICAL
The electrical wiring should be independent of all other accesso-
ries. 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 18 inches (0.5m) 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
the switch panel to both the 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 toits mounting surface.
