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 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 PARMAX pump's inlet port.
Provided with the toilet is a 6 ft. (1.8m) 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
hosemender and splice the white hose to the supply hose from
the discharge port of the pump.
WARNING: Flood hazard
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.
If the toilet is installed below the vessel's waterline, in order to
prevent a siphon action from filling the toilet, aproperly 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 add a vented loop in the
Waterline
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
Vented loop
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 4ft. (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" (45cm) 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 overlapping) 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.
