ELECTRICAL CONNECTIONS
Connect black wire to negative (–) terminal of battery.
The orange wire should run to a properly sized (see
electrical specifications) overload protected switch or
circuit breaker, with a wire from switch or breaker to
positive (+) terminal of battery. Electrical circuit must be
independent of all other accessories. A reversing switch
may be used to reverse the pump (JABSCO Part
Number 18753-0652). Preferred motor rotation is clock-
wise looking at shaft end of motor. To prolong motor
life, install pump so normal motor rotation is clockwise.
Use proper wire size as determined by wire table below.
OPERATION
Flexible impeller pumps must NOT be run dry, as the
pumped liquid is the lubricant for the impeller. Observe
the outlet and shut off pump as soon as liquid stops
flowing. An automatic level switch is convenient to
control the pump in some applications.
The pump cannot run against a closed outlet such as
encountered when using a garden hose type shut-off
nozzle.
Pressure for normal operation should not exceed 20 feet
of head (8.7 psi).
Temperature of pumped liquid may be in the range of 45°
- 180°F (7° - 82°C).

* Length of run is combined length of positive and negative conductors from power source to pump and back to ground. Wire size is SAE gauge
and metric (millimetres

).
WIRING DIAGRAM
Explosion hazard. If pump is operated in an area
containing flammable vapors, motor wire leads must
be joined by insulated mechanical locking connectors.
Loose or inadequate wire connections can spark
resulting in an explosion. Property damage, injury
or death can occur.
