INSTALLATION INSTRUCTIONS:

Jabsco Utility Puppies can be mounted on any flat surface.
Fit the pump in a dry, well ventilated position where there
is full access for service. If installed in a vertical position
the motor must be above the pump head. Use the rubber
grommets provided to minimise vibration, do not
overtighten the mounting screws.
¾" BSP male threaded fittings should be used to connect
25mm (1" i.d.) suction and discharge hoses. Secure the
hose to the fittings with stainless steel hose clamps. Use
spiral reinforced hose (with a smooth internal bore) that
will not collapse under suction, or rigid or semi rigid
pipework systems. The pipework must be compatible with
the liquid being pumped. Pipe runs should be kept as
straight and short as possible, avoiding rising and dipping
over obstructions. Fit an inlet strainer on the inlet hose to
prevent blockage.
WARNING: All marine pumps discharging
overboard must be installed with the over-
board discharge well above both static and
heeled waterlines.

WIRING INSTRUCTIONS

Make all electrical connections in dry locations,
connections in humid environments should be sealed to
prevent corrosion. Protect the circuit with a correctly sized
fuse or circuit breaker in the positive (+) lead as close as
possible to the power source. Select the correct cable size
from the chart below. Inadequate voltage at the motor ter-
minals when the pump is running (not less than 10%
below rated voltage at full load) due to partially discharged
batteries or insufficient cable size may result in blowing
fuses, failure to start or poor pump performance.
Connect the black motor wire to the negative (-) battery
terminal. The red wire should run via a suitably rated
switch or circuit breaker to the positive (+) battery terminal.
WARNING: If the fuse fails repeatedly do not
fit a heavier fuse or bridge the fuse terminals
with silver paper or metal wire. Failure to
observe this instruction may result in a fire
hazard due to overheating of cables.
