MOUNTING
Jabsco 4.0 GPM washdown pumps are self-priming and
may be located above or below the water supply in a dry
location. To vertically mount these units, it is best to do so
with the motor on top. This will prevent water dripping on
motor in the event of a leak. Place pump on a solid sur-
face and secure with the four mounting screws being
careful not to compress the rubber grommets which act
as shock absorbers.
PLUMBING
IT IS RECOMMENDED THAT MARINE GRADE
REINFORCED HOSE BE USED FOR ALL PLUMBING
WITH THESE MODELS OF JABSCO PUMPS.

WIRING
In an easily accessible location, install a switch to control
electricity to the pump. The switch should have an amp
rating equal to or greater than the fuse size specified for
the pump. Turn the pump off when not used for
extended periods or when the tank is empty.
The electrical circuit should be protected with an over-
current protection device in the positive lead. See chart
for proper size. The pump circuit should not include any
other electrical loads. The open terminal on the pressure
switch is positive. Black wire from the motor is negative.
Select wire size from chart below. Use total length of wire
from the battery to pump and return. Chart allows for 3%
voltage drop. If in doubt, use next larger wire size.
If you are not familiar with applicable electrical
standards, have the unit installed by a qualified
electrician.
After installation, check the voltage at the pump motor.
Voltage should be checked when pump is operating. Full
voltage must be available at the pump motor at all times.
OPERATION
1. Open seacock (washdown or livewell applications).
2. Open hose bib and/or spray nozzle.
3. Turn on pump.
4. 32605-Series. Close spray nozzle/hose bib when
water runs free of air. Pump is now ready for automatic
demand operation.
5. For prolonged operation, pump must operate at full
open flow.
CAUTION!
Motor case will get hot.
Prolonged contact during oper-
ation may cause a burn.
