INSTALLATION
MOUNTING
Jabsco 4.0 GPM washdown pumps are self-priming and
maybe located aboveor belowthe 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.
32605-Series –Washdown
Install the PumpgardTM strainer (provided) to the hose
from the water source (thru-hull seacock or water tank).
Connect the PumpgardTM strainer to the pump inlet port.
Connect the pump discharge to a hose with a spray
nozzle.
32605-Series –w/Rule®Dual Port (Fig. 1)
Install Rule®dual port pump to seacock. Connect hose
from dual port pump to livewell/baitwell tank. Connect
washdown hose from dual port pump to PumpgardTM
strainer, connect to pump inlet port. Connect hose from
pump outlet to pressure nozzle.
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 positivelead. 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 nowready 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.

3.
Reinstall the two wires onto the spade connectors, then install
the switch cover and screw.
Check Valve Assembly
4. Install the o-ring into the o-ring groove located on the
discharge side of the check valve chamber assembly.
5. Install the check valve chamber assembly into the
diaphragm, thus aligning the check valve chamber with the
diaphragm seal walls (push in to secureto the diaphragm).
Upper Housing Assembly
6. With the check valve chamber sub assembly installed on
the diaphragm, place the upper housing assembly onto the
pre-assembled lower housing sub assembly.
7. Align the cam with the motor "D" shaft and motor list, then
slide the cam onto the motor shaft (lube the motor shaft
with a small amount of light grease).
8. Check the discharge location (see arrow on front of port) for
correct port orientation (discharge right is the standard
position).
9. Install the six pump head screws through the upper hous-
ing, 3 screws will engage to lower housing. The other 3
screws will go through the lower housing into the front end
bell assembly aligning the three pins on the front end bell
with the 3 holes on the lower housing and tighten securely.
Motor Assembly
10. Install the pump head by following steps 6 through 9.
Pump Housing
(For numbers, refer to exploded view)
1. Disconnect power to the pump motor.
2. Remove the pressure switch cover and remove the two
wire leads from the switch spade connectors.
3. Remove the six screws from the upper housing.
4. Remove the upper housing from the check valve and
diaphragm/lower housing assemblies.
Check Valve Assembly
(To replace check valve only follow steps 1 through 6)
5. The check valve chamber and o-ring are located on the
diaphragm/lower housing assembly.
6. Remove the check valve chamber subassembly from the
diaphragm/lower housing subassembly (pull the valve
chamber from the diaphragm).
Motor Replacement
7. To replace the motor only,follow steps 1 and 2, then dis-
connect 3 screws, and pull the pump head out. Replace the
motor with washer and gasket.
REASSEMBLE
PressureSwitch Assembly
1. Install the switch diaphragm into upper housing.
2. Install the switch body over the diaphragm, align the screw
holes and install the two mounting screws.
