Installation
Please follow the installation instructions carefully to assure maximum efficiency in your
bilge pump operation.
1. Mount the pump in the lowest point of the bilge.
2. Select a point where the bilge water is to be pumped overboard as high as pos-
sible above the water line and at the shortest distance from the pump. Install a 3/4"
thru-hull fitting (L750 UC - 1.1/8").
3. Fasten a 3/4" (L750 UC - 1.1/8") fuel resistant hose from the pump outlet to the
thru-hull fitting. Avoid sharp bends or loops. Support the hose if necessary.
Note: In order to prevent air locks it is important that the hose not be allowed to dip
below the pump outlet. The hose should be constantly rising.
To remove or replace the power cartridge
See page 18
1. Lift tab and rotate the two fins in a counter clockwise direction and lift out.
2. To reinstall, first make sure that the seal is properly located. Coat the seal with a
light film of vegetable oil or mineral oil, then align the two cams on either side of the
power cartridge with the two slots in the outer housing. Press down and twist in a
clockwise rotation. To ensure that the power cartridge is properly located, twist fins
in a counter clock-wise direction without lifting tab.
Cartridge should stay in place.

The SPX Johnson Pump panel combined with the Ultima
Switch gives you an excellent installation for your boat.
The panel switch has 3 positions: OFF, MAN (on manual),

a pilot lamp. Fuses are included. The panel is delivered in
matt black finish.
Size: 73 x 60 mm
Electrical installation with the SPX Johnson Pump panel
1. Always install according to the wiring diagram on page 16.
2. With the switch in AUTO-position, the pump will now start when the bilge water
reaches 50 mm and stops when it comes down to 20 mm. You can also run the
pump "manually". Note: When running the pump in "Manual"- position, it must not
run dry. When the pump is running, the pilot lamp will be lit.
3. The size of the fuse should be chosen according to the specifications of each pump
size.
4. Important: All electrical wiring must be clamped with the connections well above
the bilge water level. Do not remove the insulation more than necessarily. All wiring
connections should be sealed with a marine sealant to avoid oxidation.
