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 possible
above the water line and at
the shortest distance from the
pump. Install a 3/4"/19mm
thru-hull fitting (1250 – 1 1/8").
3. Fasten a 3/4"/ 19 mm (1250
– 28mm/ 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 lock
is important that the hose not
be allowed to dip below the
pump outlet. The hose should be
constantly rising.

Electrical installation

1. Connect the brown wire to
the positive (+) terminal of the
battery.

negative (-) terminal of the

3. Do not cut back insulation more
than necessary. Insulation or
cable sheathings have to be
removed in such a way that
they end well above the highest
bilge water level. The wire
connections should be sealed
with a marine sealant to prevent
wire corrosion.

To ensure that the power
cartridge is properly located,
twist tins in a counter
