Other electrical devices, eg switch,
circuit breaker, must be installed
between the pump and the positive (+)
lead on the battery (on the red wire).
The pump has a in-line fuse on the
positive (red) wire. This fuse works as
over-current protection, and protects
the motor from overloading and
rotation. It is important to use the right
fuse size for replacement (see spare
parts list, page 21-22). Use fuse-links.
Incorrect fuse size may cause fire.
If the pump is connected with
separate earth lead, this should be
yellow/green and connected to the
motor base.
Choose wire size in accordance with
total wire lenght (see table below).

The wire connections must be sealed
with a marine sealant.
Note: Before installation with
electrical control systems, check that
equipment to be used is of sufficient
rated capacity to accept ampere draw
of motor. Low voltage will cause motor
to overheat.
When the pump is used as bilge pump
Max total head 0.6 m.
The pump must be installed so that
the motor is protected from splash
from bilge water.
The pump must be fitted with a
strainer or other means of preventing
debris from entering the pump.
Self-priming
Pump is self-priming up to 1.5 m.
Intake lines must be air-tight to ensure
self-priming. Note: Pump will prime
when impeller is dry but suction lift up
to 1.5 m is only obtainable when
impeller is greased or lubricated with
liquid being pumped.
For permanent installations where
suction lift exceeds 1.5 m, a foot valve
should be used to assure priming on
start up.
Continuous duty
For continuous duty 0.6 bar (60 kPa)
maximum head is permissible. The
normal working temperature of the
motor is +80°C.
Dry running
Do not run dry for more than 30
seconds. Lack of liquid will burn the
impeller and damage the seals.
