Installation and maintenance

Installation
Locate the pump in a dry location.
If the pump is mounted vertically, the
motor shall face up.
24V
Mark screw positions and drill pilot
holes (see drilling template page 49).
Mount the pump using stainless steel
screws and with the accompanying
washers (over the rubber feet); taking
care not to over compress the vibration
dampening rubber feet.
5 A
Reinforced, high pressure flexible tubing
is recommended. If rigid pipe is used, a
length (225 mm/9 inches minimum) of
flexible tubing shall be installed between
the pump and the rigid pipe. This will
24V
address noise and/or damage caused
1 A
by vibration transmitted to rigid pipe.
Use stainless steel hose clamps to
secure tubing to quick disconnect
fittings and other hose barbs in the
system.
5 A
A strainer must be installed in line
before the pump intake, to prevent
debris from entering pump and
interfering with proper functioning of
valves.
24V
1A
Electrical installation
The pump must be installed according
to SS-EN ISO 10133 (Small craft –
Electrical system – Extra low voltage
DC installation for continuous current).
Note: The fuse must be ignition
5 A
protected.
The motor is equipped with built in
thermal protection to prevent the motor
from overheating. The protection is
24V
automatically restored when the motor
is cooled.
If the pump is connected with separate
earth lead, this should be yellow/green
and connected to the motor base.
See the wiring table for correct
installation. Negative wire must be
black.Choose wire size in accordance
8 A
with total wire lenght.
The wire connections must be sealed
with a marine sealant.
