Installation and maintenance
Installation
Pump may be mounted in any position
without loss of efficiency; however, it is
suggested that the pump head be down
if vertical mounting is desired. Mount
motor as close as possible to power source
to obtain full voltage.
The pump should be installed so that
the motor is protected from rain or
wash down.
When using a vac-on-switch, mount
it on the connection on the inlet side
of the pump. When using a pressure
switch, mount it on the outlet side of
the pump.
electrical installation
The pump must be installed according to
ISO 10133 (Small craft - Electrical system
- Extra low voltage DC installation for
continuous current). Note: The fuse must
be ignition protected.
The motor is equipped with built in
thermal protection to prevent the mo-
tor from overheating. The protection is
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 (next page) for
correct installation. Negative wire must
be black.
Choose wire size in accordance with total
wire lenght (see table next page).
The wire connections must be sealed with
a marine sealant.
