Installation and maintenance
Installation
Locate the pump in a dry location.
If the pump is mounted vertically, the
motor shall face up.
Mark screw positions and drill pilot holes
(see drilling template page 45).
Mount the pump using stainless steel
screws taking care not to over compress
the vibration dampening rubber feet.
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

Use stainless steel hose clamps to secure
tubing to quick disconnect fittings and
other hose barbs in the system.
The strainer that follows the pump must
be installed in line before the pump intake,

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 ther-

mal protection to prevent the motor 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
