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 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.
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
address noise and/or damage caused
by vibration transmitted to rigid pipe.
Use stainless steel hose clamps to se-
cure tubing to quick disconnect fittings
and other hose barbs in the system.
A strainer must be installed
in line be-
fore the pump intake, to prevent debris
from entering pump and interfering with
proper functioning of valves.
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 protec-
ted.
The motor is equipped with built in
thermal protection to prevent the motor
from overheating. The protection is au-
tomatically 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 instal-
lation. Negative wire must be black.
Choose wire size in accordance with
total wire lenght.
