nstallation and maintenance
Installation
Locate the pump in a dry location.
• If the pump is mounted vertically, the motor must
be above the pump house
• Mark screw positions and drill pilot holes.
• Mount the pump using stainless steel screws
with the enclosed stainless steel washer. Make
sure that the plastic spacers are in their correct
position. Take care not to over compress the vi-
bration dampening rubber feet. (The screws are
too tight if the pump house is in contact with the
surface.)
• Reinforced flexible tubing is recommended.
• Use stainless steel hose clamps to secure tubing
to quick disconnect fittings and other hose barbs
in the system.
Pump configuration
The pump can be configured in three different
ways:
• With the motor to the left
• With the motor to the right
• With the motor straight up
The set-up can easily be changed by following this
procedure:
1. Unscrew the six screws holding the pump to the
steel foot
2. Set the pump with the motor facing in the de-
sired direction
3. Fasten the six screws
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 protec-
tion to prevent the motor from overheating. The
protection is automatically restored when the mo-
tor 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.
Note: Before installation with electrical con-
trol systems, check that equipment to be
used is of sufficient rated capacity to accept
amperage draw of motor. Low voltage will
cause motor to overheat.
Maintenance
The pumps valves inside the pump house should
be regularly cleared from debris to prevent reduced
performance.
This is done by unscrewing the house clamp and
opening the house. Make sure pump is discon-
nected from the power supply.

Dry running
The pump can be run dry without any harm. It will
however unnecessary reduce your battery power.
