Installation and maintenance
Installation
• Mount 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 and the enclosed washers. Make
sure that the plastic spacers are in their
correct position. NOTE: Take care not
to fasten the vibration-damping rubber
feet too much.
• Mount the outlet anti-drainback valves
and screw the connections - Viking
Power Vacuum.
NOTE: The anti-drainback valves are
mounted with the pointed end towards
the flow direction. See the drawing.
• Reinforced flexible tubing is recom-
mended.
• Use stainless steel hose clamps to secure
tubing to connections and other hose
barbs in the system.
electrical installation
The pump must be installed according to
ISO 10133 (Small craft – Electrical system
– Extra low voltage DC installation).
NOTE: The fuse must be ignition protec-
ted.
The motor is equipped with built-in
thermal protection to prevent overheating.
The protection is automatically restored
when the motor is cooled. See the wiring
diagram for correct installation. Negative
wire must be black.
Choose wire size in accordance with total
wire length (see table). The wire connec-
tions must be sealed with a marine sealant.

NOTE: Before installation with electrical
control systems, check that equipment to
be used is of sufficient rated capacity to ac-
cept amperage draw of motor. Low voltage
can cause the motor to overheat.
Maintenance
The pump valves inside the pump house
should be regularly cleared from debris to
prevent reduced performance and poor
self priming capability. This is done by
unscrewing the house clamp and opening
the house. The outlet
anti-drainback valves are located above
the connections. (Viking Power Vacuum.)
NOTE: Make sure the pump is disconnec-
ted from the power supply.
