in the flow direction to the receptacle. When the oil is drained (check with the dipstick of the engine)
switch off the pump immediately by moving the integrated switch to its centre position. Change the oil
receptacle to the container with new oil. Start the pump by pressing the switch in the flow direction to
the motor. Use the dipstick of the engine to make sure the right amount of oil has been filled into the
engine. Note! As soon as all oil has been drained from the engine, or when the container for refilling oil
into the engine is empty, the pump must be stopped immediately. Otherwise there is a risk of dry running
which will damage the impeller.

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 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 connected to the motor base. See the wiring table above for
correct installation. Negative wire must be black.
Choose wire size in accordance with total wire length (see table above). The wire connections must
be sealed with a marine sealant or sealed cable connectors.Other electrical devices, eg switch, circuit
breaker, must be installed between the pump and the positive (+) lead on the battery (on the red wire).
Note: Before installation with electrical control systems, check that equipment to be used is of sufficient
rated capacity to accept ampere draw of motor. Low voltage will cause motor to overheat.
