TRANSPORTATION AND STORAGE

The pump can be transported and stored in a vertical
or horizontal position.
— Always lift the pump by its lifting
handle – never by the motor cable
or the hose.
— Make sure that the pump cannot
roll or fall over and injure people
or damage property.
The pump is frostproof as long as it is operating or is
immersed in the liquid. If the pump is raised when
the temperature is below freezing, the impeller may
freeze.
The pump shall be run for a short period after being
raised in order to discharge all remaining water.
Before starting
— Before starting work on the pump,
make sure that the pump is
isolated from the power supply
and cannot be energized.
— Make sure that the pump cannot
roll or fall over and injure people
or damage property.
- Check that the visible parts on the pump and
installation are undamaged and in good condition.
- Check the oil level in the oil housing.
- Remove the fuses or open the circuit breaker and
check that the impeller can be rotated freely.
- Check that the monitoring equipment (if any) works.
- Check the direction of rotation. The impeller shall
rotate clockwise, as viewed from above. When
started, the pump will jerk in the opposite direction to
the direction in which the impeller rotates. See the
figure.
- Transpose two phase leads if the impeller rotates in
the wrong direction (3 ~).
In some installations the pump
surface and the surrounding liquid
may be hot. Bear in mind the risk of
burn injuries.
A frozen impeller can be thawed by allowing the pump
to stand immersed in the liquid for a short period
before it is started. Never use a naked flame to thaw
the pump.
For longer periods of storage, the pump must be
protected against moisture and heat. The impeller
should be rotated occasionally (for example every
other month) to prevent the seals from sticking
together.
After a long period of storage, the pump should be
inspected before it is taken into operation. Pay special
attention to the seals and the cable entry.
Follow the instructions under the heading "Before
starting".
