6.5.1 How to check the direction of rotation
(Three-phase pumps only)
Check the direction of rotation every time the pump
is connected to a new installation.
Check the direction of rotation like this:
1. Place the pump on a plane surface.
2. Start and stop the pump.
3. Observe the pump when started. If the pump
gives a slight clockwise jerk, see fig. 9, the
direction of rotation of the motor is correct. If the
jerk is counter-clockwise, interchange two phases
in the mains connection.

Fig. 9 Direction of rotation
If the pump is connected to a piping system, carry
out the check of direction of rotation in this way:
1. Start the pump and check the quantity of water.
2. Stop the pump and interchange two phases in the
mains connection.
3. Start the pump and check the quantity of water.
4. Stop the pump.
5. Compare the results taken under points 1 and 3.
The largest quantity of water indicates the correct
direction of rotation.

7. Operation

7.1 Unilift KP-A

The pump will start and stop automatically,
depending on the liquid level and the cable length of
the float switch.
Forced operation
If the pump is used for draining liquid below the stop
level of the float switch, the float switch can be held
in a higher position by fastening it to the pump
discharge pipe.
During forced operation, the liquid level should be
checked regularly to avoid dry running.

7.2 Unilift KP-AV

The pump starts and stops automatically depending
on the liquid level.

7.3 Unilift KP-M

The pump is started and stopped via an external
switch.
To avoid dry running, check the liquid level regularly
during operation, for instance via external level
monitoring.
To enable the pump to self-prime during start-up, the
liquid level must be at least 30 mm.
The pump can pump down to a liquid level of 15 mm.
