3.3.1 Checking the direction of rotation
Three-phase pumps only
Check the direction of rotation every time the pump is connected to
a new installation.
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. Direction of rotation, the direction of
rotation of the motor is correct. If the jerk is counter-clockwise,
interchange two phases in the mains connection.
TM034482
Direction of rotation
If the pump is connected to a pipe system, check the 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.
4. Starting up the product
DANGER
Electric shock
Death or serious personal injury
‐
Do not use the pump in swimming pools, garden
ponds or similar places if there are people in the water.
The pump may be run briefly to check the direction of ro-
tation without being submerged in the pumped liquid.
1. Before starting the pump, check that the inlet strainer is fitted to
the pump and submerged in the pumped liquid.
2. Open the isolating valve, if fitted, and check the level switch
setting.
4.1 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 outlet pipe.
During forced operation, check the liquid level regularly to avoid dry
running.
4.2 UNILIFT KP-AV
The pump starts and stops automatically depending on the liquid
level.
4.3 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 startup, the liquid level
must be at least 30 mm.
The pump can pump down to a liquid level of 15 mm.
