6.4 Start/stop level

6.4.1 Unilift KP-A

The level difference between start and stop can be

adjusted by changing the free cable length between

the pump handle and the float switch.

• A long free cable length gives fewer starts/stops

and a large level difference.

• A short free cable length gives frequent starts/

stops and a small level difference.

To enable the float switch to start and stop the pump,

the free cable length (L) must be minimum 70 mm

and maximum 150 mm. See fig. 6.

Fig. 6 Start/stop levels, Unilift KP-A

6.4.2 Unilift KP-AV

The level difference for pumps with vertical level

switch cannot be adjusted. Start/stop levels appear

from fig. 7.

Fig. 7 Start/stop levels KP-AV

* Unilift KP 350.

6.5 Electrical connection

The electrical connection must be carried out in

accordance with local regulations and standards.

Check that the mains voltage and frequency

correspond to the values stated on the pump

nameplate.

The pump motor incorporates thermal overload

protection and requires no additional motor

protection.

If the motor is overloaded, it will stop automatically.

Motors for Unilift KP 350, 3 x 200 V, 50 Hz, must be

connected to a motor-protective circuit breaker.

Three-phase pumps with float switch (Unilift KP-A)

must be connected to the mains supply by means of

a contactor. See fig. 8.

6.5.1 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. 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 pipe system, check the

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 outlet pipe.

During forced operation, check the liquid level

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 startup, the

liquid level must be at least 30 mm.

The pump can pump down to a liquid level of 15 mm.
