TM001549
Pump placed on a plate
3.2.2 Lifting the pump
Do not pull or lift the product by the power cable.
Lift the pump using the pump handle. Do not lift the pump by the
power cable or by the outlet pipe or hose.
If the pump is installed in a well or tank, lower and lift it by means of
a wire or chain fastened to the pump handle.
3.2.3 Positioning the pump
UNILIFT KP-A and UNILIFT KP-M can be used in vertical position
with the outlet pointing upwards. The pumps may also be used in
horizontal or tilted position with the outlet as the highest point. See
fig. How to position UNILIFT KP-A and UNILIFT KP-M.
During operation, the inlet strainer must always be completely
covered by the pumped liquid.
TM001548
How to position UNILIFT KP-A and UNILIFT KP-M
Always place Unillift KP-AV in vertical position.
When the pipe or hose has been connected, place the pump in its
operating position.
Position the pump so that the pump inlet will not be blocked or
partly blocked by sludge, mud or similar materials.
In the case of permanent installation, the pit must be cleared of
sludge, pebbles, etc. before the pump is installed.
7
English (GB)

3.2.4 Pipe connection
Fit the outlet pipe or hose in the Rp 1 1/4 outlet. Steel pipes can be
screwed directly into the pump outlet.
In a permanent installation, fit a union to the outlet pipe to facilitate
mounting and removal. If a hose is used, fit a hose union.
In a permanent installation with a level switch, fit a non-return valve
to the outlet pipe or hose.
3.2.5 Start and stop levels
UNILIFT KP-A
For pumps supplied with a float switch, the difference in level
between start and stop can be adjusted by changing the free cable
length between the float switch and the pump handle.
• An increased free cable length will result in fewer starts and
stops and a large difference in level.
• A reduced free cable length will result in more frequent starts
and stops and a small difference in level.
The stop level must be above the pump inlet to prevent the pump
from taking in air.

Depending on local regulations, a pump with minimum 10
m of mains cable must be used if the pump is used as a
portable pump for different applications.
Make sure that the product is suitable for the supply voltage and
frequency available at the installation site. Voltage and frequency
are marked on the pump nameplate.
The pump must be connected to an external main switch. If the
pump is not installed close to the switch, the switch must be of a
lockable type.
Three-phase pumps must be connected to an external motor-
protective circuit breaker. The rated current of the motor-protective
circuit breaker must correspond to the electrical data marked on the
pump nameplate.
If a level switch is connected to a three-phase pump, the motor-
protective circuit breaker must be magnetically operated.
Single-phase and three-phase pumps incorporate thermal overload
protection and require no additional motor protection. Except for
UNILIFT KP 350, 3 x 200 V, 50 Hz, which must be connected to a
motor-protective circuit breaker.
If the motor is overloaded, it will stop automatically. When
the motor has cooled to normal temperature, it restarts au-
tomatically.
Three-phase pumps with a float switch, UNILIFT KP-A, must be
connected to the mains supply by means of a contactor. See the
figure below.

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.
