2. Receiving the product

WARNING

Falling objects

Death or serious personal injury

‐Keep the product in a stable position

during unpacking.

‐Wear personal protective equipment.

2.1 Inspecting the product

Check that the product received is in accordance with

the order.

Check that the voltage and frequency of the product

match voltage and frequency of the installation site.

3. Installing the product

CAUTION

Toxic material

Minor or moderate personal injury

‐The product will be classified as conta-

minated if used for a liquid which is in-

jurious to health or toxic.

‐Wear personal protective equipment.

Installation must be carried out by special-

ly trained persons and according to local

regulations.

According to EN 60335-2-41/A2:2010, this

product with 5 m of mains cable may be

used only for indoor applications.

3.1 Location

Always have at least 3 m free cable above

liquid level. This limits the installation

depth to 7 m for pumps with 10 m cable

and to 2 m for pumps with 5 m cable.

3.1.1 Minimum space

The pit, basin or tank must be sized according to the

relation between the water flow to the pit, basin or

tank and the pump performance.

When the pump is installed in a permanent

installation with a float switch, the minimum

dimensions of the pit, basin or tank must be as shown

in the figure below. The float switch is set to the

minimum free cable length.

3.2 Mechanical installation

DANGER

Electric shock

Death or serious personal injury

‐Switch off the power supply before

starting any work on the product.

‐Make sure that the power supply can-

not be accidentally switched on.

CAUTION

Sharp element

Minor or moderate personal injury

‐Wear personal protective equipment.

‐UNILIFT AP35, AP50: Make sure that

persons cannot come into contact with

the pump impeller.

Do not install the pump hanging from the

electric cable or the outlet pipe.

3.2.1 Foundation

Place the pump on a plate or on bricks so that the

inlet strainer is free of sludge, mud or similar

materials. See the figure below.

Place the pump 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

The pump can be used in vertical or horizontal

position. The outlet must be the highest point of the

pump. See the figure below.

During operation, the inlet strainer must always be

completely covered by the pumped liquid.

TM002920

Position of the pump

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.

3.2.4 Pipe connection

For permanent installation, we recommend that you fit

a union, a non-return valve and an isolating valve in

the outlet pipe.

English (GB)

3.2.5 Adjusting the float switch cable length

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.

4. Electrical connection

DANGER

Electric shock

Death or serious personal injury

‐Switch off the power supply before you

start any work on the product.

‐Make sure that the power supply can-

not be switched on accidentally.

DANGER

Electric shock

Death or serious personal injury

‐The installation must be fitted with a re-

sidual-current device (RCD) with a trip-

ping current less than 30 mA.

DANGER

Electric shock

Death or serious personal injury

‐Make sure that the power supply plug

delivered with the product is in compli-

ance with local regulations.

‐The plug must have the same protec-

tive earth (PE) connection system as

the power outlet. If not, use a suitable

adapter if allowed by local regulations.

DANGER

Electric shock

Death or serious personal injury

‐Power cables without a plug must be

connected to a supply disconnecting

device incorporated in the fixed wiring

according to the local wiring rules.

All electrical connections must be carried

out by a qualified person in accordance

with local regulations.

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.

English (GB)

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 with

differential release. 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 pumps incorporate thermal overload

protection and require no additional motor protection.

If the motor is overloaded, it will stop auto-

matically. When the motor has cooled to

normal temperature, it restarts automati-

cally.

4.1 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. Position the pump so that you can observe the

impeller.

2. Start the pump for a short period.

3. Observe the rotation of the impeller. The correct

direction of rotation is indicated by an arrow on

the inlet strainer (clockwise when seen from the

bottom). If the impeller rotates in the wrong

direction, reverse the direction of rotation by

interchanging two of the phases to the motor.

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 or

the pressure.

2. Stop the pump and interchange two of the phases

to the motor.

3. Start the pump and check the quantity of water or

the pressure.

4. Stop the pump.

Compare the results taken under points 1 and 3. The

largest quantity of water indicates the correct

direction of rotation.

English (GB)

5. 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 rotation without being sub-

merged 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.
