TM013597

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. See fig. Position of the pump.

During continuous operation, the motor and the pump

inlet must always be completely covered by the

pumped liquid.

During intermittent operation, the motor must always

be half submerged into the pumped liquid.

TM034191

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.

3.2.5 Installation on auto coupling

See figs A and B in the Appendix.

Pumps for permanent installation can be installed on

a stationary auto coupling and operated completely or

partially submerged in the pumped liquid.

1. Drill mounting holes for guide rail bracket on the

inside of the pit and fasten the guide rail bracket

provisionally with two screws.

2. Place the auto coupling base unit on the bottom of

the pit. Use a plumb line to establish the correct

positioning. Fasten with heavy-duty expansion

bolts. If the bottom of the pit is uneven, the auto-

coupling base unit must be supported so that it is

level when being fastened.

3. Assemble the outlet line in accordance with the

generally accepted procedures and without

exposing the line to distortion or tension.

4. Knock the guide rails on to the spigots of the

bottom part of the auto coupling. Bevel the inside

of the guide rails to facilitate installation. The

guide rails must fit tightly on the spigots. We

recommend 3/4" medium size pipes as guide

rails.

5. Adapt the length of the guide rails to fit precisely

the bracket at the top.

English (GB)

6. Unscrew the provisionally fastened guide rail

bracket, fit it on top of the guide rails and finally

fasten it firmly to the pit wall.

The guide rails must not have any axial

play as this would cause noise during

pump operation.

7. Clean out debris from the pit before lowering the

pump into the pit.

8. Fit the auto-coupling half on to the outlet of the

pump. Then slide the guide bar of this coupling

half between the guide rails and lower the pump

into the pit by means of a chain. When the pump

reaches the auto-coupling base unit, the pump will

automatically connect tightly.

9. Hang up the end of the chain on a suitable hook

at the top of the pit.

10. Adjust the length of the motor cable by coiling it

up on a relief fitting, so the cable is not damaged

during operation. Fasten the relief fitting to a

suitable bracket at the top of the pit. Make sure

that the cables are not sharply bent or pinched.

The end of the cable must not be sub-

merged, as water may penetrate

through the cable into the motor.

3.2.6 Free-standing installation

See the appendix for dimensional drawing.

For free-standing installation of the pumps, fit a 90°

elbow to the outlet. The pump can be installed with a

hose or rigid pipe and valves.

In order to facilitate service of the pump, fit a flexible

union or coupling to the outlet pipe for easy

separation.

If a hose is used, make sure that the hose does not

buckle and that the inside diameter of the hose

matches that of the outlet.

If a rigid pipe is used, the union or coupling, non-

return valve and isolating valve must be fitted in the

sequence mentioned, as seen from the pump side.

If the pump is installed in muddy conditions or on

uneven ground, we recommend that you support the

pump on bricks.

3.2.7 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.

Intermittent operation

During intermittent operation, the motor must always

be half submerged into the pumped liquid.

The pump is allowed to run for maximum 5 minutes

per 30 minutes without the motor being submerged in

the liquid.

Continuous operation

During continuous operation, the motor and the pump

inlet must always be completely covered by the

pumped liquid.

3.3 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.

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.

3.4 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 top of the motor (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.

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 rotation without being sub-

merged in the pumped liquid.

1. Before starting the pump, submerge the pump

inlet in the pumped liquid.

2. Open the isolating valve, if fitted, and check the

level switch setting.
