inlet strainer is free of silt, mud or similar materials.

Fig. 4 Pump mounted on a plate

2.2.2 Lifting the product

Lift the pump by the lifting handle. Never lift the

pump by the power cable. Tie a rope to the lifting

handle instead.

Fig. 5 Lifting the pump

2.2.3 Positioning the product

The pump can be placed in three positions: vertical,

tilted or horizontal. The outlet port must always be

the highest point of the pump. During operation, the

inlet strainer must be covered by the pumped liquid

to ensure efficient cooling.

Fig. 6 Pump positions

2.2.4 Connecting the outlet pipe

The outlet pipe can be connected to the pump outlet

port on the top or the side by means of an adapter.

Use the 90 ° adaptor for the side outlet port.

Fig. 7 Connecting the outlet pipe

The adapter enables connection of a pipe or hose

matching 3/4", 1" and 1 1/4" external pipe thread (G).

Cut off the adapter so that it matches the outlet pipe

diameter. If a system gasket is used between the

outlet pipe and the adapter, the cut-off adapter must

have an even and smooth surface.

The approval according to DIN EN 12056-4

stipulates that the outlet pipe from the fixed

installation must be connected directly to the pump

outlet port. If the adapter supplied with the pump is to

be used, cut off the 3/4" and 1" sockets.

2.2.5 Connecting the non-return valve

To prevent backflow through the pump when it stops,

fit the non-return valve supplied in the adapter. The

non-return valve is fixed when the adapter is fitted to

the pump top outlet port.

Fig. 8 Adapter position and non-return valve

function

2.2.6 Using the side outlet port

If you want to use the side outlet port, proceed as

follows:

1. Remove the non-return valve and adapter from

the top outlet port.

2. Remove the side plug and screw it on the top

outlet port.

3. Fit the 90 ° bend adapter in the side outlet port.

Use thread sealing tape or similar material.

4. Fit the non-return valve in the vertical part of the

90 ° bend.

5. Connect the outlet line directly to the outlet port.

Fig. 9 Correct position of non-return valve

2.2.7 Adjusting the float switch cable length

To make sure that the float switch can start and stop

the pump, the free cable length must be min. 100

mm and max. 200 mm. Adjust the start and stop level

by changing the free cable length between the float

switch and the lifting handle.

• An increased free cable length results in fewer

starts and stops and a large difference in level.

• A reduced free cable length results in more starts

and stops and a small difference in level.

Fig. 10 Start and stop levels with float switch at

minimum and maximum cable lengths

Start

Stop

DANGER

Electric shock

Death or serious personal injury

- The pump must be earthed.

- The protective earth of the power outlet

must be connected to the protective

earth of the pump. The plug must

therefore have the same PE connection

system as the power outlet. If not, use a

suitable adapter.

We recommend that you fit the permanent

installation with a residual-current circuit

breaker (RCCB) with a tripping current

less than 30 mA.

DANGER

Electric shock

Death or serious personal injury

- If the pump is used for cleaning or other

maintenance of swimming pools,

garden ponds or similar places, make

sure that the pump is supplied through a

residual-current circuit breaker, RCCB,

with a rated residual operating current

of 30 mA.

WARNING

Flammable material

Death or serious personal injury

- Do not use the pump for flammable

liquids, such as diesel oil, petrol or

similar liquids.

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.

English (GB)

3.1 Venting the product

The pump is self-venting. A vent valve is built into

the lifting handle. The valve allows air to escape from

the pump in case the free air flow through the outlet

pipe is blocked. Once the pump is vented, the valve

normally closes.

If the pump sucks air or water with a high air content,

the valve may leak a mixture of air and water. This is

no fault but a natural consequence of the opening

and closing of the valve.

Fig. 12 Vent valve

3.2 Manual operation

Start and stop the pump via an external switch.

To eliminate the risk of dry running, check the water

level regularly during operation. This can for instance

be done by means of an external level controller.

In order for the pump to be able to self-prime when

started, the water level must be at least 25 mm.

When the pump sucks water, it can pump down to 20

mm water level.

3.3 Automatic operation with float switch

During automatic operation, the pump will start and

stop, depending on the water level and the float

switch position and cable length.

3.3.1 Forced operation of pump with float switch

If the pump is used to drain water below the stop

level of the float switch, the float switch can be kept

in a higher position by fixing it to the outlet pipe.

During forced operation, the water level must be

checked regularly to prevent dry running.

3.4 Pumping to low water level

The pump can pump down to 3 mm when the inlet

strainer is removed.

These conditions must be fulfilled:

• The inlet strainer must be removed.

• The pump must be placed on an even, horizontal

surface.

• The water must not contain particles which may

block the pump inlet.

• The water level must be minimum 5 mm when the

pump is started.

Fig. 13 Low water level

Removing the inlet strainer

To remove the inlet strainer, insert a screwdriver

between the pump sleeve and the inlet strainer and

turn it.

Fig. 14 Removal of inlet strainer

3.5 Thermal protection

If the pump is running without water, or if it is

otherwise overloaded, the built-in thermal switch will

cut out.

When the motor has cooled to normal temperature, it

will restart automatically.
