Proper use

This appliance has been designed for use in private households and is not intended for commercial use. The manufacturer is not responsible for any damages that may occur on account of improper use or wrong operations.

The appliance is mainly intended for the delivery of clear water (without dissolved gases) from cisterns, wells or water butts that can be fed into irrigation systems or the service water of a house (lavatory flush, washing machine, etc.).

The appliance is not intended to be operated for recirculation in swimming pools, garden ponds and fountains.

Water that has been delivered with this appliance is no drinking water!

Approved fluids

• Water with a contamination level up to a grain size of 1.5 mm
• Washing lye

Caustic, slightly inflammable and other explosive substances such as petrol, petroleum, diluted nitrogen, greases, oils, salt water and waste water from toilets as well as sludgy water that has a slower flow capacity than water, should not be transported using the pump. The temperature of the transported fluids should not exceed 35°C. The appliance is not suitable for continuous pump operation or as a stationary installations (such as a lifting device, fountain pump).

Preparing the Appliance

Risk of injury or damage due to toppling appliance. Prior to every operation, place the appliance on a level surface and secure it against rolling away.

Illustration

Connect garden hose or lifting tube:

→ When using a garden hose, screw the connection adapter into the connection piece.
Additional sealing is not required.

→ Screw a fitting hose connection piece onto the connection adapter.

→ Attach the hose end to the hose connection piece and secure it by means of a hose clamp.
Tighten the hose clamp using a ratchet (approx. 5 Nm).

Illustration

→ Push the holder for the float switch into the handle bore until it locks in place.

Illustration

→ Adjust float switch.
The float switch can be adjusted in order to adjust the switch-on and switch-off height. Reducing the distance between the float switch and the holder results in a higher switch-on level and a lower switch-off level.
Leave sufficient space so that the float switch can move freely.

→ Attach fastening rope (not included in the scope of delivery) to the handle.

→ Lower the pump on the fastening rope into the fluid to be delivered.

→ Secure the fastening rope.

Illustration

The maximum immersion depth (h1) describes the depth of the water in which the pump can still be installed. Usually it is not necessary to lower the pump to the maximum immersion depth.

The delivery height (h2) describes the height difference between the water level and the water outlet at the end of the delivery hose. The maximum delivery height must be observed so that the pump can deliver. This must be observed over the entire pathway of the pump, as the delivery height will increase with the falling water level (due to pumping).

Operation

The fluid level must be at least 5 cm for the pump to draw independently.

→ Insert the mains plug into the socket.

Dry running damages the pump.

→ Do not leave the pump unattended during operation.

→ Alternatively use a dry run protection or an electronic pressure switch with dry run protection (see optional accessories).

Finish operation

→ Disconnect the main plug from the socket.

Cleaning

Risk of electric shock. Turn off the appliance and remove the mains plug prior to performing any care and maintenance work.

Note:
Soiling can deposit and lead to malfunctions.
Rinse the pump with clear water at regular intervals.

→ Disconnect the main plug from the socket.

→ Clean the intake grille using a suitable brush and rinse with clear water.

Illustration

→ Unscrew the connection adapter from the connection piece.

→ Remove the check valve.

→ Screw the connection adapter into the connection piece.

→ Connect the garden hose to the pipe system and the pump adapter.

→ Rinse pump with clear water.

→ Install the non-return valve.
Ensure correct positioning of the check valve. The labelling "Up" must point upwards.

Die possible feed volume is even larger:

• the lower the flow heights
• the larger the diameter of the hoses used,
• the shorter the hoses used are
• the lower the pressure loss caused by the connected accessories
