Proper use

• The equipment you have purchased is designed to pump water with a maximum temperature of 35 °C. This equipment must never be used for other liquids, especially engine fuels, cleaning agents and other chemically-based products! Installed in a shaft, the equipment provides protection from flooding. However, it can be used wherever you want to move water, e.g. in the house, in the garden, and for many other applications. The equipment must not be used to operate swimming pools!
• If you want to use the equipment in bodies of water with a natural, muddy bottom, place the equipment in a slightly elevated position, e.g. on bricks.
• The equipment is not designed for continuous operation, e.g. as a circulating pump in a pond. In this case the equipment’s anticipated life will be greatly shortened because the equipment was not designed for continuous loading.
• The equipment is to be used only for its prescribed purpose. Any other use is deemed to be a case of misuse. The user / operator and not the manufacturer will be liable for any damage or injuries of any kind caused as a result of this.
• Please note that our equipment has not been designed for use in commercial, trade or industrial applications. Our warranty will be voided if the machine is used in commercial, trade or industrial businesses or for equivalent purposes.

Technical data

Before putting the equipment into operation

Installation
The equipment can be installed either:

•  Stationary with rigid tubing or
• Stationary with a flexible hose line

Note!
When installing, never hang the equipment by the discharge line or by the power cable. The equipment must be hung up with the provided carry handle or it must rest on the bottom of the shaft. To ensure that the equipment works properly, the bottom of the shaft always must be free of sludge and other accumulations of dirt. If the water level is too low, the sludge in the shaft can quickly dry out and hinder the equipment from starting. It is necessary therefore to check the equipment regularly (carry out trial start-ups).

Connecting the discharge line
Matching connection elbows and hose connectors for connecting the discharge line are included among the items supplied. Use the connection elbow which matches the hose diameter (see Fig. 2).

To assemble, proceed as follows:

• Pull a matching sealing ring onto the threaded socket of the hose connector and screw the connector hand-tight into the connection elbow (only for hose connections approx. 19 mm (3/4”), approx. 25 mm (1”) and approx. 32 mm (1 1/4″).
• Pull a matching sealing ring onto the threaded socket of the connection angle.
•  Screw the connection angle hand-tight onto the delivery connection of the pump.
• Connect the delivery hose to the hose connector and secure the hose, e.g. with a hose clip.
  Note:
  The pump shaft should measure at least 40 x 40 x 50 cm so that the floating switch can move freely.

Mains connection
The equipment you have purchased comes with an earthing-pin plug. The equipment is designed for connection to a socket outlet with earthing contact for 230 V ~ 50 Hz. Make sure that the socket-outlet is sufficiently fused (at least 6 A) and in good working order. Insert the power plug in the socket- outlet and the equipment is ready for operation.

Important!
To rule out danger, this work must be left strictly to a specialist electrician or Customer Service.

Operation

You can put the equipment into operation after you have thoroughly read the installation and operating instructions. Pay attention to the following points:

• Make sure that the equipment is set up securely.
• Check that the discharge line is fitted correctly.
• Make sure that the electrical connection is 230 V ~ 50 Hz.
• Check that the electrical socket-outlet is in good working order.
• Make sure that no moisture or water can ever reach the power connection.
• Make sure that the equipment does not run dry.

Setting the ON/OFF switching point:
The switching differential can be infinitely adjusted by extending or shortening the floating cable.

• The floating switch must be fitted so that the switching point height: ON and the switch point height: OFF can be reached easily and with little force. Check this by placing the equipment in a container filled with water and carefully raising and lowering the floating switch with your hand. You can then see whether the equipment switches on and off.
•  Make sure that the distance between the floating switch head and the cable holder is not too small. If the distance is too small, there is no guarantee that the equipment will work correctly.
• When adjusting the floating switch, make sure that the floating switch does not touch the bottom before the equipment is switched off. Important!Risk of dry running.

Replacing the power cable

If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly trained personnel to avoid danger.

Cleaning, maintenance and ordering of spare parts

Important!

• Unplug the power plug prior to any maintenance work.
• For mobile applications, the equipment should be cleaned with clear water after every usage.
• For stationary installation, it is recommended that you check the floating switch for proper functioning every three months.
• Use a water jet to remove any lint or fibrous particles that may have become trapped in the housing.
• Remove sludge from the shaft bottom and clean the shaft walls every 3 months.
• Use clear water to remove deposits from the floating switch.

Cleaning the paddle wheel
If a lot of deposits collect in the housing, the bottom part of the equipment must be dismantled as follows:

1. Disconnect the intake cage from the housing.
2. Clean the paddle wheel with clear water. Important! Do not put down or rest the equipment on the paddle wheel!
3. Assemble in reverse order.
