ENGLISH
A Caution!
Do not lift pump at the cable or discharge hose; both are not desig- ned for the tensile load by the weight of the pump.
1.Submerge pump at an angle to avoid an air cushion at the under- side, which would prevent priming. Once the pump is submerged, it can be set into an upright position.
2.Lower pump to the bottom of the fluid container. Use a strong rope, fastened to the cable eye, to lower the pump.
The pump can also be operated when suspended by a rope.
6.Operation
6.1Switching ON and OFF
After connection to the mains, the sub- mersible pump is automatically switched ON and OFF by the float switch:
xIt starts pumping when the fluid has lifted the float switch fully (12).
xThe pump switches OFF when the float switch has fallen down (13).

The cable for the float switch can be moved in the cable holder (14) to adjust the distance between the switching ON and OFF positions:
xFloat switch on a "short cable": the On and OFF positions are close together.
xFloat switch on a "long cable": the On and OFF positions are wide apart.
ACaution!
The float switch must be able
to move in such way that the pump can not run dry.

7. Care and Maintenance
ADanger!Prior to all servicing:
Switch Off.
Unplug.
Service and repair work other than described here must be left to quali- fied specialists.
7.1Periodic maintenance
For the pump to function perfectly at any time periodic maintenance is required. This also applies if the pump is used under heavy conditions, but does not run for extended periods of time (e.g. when used in well drains):
Yearly service
1.Check pump casing, cables and float switch for damage.
2.Rinse pump with clear water. Remove persistant soiling, e.g. algae desposits, with brush and dishwashing liquid.
3.To flush the inside of the pump, place it into a container filled with clear water and switch ON briefly.
Cleaning the impellers
ACaution!
The impellers of a submersible pres- sure pump are a complex component. Some technical skill is therefore required for cleaning. If you perform the cleaning yourself, when disas- sembling you must take note of the assembly sequence and position of the individual parts!
1.Remove strainer base.
2.Remove the impellers as illustrated.
3.Clean all component parts. Remove persistant soiling with brush and dishwashing liquid.
4.Reassemble pump.
7.2Pump storage
ACaution!
Frost damages the pump and
accessories, as both always contain water!
xWhen there is danger of freezing remove pump and accessories and store at a
8. Trouble Shooting
ADanger!Prior to all servicing:
Switch Off.
Unplug.
8.1Fault finding
Pump does not run:
xNo mains voltage.
Check cables, plug, outlet and mains fuse.
xMains voltage too low.
Use only extension cables with sufficient lead cross section (see "Technical Specifications").
xMotor overheated, motor protection relay tripped.
Remove cause for overheating (fluid pumped too hot? Pump blocked by foreign objects?)
After cooling off the pump will switch ON again.
xFloat switch does not switch the pump ON.
