PRE-OPERATING INSTRUCTIONS
5. Operation
5.1 Automatic Operation
After having connected the power cable, the pump is automatically
switched on at a definite water height (cut-in height) and switches
off as soon as the water level drops down to a definite water height
(cut-out height).
5.2 Manual Operation
In case of manual operation the Submersible Pump starts when the
power cable has been connected and the float switch has been lifted.
6. Safety Tips before Operation
• For safety reasons the Submersible Pump should always be operated
via a circuit breaker safety switch (FI switch) with rated fault current
of <30mA.
• Always check the pump (above all power cable and plug) before
each operation. A damaged pump must not be used. It is absolutely
necessary to have the pump checked by your electrician.
• Take care that the electrical connections are made within a dry area,
protected from flooding.
• Protect plug and power cable (1) from heat, oil and sharp edges.
• Check line voltage. Data indicated on the type plate must match
technical data of the main supply.
• Children under the age are not allowed to operate the pump. Keep
them away from the connected unit.
• Before use, first clear the outlet.
Observe the minimum water level (see point 9, "Technical Data").
Observe max. delivery height (see point 9, "Technical Data").
Have the professional electrician or your agent replace the damaged
cable. Please use a protective switch (it's drain current is no more
than 30mA).

OPERATING INSTRUCTIONS
7. Operating Tips
• Dry-running operation causes increased wear and is to be avoided.
Therefore, the pump must be immediately switched off when water fails
to flow.
• The pump is automatically switched off on overheating by the built-in
thermal motor protector. After having cooled down, the motor
automatically switches on again. (reasons and remedy, see Trouble
Shooting Guide, point 10)
• In order to unplug, pull the plug shell not the power cable.
• The power cable (1) must not be used for mounting or relocating the
pump for submerging or lifting/securing the pump. Fix a rope to the
carrying handle (2).
• After having pumped chlorinated swimming pool water or other liquids
leaving residues, the pump should be rinsed with clear water.
• Sand and other abrasive material in the liquid cause increased wear
and reduce the pumps output.
• Avoid running of the pump for more than 10 mins, against closed
delivery side of the pump.
• The Submersible Pumps sucks off down to a residual water height
of approx. 0.2" (5mm). This flat suction height is only reached in case
of manual operation (see point 5, "Operation"), but not in case of
automatic operation.
• The Submersible Pump is equipped with an automatic deaerating
device whose function is to remove probable air licks in the pump. If the
water level drops below the vent valve (4), some water flows penetrates
outside through the vent valve. This is not a defect of your pump, but
serves to deaerate the pump.
• If in case of manual operation the pump has sucked off completely and
water flows again after the pump operation, the pump isn't deaerated
automatically. Then, the pump has to be switched off for a short time
and then switched on again.
8. Maintenance, Care and Storage.
Submersible pumps are virtually maintenance free.
WARNING
Always unplug the pump before performing maintenance.
Repairs on electrical parts should only be done at a Service Center.
In case of contamination inside the pump, the suction base (6) can be
taken off by unscrewing the 3 Phillips recessed head screws (8).
This the turbine space can be cleaned. For safety reasons a damaged
turbine (9) can only be exchanged by the Service Center.
Too protect the pump form frost damage, store the pump in a dry place.
