Maintenance Of The Pump - Sthor 79943 Manual De Instrucciones

The pump must be connected to the 230V/50Hz AC mains with neutral earthing and a circuit protection of a minimum rating
amounting to 6A.
Do not use the pump in swimming pools.
If the pump is installed in water reservoirs to which people or animals may have access, e.g. garden ponds, or within their protec-
tion areas, then the power supply circuit must be equipped with a residual current device whose minimum rated current must be
6A and the maximum diff erential current must not exceed 30mA.
The pump must not be functioning or be connected to the mains, when in the reservoir in which it is meant to be used are people
or animals.
The surroundings of the basket of the pump must be clean, so as to avoid any blockage of the inlet suction conduits.
During the operation the upper surface of the pump must be submerged at least 7 cm below the surface of water. If the water level
drops below this value, then the fl oat switch automatically deactivates the device.
The pump may be hanged only by the holder provided for this purpose.
The pump may remain on the bottom of the reservoir, provided it is on a fl at surface.
If the pump is being operated in a well, the minimum dimensions of the well must be (40 x 40 x 50) cm.
Before any maintenance or current service of the pump, it is required to remove the plug of the cable of the pump from the mains
socket.
The device must not be operated by children or persons whose physical, sensorial and psychological capacities are reduced, or
by persons lacking the required experience and knowledge, unless they are supervised or have been trained. Supervise children
and make sure they do not use the device as a toy.
OPERATION OF THE PUMP
Starting the pump
Assembly the pump, submerse in water reservoir. Be sure, that the body of pump is completely under the water surface. The pump
is not equipped in any power switch, it starts immediately after the connection to the power supply.

MAINTENANCE OF THE PUMP

Before carrying out any maintenance work, disconnect the pump from the electrical outlet.
The pump does not require any special maintenance. The pump housing should be cleaned with clean water. It should also
ensure that the water in the reservoir, in which the pump is to work was clean and the pump must always be situated below the
water surface.
Failure
Pump doesn't work
Water fl ows uneven stream
Increase of the pump noise during operation

Solution
Check the power supply connection
Check that the inlet slots are not clogged by dirt
Contact a special repair service
Check is the pump body submerged at least 0.5 m below the
water surface, top up if necessary the water in the reservoir
