3. Description

The pumps are equipped with a sturdy alternating current motor; the sealing of the pump housing to
the motor is executed on pump side using a mechanical seal and on motor side using a radial shaft
sealing ring.
The current is connected using the 10 m long connecting cable with 230 V-50 Hz alternating current.
- The pump must be connected to a socket with earthing.
- If the power is not supplied obligatory via an earth leakage circuit breaker with
maximum measured residual current 30 mA, the pump must be connected via a separate
earth leakage circuit breaker to the socket.
- The use of the pump at swimming pools and garden ponds and within their protection zones
is only permitted if the plants located there are installed according to DIN VDE 0100/part
702. It is forbidden to take a bath in the pool during operation of the pump. Ask you profes-
sional electrician.

4. Installation and commissioning

- Before commissioning of the pump, check it for possible external damages (e.g. transport
damages), in order to prevent accidents with electrical power.
A minimum water level of 15 mm is necessary for a proper operation of the pump
(exhausts to 1 mm).
If the pump shall be used in a cavity or a shaft the shaft/cavity must have a dimension of 300 x 300 x
30 mm. The suction basket must not be blocked by sludge and/or media containing fibres.
The pumping process starts with plugging the connector in the socket.
- In order to prevent damage to the shaft sealing, the pump must not run dry.

5. Maintenance

- Disconnect the power supply before carrying out any kind of work on the pump!
Maintenance contains an inspection and a cleaning of the pump housing. By releasing the 4 sheet
metal screws (n° 1.32) on the lower side of the pump, the bottom filter (n° 4.12) may be removed from
the pump housing (n° 4.10). After cleaning, reassemble these parts in reversed order and retighten the
4 sheet metal screws.
In case of a worn running wheel (e.g. due to abrasive media) a wear of the shaft sealing

ring is also possible. The inspection of the shaft sealing ring and the motor as well as
the replacement of the electric connecting cable may be effected by authorised after-sales services or
by manufacturing factory only.
- Never carry the pump on the cable, never low it on cable into the water;
never pull it on cable out of the water.
