Unauthorised Modification and Manufac-
ture of Spare Parts
Modifications or alterations of the pump are only permitted
after consultation with the manufacturer. Original spare parts
and accessories authorised by the manufacturer ensure
safety. The use of other parts can invalidate any liability of the
manufacturer for consequential damage.

Unauthorised Modes of Operation
The warranty relating to the operating reliability and safety of
the pump supplied is only valid if the machine is used in accord-
ance with its designated use as described in section 3 of the
operating manual. The limits stated in the data sheet must not
be exceeded under any circumstances.

.
-- Maximum immersion depth: 20 m (with suitable cable
length).
-- Maximum number of start-ups per hour: 30 at regular inter-
vals.
Sound pressure at minimum immersion depth:<50 dB(A).
The running noise is not audible when the pump is submerged.
Do not use the pump in ponds, tanks or swimming pools
when people may enter or come into contact with the
water.
In addition, make sure playing children cannot get near
the pump.

Pump Submerged in the Water
Fig. 2 shows an installation example in a rain water storage
reservoir.
After filling the pump with water, place it on the floor of the stor-
age reservoir. The pump takes in the medium from the area of
clean water through the floating suction hose. Make sure that
the floating suction hose can move freely up and down and al-
ways remains submerged. The suction nozzle should never be
located less than 15 cm above the floor of the reservoir, so that
the layer of deposits on the floor remains intact. The suction
nozzle’s reach can be limited by means of a float switch which
switches off the pump.
It is also possible to tie a piece of string to the floating ball to
prevent the suction strainer from sinking too low.
Make sure that the pump will not tip over during operation.
Fig. 2
A spring-loaded non-return valve or Controlmatic E must be
fitted on the discharge side to ensure that the pressure built up
by the pump will not be returned to the pump.
4.2
Pump Partially Submerged in the Water
Fig. 3 shows the pump partially submerged in the water or
sump. It draws the water from the area of clean water by means
of the floating suction hose. Care has to be taken to prevent the
pump from running dry. The suction line must remain under
water, so that it cannot take in air.
