4. Technical data

Mains supply:
Power rating:
Delivery rate max.
Delivery height max.
Delivery pressure max.
Suction height max.
Delivery and intake connection:
Water temperature max.
5. Fitting the flow switch
The electrical connection between the pressure-
operated switch and the motor already exists.
Mount the flow switch on the pressure connection
of the pump and then tighten the union nut.
6. Operating instructions
Basically, we recommend the use of a prefilter and
an intake set with an intake hose, an intake strainer
and check valve in order to prevent long repriming
times and any unnecessary damage to the pump
caused by stones and hard foreign bodies.

7. Electrical connections

Connect the power cable to a 230 V 50 Hz
earthed, 10 amp fuse minimum.
The appliance is switched on and off using the
integrated ON/OFF switch.
The motor is protected against overloading or

blocking by an integrated thermostat. In the event
of overheating, the thermostat switches off the
pump automatically. The pump will start up again
automatically after it has cooled down.

8. Suction line

Screw a suction hose (min. 3/4" plastic hose with
spiral reinforcement) directly or with a threaded
nipple to the suction connection (1" IG) of the
pump (see Figure 1).
The suction hose should have a suction valve. A
non-return valve should be installed in the suction
line in case the suction valve cannot be used.
Lay the suction line so that it ascends from the
water pick-up point to the pump. Take care not to
lay the suction line above the height of the pump -
air bubbles in the suction line will obstruct and
prolong the priming operation.
Attach the suction and delivery lines so that they
do not exert any mechanical pressure on the
pump.
The suction valve should be deep enough in the
water so that the pump will not run dry when the
level of the water drops.
A leak in the suction line will cause air to get into
the line and prevent the pump from drawing in
water.
Take care to prevent foreign bodies (sand, etc.)
being drawn in to the suction line - fit a pre-filter if
necessary.
9. Pressure line connection
The delivery pipe (we recommend at least size
3/4") has to be connected directly to the flow
switch.
A 1/2" pressure hose can also be used with the
appropriate screw connections, of course, but this
will reduce the delivery rate.
