6. Electrical connections
앬
Connect the power cable to a 230 V 50 Hz
earthed, 10 amp fuse minimum.
앬
The appliance is switched on and off using the
integrated ON/OFF switch.
앬
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.
7. Fitting a suction pipe
앬
Screw an intake hose (min. 3/4“ plastic hose with
spiral reinforcement) either directly or with a
threaded nipple to the pump’s intake connection
(1“ IG) (see Fig. 1).
앬
The intake hose used should have an intake
valve. If the intake valve cannot be used, a check
valve should be installed in the intake line.
앬
The intake hose should rise from the water pick-
up point to the pump. Always avoid laying the
intake line higher than the pump. Air bubbles in
the intake line delay and hinder suction.
앬
The intake and pressure lines must be attached in
such a way that they do not place the pump under
any mechanical strain.
앬
The intake valve should be so far immersed in the
water that the pump cannot run dry even if the
water level falls.
앬
If the intake line is not air-tight, the intake of air
will hinder the intake of water.
앬
Avoid drawing in foreign bodies (sand etc.).
If necessary, install a prefilter for this purpose.
8. Pressure line connection
앬
The pressure line (should be at least 3/4“) must
be connected to the pump’s pressure line
connection (1“ IG) either directly or via a threaded
nipple.
앬
A 1/2“ pressure hose can also be used with the
appropriate screw connections, of course, but this
will reduce the delivery rate.
앬
All shut-off devices (spray nozzles, valves etc.) in
the pressure line must be fully opened when
priming so that any air in the intake line can
escape.
9. Starting up
앬
Set up the pump on flat and firm ground.
앬
Attach the intake line ready for use.
앬
Plug into the mains.
앬
Fill the pump with water at the pressure
connection.
앬
All shut-off devices in the pressure line (spray
nozzles, valves etc.) must be fully opened when
priming so that any air in the intake line can
escape.
앬
Depending on the suction height and the amount
of air in the intake line, priming can take anywhere
between 30 seconds and 5 minutes. If it takes
longer than this, the pump should be refilled with
water.
앬
If the pump is removed again after use, it must
always be refilled with water whenever it is
connected up and used again.
