With the right couplings it is also possible, of
course, to use a 13 mm (1/2“) delivery hose. The
smaller delivery hose results in a lower delivery
rate.
During the priming operation, fully open any
shut-off mechanisms (spray nozzles, valves,
etc.) in the pressure line so that the air can
escape without obstruction.
6.3 Electrical connections
Connect the appliance to a 230 V ~ 50 Hz
socket-outlet with earthing contact. Minimum
fuse 10 ampere.
A built-in thermostat protects the motor from
overloading and blocking. The pump is switched
off automatically by the thermostat if
overheating occurs and is switched on again
automatically after cooling.
7. Operation
Install the equipment on a solid and level
surface.
Fill the pump housing with water via the water
filler screw (5). Filling the intake line accelerates
the intake process.
Open the discharge line.
Connect the mains cable. The intake process
starts automatically; water can be suctioned in
for up to 5 minutes (maximum suction height).
The equipment will shut down when the cut-out
pressure of 3 bar is reached.
After a loss of pressure due to water
consumption the equipment will cut in again
automatically (cut-in pressure approx. 1.5 bar).
8. Replacing the power cable
If the power cable for this equipment is damaged, it
must be replaced by the manufacturer or its after-
sales service or similarly trained personnel to avoid
danger.
9. Cleaning, maintenance and
ordering of spare parts
The equipment is almost completely maintenance
free. In order to ensure a long service life, however,
we recommend that you regularly check and care for
the product.
Important!
The equipment must be disconnected from the
power supply (pull the power plug) prior to
performing any maintenance.
9.1 Servicing
If the equipment becomes clogged, connect the
discharge line to the water line and disconnect
the suction hose. Open the water line. Switch on
the equipment several times for approx.
two seconds. This should resolve the majority of
clog-related problems.
Inside the pressure tank is an expandable water
sack and an air compartment whose maximum
pressure should lie at approx. 1.3 bar. Pumping
water into the water sack causes the sack to
expand so that the pressure in the air
compartment rises to switch-off level. If the air
pressure is too low, you should raise it. To do so,
unscrew the plastic lid from the tank and top up
the pressure to the correct level using a tyre
pump with meter at the valve.
Important: Be sure to completely empty the
water bag first using the water drain screw
(2).
Replacing the mains cable: Important:
Disconnect the equipment from the power
supply! A defective mains cable may only be
replaced by a qualified electrician.
There are no parts inside the equipment which
require additional maintenance.
9.2 Storage
If the pump is not going to be used for a long
time or has to be removed for the winter months,
rinse it out with water, empty it completely and
allow it to dry.
The equipment must be completely drained
before it is subjected to frost.
After long stoppages, make sure the rotor turns
correctly by briefly switching the pump on and
off.
