6. Operation
•
Install the equipment on a solid and level
surface.
•
Remove the ventilation screw (6).
•
Unscrew the coarse filter screw (4) using the
supplied wrench (10) and remove the coarse
filter (12) together with the non-return valve
(13) as shown in Figure 3. Now you can fill the
pump housing with water via the coarse filter
screw (4). Filling the intake line accelerates
the intake process.
•
Assemble in reverse order.
•
Open the discharge line.
•
Connect the mains cable.
•
Switch on the equipment with the power
switch – priming can take up to 5 minutes at
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 con-
sumption the equipment will cut in again auto-
matically (cut-in pressure approx. 1.5 bar).
•
After finishing the work, switch off the equip-
ment with the power switch.
7. Replacing the power cable
Danger!
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.
8. Cleaning, maintenance and
ordering of spare parts
The equipment is almost completely maintenance
free. In order to ensure a long service life, howe-
ver, we recommend that you regularly check and
care for the product.
Danger!
The equipment must be disconnected from the
power supply (pull the power plug) prior to perfor-
ming any maintenance.
8.1 Servicing
•
If the equipment becomes clogged, connect
the discharge line to the water line and dis-
connect the suction hose. Open the water
line. Switch on the equipment several times

GB
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. 1.5
bar. Pumping water into the water sack cau-
ses 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 (1).
•
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.
8.2 Cleaning the coarse fi lter insert
•
Clean the coarse filter insert at regular inter-
vals, and replace it if necessary.
•
Remove the coarse filter screw (4) and coar-
se filter (12) together with the non-return val-
ve (13) (Figure 3).
•
Disassemble the coarse filter insert as shown
in figure 3.
•
Do not use abrasive cleaning agents or petrol
to clean the coarse filter and the non-return
valve.
•
Clean the coarse filter and the non-return val-
ve by tapping them on a flat surface. In cases
of stubborn dirt, first clean with soapy water,
then rinse with clear water and air-dry.
•
Assemble in reverse order.
