5.4 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 swit-
ched off automatically by the thermostat if
overheating occurs and is switched on again
automatically after cooling.
6. Operation
•
Install the equipment on a solid and level
surface.
•
The first time the filter is used, venting must
be performed at the ventilation screw (10)
while the pump is being filled.
•
Fill the pump housing with water via the water
filler screw (5). Filling the intake line will acce-
lerate the priming process.
•
All the shut-off devices in the discharge line
(spray nozzle, valves etc.) must be fully ope-
ned during intake in order to permit all air to
escape from the intake line.
•
Connect the mains cable. The priming pro-
cess starts automatically. – 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).

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
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 (6).
•
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 fi lter element
•
Clean the filter element at regular intervals,
and replace it when necessary.
•
Release the filter housing (7) by turning it
counter-clockwise and remove the filter ele-
ment (8).
•
Do not use abrasive cleaning agents or petrol
to clean the filter element.
•
Clean the filter element by tapping it out on
a flat surface. In cases of stubborn dirt first
clean with soapy water, then rinse with clear
water and leave to dry in the air. Assemble in
reverse order.
