9.1 Connecting the Pressure Washer to the Mains
Water Supply
WARNING
Make sure the pressure washer is switched off and
disconnected from the power supply before connecting to or
disconnecting from the mains water supply.
Connecting the water filter
If the pressure washer is to be operated with sandy water or
with water from cisterns, a water filter must be connected in-
line between the water hose and the pressure washer. The
water filter filters sand and dirt out of the water and thus
protects the components of the pressure washer from
damage.
To connect the water filter:
► Unscrew the coupling (1).
► Screw the water filter (2) onto the connector (3) and
tighten by hand.
► Screw the coupling (1) onto the water filter (2) and tighten
by hand.
Connecting the Water Hose
The water hose must meet the following dimensions:
– Diameter: 0.5 in. (13 mm)
– Length: between 33 ft. and 82 ft. (10 m and 25 m)
To connect the pressure washer to the mains water supply:
► Switch off the pressure washer, @ 10.2.
► Disconnect the pressure washer from the power supply.
► Remove all sand and debris from the connections and
couplings.
► Connect the water hose to the water supply.
► Fully open the tap to flush any sand or dirt from the hose.
