Extension cable
Extension cables should be of a watertight con-
struc tion and comply with the below-men tioned
requirements for length and cable dimensions.
1,5 mm² max 20 m
2,5 mm² max 30 m
• Cable connections should be kept dry and off the
ground.
• Always uncoil the extension cable com plete ly to
avoid heat dam age to the cable.
Water connection
Connect the high pressure washer by means of a
water hose to the water tap (pressure of inlet wa -
ter, max. 10 bar - temperature of inlet water, max.
60°C). You may use an or di nary ½" gar den hose of
min. 10 m and max. 25 m. At tach the hose using
a quick connector. NOTE: Connection to the public
mains according to regulations.
This high pressure washer is only allowed
to be connected with the drinking water
mains, when an appropriate backfl ow
preventer has been installed, Type BA according to
EN 1717. The backfl ow preventer can be ordered
under number 106411177. The length of the hose
between the backfl ow preventer and the high pres-
sure washer must be at least 10 metres to absorb
possible pressure peaks (min diameter ½ inch).
Operation by suction (for example from a rainwater
vessel) is carried out without backfl ow preventer.
Recommended suction set: 126411387.
As soon as water has fl own through the BA valve,
this water is not considered to be drinking water any
more.
IMPORTANT! Only use water without any im pu-
ri ties. If there is a risk of running sand in the inlet
water (i.e. from your own well), a fi lter should be
mounted.
