Quality requirements for water:
ATTENTION
Only clean water may be used as high
pressure medium. Impurities will lead to in-
creased wear and tear or formation of de-
posits in the appliance.
If recycled water is used, the following limit
values must not be exceeded.
Safety devices serve to protect the user
and must not be rendered in operational or
their functions bypassed.
The trigger safety on the trigger gun pre-
vents accidental switch-on of the appli-
ance.
– While reducing the water supply/quanti-
ty regulation at the pump head, the
overflow valve opens and part of the
water flows back to the pump suck side.
– If the hand spray gun is closed, the
overflow valve opens and the entire wa-
ter volume will flow back to the pump
suction side.
The overflow valve is set by the manufac-
turer and sealed. Setting only by customer
service.
