Functional details

Please note - important
Lack of water
A minimum water quantity of 7.5 l/min is needed for the high pressure cleaner
to operate.
If the metered quantity of water is too small, you have to use a different
water connection, guaranteeing the necessary output.
Lack of water leads to an accelerated wear of the joints (guarantee void).
Never let the pump run dry for more than 20 seconds.
Water supply
Please pay attention to the regulations of your waterworks com-
pany! In accordance with DIN EN 61770, the machine may not
be directly connected to the public drinking water supply lines.
A brief connection however is permissible according to DVGW
(German Association for Gas and Water Affairs) if a non-return
valve with tube ventilator (Kränzle order no. 41.016 4) is built into
the water supply. Once the water has passed through the non-
return valve it is no longer considered as drinking water. Also indirect connection
to the public drinking water supply lines is permissible by way of free emission
in accordance with EN 61 770; e.g. by using a reservoir with a float valve. Direct
connection to a non-drinking water supply line is permissible.

Lack of water occurs more often than you
probably believe. The more powerful a
high-cleaner is the greater is the danger
that a lack of water occurs. If there is only
an insufficient amount of water available,
cavitation (water-gas mixture) arises
inside the pump, which is normally noticed
too late or even not at all. The pump will
be destroyed. Please check the available
quantity of water by filling a bucket with
liter scale for one minute.
