Lack of water
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 insucient 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
.
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 dierent
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 company!
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 Aairs) 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.
