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 insufficient amount of water available,
cavitation 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 litre scale for
half a minute
.
Required minimum quantities: see technical data
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 (no
guarantee)
Connection to 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 Affairs) if a tube ventilator with check valve
(Kränzle Order-No. 41.016 4) is built into the water supply. 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.
