Functional details

Please note: Lack of water
Required minimum quantity of water (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 warranty).
Never let the high-pressure pump run dry for more than 60 seconds.
Water supply
Please pay attention to the regulations of your waterworks company!
In accordance with DIN EN 61770, the high-pressure cleaner 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 item no.: 410164) 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-
pressure 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 high-pressure pump, which is normally
noticed too late or even not at all. The high-
pressure pump will be destroyed. Please
check the available quantity of water by fil-
ling a bucket with liter scale for one minute.

Insufficient quantity of electricity
Check the line fusing and have the voltage and the available current
intensity checked by an expert in case of uncertainty (see technical data).
Elektroanschluss
The high-pressure cleaner is supplied with a 5 meter length of cable fitted with
a mains plug. The plug needs to be inserted in a properly installed wall socket
equipped with a protective ground terminal and 30mA FI residual current circuit
breaker. Mains connection must be carried out by a suitably qualified electrician
and comply with IEC60364-1 requirements. The socket must be protected on the
mains side by a fuse having a time lag of at least 20 A (Type C, K). If use is made
of an extension cable this needs to be equipped with a protective conductor
properly connected up to the plug-in connections and revealing a minimum
cross-section of 2.5 mm . The plug connections must be splash-proof designs
2
and must not be allowed to lie on a wet floor.
If there are too many collectors in your
proximity connected to the network at the
same time, the available voltage and the
current intensity may decline. Consequently
the motor of the high-pressure cleaner does
not start or even blows. The power supply
may also be insufficient if the power supply
cable is too long or too thin. If extension
cables are too long, this may lead to a
voltage drop causing malfunctions or
start-up difficulties.
