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 compa-
ny! 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 in-
tensity checked by an expert in case of uncertainty (see technical data).
Electrical connection
The high pressure cleaner is supplied with a 5 meters long power supply cable.
The mains plug must be fitted to a standard grounded socket with a 30 mA
residual current operated device. The socket must be protected with a 16 A fuse
on the mains side. When using an extension cable, this must have an earthed
lead which is properly connected to the socket. The conductors in the extension
cable must have a minimum cross section of 1.5 mm². Plug connections must
be of a spray-proof design, and may not be located on a wet floor. For extension
cables of more than 10 m in length, the minimum cross-section must be 2.5 mm²!
When using a cable drum, the power supply cable always must be unwound all
the way.
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 volta-
ge drop causing malfunctions or start-up
difficulties.
