In case of leaks in the high pressure sys-
tem, the appliance is shut off.
After the operation readiness period, a so-
lenoid valve opens in the high pressure
system and relieves the pressure.
The lack of water fuse in the float container
prevents the high pressure pump from run-
ning dry in case of a lack of water.
–
This equipment produces water under
high pressure downstream to high pres-
sure cleaning devices. If required the
detergent is drawn in and added to the
water.
–
The high pressure module is perma-
nently installed in a dry, frost-free room.
The temperature at the installation site
should not exceed 40 °C. The high
pressure water is distributed through a
fixed network of pipes.
Alternatively, a hand spray gun with a
high pressure hose can be connected
directly to the high pressure outlet of the
appliance.
–
The high pressure model must be in-
stalled at a wall in such a way that the
rear opening is sealed by the wall.

creased wear and tear or formation of de-
posits.
* Test volume 1litre, Settling time 30 min-

Proper use
Please do not let mineral oil contaminat-
ed waste water reach soil, water or the
sewage system. Perform engine cleaning
and bottom cleaning therefore only on
specified places with an oil trap.
