Symbols on the device

Do not aim the high-pressure jet may at per-
sons, animals, live electrical equipment or
the device itself.
Protect the device against frost.
According to applicable regulations, the de-
vice must never be used with the drinking
water network without a system separator.
Ensure that the connection to your house
water system, with which the high-pressure
cleaner is operated, is equipped with a sys-
tem separator according to EN 12729 type
BA. Water that has flowed through a system
separator is classified as undrinkable. Al-
ways connect the system separator to the
water inlet and never directly to the device.
Danger of injury from electrical voltage. Only
qualified electricians or authorised and qual-
ified technical specialists are permitted to
work on the electrical systems.
Risk of burns from hot surfaces.
Health risk from poisonous exhaust gases.
Never inhale the exhaust gases.

Safety devices

CAUTION
Missing or modified safety devices
Safety devices are provided for your own protection.
Never modify or bypass safety devices.
Water shortage safeguard
The water shortage safeguard prevents the burner from
overheating in the case of water shortage. The burner
only starts up if there is sufficient water supply.
Pressure relief valve
If the high-pressure gun is closed, the overflow valve
opens and the high-pressure pump pumps the water back
to the pump suction side. That prevents the maximum per-
missible working pressure from being exceeded.
The overflow valve is set and sealed at the factory. The
adjustment is made by Customer Service.
Safety valve
The safety valve opens if the pressure relief valve is
faulty.
The safety valve is set and sealed at the factory. The ad-
justment is made by Customer Service.
Thermostat valve on the pump
The thermostat valve opens when the maximum per-
missible water temperature is exceeded and discharges
the hot water outdoors.

Pressure switch

The pressure switch switches the burner off when the
minimum working pressure is fallen short of and on
again when it is exceeded.
Emission temperature limiter
The emission temperature limiter switches the device
off when the emission temperature is too high.
The safety catch on the high-pressure gun prevents the
device from being switched on inadvertently.
