Motor protection switch
The pump motor is protected from overload by a motor protecting switch. In case of
an overload the motor is switched off by this motor protecting switch. For a restart
the master switch has to be switched off and then on again. In case of a repeated
switching off of the motor by the motor protecting switch the cause of the
malfunction has to be removed.
Replacement and inspection work may
only be performed by trained personnel.

Water system
The water flows into a tank.
A float valve (a) regulates the water intake.
The water is then directed to the safety spray pipe under
pressure from the high pressure pump.
The high pressure spray is formed through the nozzle on
the spray pipe.
Detergent and caring system
The high pressure pump can also suck a detergent/caring agent and mix it with the
high pressure jet. - The detergent must have the ph-value 7-9 neutral.
Only open the dosing valve, if the chemistry sieve is placed in a
liquid.
The rules concerning the environment, refuse and ground water
protection must be complied with!
Pressure control and safety facilities
The pressure control valve allows full adjustment of the
quantity and pressure of the water.
The safety valve protects the machine from excessive
pressure and cannot be adjusted beyond the admissible
operating pressure. The setting nuts are sealed with lacquer.
Replacements, repairs, new adjustments and sealing operations
may only be performed by trained personnel.
