Motor protection switch
Thepump motor is protected from overloadby a motor protecting switch. Incase 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
malfunctionhastobe removed.
Replacement and inspection work may
only be performed by trained personnel.

Water system
The water flows into a tank.
Afloatvalve(a) regulates the waterintake.
The water is then directed to the safety spray pipe under
pressurefromthehighpressurepump.
Thehighpressuresprayis 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
highpressurejet.-The detergent must have theph-value7-9neutral.
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
Thepressurecontrolvalve allows full adjustmentofthe

Spray pipe with spray gun
The spray gun only allows the machine to
beoperatedwhenthesafetytrigger is
pulled.
Thesprayguncanbeused when the safety
triggerispulled.Themachineisstartedand
the liquid transported to the nozzle. Spray
pressure builds up and quickly reaches the selected operating pressure.
When the trigger is released the gun is closed, which prevents any further liquid
from coming out of the spray pipe and the motor is stopped.
After completing work with your Kränzle therm CA, or if work is
interrupted, the safety catch (1) must be applied. This makes it
impossible to press the trigger by accident.
The spray gun is a safety device. Repairs may only
be performed by trained personnel. If spare parts
are required, use only those approved by the maker.
