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 pres-
sure and cannot be adjusted beyond the admissible opera-
ting pressure. The setting nuts are sealed with lacquer.

Excess temperature release
As an additional safety device the appliance is equipped
with an excess temperature sensor inside the chimney. Should

and the burner continues to heat although the heating coil does
not conduct away heat a destruction of the heating coil would be
inevitable. As soon as the temperature inside the chimney exceeds
260 °C the excess temperature release triggers and cuts out the
appliance.
The display of the excess temperature release is located on the
back of the switchbox inside the appliance.

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.

The spray gun only allows the machine to be
operated when the safety trigger is pulled.
The spray gun can be used when the safety
trigger is pulled. The liquid is then pumped up 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.
The recoil resulting from the gun being closed opens the pressure control valve in
the machine. The pump remains switched on and pumps the circuit with reduced
overpressure. When the gun is opened the pressure control valve closes and the
pump starts to operate again at the selected pressure.
If the spray gun is closed for more than 20 seconds the motor switches off. The motor
restarts as soon as the safety trigger is pulled again.
If the gun is closed for more than 20 minutes, the safety switch-off is activated and
the high-pressure cleaner switches off completely, i.e. to be able to work with your
cleaner it has to be switched OFF and then ON again with the master switch.
After completing work with your Kränzle therm C, or if work
is interrupted, the safety catch (1) must be applied. This makes it
impossible to press the trigger by accident.

Heating coil: 34 m long - Content: 5 l of water – Heating capacity: 70 k W
The heat exchanger is heated by a high pressure fan heater.
A ventilator (1) draws in the cold, fresh air from the bottom end of the machine and
forces it upwards between the outer mantle (2) and the inner mantle (3). In the process,
the fresh air is pre-heated and the outer mantle of the heat exchanger is cooled.

Safety Information
CAUTION !!!
For safety reasons always put the master switch into the „0“
position (=power switch-off) after completion of work.
When starting the cleaning process do not aim the high pressure jet at
the object to be cleaned for at least 30 seconds.
It is possible, that the water contents in the combustion chamber (approx. 5 litres) has
changed colour due to the resting time.
Now you can
move the cleaner

Safety Information
Safety Information
IMPORTANT !!!
The machine must be disconnected from the power supply when ser-
vicing work is being carried out. The master switch should be in position
„0“ and the plug out of the socket.
Do not use the cleaner if electrical connections or other safety-relevant
parts (e.g. overpressure valve, high pressure hose, spraying equipment
etc.) are damaged.
The machine may only be used by persons who have received the neces-
sary training.
Never operate the machine without supervision.
The water spray can be dangerous. It should never be directed at people, animals,
electrical apparatus or the machine itself.
Never direct the spray at power sockets.
Parts of the machine interior and parts of the gun and lance become hot when hot
water is used. Leave the cover of the machine closed when using the machine and do
not touch the metallic parts of the gun and lance.
Children must not use high pressure cleaning equipment.

is not damaged on sharp edges.
Persons operating the machine should wear the necessary protective clothing, i.e., wa-
terproof clothing, rubber boots, safety goggles, headwear etc. It is prohibited to use the
machine in close vicinity to people lacking suitable protective clothing.
The high pressure spray can generate a high level of noise. If noise exceeds the maximum
allowed levels, users and others in the vicinity must wear suitable ear protection.
The high pressure spray causes recoil and additional twisting movement if the gun is angled.

Comply with additive manufacturers’ instructions (e.g. protecti-

approved for use with high pressure cleaners. Using other additi-
ves impairs the safety of the machine.
In the interest of the environment and to keep expenditure down,
we recommend sparing use of detergent. Please observe the
recommendations of the detergent manufacturer.
After using detergents, rinse the machine for approx. 2 minutes

During high-pressure operation (above 30 bars) the temperature may not
exceed 90 °C.
Steam level
To reach the steam level, i.e. over 90 ° C water temperature, adjust the pressure
and the water quantity downwards using the handwheel ( 4 ) and choose the desired
temperature of max. 150 °C with the thermostat. For high pressure cleaners with
hose drum applies: The hose must always be fully unwound.
During steam operation the pressure may not exceed 30 bars.

Check the oil level of the high pressure pump. (see page 13)
If the oil level is too low, add oil until the oil level is between the two markings on
the oil measuring rod.
Change the oil (see page 19) if it has a grey or whitish appearance. The oil
should be disposed of responsibly.

Observe the instructions for usage and accident prevention. Wear protective
clothing to prevent the decalcifying agent from contacting your skin, eyes
and clothing (e.g. gloves, safety mask etc.)
Proceed as follows to decalcify the machine:
Unscrew the high pressure hose from the machine and decalcify it separately.
Put the detergent suction hose into a container of decalcifying solution.
Set the dispenser valve to the maximum concentration.
Switch on the machine.
Hold the gun in a separate container and press the trigger.

Switch off the machine and allow the solution to act for about 15-20 minutes.
Switch the machine back on and rinse it through with clear water for about 2
minutes.
Now check whether pipeline resistance is back to an acceptable level. Repeat the
decalcifying process if the pressure without the high pressure lance is still above
25 bars.
