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.
4
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.

Description
Spray pipe with spray gun
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 machine is started and
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.
5
Thermostat
The thermostat with rotary control
switch controls the temperature
of the spray water .
Use the rotary control switch to adjust
the desired water temperature.
Thermostat with rotary
control switch
High pressure hose and spray equipment
The high pressure hose and spray equipment supplied with the machine are made
of high quality material specially adapted for the operating conditions of the
machine, and are properly marked.
If spare parts are required, only properly marked components
approved by the maker should be used. High pressure hoses and
spray equipment must be connected so that they are pressuretight. The high pressure hoses should not be driven over , pulled
excessively or twisted. Do not pull the hose over sharp edges,
since this will invalidate the warranty.

Heat exchanger
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.
The pre-heated air is pressed through a mixing unit (4). Here finely atomized fuel is
injected via a nozzle (5) and mixed with the air . The electrodes (6) located below then
ignite the fuel-air mixture.
The flame burns from top to bottom, turns round and the hot gas flows past the heating
coil (7) on its way back up. The burned gases collect in the exhaust chamber and are
emitted from the chimney (8).
The water is forced through a heating coil by the high pressure pump. Hot air flows
around the coil, as described above.
The fuel pump (9) draws the oil through a filter (10) and pumps it to the injector nozzle
(5). The surplus quantity of fuel flows straight back into the tank. The oil pressure is
shown on the fuel manometer (1 1).

Safety Information
Important !!!
The machine must be disconnected from the power supply
when servicing 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 necessary 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.
Do not damage the cable or repair it incorrectly .
Do not pull the high pressure hose if there are kinks or loops in it. Make sure that
the hose is not damaged on sharp edges.
Persons operating the machine should wear the necessary protective clothing, i.e.,
waterproof 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. The gun must therefore be held firmly with both hands. (see page 2)
Do not close off the exhaust aperture on the topside of the machine. Do not
bend over this aperture and do not put your hands inside it. Exhaust gases are
very hot!
Do not clamp down the trigger of the gun. Apply the safety catch after use, in order
to prevent accidental spraying.
Do not spray against matter containing asbestos or other hazardous substances.
Never spray liquids containing solvents, such as paint thinner , petrol, oil, or anything
similar. Note the specifications of the additive makers! The seals in the machine
are not resistant to solvents. The spray vapour of solvents is highly inflammable,
explosive and poisonous.

The voltage given on the specification plate must match the mains voltage. You can
find the specification plate on the front right-hand side of the appliance.
The machine is supplied with a power cable and plug.
The plug must be connected to a properly installed electrical so-
cket with earthing and have a 30 mA FI residual current circuit
breaker. The socket must have a neutral 16A fuse on the mains
side.
If an extension cable is used, it must have an earth line that is properly connected to
the plug connections. The lines in the extension cable must have a cross section of at
least 1.5 mm². The plug connections must be of spray protected design and may not
lie on a wet surface. (If the extension cable is longer than 10 m the minimum cross
section is 2.5 mm²)
Important!
Extension cables that are too long cause a drop in the voltage and
thus interruptions in operation. If you are using a cable drum, the
cable must always be fully unwound.
Commissioning
Secure the machine by applying the brake (see page 8)
and check the oil level of the high pressure
pump.

Water connection
Connect the machine to a water tap using a hose of at least 1/2" and turn on the
tap. (2-10 bar admission pressure)
The water tank in the machine fills up. When the tank is full, the built-in float valve
closes the water inlet.
Use clean water only!
CAUTION !
Please pay attention to the regulations of your waterworks company .
In accordance with EN 61770, the machine may not be directly connected to the
public drinking water supply lines.
A brief connection however is permissible according to DVGW (German Association
for Gas and Water Affairs) if a tube ventilator with check valve (Kränzle Order-No.
41.016 4) is built into the water supply .
Also indirect connection to the public drinking water supply lines is permissible by
way of free emission in accordance with EN 61770, e.g. by using a reservoir with a
float valve.
Direct connection to a non-drinking water supply line is permissible.
High pressure connection
Connect the high pressure hose to the handgun.
Unwind the hose so that it is free of loops and connect it to the handgun and the
machine.
Check that all screw-type connections are pressure-tight. Leaks
from gun, high pressure hose or hose drum must be eliminated
immediately. Leakage leads to increased wear.

- The detergent must have the ph-value 7-9 neutral.
- Wait until the pump has pressed the air out of the lines.
- Put the chemical filter into a container with detergent.
- Open the detergent valve (20). The pump now sucks detergent in and mixes it
with the high pressure spray.
- Set the desired concentration of detergent.
- At the end of the working procedure with detergent reset the rotary button
to „O“.
- When the high pressure cleaner is operated with open chemistry valve
without chemicals, the pump sucks in air. Damages caused to the pump as
a result are not covered by the guarantee.
Comply with additive manufacturers’ instructions (e.g. protective
equipment and waste water regulations). Use only additives approved
for use with high pressure cleaners. Using other additives 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 by
pressing the trigger of the spray gun.

Decommissioning
- Switch off the master switch (position "0").
- Pull the plug out of the power socket.
- Turn off the water supply.
- Open the gun until the pressure is gone.
- Lock the gun.
- Disconnect the water hose.
- Slacken the connections of the high pressure hose and gun and unscrew the high
pressure hose from the machine (appliances without hose drum).
Anti-Freeze Protection
The machine is normally still partially filled with water after work has been completed.
It is therefore necessary to take special precautions to protect the machine from frost.
- Completely empty the machine of water
Disconnect the machine from the water supply and switch off the ignition.
Switch on the master switch and open the gun. The pump now presses the
remaining water out of the heating coil. Do not allow the machine to run for
longer than a minute without water.
- Fill the machine with anti-freeze
If the machine is not in use for lengthy periods of time, it is advisable to
pump anti-freeze into the machine, especially in winter. For this purpose, fill the
antifreeze agent into the water box and turn on the machine without ignition
(rocker switch (16) to „0“). Wait with opened gun, until the agent comes out of
the nozzle.
However, the best protection against frost is to keep
the machine in a place that is safe from frost.
