 Description
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.
a
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.

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.

 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 1

be performed by trained personnel. If spare parts
are required, use only those approved by the maker.

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 pressure-
tight. 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.

 Description
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 (11).

 Safety Information
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.

Usage as a cold water high pressure cleaner
- Leave the ignition "OFF". Rocker switch (1A) to „0“.
- Start cleaning
Usage as a hot water high pressure cleaner
- Set the target temperature on the thermostat to min. 40 °C and than switch the
ignition "ON" (rocker switch).The oil burner starts to work. The water is heated up
and kept at the temperature you have set.
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.

Usage with detergents

- 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.

- 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.

 Care and Maintenance
Decalcifying the heating coil
Calcified machines use an unnecessary amount of energy because the water can only
be heated slowly and the excess pressure valve feeds a part of the water back into the
pump circuit.
Calcified machines can be recognised by increased pipeline resistance.
Check pipeline resistance by disconnecting the high pressure lance from the gun and
switching the machine on. A full jet of water emerges from the gun. The machine must
be decalcified if the pressure shown on the manometer is greater than 25 bars.
Decalcifiers are caustic!
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.
Wait for about a minute until the decalcifier comes out of the gun
(recognisable by its whitish colour).
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.

Cold water mode
1. Connect to water supply and determine whether the water tank fills up
completely and the float valve stops.
2. Ignition (2) to OFF.
3. Main switch (1) to ON.
4. Open high pressure gun. The apliance started, the pump sucks water from the
water tank and moves the water through the heating coil to the lance, the
pressure is increased.
ATTENTION!!
If the pressure is not built up immediately, there is still air
in the pump. Open and close the gun repeatedly to press
the air from the machine.

Hot water mode

Start the machine just like in cold water mode and then turn the rocker switch (2) for
the burner to ON. Then, turn the rotary switch on the thermostat, (4) located on the
front, to the desired temperature (at least 40 °C) in order to activate the burner, i.e.,
that fuel is injected.
The manometer (14) on the fuel pump shows approx. 10 bars. If this reading is not
displayed, check whether
1. there is heating oil in the tank
2. the motor fuse ( 11) in the switch box (below the operation panel) has tripped.
3. the fuel sieve (15) or the fuel sieve in the pump (13) is dirty.
4. the fuel pump does no operate smoothly or is blocked.
5. the ventilator jams.
The thermostat grants permission to open the solenoid valve. The burner starts and
heats up the water to the set temperature. The burner switches off as soon as the
desired temperature has been reached.
If the temperature drops again, the burner switches on automatically thus guaranteeing
the required constant temperature.

 Description of function -Troubleshooting
The thermostat (4) is controlled via a thermo-sensor (18) mounted at the outlet of the
heaiting coil.
In the switchbox (below the operating panel), a fuse (F1) is installed on the board
protecting the motor (11) of the fuel pump and the ventilator. If the motor is overloaded
the fuse trips. This may happen if the fuse pump is blocked or sluggish - the same
applies if the ventilator is blocked or sluggish or in case of an electrical malfunction.
Another fuse (F2) on the board trips, if the ignition transformer (17) is faulty.
To avoid an overheating of the burning chamber a flow indicator (10) is installed in the
high pressure system between the high pressure pump (6) and the burning chamber
enabling a fuel supply only if water streams through the heating coil at the same time.

Control board (p. 28-29)

The control board is equipped with two LEDs for trouble shooting.
L1: - permanently illuminated, if the overcurrent release has tripped.
- blinking, if the fuel flow valve detects only a low quantity of fuel in the tank or if
it is defctive.
L2: - illuminated, if the burner has been released but the flame is not burning. If the
flame starts burning within 2 seconds, the LED goes out.
If the LED does not go out the combustion has to be checked. If the LED is
not illuminated at all, the flame sensor has to be checked.
Nevertheless the cleaner can be used as a cold water high pressure cleaner
even if the burner is switched off.
