The water flows into a tank. A float valve 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 this nozzle on the spray pipe.
The high pressure pump can draw a detergent/caring agent at the same time and
mix this with the spray.
Only open the dispensing valve when the chemical filter is immersed in
the liquid.
The user must follow the respective environmental, refuse and
water protection rules!
Description
Water and Detergent/Caring Agent System
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.
The flow controller switches off the oil burner if the
water level is too low, thus preventing the heating
chamber from overheating.
There is a temperature sensor in the chimney as
an additional precaution against the combustion
chamber overheating. This device switches the
combustion motor, the ignition transformer and
the magnetic valve off as soon as the exhaust
temperature rises above 250°C.
The unlocking button for the temperature cut-out
is located on the console at the combustion
chamber below the ignition transformer.
The system must be left for approx. 15 minutes before the unlocking button may be
pressed.
Call customer service if the temperature cut-out actuates repeatedly.

Brake
The Kränzle therm is fitted with a brake that prevents the machine from rolling away
on flat ground.
Always apply the brakes firmly when working with the machine !!!
Brakes applied
Brakes not applied
Motor protection switch
The pump motor is protected from overload by a motor protection switch. This
switch cuts out the motor in the event of overload. If the motor cuts out repeatedly,
locate and eliminate the cause of the fault.
Replacement and inspection work may only be performed by trained personnel.
Flame monitor
The system is fitted with a flame monitor.
The flame monitor prevents fuel being injected if combustion is not taking place.
There is a temperature sensor in the exhaust chimney of the combustion chamber,
and it is connected to the central electronic control circuit.
The burner is switched off if the temperature in the chimney has not reached 100°C
within 37 seconds of the burner being started, or if the exhaust gas temperature
drops below 100°C for longer than 2 seconds while the engine is in operation. The
magnetic fuel valve is cut-out. The message "FLA" for flame monitor is shown on the
display of the control panel.
Call customer service if the system cuts out repeatedly because of the flame
monitor.

Description
Heat exchanger
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 inner and outer mantles are cooled. The pre-heated air is
pressed through a mixing unit (4). Here a finely atomised 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 element (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 element by the high pressure pump. Hot air
flows around this, as described above.
The fuel pump (9) draws the oil through a filter (10) and pumps it to the injector
nozzle. The surplus quantity of fuel flows straight back into the tank. The oil
pressure is shown on the fuel manometer (11).

Spray pipe with spray gun
2
3
The spray gun only allows the machine to be operated when the safety trigger (no.
1) 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 (trigger pressed) the pressure control valve
closes and the pump starts to operate again at the selected pressure.
If the gun is closed for longer than 20 seconds, the machine switches off. The pump
then restarts automatically when the gun is re-opened, provided the master switch
is on.
After completing work with your Kränzle therm , or if work is interrupted, the safety
catch (no. 2) must be applied. This makes it impossible to press the trigger by
accident.
The spray gun has bulit-in pressure regulation. If
the red ring on the handgrip (item 3) is turned to
the right the pressure reduces, and it increases
if turned to the left. But the manometer will still
indicate the pressure set on the control valve.
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.

Description
The thermostat controls the temperature of the
spray water. The target temperature is set using
two press-buttons (nos. 3 + 4) and can be read
from the top display (no. 1). If a button is held
down for longer, the target temperature setting
increases quickly in increments of 5°C.
The last temperature setting used remains
stored after the machine is switched off and
automatically becomes the default temperature
when the machine is switched back on.
The current spray temperature can be read from
the bottom display (no. 2).
When the machine is switched on, both displays show the figure "888" for approx 1
second to check the functioning of the units.
The thermostat also monitors the fuel level in the tank by means of a float switch. If
the fuel level falls below the minimum required quantity, the thermostat switches the
oil burner off and the word "OIL" blinks in the target temperature display window (no.
1). If the top display shows the letters "FLA" this indicates a malfunction in
combustion.

Safety information
IMPORTANT!
For safety reasons, the master switch must be put in the "0" position (ie,
the power must be switched off) after the washing process has been
completed.
At the start of the washing process the high pressure stream must be directed for at
least 30 seconds at the object being cleaned. It is possible for the water content
(approx. 5 l) of the combustion chamber to discolour during periods of disuse.

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.
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 be allowed to 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, ie, water-
proof clothing, rubber boots, safety goggles, headwear etc.
* 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.
* 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 anythng
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 machine may not be set up and used in rooms where there is a danger of fire or
explosion. The machine may not be used underwater.
* Air is required for combustion, and exhaust fumes are generated. If the machine is used
in closed rooms, make sure that the exhaust fumes can escape and that there is adequate
ventilation.

Decommissioning
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 element.
Do not allow the machine to run for longer than a miniute 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..
However, the best protection against frost is to keep the machine in a place that is
safe from frost.

Fuel System
Your fuel may contain particles of dirt, or impurities may get into the tank during
refuelling. Check the tank for impurities on a regular basis. Clean the tank when
necessary
Empty the fuel tank using the drainage screw at the bottom of the tank. Clean the
tank and fuel lines.
Replace the drainage screw.
Detergent and dirty fuel must be disposed of responsibly.
Care and Maintenance
Decalcifying the heating element
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.
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 spray emerges from the gun. The
machine must be decalcified if the pressure shown on the manometer is greater
than 25 bar.
CAUTION!!!
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 (eg, gloves, safety mask
etc.)
Proceed as follows to decalcify the machine:
* Unscrew the high pressure hose from the machine and decalcify these 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
bar.
