Description

Water system

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 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.

As an additional safety feature against overheating of the
combustion chamber a temperature sensor is installed in
the chimney. This sensor switches off the burner motor,
the ignition transformer and the solenoid valve as soon as
the exhaust gas temperature exceeds 250° C.

You find the unlocking button for the excess
temperature release on the console fixed to the
combustion chamber below the ignition transformer.

The machine has to rest for approx. 15 minutes before
it is allowed to press the unlocking button. If the
excess temperature sensor switches the machine off
repeatedly please call the technical service.

Replacements, repairs, new adjustments and sealing operations
may only be performed by trained personnel.

Description

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 the motor protecting switch. In case the
blue button is not set to „automatic resetting“, it has to
be pushed in again by hand. 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.

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 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.

After completing work with your Kränzle therm, or if work is interrupted, the
safety catch (1) must be applied. This makes it impossible to press
the trigger by accident.

Blue button in the
unfolded control panel

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.

Thermostat

The thermostat with rotary control
switch controls the temperature
of the spray water.

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.

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 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
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 (approx. 10
bar) 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 safety­relevant parts (e.g. o verpressure 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, ie, 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 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.

Safety Information

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 under water.

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.

Use light heating oil EL (DIN 51 603) or Diesel (DIN EN 590) only. The use of other fuel
is perilous and may even cause an explosion.

As to the recoil ­see notice on page 2!

Apply the safety catch on the

spray gun after each use, in

order to prevent uninten-

tional spraying!

Care and Maintenance

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 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.

freeze agent into the water box and turn on the machine without ignition (rocker
switch to „0“). Wait with opened gun, until the agent comes from the nozzle.

However, the best protection against frost is to keep

the machine in a place that is safe from frost.

Care and Maintenance

Care and maintenance is required to keep the machine in good working order, and
to allow you to enjoy the machine for as long as possible.

IMPORTANT!!!

Always remove the plug before working on the machine!

For this purpose, fill the anti-

What to do!

- Weekly, or after approx. 40 hours of operation

Check the oil level of the high pressure pump.
Loosen the red oil stopper on the high pressure pump and pull out the oil
measuring rod.

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 if it has a grey or whitish appearance. The oil should be
disposed of responsibly.

Check the filter in front of the float valve in the water tank and the fuel filter
in front of the solenoid valve. Clean the filters if necessary.

- Yearly, or after approx. 500 hours of operation

Desulphurise and decarbonize the heating coil.
Check the oil burner and ignition system

Clean the oil nozzle, oil filter, soenoid valve and filter, clean and adjust the
ignition transformer, ignition cable and ignition electrodes and replace defective parts

Care and Maintenance

Changing the oil

To do this, take the oil drainage hose (1)
connected to the oil drain screw, from the inside
of the machine and open the red oil filler cap on
the top side of the black oil reservoir. Open the
cap at the end of the hose. Drain off the oil into
an oil pan and dispose of it responsibly. Close
the end of the hose.
Refill with oil as described above.

Oil leakage

If oil leaks out, go to the nearest customer service immediately (dealer). (Environmen­tal damages, transmission damages, loss of guarantee.)

Type of oil: Formula RS of Castrol - Quantity: 1.0 l

Adjusting ignition electrodes

For a smooth ignition, the setting of the ignition electrode must be controlled
regularly.

Check distance in mm

Fuel System

Your fuel may contain particles of dirt, or impurities or water 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. Clean tank and fuel lines carefully and check to see whether
there are water droplets on the inside of the tank, because these must be removed.

Detergent and dirty fuel must be disposed of responsibly.

17

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 bar.

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 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
bar.

Description of function - Troubleshooting

Cold water mode

1. Connect to water supply and determine whether the water tank fills up completely
and the float valve stops.

2. Ignition (switch 1A) to OFF.

3. Main switch to ON.

4. Open high pressure gun. The pump sucks water from the water tank and moves
the water through the heating coil to the lance, the pressure is increased.

After you close the gun, press the red pressure switch (7). The 20-Second-Stop
system is activated, i.e. after closing the gun, the pump motor is turned off after 20
seconds. When you open the gun the motor starts again.

If the gun stays closed for more than 20 minutes, the safety switch off is activated
and the machine is turned off completely, i.e. if you want to use the machine you
must first turn it OFF and then ON with the main switch.

A TTENTION!!
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 for the
burner to ON. Then, turn the rotary switch on the thermostat, (2) 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 (15) on the fuel pump shows approx. 10 bars. If this display is mis­sing, check whether

1. there is heating oil in the tank

2. the fuse in the terminal box ( 11 ) for the motor ( 9 ) has blown.

3. the fuel sieve (22) or the fuel sieve in the pump (16) is dirty.

4. the ball cock (20) is closed.

5. the fuel pump does no operate smoothly or is blocked.

6. the ventilator jams.
The thermostat grants permission to open the solenoid valve; after opening the gun,
the burner starts. If the solenoid valve is open, the fuel pressure is approx. 10 bars.
The burner starts and heats the water to the temperature preset by you. When the
temperature is reached, the burner turns off. If the temperature drops again, the
burner switches back on automatically, so that you continuously have the desired
temperature.

Description of function - Troubleshooting

The thermostat with rotary switch is controlled by a thermosensor, mounted to the
outlet of the heating coil.

In the electro distributor box (11) mounted to the combustion unit, there is a fuse,
which protects the motor (9) for the fuel pump and ventilator. If the motor is overloaded,
the fuse blows. This can happen when the fuel pump is blocked or does not work
freely, when the ventilator is blocked or does not operate freely or when there is an
electrical problem.

There is a thermosensor (18) in the waste gas tube, which controls an excess
temperature relay with trigger function (4), i.e. when the exhaust gas temperature in
the chimney increases above 230 °C, this relay triggers. To activate it again, you must
wait until the combustion unit has cooled, i.e. approximately 15 minutes. Then, you
can press the button under the cover (14) again. The excess temperature relay can
trigger when the machine is operated over a longer period in the highest steam level, or
when there is lots of soot on the heating coil due to poor combustion, or when the
inside of the heating coil is calcified, so that there is no ventilation (cooling).

As further safety function, the burner is also switched off, when the water
temperature exceeds 147 °C.
