1. Description of the machine
1.1 Use:
The hot water cleaner is designed for high pressure washing using hot water and can deliver a flow of
between 14 and 30 litres of water per minute. The integrated pump can achieve a pressure of between
150 and 240 bar, depending on the model selected. For technical reasons, the pumps in the high-
pressure washers cannot operate in water temperatures above 60°C, so heating initially takes place
once the water has reached the correct pressure. In most cases, the water temperature can improve
the cleaning process on individual greasy surfaces.
The hot water cleaner requires a power supply of either 3 x 230 volts or 3 x 400 volts. See data plate.
The hot water cleaner may only be used with domestic water or recovered rain water with a purity level
equivalent to standard supply water. The addition of substances via a dosing unit can improve high
pressure cleaning and may only be added through this tool if the substances in question are suitable
for use at high temperatures under significant pressure. This form of cleaning requires that the condi-
tions for use for these cleaning agents are followed to the letter.
Heating takes place in a sealed combustion chamber in which standard diesel is constantly ignited by a
glow plug. The tank is fitted in front of the tool and can hold 20 litres of diesel.
The machine is normally controlled by a single operator and shall principally be used under supervi-
sion. It cannot be ruled out that the machine may be controlled by multiple operators. Therefore, clean-
ing must be carried out with care.
The hot water cleaner is relatively quiet, producing less than 70 dB. However, the operator must wear
ear defenders if it is judged that the noise levels produced during work will be damaging to hearing. In
other words, even at noise levels below 85 dB(A), ear defenders must be worn.
Examples of possible uses:
Engine and undercarriage cleaning in the automotive industry.
Contractor machinery.
Agricultural machinery.
Purification plant.
Farming.

1.2 Function:
The tool consists of an epoxy-coated steel frame and a stainless steel casing.
The hot water cleaner heats water in a combustion chamber where a blow motor, glow plug transformer
and temperature control ensure efficient heating.
The pump is fitted directly to the output shaft of the electric motor, affording a variable power of between
4.0 and 755 kW, or 5.5 and 10 hp.
Diesel is used as the fuel for heating the water in this tool. Use of other fuels is not permitted. A double-
sided, air-cooled steel boiler with a flow-through spiral ensures a very high level of efficiency with mini-
mal energy consumption. The environmentally-friendly combustion values, 10-11% CO2, soot concen-
tration 1-2. means that exhaust gases are channelled out through an opening in the top side of the tool,
which must not be covered.
The hot water cleaner is designed to be used outdoors or in well-ventilated rooms.
Water temperature is raised steplessly from 0° C to max. 80° C. In addition, a fuse is fitted to prevent
overheating, stopping the boiler when the temperature reaches108 / 109° C. Furthermore, a Flowmeter
stops heating if there is insufficient water, only allowing the hot water cleaner to start once water is back
in the pipes.
There are different models in the range, each of which is designed for a pressure between 150 and 240
bar. All models have same appearance, only the pump and electric motors differ from model to model.
Unauthorised repair and adjustment is not permitted as this can affect combustion and the development
of unwanted gases.
The side screens can be detached using rubber hasps, which makes it easy to service the unit. The boil-
er is double-skinned, allowing the surface around the boiler to be maintained at a temperature below 70
° c.

2. Instructions for use and maintenance instructions
2.1Preparation
The hot water cleaner is moved either using a truck connected directly to a pallet on which the unit is
secured or by attaching a crane lift in 4 lifting lugs. See section 4.1).
The weight of each model may vary between 135 and 190 kg without water.
Never lift the unit more than 0.5 m and never above persons. Connect power and water once the unit
is standing on a stable and level floor.
Make sure that personal protective equipment
is within easy reach. We recommend that pro-
tective clothing, goggles, gloves and safety
footwear are used whenever the hot water
cleaner is operated.
This unit has been factory tested and test operated, but transit may necessitate in the unit requiring fine
adjustment and a visual check of all functions. Always check for loose power wires, screws and defective
joints.
Always ensure work is conducted in accordance with good ergonomic principles and schedule breaks
during extensive and lengthy work tasks. Avoid overstressing your back and arms, and organise the
working day in consultation with management. Organise variations or adequate breaks in order to avoid
unilateral loads.
Check the oil level in the pump inspection window.
Check to see if it is possible to connect the correct mains voltage.
Check that the water filter is free from dirt.
Refill diesel in the tank (holds max. 20 litres) and, if necessary, fit any missing side walls.
Connect the water supply to the hot water cleaner using a ¾" web-reinforced hose. Use tap water or
"reject water" (purified waste water), if this is available.

2.2 Operation
Before starting:
Remove objects or goods which may be damaged during high pressure cleaning.
If the hot water cleaner is on sloping terrain, set stop blocks under one of the wheels.
The pressure washer must be used only on a ladder where a platform ladder with guard rails is
available. The height of the platform shall not exceed 3 m. The platform ladder must be designed in
accordance with the principles of EN 131, or have an equivalent safety level.
Connection of the high-pressure section:
1. Fit one end of high pressure hose to the gun. The other end is to be fitted to the unit’s discharge
port. Fit the spray nozzle to the gun.
2. Before using the machine, check the high-pressure hose for breaks. In instances where controls
are replaced, the replacements must have the same specifications as the originals. The technical
specifications (max. working pressure, date of fabrication and manufacturer) must be stamped on
the hose.
Connection of water supply:
1. Connect a reinforced water hose with 19 mm int. dia. (3/4 ") to machine input.
2. Please note, the water supply must be shortened to match the length of the supply hose.
Important:
Please ensure that the water entering the machine is totally clean. Use of the machine without water or
with water that is contaminated with sand or corrosive materials will destroy the pump.
Connection to electricity supply:
1. Check that the mains voltage is the same as that specified on the type plate on the machine.
2. Make sure the power cord is legal in accordance with Danish standards and is earthed.
3. Do not connect other machines to the same power socket.
4. Before using the machine, check the power cord for breaks. If a break is found, the power cord
must be replaced by a qualified person. Only a cord of the same type as the original may be used.
The cord is labelled on the outside. Do not attempt to perform repairs on the power cord.
5. Once you have checked that the switch on the machine is in the OFF position, connect the plug to
the power socket.
Only persons over the age of 18 may operate this machine.
(Danish At Guidelines D 2.20 November 2006):
Young people who are subject compulsory education requirements must not work with pressure equipment.
Young people over the age of 15 who are not subject to compulsory education requirements must, as a general rule,
not work with pressure equipment at a pressure in excess of 7 MPa (70 bar).
However, young people over the age of 16 who are not subject to compulsory education requirements may work
with pressure equipment at a working pressure in excess of 7 MPa (70 bar) within agricultural and gardening
applications. The pressure equipment may only be used for cleaning, painting, application of anti-corrosion agents,
etc.
Young people under the age of 18 may not work for more than 4 hours per day using air-supplied respiration
equipment.

Check whether the water supply to the tool is connected correctly.
Remove objects or goods which may be damaged during high pressure cleaning.
Set the hot water cleaner’s thermostat to 0°.
Turn on the water.
The hot water cleaner can also be used as a regular cold water cleaner, which can be activated by turn-
ing the switch on the control panel to the "1" position, thus preventing the boiler from engaging.
Turn the switch on the hot water cleaner to the "2" position to start the burner and set the thermostat at
the desired temperature (0 –80° C). The boiler will start heating the water and, after a short period of
time, high pressure washing using hot water can begin. The temperature can be adjusted on an ongoing
basis using either the thermostat or the red knob. The less water, the higher the temperature.
Never pull the machine's electrical cables or high pressure hoses.
Remember, hot jets of water under high pressure have a wrenching effect on
sensitive surfaces.
Never turn the jet on yourself or towards other people or animals. Even at lower water temperatures, the
cleaner may not be used to give “baths" to animals as the water jet can cause serious damage to areas
that it comes into contact with. Sensitive areas such as the eyes and ears can suffer severe and painful
damage.
Electrical installations and live electrical cables must not pressure washed.

Take steps to ensure that flammable objects do not come near the exhaust pipe.
Indoor high pressure cleaning is only permitted in well-ventilated rooms. If you feel unwell during clean-
ing, you must immediately stop work and go out in the open air. In addition to the inhalation of exhaust
gases from the machine, nausea may also be induced by any cleaning agents that may have been
used during the washing process. Therefore, you should thoroughly investigate whether these mat-
erials have been used correctly from both a safety and an environmental perspective. This information
can usually be found on the packaging that accompanied the cleaning agent. Never try experimenting
with additives that may be hazardous to human or animal health. If liquid gets in your eyes, rinse imme-
diately under running water and then seek medical attention. If possible, provide information about the
cleaning agent, e.g. bring the packaging, so that the doctor can determine the best course of treat-
ment.
Cleaning agents can vary in quality, and so steps should be taken to ensure that any cleaning agent
you use is suitable for use at high temperatures and under high pressure. Consideration should also be
given to the environment, particularly in instances where waste water will flow into untreated drains. If
necessary, obtain a datasheet pertaining to the cleaning agent on which its hazard class and personal
protection requirements are defined on a scale of 1-6, with 6 being the most hazardous! Never use
aggressive substances such as acids, thinners or explosives in this tool. If possible, switch to a less
corrosive cleaning agent.
Even if the hot water cleaner has only been operated using “clean” tap water, never drink water from
the machine as the bacteria content may have increased and be left over from a previous heating.
The heated water from the hot water cleaner must not be used in connection with the production or
preparation of food as machines used in the product of foods are subject to some extremely strict
requirements.
Loss of water or power will not damage the hot water cleaner as both types of situation are mitigated
by the unit’s integrated control system. Once the water and/or power supply has been re-established,
the cleaner will start heating again.
Never leave the hot water cleaner running unsupervised.
Turn the thermostat to 0° C and pull the gun trigger for approx. 1 min to allow the boiler
and spiral tube to cool. Turn off the water supply and open the piston in order to drain
water from the system and depressurise the hose. Turn the switch to the “0” position
and disconnect the plug from the power socket.
Frost protection is done by disconnecting both connecting pieces so that all the water in the unit can
run out or using the antifreeze method described later in this document. The high-pressure washer is to
be protected against frost in accordance with this User Guide.

Respiratory Equipment/Ear Defenders (Danish At Guidelines D. 2.20 November 2006):
When working under 2.5 MPa (25 bar) and if there are aggravating factors such as chemicals that are harmful to
health when inhaled, micro-organisms or residues of organic origin present, the employee shall wear appropriate
respiratory equipment.
Appropriate respiratory equipment shall always be used when working over 2.5 MPa (25 bar).
Respiratory equipment must feature a filter of at least class P2, which provides protection against solid particles
and liquid aerosols. The safest thing to do is to use respiratory equipment with an on-board air supply. There can
often be doubt as to the nature and concentration of air pollution, because it can be difficult to determine what
materials are removed from surfaces that have been pressure-washed. If the employee is to spend more than
three hours a day working with a pressure washer, the respiratory equipment used must have an on-board air
supply or feature filtration supplemented by a turbo unit (fan).
Inhalation of aerosols containing surfactants (e.g. soap) and grease and protein residues heightens the risk of the
development of respiratory ailments and is also a mucosal irritant (3).
The employer shall ensure that employees use ear defenders as soon as work that is deemed to be damaging to
hearing begins. In other words, even at noise levels below 85 dB(A), ear defenders must be worn (4).
Respiratory equipment and ear defenders must fit together, and should preferably be tested together.
Class P2
filters have better filtration characteristics and therefore provide more extensive protection. They protect against
harmful and toxic dust, but not against radioactive dust, bacteria and viruses. These filters can protect only
against solid particles or against both solid particles and liquid aerosols. If the filter has been certified in accor-
dance with EN149:2001, it affords protection against both solid particles and liquid aerosols. For more information,
see At Guidelines D.5.4 January 2008.
Filtering respiratory mask.
Particle filters are divided into three
classes: P1 low effect filter
P2 medium effect filter
P3 high effect filter
Respiratory equipment with on-
board air supply
At Guidelines D.5.4 January 2008:
Filtering face mask.
When planning work, it must be remembered that aerosols, especially small particulate, remain in the
air for a long time, even after pressure work has stopped. Therefore, it will often be necessary to use
personal protective equipment, even after pressure work has stopped. The smallest aerosol particu-
lates can remain in the air for up to 1.5 hours.

Important.
Only use biological chemicals with a pH value of between 7 and 12. These chemicals must be com-
pliant with the laws and regulations of the countries in which they are used. The use regulations for
this machine must be strictly adhered to. Everything else is deemed to be incorrect. The manufac-
turer may not be held liable for any accidents resulting from incorrect use of the machine. This mach-
ine must not, under any circumstances, be taken apart. If the machine is taken apart, the manufactur-
er disclaims all liability in connection with the use and safety of the unit.
Check of water filter.
It is important to check the water filter before starting the machine. Remember, a cleaned water filter
has a longer service life and means that the machine can operate for longer periods.
Precautions in the event of storage/frost:
If the machine is to be stored in a place where there is a risk of frost, or it to remain unused for more
than 3 months, it is advisable to fill the pump with antifreeze of the same type as used in cars. In low
temperatures, it is possible that some parts will freeze or seize up if the machine has been stored for a
long period of time. Therefore, we suggest that you turn the shaft using the key supplied with the
machine before starting the unit again. This enables the user to check whether the machine is frozen or
is blocked for other reasons. By following these rules before starting, you will avoid the possibility of
destroying the machine. Remember to remove the key from the shaft before starting.
General precautions for use:
1. Keep the machine out of reach of children.
2. The high-pressure jet is dangerous if used incorrectly. In particular, the water jet must not be
directed at persons, animals or electrical components, or at the machine itself. Do not use the
machine if people or animals are within the range of the jet.
3. The user must handle the machine in such a way that he does not constitute a danger to himself or
other persons.
-In particular, the user must avoid working in uncontrollable positions.
-Remember, the high-pressure jet may produce recoil when the gun is open. The pressure
produced by the recoil is less than 20N, approx. 2 kg.
-Use waterproof clothing.
-Use safety goggles and non-slip rubber boots.
-Avoid coming in contact with toxic materials.
4. This machine has been manufactured in accordance with electrical safety regulations.
-In any case, caution shall be exercised when using electrical machinery and, in particular, the
user must not touch electrical parts or components
-All servicing and repairs shall be carried out by a qualified person. Before servicing and repairs
are carried out, the plug must be disconnected from the mains power supply.
-In instances where an extension cord is to be used, steps must be taken to ensure that joints are
watertight and are kept off the ground in order to avoid contact with the water.
5. Do not pull the power cord to disconnect the plug from the mains power supply.
6. Whilst in use, the machine must not be covered nor placed in a location where there is no ventilation.
7. Never allow the machine to run for more than 5 mins with the gun closed as the water in the pump
may become heated and destroy the pump.
8. When the machine is not in use, the trigger on the gun should be locked so that it cannot be opened
accidentally.
9. For safety's sake, use only original spare parts and accessories.
- If the nozzle is to be replaced, the machine must first be turned off and pressure accumulated in

Even if the high-pressure washer has only been operated using “clean” tap water, never drink water
from the machine as the bacteria content may have increased and be left over from a previous heating.
Hot water that has passed through the high-pressure washer must not be used in connection with the
production or preparation of food as machines used in the product of foods are subject to some
extremely strict requirements.
Frost protection.
The cleaner must be stored in a frost-free environment. If this not possible, protect the pump and pump
components in the following way:
Fit one end of a short 3/4" hose to the water inflow and place the other end of the in a 5l of methylated
spirits. Start the cleaner, open the gun and close again once the methylated spirits start coming out of
the nozzles.
If the machine has been exposed to frost, never start it before it has been
completely thawed. Allow your dealer to check for any damage.
Important.
After using chemicals/soap, the injector suction hose and check valve MUST be flushed with clean
water. Place the injector suction hose in a bucket or similar vessel containing clean water, and allow the
injector to suck up water for a few minutes.
Never direct the jet towards electrical installations or living objects.
Never pull the machine by electrical cables or high pressure hoses as this may
result in the machine’s components being damaged and invalidate the warranty.
Because it is under high pressure, the water jet has a cutting effect on delicate surfaces.
Never turn the jet on yourself or towards other people or animals. Even at lower water temperatures, the
cleaner may not be used to give “baths" to animals as the water jet can cause serious damage to areas
that it comes into contact with. Sensitive areas such as the eyes and ears can suffer severe and painful
damage.
Electrical installations and live electrical cables must not pressure washed.
Stop the machine.
Shut off the water, open the gun and allow the machine to run for 15-30 seconds.
Disconnect the motor protection device.
Purge hose pressure.
Disconnect the power plug.

7. The hot water cleaner must not be covered as the exhaust gases
emitted will be very hot.
8. If necessary, make sure that there is good exhaust gas ventilation.
9. Never direct the water jet towards yourself, other people or animals.
Cleaning of clothes.
10. Avoid spraying electrical wiring and installations.
11. Be careful around sensitive and expensive installations.
12. Avoid cleaning parts that have contact with food.
13. Use only approved cleaning agents that are designed for hot water
cleaning.
14. Dispose of empty packaging at an approved local authority waste
reception centre.
15. If necessary, use respiration equipment if there is a risk of inhaling
harmful vapours. See the hazard class shown on the cleaning agent
packaging.
16. Frost may result in pipes bursting, immediately destroying the hot
water cleaner. The machine must always be stored in a frost-free
location. If this is not possible, protect the machine against the
effects of frost as described in the next section of the User Guide.
17. Hot water cleaning in freezing weather requires immediate start-up,
after which the hot water must be use immediately. Please note that
cleaning may cause ice accretion.
18. Never leave the hot water cleaner running unsupervised.
19. If necessary, the hot water cleaner can be prevented from moving
using stop chocks.
20. Nobody must be present under a hot water cleaner that is being
lifted.
21. Any repair or adjustment must only be carried out once steps have
been taken to ensure that the main power is secured against
unintentional start, e.g. disconnect the plug from the power
socket.
22. Incorrect installation and handling may result in serious accidents.
Changes to the machine's functionality are made at your own risk. Deterioration of health and safety
functions may put the owner of the machine in a legally untenable position, particularly where changes
or decisions taken have resulted in personal injury. As a rule, significant changes require a new CE
marking on the hot water cleaner.

Any repairs or adjustments may only be carried out when the main switch is locked and when the hot
water cleaner is secured against accidental start-up. A removable power plug also provides an extra
layer of safety for the person conducting repairs.
Make sure that all pressure is equalised before disconnecting high pressure pipes and hoses.
3. Maintenance guide
3.1 General maintenance
During each start-up:
Conduct a visual check of the hoses for wear and tear.
Conduct a visual check for diesel leaks.
Conduct a visual check for a blocked exhaust.
Conduct a visual check for water leaks.
Monitor for thermostat stop.
Check for any noise from blow motor/motor bearings.
Once a year:
Perform a visual inspection of the chassis and lifting bracket. Look for cracks and loose bolts.
Test the thermostat by measuring the temperature. Heating must stop at 80° C.
Test flow meter.
Inspect exhaust pipes for signs of soot build up.
Thread collection by supply and discharge port.
Seals at all electrical installations.
Review of chassis for signs of rust and impact damage.
Evaluation of exhaust smoke - possible measurement of carbon ratio and CO2 level.
Apply a thin layer of lubrication to the wheel hubs if necessary.
Frost protection:
Drain the hot water cleaner by disconnecting the supply and discharge pipes, allowing the water to run
down the spiral pipe into the boiler. Tip the machine slightly in order to ensure that all the water runs
out.
Alternatively, coolant may be sucked into the pipe system through the cold water connection until the
fluid comes out of the nozzle on the spray gun.
Descaling:
Descaling is to be carried out as necessary and it is important in order to prevent clogging of the spiral
pipe in the boiler. Fill with water and acetic acid in a ratio of 1 part acetic acid to 10 parts water, and
allow to stand for a few hours. Flush out the loosened scale and dirt. In extremely hard water areas,
additional treatment may be necessary in order to avoid future clogging of spray gun nozzle.

The machine itself can withstand immersion in water, e.g. in a standard car wash, whereas electrical
components may only be cleaned using high pressure air and wiping with clean rags. Only clean whilst
the unit is cold.
Paint damage can be repaired by grinding and then applying layers of base coat and top coat
(1-component top coat).
Once the hot water cleaner has reached the end of its service life, it must be disposed of in accordance
with local authority scrappage regulations applicable at the time.
Combustion chamber:
The combustion chamber is to be inspected as necessary, or at least every 2 years, along with the
nozzle and check electrode.
The easiest way to clean the chamber is to insert a long brush and then vacuum out the loosened
debris. Finish cleaning by conducting OR test, which is to be carried out by an authorised technician.
Comply with national requirements, which may vary from country to country.
General:
Repeated fuse trips may be attributed to errors in the control system or electronic devices, and
incorrect current may cause electric shock. (230 Volts or 400 Volts)
Repairs may only be carried out by an authorised installer who is able to locate the fault and carry out
appropriate repairs before the hot water cleaner is put back into use.
Diesel nozzle:
The nozzle must be replaced as necessary, or at least every 2 years, following an inspection conduct-
ed by an authorised person. This is best done during an OR test and by an authorised technician.
Comply with national requirements.
Electrodes:
Clean electrodes are essential in order to achieve good operating economy and stable operation.
Therefore, we recommend that the electrodes are removed as necessary. or at least every 2 years,
during an inspection carried out by an authorised person. The entire starting assembly is located under
the top plate and, after a thorough cleaning (using a wire brush), check the following distances (see
drawing) before refitting. If the electrodes are burnt out, replace the entire starting assembly and, if
necessary, fit a new nozzle. This is best done during an OR test and by an authorised technician.
