Description of Device
The unit is fired directly with heating oil EL or diesel and
can be operated with or without an exhaust-gas connec-
tion. It is intended for mobile and fully automatic deploy-
ment.
A fuel container is built under the unit and it is equipped
with automatic tank heating, a high-pressure atomizing
oil burner with optical flame monitoring, a low mainte-
nance axial ventilator, a connection cable with plug, a
room thermostat socket and a fivefold filter system.
The unit complies with the basic safety and health re-
quirements of the relevant EU stipulations and is reli-
able and simple to operate.
The unit can be used e.g. in the following areas:
-for drying new buildings;
-for point heating of outdoor workplaces;
-for point heating of workplaces in open, non fire-
hazard fabrication rooms and halls;
-for temporary heating of closed and open areas;
-for de-icing of machines, vehicles and non flammable
storage goods;
-for tempering frost-endangered parts.
Working of Device
The automatic tank heating is activated by connecting
the mains plug with a mains socket.
When the unit has been switched on or when heat is re-
quired (automatic function with room thermostat) the
supply air fan starts. The fan blows air into and along
the combustion chamber.
When the preliminary ventilation is over, the electro-
magnetic valve opens and supplies fuel to the nozzle.
The fuel, sprayed under high pressure, is enriched by
an adequate quantity of oxygen according to the heating
capacity and ignited by an electric spark.
Ignition is automatically terminated as soon as a perfect
flame burns and the flames are controlled by the auto-
matic burner relay. After a few seconds hot air is blown
out.
In case of any troubles, or if the flame is unstable or
tends to go out, the unit is switched off by the automatic
burner relay. The fault indicator warning lamp of the
automatic burner relay lights up. A restart cannot be
made before the manual release of the automatic
burner relay.
When the unit has been switched off via the operating
switch or the room thermostat, the supply air fan contin-
ues running for some time to cool down the combustion
chamber and then it stops automatically.
Depending on the required heat rate the function de-
scribed above is repeated automatically in the case of
an operation with thermostat.
G
On account of the construction type, a fixed-
location device installation is not permissible!
G
During the unit’s operation, safety devices may
neither be bridged nor blocked!
G
For optimum unit operation, the device should not
be operated at an ambient temperature above 25 °C.

5
Safety temperature limiter (STB)
The safety temperature limiter (STB) interrupts the
burner operation in the event of overheating and locks
all unit functions.
If the safety temperature limiter has triggered, the cause
of the disturbance must first be localised and elimi-
nated. Resetting via the "RESET" key is only possible
after the sensor has cooled to below ca. 90 °C.
The safety temperature limiter is unlocked by pressing
the reset key.
1. Detach the protection cap 1.
2. Press the reset key 2.
3. Replace the protection cap.

Provision for Air Heaters
For the deployment of the unit, the relevant guidelines
must be observed
1. Operating personnel
1.1 The unit must only be operated by persons who
have been trained in its operation.
2. Installation
2.1 The unit must be installed so that it can stand in a
stable position.
2.2 The unit must be installed and operated in such a
way that the employees are not exposed to the
danger of exhaust gases and radiant heat and that
the occurrence of fires is ruled out.
2.3 The unit may only be installed and operated in
rooms if a quantity of air sufficient for the combus-
tion is supplied to the unit and the exhaust gases
are removed to the exterior.
A natural air supply sufficient for the combustion is
present if e.g.
The room contents in m² correspond with at least
10 times the nominal heat load in kW of all the
units operating in the room and if windows and
doors ensure a natural change of air.
2.4 In deviation from point 2.3, the unit can be oper-
ated without an exhaust system in rooms if these
rooms have a sufficient air supply and are well ven-
tilated and if materials harmful to health do not
reach an unhealthy concentration.
2.5 A good natural air supply and ventilation is the case
if e. g.
The room contents in m² correspond with at least
30 times the nominal heat output of all units operat-
ing in the room and a natural change of air is en-
sured through windows and doors, or
openings which are not lockable are present in the
region of ceiling and floor for the air supply and for
out going air and the size of these openings in m²
corresponds with at least 0.003 times the nominal
heat output in kW of all units operating in the room.
2.6 The unit must not be installed or operated in rooms
and areas where the danger of fire or explosion ex-
ists.
3. Room drying
3.1 In deviation from point 2.3, in order to dry rooms
with an air supply sufficient for the combustion,
heating units can be operated without the exhaust
gases being removed to the exterior. In these
rooms, the permanent presence of persons is for-
bidden. Signs on the entrances to the rooms must
indicate that this is forbidden.
4. Examination
4.1 The unit must be tested by an expert as to its work
safety specific condition in accordance with the re-
quired deployment conditions but at least once an-
nually.
4.2 The exhaust values of the burner must be checked.
5. Monitoring
5.1 When starting work, the persons commissioned
with the operation of the unit must check the unit
for obvious defects or deficiencies on the opera-
tional and safety mechanisms and check that the
safety mechanisms are present.
5.2 If defects or deficiencies are discovered, the super-
visor must be informed.
5.3 In the case of defects or deficiencies which en dan-
ger the operational safety of the unit, its operation
must be terminated.
6. Installation in closed, well aerated rooms with-
out connection to a chimney
6.1 The operation of the units is admissible when the
minimum air quantity needed for combustion and
mentioned in point 2.5 is supplied.
6.2 A safe exhaustion of the waste gases is to be en-
sured to exclude inadmissible pollution.
Fresh air is fed from below;
waste gases are exhausted towards the top.
7. Correct usage
7.1 The unit are to be used only for heating purpose in
industrial or commercial application because of their
construction and equipment.
7.2 If specification of the manufacturer or legal regula-
tions, are not followed or if unauthorised changes
are made on the unit, the manufacturer is not liable
for resulting damages.

6
Malfunction-free operation is guaranteed if the exhaust
system is installed in an ascending direction and with
vertical end pipes.
The exhaust system must terminate at least above the
height of the eaves but better still above roof height in
order to avoid counter pressure caused by weather-
related circumstances (e.g. wind).
All exhaust-pipe parts must be attached reliably. Their
diameter must not be smaller than that of the exhaust
nozzle of the device (∅150 mm).
The minimum distance of 0.6 m to combustible parts
must not be exceeded.
Exhaust-pipe parts including attachment material are
available as accessories.
Exhaust system
In the outdoors or in open rooms, the operation of the
device is also possible without an exhaust system.
However, we recommend a 1 m exhaust-pipe (see ex-
ample 2) with a rain hood placed on top so as to rule out
the penetration by rainwater and dirt.
If the device is used for temporary room heating, the
combustion gases may have to be removed to the exte-
rior. The exhaust-pipe parts must be laid in such a way
that a minimum suction of 0.1 mbar is guaranteed.
G
It must be made sure in all cases that counter
pressure due to an incorrect exhaust system is
ruled out.

The unit is to be maintained regularly whereby some
fundamental rules are to be observed to ensure a long
service life and trouble-free operation.
After each heating period or even earlier, depending on
the deployment conditions, the entire unit including
combustion chamber and burner head must be cleaned
of soot sediments, dust and dirt.
The oil filters must also be cleaned / replaced at least
once a year or, depending on the degree of contamina-
tion of the fuel, frequently.
G
Setting and maintenance is to be carried out
only by authorised personnel!
G
Prior to starting any work make sure to pull the
mains plug out of the mains socket!

Exhaust Measurement
On account of the construction-dependent design of the
exhaust connection (connection nozzle with secondary
air openings), it is not possible to perform a correct ex-
haust analysis in a conventional manner in the exhaust
pipe behind the exhaust connection.
For the performance of the exhaust analysis the sensor
of the exhaust-measurement device must be placed in
the centre of the pipe socket of the heat exchanger.
The measurement sensor is placed through the appro-
priate lateral secondary air opening in the exhaust con-
nection in the existing measurement opening in the pipe
nozzle of the combustion chamber (see drawing below).
Adjustments of the burner head
◊Distance nozzle -air flow plate 4 mm
◊Distance nozzle -electrode tip 2 mm
◊Distance centre of nozzle -electrode tip 8 mm
◊Distance between the electrode tips 3-4 mm
Coarse adjustments of the air slide plate
1. Loosen the safety screw S.
2. Set the air slide plate Lby turning to an opening
width of ca. 25 mm.
3. Tighten the safety screw again.

Setting the pump pressure
The pump pressure can only be set if a manometer is
connected to the connection P. The pump pressure is
changed by turning the pressure setting screw A:
clockwise: increase the pressure.
counter clockwise: reduce the pressure.
The required pump pressure is determined according to
the heating capacity (please refer to unit type plate) and
to the nozzle size. The pressure setting screw "A" is to
be secured with the counter nut "B" after having set the
pressure.
Fuel Pump
The standard type of the pump runs in a system of
1 pipe. The required fuel is sucked in through the suction
line "S".
For the first starting and after having emptied the fuel
tank, the fuel system is deaerated through the burner
nozzle.
For this purpose the unit is switched on. After a possible
switch off through failure, the unit is restarted after hav-
ing released the automatic burner relay (take care of
waiting time).
If, after the 3rd start of the unit there is another switch
off through faults, the fuel filters should be checked to
make sure that they are free from pollutions and that
they are tight.
G
Perfect fuel quality is an absolute necessity for the
lubrication of the pump drive.
Suction of water residues should never take place
and, in the case of setting, suction should not take
place of warping fine dusts (e.g. cement etc.).
G
Never let the pump run without feeding fuel for a
longer period. Make sure not to leave a unit with
dry run pump unattended for a longer time.
