Safety Instructions
Please make sure that the relevant local building
and fire protection codes as well as the regulations
of the employer's liability insurance associations
are observed when the units are used.
◊
The units may be operated only by persons who
have been trained in this field.
◊
The unit is to be installed and operated in such a
way as to ensure that the employees are not endan-
gered by waste gases and radiation heat and that no
fire can break out.
◊
The unit may only be installed and operated in
rooms, when the air-rate fed to the unit is sufficient
for combustion.
◊
Without an exhaust system, the unit may only be op-
erated in well aerated rooms. The permanent stay of
persons in the room where the units are installed is
prohibited.
Appropriate prohibition signs are to be fitted at the
entrances.
◊
Mobile fuel reservoirs may be installed only when the
technical rules for combustible liquids are observed.
◊
The unit is to be installed only on a non-combustible
ground.
◊
The unit may not be installed and operated in inflam-
mable and explosive surroundings.
◊
A safety zone of 1.5 m around the unit, as well as a
minimum distance of 3 m from the unit's blower ap-
erture is to be maintained, even in the case of non
combustible objects.
◊
The blower aperture of the unit may not be narrowed
or equipped with hoses and conduits.
◊
The protective air suction grille is always to be kept
free from dirt and loose objects.
◊
Make sure not to introduce foreign matters into the
unit.
◊
Make sure not to expose the unit to direct water jets.
◊
All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
◊
Make sure always to pull the mains plug out of the
mains socket when maintenance and repairs are
carried out.
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.
