When using this unit make sure always to observe the applicable building and fire protection regulations as well as the rules of the trade cooperative association.
The unit may be operated only by those persons who have been instructed accordingly.
The unit is to be installed and operated in such a way as to ensure that the employees are not endangered 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.
Make sure to install mobile liquid gas reservoir on a solid ground and in a vertical position.
Liquid gas reservoir may never be used in a lying position while the unit is operating (gas leakage in the liquid phase).
The unit may be operated only in well aerated rooms. Persons may not stay permanently in the room where the unit has been installed. Relevant prohibition signs are to be fastened to the entrances.
The unit is to be installed and operated on a solid non combustible ground.
It is to be ensured that no combustible objects/ materials can be sucked in.
The unit may not be installed or operated in inflammable and explosive surroundings.
A safety zone of 1.5 m around the unit and a minimum distance of 3 m at the unit’s exhaust opening are to be observed, even regarding non combustible objects.
The unit’s exhaust opening may not be reduced or equipped with hoses or pipings.
Make sure not to introduce foreign matters into the unit.
The air suction lattice is always to be kept free from dirt and loose objects.
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 to cut off the gas supply and to pull the mains plug out of the mains socket when maintenance and repairs are carried out.
Safety devices may be neither overbridged nor blocked.
!
The unit may be operated only by those persons who have been instructed regarding the unit’s operation and the handling of liquid gas.
When using the unit make sure always to observe the guiding principles of the countries and states concerned.
The unit may only be operated in rooms when
– the air rate fed to the unit is sufficient for com-
bustion and
– the rooms are well ventilated and deventilated
and
– the percentage of the substances which are
injurious to health in the breathed in air has
no inadmissible concentration.
A good and natural ventilation and deventilation is given if e.g. the room volume in m³ corresponds to at least 30 times the nominal heat load in kW of all the units being operated in the room, and if a natural air exchange through doors and windows is ensured, or if there are permanently open ventilation possibilities for ingoing and outgoing air near the ceiling and the floor, of which the size in m² corresponds to at least 0.003 times the nominal heat load in kW of all the units being operated in the room.
A uniform unit connection pressure of 0.3 bar (300 mbar) of category I
3B/P is necessary for all countries of the European Community.
The connection pressure may not fall below or
exceed the required value.
Make sure to use exclusively components, such as gas hose, pressure controller and hose security devices (protection against breakage) or safety devices against gas leakage, that have been tested and are suitable for the intended purpose. The pressure controllers must have a firmly regulated initial pressure of
300 mbar and are to be equipped with a security device against hose breakage.
Hose pipes are to be protected generally against chemical, thermal and mechanical damage.
The persons charged with the operation of the unit have to check it prior to starting work to make sure that there are no visible defects. If there are defects which affect the unit’s operational reliability, its operation is to be stopped!
The unit may be only maintained by trained persons and only original spare parts may be used.
If the unit has been switched off by the temperature limiter due to overheating, the reason for the fault has to be detected and eliminated.
#
Make sure to charge a person with the operation of the unit and with the supervision of the reservoirs and of the bottle stock who has been instructed sufficiently regarding the handlings concerned.
The persons charged with the operation of the units have to check the units before starting work to detect obvious defects on the operating and safety elements and to make sure that the safety devices have not been removed.
Make sure to draw the operators‘ attention to possible dangers during the handling of liquid gas.
Important Installation Hint
When installing or removing the gas hose make sure to exert a counterpressure on the gas connection nipple of the unit using an open-end spanner SW 19 and observing the left-handed thread.
1) Unscrew gas hose
Turn union nut clockwise
A constant unit connection pressure of
0.3 bar (300 mbar) must be ensured, also during continuous operation.
2) Fasten gas hose
Turn union nut anti-clockwise
Connect pressure controller to the gas bottle(s).
Attention! left-handed thread!
Open bottle valve(s).
When gas is taken out of several gas bottles simultaneously, all the valves have to be opened.
This procedure also refers to all further gas components, such as pressure controller, hose security device
(protection against breakage), etc.
When any work is carried out on the gas supply line and when the gas cylinder is replaced, all stop valves must be closed and there may be no ignition sources in the direct surroundings.
Press release button of the hose security device (protection against breakage) pened after having othe valve(s).
This has also to be done after each replacement of bottles.
After the installation and connection of the units all the gas bearing connections have to be checked with soap solution, leakage detecting spray etc. to make sure that they are tight.
Do not use open flames!
Hint!
Insufficiently dimensioned supply plants can cause icing of the pressure gas or pressure reservoirs. When the gas pressure falls a proper gas supply to the consumer points can no longer be ensured in many cases.
This will result in imperfect combustion, harmful waste gases or extinction of the flame. Therefore the supply plant is to be dimensioned in such a way as to ensure that problems of this kind cannot be caused.
The cristalline white frost may not be removed by open fire, glowing objects or radiators. Sufficient gas supply to the consumer points can be ensured by using an evaporator.
Sufficient gas supply is to be ensured according to the unit power rating (see identification plate), service life and ambient temperature of the supply tanks.
In principle, we recommend that you use a set of at least 3 cylinders to avoid intensive icing of the reservoirs.
The number of cylinders can be increased by using a set of several cylinders (accessories), depending on the unit capacity and the service life.
Install only in well ventilated rooms, not in rooms which people will be using for longer periods!

Assembly of Multi-bottle Set
To avoid intensive icing of the gas bottle during a longer operation of the unit, we recommend that you use a bottle battery consisting of at least 3 bottles. All bottle valves must be open to ensure regular gas supply!

After approx. 2 or 3 sec. the piezo igniter (3) is to be actuated (possibly several times) with the pin (2) still held down, until a formation of flames has occured.
Important!
Make sure to place gas reservoir only laterally behind the unit! Never heat up or defrost gas reservoir through the unit’s hot air current ( danger of explosion!
).
Never use gas reservoir in a lying position when the unit is operating (gas leakage in the liquid phase).
After the formation of flames still hold down the pin (2) for approx. 10 - 15 seconds, until the thermoelectric flame monitoring has started.
Do not release the pin before this.
If the flame is extinguished after the pin has been released, repeat the ignition procedure after having waited for approx. 1 minute. Then keep the pin pressed down a little longer.
Important Hints!
Make sure that the supply air can be freely sucked and the heated air can be blown off without problems.
The suction and blower apertures of the unit may not be narrowed or equipped with hoses or conduits.
Make sure to keep the safety distance from combustible and inflammable materials and to observe the local fire protection codes.
