Safety Hints
When using this unit make sure always to observe
the applicable building and fire protection regula-
tions as well as the rules of the trade cooperative
association.
l
The unit may be operated only by those persons who
have been instructed accordingly.
l
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.
l
The unit may only be installed and operated in
rooms, when the air rate fed to the unit is sufficient
for combustion.
l
Make sure to install mobile liquid gas reservoir on a
solid ground and in a vertical position.
l
Liquid gas reservoir may never be used in a lying po-
sition while the unit is operating (gas leakage in the li-
quid phase).
l
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.
l
The unit is to be installed and operated on a solid
non combustible ground.
l
It is to be ensured that no combustible objects/
materials can be sucked in.
l
The unit may not be installed or operated in in-
flammable and explosive surroundings.
l
A safety zone of 1.5 m around the unit and a mini-
mum distance of 3 m at the unit’s exhaust opening
are to be observed, even regarding non combustible
objects.
l
The unit’s exhaust opening may not be reduced or
equipped with hoses or pipings.
l
Make sure not to introduce foreign matters into the
unit.
l
The air suction lattice is always to be kept free from
dirt and loose objects.
l
Make sure not to expose the unit to direct water jets.
l
All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
l
Make sure to cut off the gas supply and to pull the
mains plug out of the mains socket when mainte-
nance and repairs are carried out.
l
Safety devices may be neither bridged nor
blocked.
General Hints
²
The unit may be operated only by those persons who
have been instructed regarding the unit’s operation
and the handling of liquid gas.
²
When using the unit make sure always to obser-
ve the guiding principles of the countries and
states concerned.
²
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 possibili-
ties 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.
²
A uniform unit connection pressure of 1.5 bar
(1500 mbar) of the category I 3B/P is necessary
for all the countries of the European Community.
The connection pressure may not fall below or
exceed the required value.
²
Make sure to use exclusively components, such as
gas hose, pressure controller and hose security devi-
ces (protection against breakage) or safety devices
against gas leakage, that have been tested and are
suitable for the intended purpose. The pressure con-
trollers must have a firmly regulated initial pressure
of
1500 mbar
and are to be equipped with a security
device against hose breakage.
²
Hose pipes are to be protected generally against
chemical, thermal and mechanical damage.
²
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 opera-
tion is to be stopped!
²
The unit may be only maintained by trained persons
and only original spare parts may be used.
²
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.
