Safety hints
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 units are to be installed and operated in such a
way as to ensure that the personnel is not jeopardi-
zed by waste gases and radiation heat and that no
fire can break out.
The units may be installed and operated in rooms
only if sufficient air can be fed to the units to ensure
perfect burning.
Fuel may be supplied only based on the VGB 21
regulations (use of liquid gas).
Make sure that mobile liquid gas holders are instal-
led in a stable way and in an upright position.
During the unit's operation liquid gas holders are not
to be used in a lying position;
(gas leakage in the liquid phase!).
The units may be operated only in well aerated rooms.
The permanent stay of persons in the rooms where
the units are installed is prohibited. Appropriate
prohibition signs are to be fitted at the entrances.
The units may be installed only on a non-combusti-
ble base.
The units may not be installed and operated in en-
vironments which are endangered by fire and explo-
sions.
A safety zone of 1.5 m around the unit, as well as a
minimum distance of 3 m from the unit's blower
aperture 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 or conduits.
Never place foreign matters/objects into the unit.
The air suction grid must be free from dirt and loose
objects.
The units may not be exposed to direct water jets.
All electric cables outside the unit are to be protected
from damage (e.g. caused by animals, etc.).
When maintenance work and repairs are carried out
the gas supply is to be cut off and the mains plug to
be pulled out of the mains socket.
Safety devices may be neither bridged nor blocked!
When the units have been installed
and connected, all gas bearing con-
nections are to be checked to ensu-
re that they are tight (soap solution,
leakage detection spray).
Connect the pressure controller to
gas cylinder(s) or supply plant.
Attention!
left-handed thread!
Open the cylinder valve(s) or stop
valve of supply line. If gas is taken
out of several gas cylinders simul-
taneously all the valves are to be
opened.
Press the unlocking button of hose
shearing pin after having opened
the valve(s).
This must also be done each time
when having replaced the cylinders.
Gas supply
The gas supply/operation of the unit may be carried out
only based on the safety regulations VBG 21 as well as
on the applicable local building and fire protection codes.
The units have been conceived for a constant supply
pressure of 1.5 bar (liquid gas according to DIN 51622
Kat I
3B/P
, I
3+
).
A higher or lower supply pressure is inadmissible. When
longer hoses or conduits are used the resulting loss of
pressure is to be taken into account. Only tested compo-
nents, such as gas hose, pressure controller, hose
shearing pin or gas leakage safety device, which are sui-
table for the intended purpose are to be used. Only pres-
sure controllers with firmly set outlet pressure are ad-
missible.
The units may be operated only based on the gas pha-
se.
A constant gas supply pressure of 1.5 bar
(1500 mbar) is to be ensured, even under
continuous duty!
