Danger of death! Gases are generated during the
storage of slurry which remain partly dissolved in
the liquid. If the slurry is strongly agitated during
mixing and purging, poisonous, explosive gases
such as hydrogen sulphide and methane are released. If an ignition source is present, the released
gas can explode.
To avoid damage during operation, please observe
the following:
–Switch off the heater before mixing and purging
the slurry.
–Close the slide valves when storing slurry outside.
–The fan for the air supply must not be part of a
closed pipe system.
–The space to be heated must be adequately ventilated.
For mechanical extraction equipment: at least
10 m3/h of air per installed capacity.
In the case of natural ventilation, the structure
must have two apertures with a free opening area
of 60 x B in cm2. “B” is the installed capacity in
kW. Replacement of the full air volume per hour
is thus ensured.
–In the case of natural ventilation, the maximum
allowable total capacity of the heater is 1 kW per
20 m3 of volume.
–Respect the safety distance of the heater to inflammable materials, see Installation position.
–Consult your fire insurance provider and/or local
fire protection engineer to assess the foreseeable,
general risk of fire.
–For cleaning, care and maintenance, note the
applicable national regulations and directives.
Installation position
▷▷ To ensure that the vane functions faultlessly, install the unit in the horizontal position.
