6.1 Air supply

ƒ To protect the unit and heating element, do not fail
to meet the minimum air volume and do not exceed
the maximum supply air temperature (see technical
data). If the minimum air volume is no longer
present, then the heating output must be interrupted
at once.
ƒ Note the flow direction.
ƒ The maximum air pressure must never be exceeded
in the compressed air connection (see technical data).
ƒ Use an air filter if there is dusty air. In cases of
particularly critical dusts (e.g. metal, electrically con-
ductive or moist dusts), special filters must be used in
order to avoid short circuits in the device.

ƒ At the end of each unit use, turn off the heating.
ƒ After turning off the heater, hold the air supply for a few minutes to cool the unit.
