1 Safety and
usage instructions
1.1 General safety notes
Carefully read the operating manual before com-
missioning the units for the first time. It contains
useful tips and notes such as hazard warnings to
prevent personal injury and material damage.
Failure to follow the directions in this manual not
only presents a danger to people, the environment
and the system itself, but will void any claims for
liability.
Keep this operating manual and the refrigerant
data sheet near to the units.
1.2 Identification of notes
This section provides an overview of all important
safety aspects for proper protection of people and
safe and fault-free operation.The instructions and
safety notes contained within this manual must be
observed in order to prevent accidents, personal
injury and material damage.
Notes attached directly to the units must be
observed in their entirety and be kept in a fully
legible condition.
Safety notes in this manual are indicated by sym-
bols. Safety notes are introduced with signal words
which help to highlight the magnitude of the danger
in question.

Contact with live parts poses an immediate
danger of death due to electric shock. Damage
to the insulation or individual components may
pose a danger of death.
DANGER!
This combination of symbol and signal word
warns of a situation in which there is immediate
danger, which if not avoided may be fatal or
cause serious injury.
WARNING!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may be fatal or cause
serious injury.
CAUTION!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may cause injury or mate-
rial and environmental damage.
NOTICE!
This combination of symbol and signal word
warns of a potentially hazardous situation,
which if not avoided may cause material and
environmental damage.
This symbol highlights useful tips and recom-
mendations as well as information for efficient
and fault-free operation.
1.3 Personnel qualifications
Personnel responsible for commissioning, opera-
tion, maintenance, inspection and installation must
be able to demonstrate that they hold a qualifica-
tion which proves their ability to undertake the

3 Unit description
The units are portable electric heating units for
industrial applications.
The units are operated exclusively with electric
power and have been designed in such a way that
they can be used fully automatically, universally
and in a straightforward manner.
The units are equipped with specially enclosed
electric heating resistors, low noise and low-main-
tenance axial fans, a safety and aftercooler ther-
mostat, an integrated room thermostat and a
power cable with protective contact plug.
The units conform to the fundamental health and
safety requirements of the appropriate EU regula-
tions.
The units are dependable and offer ease of opera-
tion.
The units may be used among other things for the
following:
nDrying newly completed buildings
nSpot heating outdoor workspaces or fire-proof
manufacturing facilities and halls
nContinuous or temporary room heating
nDe-icing machines, vehicles and non-combus-
tible warehoused goods while adhering to the
relevant safety distances
Operating sequence
The units can be used in the respective operating
modes for air heating and air circulation purposes
(only EM 2000).
The units have a 3-stage operating switch with the
functions:
EM 2000: Heating (I) / OFF (0) / Ventilation (II)
EM 3000: Heating 2.2 kW (I) / OFF (0) /
Heating 3.2 kW (II)
In the heating settings, the heating resistor or
heating resistors of the EM 3000 and the fan are
switched on. Warm air is blown out.
The unit is equipped with an integrated thermostat
to ensure that the room temperature is constant.
Once the selected temperature has been reached,
the thermostat stops the heating operation. If the
room temperature falls below the selected temper-
ature, the thermostat starts up the heating opera-
tion again.
The integrated thermal cutout switches off the unit
if the temperature is excessively high and switches
it on again automatically after it has cooled down.
EM 2000: In setting II (Fan), only the air circulating
fan is switched on and the unit can only be used
for air circulation.
