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
work.
1.4 Dangers of failure to observe

to people, the environment and the units. Failure to
observe the safety notes may void any claims for
damages.
In particular, failure to observe the safety notes
may pose the following risks:
nThe failure of important unit functions.
nThe failure of prescribed methods of mainte-
nance and repair.
nDanger to people on account of electrical and
mechanical effects.
1.5 Safety-conscious working
The safety notes contained in this manual, the
existing national regulations concerning accident
prevention as well as any internal company
working, operating and safety regulations must be
observed.

ator
The operational safety of the units and compo-
nents is only assured providing they are used as
intended and in a fully assembled state.
nThe personnel tasked with operating the units
must check the units for visible defects on the
operating and safety devices as well as the
presence and function of the protective devices
prior to starting work.
If defects are discovered these must be
reported to the supervisor!
nIn the event of defects that endanger the
operational safety of the unit, operation must
be discontinued immediately.
nDo not operate units or components with
obvious defects or signs of damage.

1.9 Intended use
The units are designed exclusively for heating and
ventilation purposes in industrial or commercial use
(no living space heating in private use) on the
basis of their structural design and equipment. The
units must only be operated by appropriately
instructed personnel.
Any different or additional use is a non-intended
use. The manufacturer/supplier assumes no lia-
bility for damages arising from a non-intended use.
The user bears the sole risk in such cases.
Intended use also includes working in accordance
with the operating and installation instructions and
complying with the maintenance requirements.
The threshold values specified in the technical
data must not be exceeded.
1.10 Warranty

3 Design and function
3.1 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, a low noise and low-
maintenance radial fan, a safety and aftercooler
thermostat, 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.
Locations at which units are used
The units are designed exclusively for commercial
use.
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 modes for
air heating and air circulation purposes.
They can be operated on three heating settings
and one fan setting. They have a 5-stage operating
switch with the functions:
Off (0)
Ventilation (1)
Heating (2-4)
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 cut-out switches off the unit
if the temperature is excessively high and switches
it on again automatically after it has cooled down.
After switching off the units via the operating
switch or the room thermostats, the supply air
fan runs to cool the heating resistors for a cer-
tain time and then switches off automatically.
For optimum operation the units should not be
operated above an ambient temperature of
25 °C.

5 Commissioning the unit
One person, who has been adequately trained in
the handling of the unit, should be tasked with the
operation and monitoring of the unit.
The units must be in the intended horizontal posi-
tion at all times during operation.
The units are equipped with the following operating
switches:
Fig. 2: Operating switch
0: Off
1: Ventilation
2: 1. Heating stage
3: 2. Heating stage
4: 3. Heating stage
1. Check the mains voltage (400V/3~N/50Hz)
and for sufficient fuse protection (64A).
2. Switch the operating switch to the "0" (off)
position.
3. Connect the unit's power plug to a properly
installed mains socket.
The electrical connection for the units must be
made at a separate feedpoint with a residual
current device in accordance with VDE 0100,
Section 55.
NOTICE!
Extensions to the connection cable must only
be conducted by authorised specialist electri-
cians, taking into consideration the unit power
consumption, cable length and local use.
Operating mode settings
The operating mode settings can be selected using
a rotary selector switch.
However, a room thermostat is always required for
operation.

Ventilation
Only the supply air fan operates in this setting.
Thermostatic regulation and heating operation are
not possible in this operating mode.
Switch the operating switch to the corresponding
position 1.
Fig. 4: Ventilation switch position
Heating with room thermostat (accessory)
The units operate fully automatically and according
to the room temperature.
1. Pull out the strapping plug [2].
2. Connect the room thermostat [4] plug [3] with
the thermostat receptacle [1] on the unit.
3
1
3. Place the room thermostat [4] at a suitable
location in the room. The thermostat sensor
must not be located directly in the warm air
flow and must not be placed directly on a
cold floor.
4. Set the desired temperature on the room
thermostat [4].
4
5. Select the desired power position on the
operating switch.
6 Shutdown
1. Switch the operating switch to the "0" (off)
position.
The supply air fan runs on to cool the units
and only switches off after the cooling down
phase is complete. The fan can switch on
and run several times before the final shut-
down.
2. If shut down for an extended period, discon-
nect the units from the mains power supply.
NOTICE!
Never interrupt the mains connection prior to
the completion of the follow-up cooling phase.
There is no warranty claim for damage to the
units from overheating.
