Safety notes 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-
maintenance axial fans, safety and
aftercooler thermostats, a room
thermostat socket and power cable
with protective contact plug.
The units conform to the
fundamental health and safety
requirements of the appropriate
EU stipulations.
The units are dependable and offer
ease of operation.
The units may be used among
other things for the following:
■ Drying newly completed
buildings
■ Spot heating outdoor
workspaces or fire-proof
manufacturing facilities and
halls
■ Continuous or temporary room
heating
■ De-icing machines, vehicles and
non-combustible warehoused
goods while adhering to the
relevant safety distances
Always observe the respective local building code and fire prevention
guidelines as well as the guidelines of the accident prevention and
insurance associations when using the units.
The units have been subjected
to extensive material, functional
and quality inspections prior to
delivery. However, dangers can
arise from the units if they are used
improperly or not as intended by
untrained personnel!
Please observe the following notes:
■
The 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
Inform the supervisor if defects
are discovered!
■
In the event of defects that
endanger the operational safety
of the unit, operation must be
discontinued immediately
■
Observe the respective local
regulations and the relevant
electrical safety measures when
using the units
■
Maintain safety distances to
combustible materials
■
An unobstructed air inlet and air
outlet must be guaranteed at all
times
■

Operating sequence
The units can be used in the
respective operating modes for
air heating and air circulation
purposes (not ELT 3-2).
The units ELT 3-2 can be operated
exclusively in 2 heating stages
(2.2 or 3.2 kW).
They have a 3-stage operating
switch with the functions: Heat (I)
/ Off (0) / Heat (II).
The units ELT 10-6 and ELT 18-9
can be operated with three heating
settings and one fan setting.
They have a 5-stage operating
switch with the functions:
Off (0) / Fan (1) / Heat (2-4).
All units can be equipped with
a plug-in ready room thermostat
(accessory) to ensure that the
room temperature is constant.
Once the desired temperature
has been reached, the thermostat
switches the heating operation
off. If the room temperature falls
below the set temperature, the
thermostat starts up the heating
operation again.

NOTE
For optimum operation the
units should not be operated
above an ambient temperature
of 25 °C.
NOTE
The electrical connection for
the units must be made at
a separate feed point with
a residual current device in
accordance with VDE 0100,
Section 55.
CAUTION
Extensions to the connection
cable must only be conducted
by authorised specialist
electricians, taking into
consideration the unit capacity,
cable length and local use.

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 certain
time and then switches off
automatically.
CAUTION
!
1. Check the customer’s mains
voltage and ensure sufficient
fuse protection for the unit type
in use.
Power supplies:
ELT 3-2 230V/1~/50 Hz

2. Connect the plug [3] of the
room thermostat [4] with the
thermostat socket [1] on the
unit.
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 the cold floor.
4. Set the desired room
temperature on the room
thermostat [4].
5. Select the desired power
position on the respective
operating switch.
Operating settings
The operating settings can be
selected via a switch or a cam
switch.
