Safety Instructions
REMKO electric heaters will provide you with high utility
and long life thanks to our extensive material, function
and quality controls. Dangers may arise nevertheless if
the unit is used by persons not familiar with its operation or if the unit is not used for its intended purpose.
The persons charged with the operation of the units
have to check these before starting work as to visible
defects of the operation and safety devices, as well as
to make sure that no protective devices are missing.
In the case of faults the supervisor is to be informed.
In the case of faults which endanger the safe opera-
tion of the units, the units are to be stopped!
During the operation of the units the applicable local
regulations are to be observed and the relevant
safety measures to be taken.
Make sure that the prescribed safety distances from
combustible objects are observed!
A free air suction and air discharge must be en-
sured.
The blow off opening of the unit may not be narrowed
or equipped with hoses or conduits.
Never place foreign objects into the unit.
Do not cover the units during operation.
The units may not be operated near bath tubs,
showers, swimming pools, etc.
The units may not be operated directly beneath a wall
socket.
The units may not be exposed to direct water jets.
Application
Drying of new buildings, spot heating of working
places outside or in fire-proof halls and production
places.
Permanent or temporary heating of rooms.
Defrosting of machines vehicles and fire-proof stor-
ing goods with keeping the prescribed distance of
safety.
Working of the unit
All units can be used for heating or ventilation by setting
the equivalent mode on the operating switch.
The unit ELT 3-2 has got exclusively on heating stage
and has a 2 step operating switch.
The units ELT 10-6 and ELT 18-9 has got three heating
stages.
The units can be operated with a room thermostat
(accessories) which is ready to be plugged in, to ensure
a constant room temperature. When the pre-selected
temperature has been reached, the thermostat stops
the heating operation to restart it when the temperature
has fallen below the set value.
When the units have been switched off by the operating
switch or the room thermostat, the supply air fan continues running for a certain time to cool down the heat exchanger, and then it stops automatically.
The electric connection of the units is to be carried
out via a special supply point with fault current
safety switch.
Make sure that no water penetrates inside the units.
The units may not be operated in rooms which are
endangered by explosions.
Protect all electric cables outside the units from
damage (e.g. caused by animals).
Connecting cable extensions may be laid exclusively by authorised electricians based on the
unit capacity, cable length and taking the local
terms of use into account.
Description of the Unit
The units are operating with electric energy and are
suitable for a fully automatic, all-purpose and simple application.
The units are equipped with capsuled electrical heating
elements, noiseless maintenance-free axial fans, safety
and after-cooling thermostat, thermostat socket and
connecting cable with plug.
The units are in accordance with the basic safety and
health requirements of the relevant EC – regulation.
The units are handled simply and are safe in operation.
Starting
A well trained person is to be charged with the operation and control of the units.
1. Check the main voltage is in accordance with the
unit voltage.
ELT 3-2 230V/1~
ELT 10-6 and ELT 18-9 400V/3~
2. Put operating switch into
position "0".
3. Connect the unit-plug to an adequate mains socket..

Attention, important hints to the
The air supply fan continues running to cool down the
unit and then stops later.
Fan can start several times before final switching off.
Never interrupt (except in emergency situations)
the connection to the mains before the end of the
whole after-cooling phase.
Our guarantee does not cover damages caused
to the unit by overheating.
Maintenance
Regular maintenance and the observation of some basic principles is important to ensure a long service life
and a trouble-free operation of the unit.
Prior to starting any work make sure to pull the
mains plug out of the mains socket!
Please pay attention to the following points:
after-cooling phase.
For optimum unit operation, the device should not
be operated at an ambient temperature above 25 °C.
Heating with room thermostat
The unit runs fully automatically and is dependent on
set temperatures.
1. Remove the bridge circuit plug 2.
2. Connect thermostat plug 3 of the
room thermostat (accessories) to
the thermostat socket 1.
3. Put room thermostat 4 in a suitable
place.
The thermostat sensor may not be
exposed directly to the hot air current and not fixed directly on a cold
surface.
4. Pre-select desired room temperature on the room thermostat.
5. Put the operating switch into the desired position.

The unit is to be maintained and cleaned in regular
intervals.
The unit is to be kept free from dust and other de-
posits and is to be cleaned only with a dry or humid
cloth.
Do not use water jet.
Do not use any aggressive cleaning agents or those
which are harmful or environmentally unfriendly.
Do not use cleaning agents which contain solvents.
Only use suitable cleaning agents to remove ex-
treme dirt.
Check safety devices regularly.
Check protective suction and blower grids regularly
and clean, when necessary.
Do not damage the sensor and capillary tube of the
thermostat when the protective blower grid is installed or removed.
According to the terms of use the units are to be
checked as to their perfect operation by an expert
when necessary, but at least once a year.
Please carry out an electrical safety test after having finished service on the unit.

Troubleshooting
Prior to starting any work make sure to pull the
mains plug out of the mains socket!
Setting and maintenance is to be carried out
only by authorised experts!
Unit (fan) does not start:
1. Check main fuse
2. Check connecting cable with plug
3. Check operating switch
4. Check slight drifting of fan (motor)
Unit does not heat
1. Check operating switch
2. Check auxiliary relay / contactor
3. Check function of temperature limiter resp. check
capillary tubing (if damaged)
4. Check if thermostat plug resp. bridge circuit plug is
coupled
5. Check thermostat-operation: thermostat must be set
higher than the room temperature
Should the unit still not be working despite these checks,
please contact an authorised service centre.
(ELT 10-6 / ELT 18-9).
