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 blow off must be ensured.
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.
◊
◊ 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 authorized electricians based on the unit
!
capacity, cable length and taking the local terms of
use into account.
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 storing
goods with keeping the prescribed distance of safety.
Working of device
The units are equipped with a 4-stage operating switch.
In the first stage only the supply air fan is operated and
the units can be used for air circulation.
In the 2nd – 4th. stage the heating elements are activated and hot air is discharged.
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.
Starting
A well trained person is to be charged with the operation and control of the units.
The electric connection of the units is to be carried
out via a special supply point with fault current
!
safety switch.
Description of Device
The units are operating with electric energy. They are specially designed for the usage of hot air hoses and 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.

Our guarantee does not cover damages caused
to the unit by overheating.
Maintenance and Service
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

Heating with room thermostat
The unit runs fully automatically and is dependent on
set temperatures.
1. Remove the bridge circuit plug 2.
2. Plug thermostat plug 3 of the room
thermostat (accessories) into 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 operating switch into desired
position (2 or 3 or 4) depending on
the desired heating capacity.
If the temperature at the blower aperture rises
!
above 100° C the heating operation is stopped.

Please pay attention to the following points:
◊ 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.

Hot air distribution
The unit is equipped with a high efficiency axial fan.
The high efficiency axial fan permits operation with hot
air hoses in different variants to transport the warmed
air exactly and efficiently to the specific place.
Please observe the following instructions when hot air
hoses are to be fitted:
Please use exclusively those hot air hoses (acces-
◊
sories) which have been approved by our company.
◊ The internal overlapping at the seams must to point
at air direction.
◊ Make sure that the hot air hoses are safely fastened
to the outgoing air connection piece.
◊ The pipes and hoses may not have sharp kinks and
bends in order to avoid heat accumulation.
◊ If the temperature at the blower aperture rises above
100° C the heating operation is stopped.
A free air blow off must be ensured.
◊
Due to the special high efficiency axial fan, the unit
!
should not be operated without hot air hoses.
