Description of Device
The units are fired directly with heating oil or diesel.
They are designed for fully-automatic, universal and
reliable use.
The units are equipped at the factory with a large-
volume fuel preheater as well as a heating oil filter
protected from weather conditions. They are operated
with a separate forced-air oil burner and are suitable
for outdoor operation.
The units are equipped both with a high-performance
axial fan that requires little maintenance and inte-
grated switching and regulating units. They also have
an optical display which shows the individual operat-
ing functions.
The units have a sturdy framework design on robust
transport runners.
To ensure that the units can be operated over a pe-
riod of many years, particularly outdoors, the frame-
work and the lining plates are made of rust-proof
stainless-steel. In addition, all of the construction parts
inside the unit are also made of non-corrosive materials.
The compact design of the units makes them easy
and affordable to assemble quickly and guarantees
that they are easy to service.
The unit meets the basic safety and health require-
ments found in the relevant EU regulations and is
easy to operate.
*
The units are not designed for permanent fixed in-
stallation.
Locations for unit operation
The units are direct-fired, warm air heaters that supply in-
stantaneous heat. They are only used for commercial pur-
poses.
The units are used in the industrial area when portable
units are required to heat or regulate the temperature
of, for example:
– Warehouses
– Exhibition spaces
– Trade shows
– Large tents
– Temporary structures for warehousing
– Large construction sites
There are generally no restrictions as to where they can
be used for temporarily heating buildings due to their
weatherproof design.
Functionality
If the unit is switched to heating mode, the forced-air oil
burner switches on automatically. The green “burner“
operating light is illuminated on the control panel for
monitoring purposes. If heating mode is controlled by a
room thermostat, the forced-air oil burner starts only
when heat is required.
Proper Use
These devices have been designed and equipped exclu-
sively to be used for heating and ventilation for industrial
and commercial purposes.
The manufacturer is not liable for any damage resulting
from non-adherence to manufacturer specifications, le-
gal requirements or any modifications to the units.

Safety Mechanisms
Three-speed combination regulator in accordance
with DIN 3440
The unit has 3 functions:
◊ Fan regulator (TR)
◊ Temperature monitor (TW)
◊ Safety temperature limiter (STB)
Fan regulator (TR)
The temperature control thermostat switches the circu-
lation fan on and off. The activation point is set by
means of the adjustment lever.
Target value approx. 35 °C.
Temperature monitor for the burner (TW)
The temperature monitor limits the temperature of the
units and the air being blown out via the burner in heat-
ing mode. The activation point is set using the adjust-
ment screw on the target value spindle.
Target value approx. 85°C.
Safety temperature limiter (STB)
The STB controls the temperature monitor. There is a
button that, when pressed, prevents the burner from the
restarting. The reset button on the control box must be
pressed
The activation point is fixed in accordance with DIN
3440.
Information about the safety mechanisms
The sensors of the safety mechanisms are self-
monitoring and can work at cold temperatures of down
to -20 °C. At temperatures below 20 °C, they switch off
and when the temperature rises, they switch back on
again.
When the sensor or capillary tube is damaged, or when
an excess temperature of approximately 220°C is
reached, the liquid contained in the thermostat is emp-
tied and the safety mechanism switches the unit off.
The temperature control thermostat is no longer oper-
able and must be replaced.
If the three-speed combination regulator needs to be re-
placed, only use the original REMKO-spare part ref. no.
1102562.
Make sure to observe the following:
◊ Make absolutely sure that the units are carefully in-
stalled and assembled.
◊ Do not bend the capillary tubes close to solder
points.
◊ When installing the capillary tubes, be careful not to
damage or bend them too sharply.
◊ The sensors may only be mounted at the attachment
points created for this purpose at the factory.
◊ The sensors must always be kept free of dirt and
dust.
The combustion chamber with heat-exchanger is
heated up until the temperature monitor switches on
(target temperature of 80 to 85 °C). The temperature
regulator (target temperature 35 to 40 °C) automatically
switches the air supply fan on beforehand. The green
“fan“ operating light is illuminated on the control panel
for monitoring purposes. Warm air is blown out.
When the room thermostat is in operation, the process
above is automatically repeated depending on the
amount of heat required .
After the device is switched off with the operating switch
or the room thermostat, the air supply fan runs for a cer-
tain amount of time to cool the combustion chamber with
heat-exchanger and then switches off. This process can
be repeated several times.
Monitoring Unit Operation
All functions of the device are her carried out fully auto-
matically and monitored for safety by the three-speed
combination regulator and the automatic burner relay
(part of the forced-air oil burner).
If the flame burns irregularly or goes out, the unit is
switched off by the automatic burner relay. The control
lamp on the control panel and the red malfunction lamp
“Burner” light up.
The unit may only be restarted after the automatic
burner relay has been manually released by pressing
the “Burner” reset button on the control box.
The temperature control thermostat (TR) regulates op-
eration of the fan. The temperature monitor (TW) limits
the temperature of the air blown out of the unit in heat-
ing mode via the forced-air oil burner.
The safety temperature limiter (STB) interrupts opera-
tion of the unit or burner when extreme overheating oc-
curs or if the TW stops working or is defective. The red
malfunction light “Overheating” is illuminated on the
control panel.
The STB is released by pressing the “Overheating” but-
ton on the control panel. The STB can only be manually
released after the unit has cooled.
The fan motor is monitored by a thermal overcurrent re-
lay. If the capacity of the motor is overloaded, operation
is interrupted by the relay and the red malfunction light
“Fan” is illuminated on the control panel.
All electrical components are also protected by safety
mechanisms. They can only be reset once the control
box has been opened. Prior to opening the control box,
the unit must be unplugged from the power supply.
Prior to resetting the unit, the causes of the malfunction
must be identified.
*
Before releasing the safety temperature limiter
(STB), the possible causes of the malfunction
must be identified.

Unit Assembly
When setting up the units, the relevant regional building
and fire protection codes of the respective region must
be observed.
When selecting an indoor or outdoor location to set up
the units, the settings must be adjusted with respect to:
◊ Fire protection and operating hazards
◊ Maintenance of adequate safety zones
◊ Function
Room heating, free-standing or canal system, ex-
cessive or low pressure in the setup room.
◊ General requirements
Heating needs, room temperature, rated air output,
air distribution, need for circulation or outside air,
space needs, etc.
◊ Exhaust system
◊ Assembly, repair and servicing options
◊ Indoor setup
Ratio of room volume to rated air capacity especially
for naturally ventilated rooms.
Setup
◊ The units must be placed firmly on a suitable, non-
flammable surface outside of traffic zones, for exam-
ple, away from cranes.
◊ If the surface is soft, appropriate substructures must
be set up such as scantlings below the transport,
runners.
◊ When doing work on the units, make sure that the
units are current-free and set up horizontally.
◊ The units must be set up and operated in such a
way that people are not exposed to exhaust or radi-
ant heat and fires cannot occur.
◊ The units must be set up in such a way that they do
not cause any hazards or unreasonable annoy-
ances.
Tremors, vibrations or noise.
◊ The units must be set up and installed in such a way
that they are easily accessible for repair and mainte-
nance work.
◊ Operating elements which can result in dangerous
operating conditions when used improperly must be
protected from unauthorised .
◊ The units may not be set up or operated in rooms or
areas susceptible to fire or explosions.
◊ The unit may only be set up and operated in rooms if
there is an adequate supply of air for combustion
and the exhaust is expelled via exhaust flues.
◊ A natural air supply sufficient for combustion exists
when, for example,
- the room content in m³ is equivalent to at least 10
times the rated heat output in kW of all heating
units in operation in the room and natural air venti-
lation is supplied through windows and doors.
◊ Good natural ventilation exists when, for example,
- the room content in m³ equals 30 times the rated
heat output of all units in operation in the room
and natural ventilation is supplied through doors
and windows .
Expulsion of exhaust
When the units are operated outside or in open rooms
you do not need an exhaust system.
However, to safely expel exhaust, an exhaust pipe 1 m
long with a rain cover (accessory) should be attached to
protect people and keep rain from getting into the com-
bustion chamber.
For indoor setup (closed rooms) an appropriate exhaust
system that meets the valid regulations is required.
Important information about longer exhaust lines
To prevent damage to the combustion chamber caused
by moisture build-up (condensation) for longer exhaust
lines, make sure that the exhaust gas pipe has a prop-
erly installed condensation trap.
Fuel supply
The customer must ensure that certified safety tanks
provide an adequate fuel supply.
◊ You must observe any additional regulations of the
respective regional building codes as well as the
technical regulations for combustible liquids “TRBF
210 and 280".
◊ Particularly for heating oil lines, make sure that the
cross-section of the lines corresponds to the suction
height, the total line resistance and increased vis-
cosity at lower temperatures. If necessary, it is pos-
sible to connect an oil transport device.
◊ The suction line must be equipped with a valve at
the end of the hose in the tank.
◊ To ensure that operation in heating mode is as
smooth as possible, there must be an adequate
quantity of heating oil available that can flow even at
low outdoor temperatures. Appropriate measures,
for example, the use of a tank heater, must be un-
dertaken to ensure that boil can flow freely.
*
Paraffin can accumulate at temperatures starting
at approximately 5 °C!

Circulation
Circulation mode
A pipe adapter (accessory) on the suction side is
necessary for pure circulation mode.
◊ Air lines her hold their shape must be placed on the
intake side.
Do not use unstable lines.
◊ When setting up the unit outside, a folded spiral-
seam pipe or similar device should be used for
circulation.
Fresh air mode
Air is taken in at the back of the units (factory made).
Schematic diagram (example)

Fresh air
Electrical connection
◊ The units are operated with 400/3~N/50.
◊ The unit must be connected to the power source at a
special terminal equipped with a switch to protect
against faulty currents in accordance with VDE 0100
§ 55.
◊ The design of the connection cable depends on the
unit’s electrical capacity and the length of the cable
and takes into account the local conditions.
◊ Extension cords may only be used if they are com-
pletely unrolled or rolled up.
Warm air distribution
The units are equipped with a high-performance axial
fan that requires little maintenance. This fan has been
designed, depending on the requirements, to direct the
warm air efficiently.
It is preferable to distribute air by means of pipes or
special hot air and plastic hoses. The possible lengths
of these lines depend on the air-side resistance of the
warm air ducting.
Make sure to observe the following when using warm
air hoses:
◊ Use only warm air hoses (accessories) approved by
our company.
◊ The inner overlappings of the seams of the warm air
hoses must point in the direction of the air.
◊ Make sure that the hoses and/or pipes are securely
attached to the unit’s air outlet connection.
◊ To prevent heat from building up, the pipes and
hoses may not have sharp kinks and bends.
◊ We recommend using folded spiral-seam pipes.
◊ Use warm air or plastic hoses only for straight air
lines if possible.
◊ Plastic hoses may not be twisted.
◊ When heating closed rooms via warm air lines, no
counter pressure may not build up.
◊ If the suction temperatures or resistance on the unit
outlet increases, the forced-air oil burner can be
switched off in heating mode temporarily by the tem-
perature monitor (TW).
Once the temperature has fallen, the burner
switches are again automatically.
◊ If the intervals are too short, the length of the warm
air line should be checked.
*
Avoid starting the forced-air oil burner in frequent
cycles (under 5 min.).
*
If blockages cause the unit to heat up, heating op-
eration is permanently interrupted by the STB!
Operating modes
The units can be used in the fresh air and circulation
modes.

7. Check whether the green control lights for phases
and control phase are lit up on the control box.
8. Open all shut-off mechanisms of the fuel supply.
9. Set the operating switch on the control box to
“I” (heating).
10.Remember that the forced-air oil burner does not
switch on immediately when heat is required, the air
supply fan only switches on once the target tem-
perature has been reached.
11.Check whether the operating lights for the burner
and fan are lit up on the control box.
12.Close the door.
13.Lock the door to protect the unit from unauthorised
operation.
Operating mode
The unit operates fully automatically according to the
pre-selected room temperature.
If the suction temperatures or resistance on the unit
output increased, the burner can be temporarily
switched off during heating mode by the temperature
monitor (TW).
After the temperature has fallen, the burner automati-
cally starts again. You should avoid starting the burner
frequently during unit operation.
If the temperature increases too much on the air outlet,
the STB interrupts heating mode permanently!
Prior to Operation
Prior to initial operation, check the unit for any visual
defects on the control and safety mechanisms, make
sure that it has been installed correctly and that it has
been properly connected to the power supply.
The exhaust values of the forced-air oil burner must be
checked and adjusted by authorised personnel in line
with the respective on-site conditions.
After installation of the complete air distribution system,
the following checks should be performed by trained
personnel to ensure that the fan always runs properly!
Measuring the rated power and power consumption
1. For correct measurement, attach all pipes to the out-
let and intake sides and open any outlet grilles.
2. Check the available power supply.
3. Make sure that the rated current (amperes) specified
on the motor type plate is not be exceeded.
Setting the thermal overcurrent relay
1. Measure each phase separately to eliminate meas-
urement errors.
2. Set the thermal overcurrent relay according to the
following calculation:
Multiply the rated current of the drive motor by 0.58
and adjust the thermal overcurrent relay to the cal-
culated value.
3. Check the function of the overcurrent relay and its
set value by simulating a missing phase.
By switching off a fuse, etc.
4. Keep in mind that if the relay is functioning and set
properly, it will start after approximately 30 seconds.
Caution, important information about the overcur-
rent relay!
The thermal overcurrent relay may only be operated
when set to “Manual Reset”. The relay may not be
switched back on again automatically after cooling.
Power consumption too high
If the motor is consuming too much power despite hav-
ing a proper electrical connection and adequate power
supply, the thermal overcurrent relay may not be set
higher or bypassed under any circumstances.
◊ Take appropriate measures to fix the problem, e.g.
by checking or adjusting the diameter of the intake
and outlet on the air side.
*
If the overcurrent relay is operated in “Automatic
Reset” mode, it is possible that the motor will be
damaged. We assume no liability for the guaran-
tee!

of the nozzle.
Proceed as follows:
1. Hold the assembly base plate horizontally.
2. Slide the right mount sideways into the suspension.
3. Suspend the left side up into the lug..
All dimensions are approximate values in mm. The opti-
mum setting must be adjusted to the local and struc-
tural conditions.
Adjusting the ignition electrode and swivel disc
3 5
7 – 8
After the nozzle has been changed and the air intake
nozzle adjusted, the assembly base plate is reinserted
in the reverse order.
Adjusting the air intake nozzle
The necessary burner pressure can be adjusted with-
out changing the outlet diameter using the adjustable
air intake nozzle depending on the combustion cham-
ber resistance and chimney draft.
Loosen the Allen screw and ro-
tate the air intake nozzle to the
desired position (pay attention to
the arrow).
“min” = lower burner
pressure
“max”= higher burner
pressure
Adjusting the secondary air
(nozzle connection rod setting)
Left rotation (+) = higher scale value
Ölower pressure behind the swivel disc
Öhigher performance range.
Right rotation (-) = lower scale value
Öhigher pressure behind the swivel disc
Ölower performance range.
Adjusting the pump pressure
The oil pressure must be adjusted and/or checked prior
to operation and maintenance.
Do not run the pump without oil!
1. Remove the plug on the “P” measuring connection.
Pay attention to the seal.
2. Open all oil shut-off mechanisms and switch the
burner on with the unit operating switch.
3. Adjust the necessary oil pressure in accordance with
the nozzle size and the unit capacity.
4. Remember that the required oil pressure first has to
be set for the full capacity phase (DV2) and then the
oil pressure for the start-up phase (DV1) because
the pressure adjustment DV2 can also affect DV1.
5. Switch the burner off on the unit operating switch.
6. Disassemble the manometer and reinsert the plugs
with seals.
*
The burner may only be operated at the second
level. The first level may only be used as start-up
relief!

Adjusting the air flap
The air flap is opened or closed until the soot pattern
displays an oil-free colour, soot “0 - 1” and value 12-14
% for the CO2. When making the adjustment, keep in
mind that when there is a lot of excess air, the soot in-
creases again and oil can reappear in the soot pattern.
If, when the air flap is completely open, the flame emits
soot or does not burn evenly, the pressure behind the
swivel disc must be reduced with the adjustment screw.
Adjustment motor function
The adjustment motor has three set positions as well as
an activation contact for the “Magnetic valve level 2”.
Blue cam Level 1
Orange cam Level 2
Black cam magnetic valve Level 2
Opening scale
Opening indicator
Setting “Air quantity level 1”
(adjustment lever blue)
Unplug the 4-pin multi-purpose connection.
Thermostat level 2.
Turn the orange adjustment lever “Air quantity Level 2”
and the black adjustment lever “Magnetic valve 2”
clockwise until both activation cams are initially not
pressed down so that the setting the activation cam for
the “Air quantity 1” is not blocked.
Less air Level 1:
Set the blue adjustment lever counter-clockwise to
the smaller opening angle. When the burner is run-
ning, the adjustment motor automatically adjusts.
More air Level 1:
Set the blue adjustment lever clockwise to the larger
opening angle. When the burner is running, the ad-
justment motor automatically adjusts.
Activation point “Magnetic valve 2”
(adjustment lever black)
The adjustment lever for “Magnetic valve 2” is now ro-
tated back counter-clockwise and the activation point
“Air quantity 2” is placed briefly behind the “Air quantity
1” activation point. This activation point works between
the positions “Air quantity Level 1” and “Air quantity
Level 2”.
Important information
Please make sure that the activation cam from “Magnetic
valve 2” is not pressed before activation cam “Air quan-
tity level 1” because otherwise the “Magnetic valve 2” in
the “Air quantity 1” area opens and the burner would
run with an insufficient quantity of air.
Setting “Air quantity level 2”
(adjustment lever orange)
Turn back the adjustment lever for the “Air quantity level
2” counter-clockwise. Determine the activation point for
the “Air quantity level 2” based on the burner capacity
behind the activation point “Magnetic valve 2”. Plug in
the 4-pin multi-purpose connection of thermostat level 2
again.
Less air Level 2:
Set the orange adjustment lever counter-clockwise
to the smaller opening angle. Switch to the burner
briefly back to Level 1.
After the unit is switched back to Level 2, the adjust-
ment motor’s speed adjusts to the changed quantity
of air.
More air Level 2:
Set the orange adjustment lever clockwise to the
larger opening angle. When operating at Level 2, the
speed of the adjustment motor adjusts automatically.
*
Make sure that there are no mechanical defects on
the adjustment motor or the air flap otherwise the
adjustment motor will be damaged.
Air flap closed
If the burner is not in operation,
the adjustment motor is set to air
flap closed (scale: 0).
This position (rear cam without
adjustment lever) is set at the fac-
tory and may not be changed.
Air quantity “Level 1”
For pre-ventilation, starting and
operation at a “lower” perform-
ance, the adjustment motor ro-
tates to the activation point of the
blue adjustment lever.
This results in a fixed opening an-
gle for the air flap and a constant
quantity of air for the first level.
This adjustment lever can be
used to regulate air quantity
“Level 1” for different air quanti-
ties ; standard value: approx. 30°.
Activation point “Magnetic valve 2“
The black adjustment lever
“Magnetic valve 2” should be
placed a third of the way between
the blue and orange levers.
Air quantity “Level 2”
If the burner is released for the
second level, the adjustment mo-
tor rotates to the activation point
of the orange lever.
While rotating, the black lever
releases the oil quantity for the
second level; standard value:
approx. 50°.
