POSITIONING OF THE UNIT
The ambient temperature must not exceed 40°C and ambient humidity should not
exceed 85%. Place the unit in a way that ensures good air circulation. Maintain a

minimum distance of 3 m from each side of the unit. Keep the unit away from any
hot surfaces and flammable materials as well as direct sunlight. Always operate the
unit on a level, stable, clean, fireproof and dry surface and out of the reach of
children and persons of impaired mental, sensory and intellectual functions. Place
the unit in such a way that the mains plug can be reached at any time. Ensure that
the power supply to the unit corresponds to that specified on the identification
plate! Refuel only with the unit turned off.
ASSEMBLY OF THE UNIT
•Insert the axle (H) of the wheels into the holes at the ends of the lower
frame (B), then place the wheels (F) on its ends.
•Then, on the ends of the axle (H) protruding through the holes in the
wheels, put flat washers (G) and secure them with self-locking nuts (E) at
its ends.
•Through the holes in the axles from the inside of the wheels, insert the
safety clips and bend their ends to prevent them from falling out.
•Place the heating unit with the fuel tank on the so-prepared lower frame
(B), making sure that the holes at the ends of the tank are aligned with the
holes in the lower frame.
•Attach the transport handle (A) from above, also making sure that the holes
in it are aligned with the holes at the ends of the tank and the lower frame
(B).

•Insert the screws (J) through all of these holes from the top, and tighten
them firmly from the bottom with nuts (C), so that some of the screws also
hold the handle on each side of the unit.
•This way, the device is ready for use, i.e. the entire heating unit is
permanently connected to the frame base and the transport handle.
•Finally, mount the end of the exhaust outlet on the top.
3.3. Working with the device
3.3.1 Refueling
IMPORTANT: Use only diesel fuel or heating kerosene to power the
unit.
The fuel should be fresh and free from contamination - it is not
recommended to store fuel in an unused device for more than 1-2
months.
For refueling, use a special funnel (not included in the set), which will
help in preventing fuel spilling on and around the device.
Before refueling, the device should be turned off, disconnected from
the power supply and cooled down to minimize the risk of ignition.
•Place the device on a stable, flat and even surface.
•Unscrew the fuel cap - do not remove the mesh filter (it protects
against dirt accidentally entering the fuel system)!
•Insert a special funnel into the opening.

•Refill the fuel tank, paying attention to when the gauge
approaches the "F" position (full tank), then stop refuelling and
tighten the fuel cap.
•Wipe off any spilled or dripped fuel immediately with a dry cloth.
If the unit has cooled down completely, the greasy stains from the
fuel can be removed with a cloth lightly dipped in benzine or
alcohol.
3.3.2 Working with the device
After a general inspection of the device for damage and refilling the
fuel in the tank if necessary, proceed to the following:
•Connect the plug to a suitable power outlet.
•Set the power switch to the on ("I") position.
•Set the desired temperature with the temperature control
knob.
IMPORTANT: If the set temperature is higher than the
ambient temperature in which the device is located, it will
turn on. When the ambient temperature reaches a value
higher than the temperature set on the device, it will
automatically turn off. If the ambient temperature drops
below the set value, the device will restart.
When the temperature set on the device is lower than the
ambient temperature during the first start-up, the device
will not start up until the ambient temperature is lower than
the set temperature.
•Before turning off the unit, set the knob to the lowest
temperature, then set the power switch to the off ("O")
position. When the fan stops, disconnect the plug from the
power supply.
NOTE: if the device works in breaks/bursts flames or does
not heat (despite the fuel being in the tank), adjust the
pressure on the turned-on device by turning the screw
located next to the manometer (see the following 3 pictures)
using, for example, a suitable size screwdriver with a flat tip:
•When the unit bursts flames - counterclockwise until its
operation is stabilized - then leave the screw in this position.
•When the device does not heat up, turn the screw clockwise
until it starts to heat normally - then leave the screw in this
position

When the power switch is lit as usual, it means that the
device is working properly. When it blinks, it indicates a
problem with the device - see more in "Troubleshooting".

IMPORTANT: the device has a built-in protection in the event
of excessive flame, which, for safety reasons, will cut off the
fuel supply and turn off the fan after 90 seconds. In the event
of a power failure, the unit will stop working immediately.
When the power returns, the device will only signal this fact
by lighting up the power supply control, but it will not start
up automatically - for safety reasons, you should restart it
manually.
3.4. Cleaning and maintenance
a) Pull the mains plug and let the unit cool down completely before cleaning,
adjusting or replacing accessories and when the unit is not in use.
•Wait until the rotating parts stop.
b) Use only non-corrosive cleaning agents for cleaning the surfaces.
c) Store the unit in a dry and cool place protected from moisture and direct
sunlight.
d) Do not spray the unit with a stream of water or immerse it in water.
e) Make sure that no water enters through the ventilation openings in the casing.
f) Clean the ventilation openings with a brush and compressed air.
g) Perform regular inspections of the unit checking technical fitness and any
damages.
h) Use a soft cloth for cleaning.
i) Do not use sharp and/or metal objects (e.g. wire brush or metal spatula) for
cleaning as they may damage the surface of the appliance material.
j) Do not store fuel in an unused unit for more than 2 months.
k) In the case of regular use (8-10 hours a day), clean the unit:
•Once a month - the ignition electrodes and the combustion chamber.
•Every six months - the fuel tank.
3.4.1 Draining the fuel tank

In order to empty the fuel from the tank, place a fuel container under the
device near the leg, and place under the wheels some wooden blocks, etc., so
that the device is slightly tilted towards the transport handle (see the picture
above). Then unscrew the drain plug located at the bottom of the tank and
drain the fuel completely. After draining and before refueling, tighten the drain
plug.
3.4.2 Cleaning the electrodes and checking the space between them
1. Motor
2. Fan
3. Ignition electrodes
4. Oil nozzle
5. End of exhaust
6. Combustion chamber

7. Warm air outlet
8. Air circulation chamber
The ignition electrodes are located in the burner head:
To get to them, you need to disassemble, among others, the air inlet grill. Clean
the electrodes with, e.g., benzine using a fine brush. Before reassembly, check
and, if necessary, set a proper distance between them (see technical data
table).
