Appliance-specific safety instructions

WARNINGS
IMPORTANT: Please read carefully the complete Operating Instructions before assembling, handling and maintaining this heating unit. Any unauthorised use of this heating unit may result in serious injuries or death as a result of burn, fire, explosion, electric shock and carbon monoxide poisoning.
! CAUTION: Carbon monoxide poisoning may be fatal!
Carbon monoxide poisoning: Early symptoms of carbon monoxide poisoning are similar to those experienced at flu, i.e. headache, giddiness and/or indisposition. If such symptoms are experienced, it may be possible your heating body is not working properly. Get out immediately! Have your heating unit inspected. Some
persons are more sensitive to carbon monoxide than other ones, e.g. pregnant women, persons with cardiac or pulmonary diseases or anaemia, persons under the influence of alcohol and persons at heights. Make sure you have read all the maintenance instructions and have understood them. Keep these Operating Instructions for future reference. They are your guide for safe and professional handling of this heating unit.
- Use only oil to prevent fire and risk of explosion. Petrol, crude oil, paint thinners, alcohol and other highly flammable fuels must not be used in any case.
Fuel:
a) Staff providing refuelling must be trained and fully familiarised with the manufacturer's instructions and applicable directives for safe refuelling of heating units.
b) Only oil may be used for refuelling.
c) Any flame including the pilot flame must be blown out to allow the heating unit to cool down before refuelling.
d) Fuel lines and connections must be checked for leaking when refuelling takes place. Any leaking must be repaired before putting the heating unit back into operation.
e) The maximum fuel daily dose should only be stored in buildings near the heating unit. Large fuel reserves to be stored outside the building.
f) All fuel storages must be at least 762 cm from heating units, burners, welders and similar inflammable sources (exception being a fuel tank integrated in the heating unit).
g) If applicable, fuel storage should only be limited to spaces where the flooring design prevents leaked fuel accumulation and the fuel cannot catch fire as a result of deeply stored inflammable sources.
h) Fuel must be stored in accordance with the local official regulations.
General information:
- Never use the heating unit near petrol, paint thinners or other easily combustible fumes.
- Follow all local provisions and regulations when using this heating unit.
- Heating units used near reinforcement grids, canvases or other coverings must be placed in a safe distance from these materials. The recommended minimum distance is 305 cm. Moreover, using fireproof coverings is recommended. Fireproof coverings must be safely attached to be protected against catching fire and prevent heating unit being touched and turned over due to wind gust.
- To be used in well ventilated spaces only. Before putting the appliance into operation, make sure air vent of at least 2,800 cm ^2 for fresh external air is provided for heating output of 100,000 BTU per hour.
- To be used in spaces with no flammable vapours or high dust levels only.
- To be used at voltage and frequency specified on the type label only.
- A properly earthed extension cable with a three-pin plug to be used at all times.
-
Minimum distance from flammable materials and persons: exhaust: 300 cm at sides, upper and rear side: 200 cm. (see pic. D)
-
To prevent a risk of fire, the hot heating unit or heating unit just being operated must be placed on a safe and level surface.
- The heating unit must be transferred or stored in a horizontal position to prevent fuel leaking.
- Keep children and pets in a sufficient distance from the heating unit.
- Unplug the heating unit if not being operated.
- Never use the heating unit in residential rooms and sleeping rooms.
- Never block the air inlet (rear side) and air outlet (front side) of the heating unit.
- If the heating unit is hot, being operated or plugged, it must never be transferred, handled, refuelled or maintained.

CAUTION:
Oil to be used only to prevent fire or explosion.

Using the appliance as a heat source for events parties or operating the appliance in stables is tly prohibited!
Use as designated
The GD-series oil hot-air turbine must solely be used for heating and drying purposes in well ventilated spaces or dry outdoor zones, in a safe distance from flammable materials and other animals. It must be placed on a stable and level surface when being operated. Only oil is allowed to be used for refuelling.
(As far as safety, functionality and service life are concerned, the GD series follows the latest criteria: the safety equipment guarantees appropriate working of the appliance; operating noise have been reduced to minimum levels and the careful material selection makes it as much reliable as possible.)

These models are supplied with wheels and handles. Wheels, handles and appropriate parts for attaching are in the box.
Necessary tools:
- medium-sized cross screw driver
- CH 8" fork wrench or adjustment wrench
-
hammer.
-
Put the axis through the wheel support frame. Mount the wheels to the axis. IMPORTANT: When assembling the wheels, the extended wheel hub must point towards the wheel support frame (see picture 3).
-
Put a cap nut on each axis end and tighten it by light hammer tapping.
-
Fit the heating unit on the wheel support frame. Make sure the heating unit air inlet (rear) is above the wheels. Attach the fuel tank flange holes to the wheel support frame holes.
- Put the front and rear handle on the fuel tank flange. Pull the screws through the handles, fuel tank flange and wheel support frame. After the screw is inserted, tighten the appropriate nut with your hand.
- Tighten the nuts after all screws have been inserted.
Safety equipment
The oil hot-air turbine is fitted with an electronic flame control. The appliance is stopped in case of operating failure. If the oil hot-air turbine is overheated, thermostat preventing overheating is activated, which interrupts the fuel supply; the thermostat is automatically deactivated if the combustion chamber temperature drops below the accepted maximum value. The overheating cause must be identified and removed (e.g. air inlet and outlet blocking or fan stopping) before putting the oil hot-air turbine back into operation. To start the appliance again, please follow the instructions included under "PUTTING THE APPLIANCE INTO OPERATION".
Putting the appliance into operation
Before putting the oil hot-air turbine into operation and plugging it in, it is necessary to check whether the power supply properties correspond to the values on the type label.
CAUTION:
A safety switch against stray current (RCD) must be integrated in the circuit to which the oil hot-air turbine is connected.
All safety measures regarding ventilation, etc. must be adhered to.
Do not add crude oil to the fuel tank. Close the fuel tank lid again.
Plug the heating unit feeder cable in a standard socket with earth contact.
The following must be provided to put the appliance into operation:
Turn the ON/OFF switch to the ON position: the fan will start and cause ignition after a couple of seconds.
Ignition may take a few seconds when the appliance is started for the first time or after it has not been used for a long time.
The following must be provided to switch the appliance off:
Turn the ON/OFF switch to the OFF position.
