OPERATING CONDITIONS

KEROSENE AND DIESEL FUEL USAGE
These AB heaters are factory adjusted to give the most efficient burn on kerosene but will also burn diesel. Note that kerosene will tend to burn more cleanly than diesel. Care should be taken to provide at least the minimum amount of ventilation recommended when burning diesel.

STORAGE OF FUEL
Always store kerosene and diesel in a well ventilated area well away from general living space. Do not store in direct sunlight
or near a source of heat or other source of ignition such as a torch or a portable generator. Do not use fuel that has been stored from one season to the next as it may have deteriorated and will not burn properly in the heater. Store the fuel in a suitable container which complies with requirements set out in local authority regulations.

WARNING! Air contaminants taken into the heater may affect the heat output, damage the unit and may cause health problems. Example: Bodyshop filler dust / paint overspray will damage the motor bearing, clog the filter and pump and contaminate the combustion chamber causing flame flutter and health hazards. Please note that any parts damaged by filler dust / paint overspray will not be covered by warranty. Additionally, a cleaning charge will be made for any heaters damaged by filler dust.

OPERATION

(REFER TO FIG.1A)

STARTUP

• Fill tank with clean fuel. Only use Diesel or Kerosene.
• The fuel gauge on top of the tank allows to check fuel level.
• Connect the power cord plug to an AC220-240V 50 Hz earthed electrical supply system. Earthing is mandatory.
• When complete “start-up” above, the left display window shows “–”, the right display window shows ambient temperature value.
• Push the power switch to “ON”(1) position.
• The default temperature setting is 20°C, shown on the left display window.
• If the ambient temperature is lower than default temperature, the electrodes start sparking, after 7 seconds, the heater starts.
• If the ambient temperature is higher than default temperature, turn thermostat control knob to desired temperature, the electrodes start sparking, after 7 seconds, the heater starts.

COLD START UP

• At low temperature keep the air vent hole fig.4 closed by a finger during ignition to make start-up easier.
• ABNORMAL OPERATION: in case of malfunction (flame failure, reduced air flow, bad combustion, etc.) the heater stops and the indicator light starts FLASHING (THE LOCK-OUT MODE code will be showed on the display window).

MANUAL REST/RESTART

• If the heater is in lock-out mode, check and remove the cause of lock-out before restarting the heater.
• To reset, turn the ON/OFF switch to 0 and then again to I. In case of repeated malfunction, call technical service.
• Turning the thermostat control knob will NOT reset the heater.

SHUT DOWN

• Move switch to “OFF” (O) position. Unplug the unit when not used for a long time.

• Never disconnect the heater from mains to stop it while in operation. Always allow the cooling sequence to be completed, otherwise the residual heat could damage internal components.

• DO NOT cover the heater.

• DO NOT block the air inlet and outlet.

• WARNING! The heater outlet is very hot during operation and after use. DO NOT TOUCH! Use personal protecting equipment if needed.

• WARNING! Children should be supervised to ensure that they do not play with the appliance.
  Note: The appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.
  Unplug the heater before moving it. Never pull the cable to unplug or move the unit.

• DO NOT leave the heater unattended when in use.

• Never use the appliance with wet hands or when either the heater or the power cable is wet.

• WARNING! If the supply cable is damaged, it must be replaced by the manufacturer, by a service agent or a similar qualified person.

CLEANING & MAINTENANCE

• WARNING! Before starting any maintenance task, shut down, unplug and let the heater cool down for at least 15 minutes.
• DO NOT attempt any electrical repair yourself. If the heater needs service or repair, contact a qualified technician.
• DO NOT use a faulty unit unless a qualified technician has inspected and repaired it.
• When cleaning, make sure that water does not enter the unit.
• DO NOT open the enclosure to clean the inner parts. DO NOT spray water into the heater.
• Never use solvents, gasoline, toluene and similar aggressive chemicals to clean the heater.

Regularly wipe the enclosure using a soft sponge or cloth. For very dirty parts, use a sponge wetted with lukewarm water and a mild detergent, then dry using a clean cloth.
Keep air inlet and fan free from dust and dirt. To clean inner parts, gently blow compressed air through air inlet.
Regularly inspect the power cable: if worn, cracked or damaged have it replaced by technical service.
Before storing the heater, make sure it is perfectly cool and dry. Cover the unit with a plastic bag, put it in its packing box and store it in a dry, ventilated place.

LONG TERM STORAGE

If the heater is to be stored for a long period of time, drain the fuel through the fuel cap opening. Rinse and swirl a small amount of fuel within the tank and then empty it fully. When you come to use the heater again do not use old fuel which has been stored from the previous season. Use of old fuel can damage your heater.
Although our heaters operate with diesel fuel, when the temperature is below 0°C diesel additives are required to maintain the diesel’s viscosity. Typically diesel can cloud in freezing conditions and will start to gel. You will need additives for your fuel in these conditions. Kerosene does not start to gel until the ambient temperature is around -40°C.

Refer to fig.1B below.
DO NOT use paraffin in these heaters.

MAINTENANCE
The following checks BY QUALIFIED PERSONNEL ONLY are recommended before every seasonal use:

Nozzle Carefully unscrew nozzle from nozzle fitting. Blow compressed air through nozzle orifice to free it from dirt. Replace nozzle if necessary.
Air Filters Clean air filters. Remove filter end cover (11), wash air intake filter (10) using a light detergent and dry it thoroughly before re- installing. Replace air delivery filter (9) once a year fig.2. 

Ignition Electrodes fig.3
Clean and if necessary replace the ignition electrode. For electrode gaps see fig.3.

Compressor Pressure Adjustment fig.4

WARNING! The compressor pressure is factory set and must be checked by qualified technicians only. Tampering with the
unit may be dangerous.
Remove pressure gauge cap. Connect a pressure gauge on the pressure measuring port on the rear guard. Start heater and read air pressure value. If necessary adjust pressure to correct value by turning the adjusting screw (the air vent hole in the adjusting screw middle) clockwise to increase, anticlockwise to decrease the pressure.
