Keep the power cable away from heat sources, sharp edges, cutting and moving parts.
DO NOT expose directly to the weather or to excessive humidity.

DO NOT place the heater in the immediate surroundings of a bath, shower, or swimming pool.
Follow general and special fire safety regulations in force in all fields of application. In any case, ensure the following minimum safety clearances from materials or objects in the surroundings of the heater:
Side: 1.2m, top: 1.2m, Rear: 1.2m, Air outlet side: 2.4m
Floors and ceilings must be made of fireproof materials in the place where the heater is operated.

DO NOT connect direct-fired heaters to air ducts

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 the 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 that complies with the requirements set out in local authority regulations.

WARNING! Air contaminants taken into the heater may affect the heat output, damage the unit, and cause health problems. Example: Bodyshop filler dust/paint overspray will damage the motor bearing, clog the filter and pump, and contaminate the combustion, 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)

START UP

Fill the tank with clean fuel. Only use Diesel or Kerosene. The fuel gauge on top of the tank allows you to check the fuel level.
Connect the power cord plug to a AC220-240V 50 Hz earthed electrical supply system. Earthing is mandatory.
When the complete “start-up” above, the left display window shows “–”, the right display window shows the ambient temperature value.

Push the power switch to the “ON”(1) position.
The default temperature setting is 20°C, shown on the left display window.
If the ambient temperature is lower than the default temperature, the electrodes start sparking. After 7 seconds, the heater starts.

If the ambient temperature is higher than the default temperature, turn the thermostat control knob to the desired temperature. The electrodes start sparking, and 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 shown on the display window).

MANUAL REST/RESTART

If the heater is in lock-out mode, check and remove the cause of the 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 the switch to the “OFF” (O) position. Unplug the unit when not used for a long time.

Never disconnect the heater from the 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 protective 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 a 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 by 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, or 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 the air inlet and fan free from dust and dirt. To clean the inner parts, gently blow compressed air through the 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 that 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 the nozzle from the nozzle fitting. Blow compressed air through the 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 to the pressure measuring port on the rear guard. Start the heater and read the air pressure value. If necessary, adjust the pressure to the correct value by turning the adjusting screw (the air vent hole in the adjusting screw middle) clockwise to increase, anticlockwise to decrease the pressure.
