INTRODUCTION Note to the Owner WARNINGS FOR AIR CONDITIONING SYSTEM REPAIR OPERATIONS Starting the system at low temperatures can damage the compressor. Only operate the air conditioner when the engine is hot and the temperature inside the cab is at least 20 °C (68.00 °F). When disconnecting the hoses, close the ends with plastic caps to prevent foreign matter and humidity from getting inside the hoses. Handle the thermostatic sensor carefully to avoid damage that may prevent efficient system operation. Always use two spanners to unscrew the hose fittings to avoid twisting the fitting. Do not use any type of engine oil to lubricate the compressor and the system. Never leave the compressor oil container open, always make sure that it is tightly closed. If left exposed the oil will absorb humidity from the air and may, subsequently, damage the system. Do not transfer compressor oil from the original container to another container. Do not introduce any additives to the compressor oil. Any additional substances could contain elements which are incompatible with the chemical base of the refrigerant and thus alter its characteristics. Check that the thermostatic sensor is correctly inserted in the fins on the evaporator to ensure efficient system operation. 47711469 30/05/2014 4
