OPTIONS, ATTACHMENTS 28.2 METHOD OF OPERATION If the temperature control switch is set during defrosting so all lamps are red, this will improve the performance for defrosting and demisting. Set the vent mode selector switch to the intermediate position to give the desired condition. With the FACE vents, it is possible to adjust the direction of the air flow and to turn it on or off. However, do not set to the FACE mode with the vents closed. 28.2.1 WHEN NOT USING THE AIR CONDITIONER REGU- LARLY The compressor requires regular lubrication to preserve and protect moving parts.
Maintain the compressor lubrication by occasionally operating the system (cooling, dehumidifying and heating) for a few minutes, regardless of weather. REMARKS When temperature in the cab already is low, the air conditioner may not operate. In such cases, warm the air inside the cab by recirculat- ing, and then turn on the air conditioner. 28.3 COOL BOX This compartment can keep small items cool (when the cooling is being used) or warm (when the heating is being used). When using the box, open the vent grill. When not using the box, close the grill. Do not use the cool box for things with strong odors or which leak water or break easily.
Do not use it as a holder for tools or similar objects.
