When carrying out the defrosting, if the temperature control
switch is set so that all lamps are red, this will improve the per-
formance 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.
When not using the air conditioner regularly
Run the air conditioner at cooling or dehumidification + heating
for several minutes from time to time to prevent the loss of the oil
film at various parts of the compressor.
REMARK
If the temperature inside the cab is low, the air conditioner
may not work. In such cases, use the recirculated air to
heat up the inside of the cab, then turn the air conditioner
switch on to run the air conditioner.
