surizing
When defrosting, set the temperature control switch so that all
lamps are red. This will improve 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 in cooling or dehumidification + heating mode for several minutes from time to time to pre-
vent the loss of the oil film in 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
warm up the inside of the cab, then turn the air conditioner switch on. The air conditioner will be run.
