OPERATING INSTRUCTIONS
CAB AIR DISTRIBUTION
Equal distribution of air is important in maintaining a constant cab interior
temperature. For best performance, all vents should remain open to allow
the AUTO mode to function properly.
To maintain the selected cab temperature the AUTO mode may provide an
air temperature from the vents that differs from the temperature set point.
To ensure proper operation, it is recommended the driver redirects the air
instead of adjusting the temperature set point or closing the vent. The
system may have difficulties in obtaining the desired cabin temperature if
the temperature setting is repeatedly changed.
Outside Air/Recirculation Air
Selecting air recirculation mode completely isolates the cab interior from
the outside air. This mode is helpful in preventing dust, pollen, and odours
from entering the cab. Additionally, recirculation mode can reduce the
amount of time needed to cool down the vehicle while in maximum cool
down. Note this mode may increase fogging on the windscreen. A coarse
air filter is provided for recirculation air and is located behind the fuse panel
on the passenger side.
The outside air mode provides for 100% outside air into the cab. This mode
is helpful with windscreen defogging. A pleated air filter located under the
hood provides filtration for dust, pollen and debris.
