AIR CONDITIONER (A/C) OPERATION
• When the air conditioner is set to the
recirculation mode, the air in the cab
gradually becomes dirty, so switch to
external air ventilate once a comfortable
temperature is reached.
• Excessive cooling can be harmful to
your health. It is best to keep the air
inside the cab only about 5 to 6°C (41 to
43°F) cooler than the outside air.
• If the excavator has been parked in the
sun, open the windows or door to let
the hot air out of the cab before using
the air conditioner.
The ATC automatically controls the Heater-
A/C to maintain the cab air temperature close
to the set point selected with the temperature
control pushbuttons. The ATC will adjust the
air temperature blown through the ducts to
maintain this temperature. If more cooling is
desired, decrease the set point by pushing
the down temperature button.
To obtain maximum cooling, set the set point
temperature to 16°C (60°F). The system will
put out maximum cooling continuously, even
if the cab temperature drops below the set
point temperature. Turn the blower fan speed
to maximum fan (not AUTO).
In AUTO mode, the fan speed will be adjusted
as necessary to keep the cab at the set point
temperature. The farther away the cab
temperature is from the set point, the higher
the fan speed.
Finer temperature control can be obtained by
leaving the control panel in °F units. The
temperature units can be changed from °C to
°F or °F to °C by toggling the °C/°F button.
The current temperature unit will then be
shown on the digital display.
A comfortable set point for cooling is between
20°C (68°F) and 23°C (74°F). Change the
temperature set point in small amounts for
best results. Once a comfortable temperature
is reached, this temperature will be
maintained without adjusting the set point.
VENTILATION (FRESH /RECIRC)
The unit draws in a mix of outside and
recirculated air when in fresh air mode. This
allows the cab to maintain a positive cab air
pressure to prevent excessive dust from
entering the cab. In addition, the fresh air
mode prevents the air from becoming stale
and humid.
In recirculation mode, only recirculated air is
pulled in through the unit. Use this mode for
short periods of time to prevent fumes from
entering the cab or to obtain maximum
cooling or heating.
Inspect and replace both the fresh air and
recirculated air filters regularly to obtain
proper cab pressurization, optimized unit
performance, and correct temperature
regulation.
OUTLETS
Move the louvers to adjust the air flow
direction.
