Redirect the louvers for air outlets (A), (C), (D), and (E) by hand to the desired direction. The louvers for air outlet (B) cannot be redirected.
The climate control panel is located under the right window inside the cab:

|
Main Power ON/OFF Switch (1) - Push the ON/OFF switch in order to power on the system. Push the switch again in order to power off the system. |
|
Automatic Control Switch (2) - In order to enter the full "AUT" mode for automatic climate control, push this switch. However, if you push the switch again, you cannot turn off the air conditioning. When the system is in full "AUT" mode, you can manually change specific functions by pushing another switch. If you manually change a specific function, "AUT" does not appear in the display, but the unchanged functions will remain in "AUT" mode. Even on a day that is sunny, a climate control system with only a heater can cool the cab in full "AUT" mode if the ambient temperature is no more than |
The climate control unit provides excellent operator comfort in the full "AUT" setting. Press the "AUT" switch for full "AUT" mode. Push temperature switch (3) in order to set the desired temperature. The temperature is only shown in metric values. All other functions of climate control will be handled automatically.
In order to take advantage of the full "AUT" setting of the climate control system, always keep the sunlight sensor clean. Do not obstruct the sunlight sensor. If the climate control system is in the full "AUT" setting at engine start-up and the temperature inside the cab is too warm or too cool, the damper for fresh air ventilation may automatically close for a few minutes. This will help to bring the air temperature to the preset temperature more quickly.
|
Temperature Switch (3) - These switches control the temperature of the air that is coming from the air outlets in order to achieve the preset temperature. This preset temperature appears on LCD panel (4). If the heating and air conditioning system is in the automatic mode, pushing these switches changes the preset temperature. |
|
Increase - Push this switch in order to increase the temperature of the air that is coming out of the air outlets or push this switch in order to increase the preset temperature. |
|
Decrease - Push this switch in order to decrease the temperature of the air that is coming out of the air outlets or push this switch in order to decrease the preset temperature. |
|
Fan Switch (5) - The fan switch directly controls the fan speed. If the climate control system is operating in the automatic mode, pushing this switch overrides the automatically selected fan speed. |
|
|
Increase - Push this switch in order to increase the fan speed. |
|
|
Decrease - Push this switch in order to decrease the fan speed. |
|
Compressor Switch (6) - Push the switch in order to turn on the compressor or push the switch in order to turn off the compressor. In humid conditions, the compressor may be used to remove moisture from the air in the cab. In cool weather, operate the compressor weekly in order to prevent leakage of the refrigerant gas. This will also help to maintain the compressor in optimum working order. |
|
Defrost (7) - Depressing this switch will defog the windows. The air will also be dehumidified while the compressor is running. This selection directs air flow out of air outlet (C) and air outlet (D). |
Air Inlet Select Switch (8) - This switch selects the position of the air inlet.
|
Recirculate - When this position is selected, the air inlet is closed. The air will recirculate inside the cab. |
|
Fresh Air - When this position is selected, the air inlet is open. Fresh air will circulate into the cab. |
Air Outlet Select Switch (9) - This switch selects the position of each air outlet. Each switch controls a different air outlet.
|
Upper Body - Selecting this switch will open air outlet (A) and air outlet (D). |
|
Upper Body and Floor - Selecting this switch will open air outlet (A), air outlet (B) and air outlet (D). |
|
Floor - Selecting this switch will open air outlet (B). |
|
Floor and Defroster - Selecting this switch will open air outlet (B) and air outlets (C) and (D). |
Consult with your Caterpillar dealer for periodic maintenance of the heating and air conditioning system.
In order to convert the temperature reading from Degrees Celsius to Degrees Fahrenheit, depress both keys of the fan switch at the same time for five seconds. The same action is used for converting the temperature reading from Degrees Fahrenheit to Degrees Celsius.
