The fan must be turned on to operate the air conditioner. The fan speed control and all air vents must be
adjusted to achieve the best possible interior cooling performance.
Under normal operating conditions and with doors and windows closed, the cab temperature is reduced by
6 °C to 15 °C (10 °F to 25 °F) compared to outside temperature. When operating the air conditioning system,
the air humidity level of the cab interior is reduced.
Note:

During cold weather, with ambient temperature above 32 ºF (0 ºC) operate the air conditioner at
least once per month, for a period of 10 to 15 minutes. This will lubricate the seals to prevent
them becoming brittle and help prevent the loss of refrigerant from the system.

The system is equipped with an environmentally safe refrigerant, R134a. Never recharge the air
conditioning system with refrigerant other than R134a as this will result in loss of cooling and
permanent damage to all air conditioning components.
Push the button to light on and push it again to light off.
