Air conditioner switch
To operate the air conditioner the blower must be on the blower speed temperature control and all vents
must be adjusted to obtain the best cooling for the ambient temperature and dust conditions.
Under normal operating conditions, and the windows and doors closed, temperatures in the cab of 6 ºC to 15
ºC (10 ºF to 25 ºF) less than the ambient temperature will occur. When operating the air conditioner system,
the moisture level is decreased.
Note:
1) During cold weather, with ambient temperature above 0 ºC (32 ºF) 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.
2) 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.
