outside Air will still be pulled into the cab.
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 6ºC
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
