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, with 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 temperatures 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.
