PREVENTIVE MAINTENANCE
CAB HEATER/AIRCONDITIONING
The combination heater/airconditioner provides comfort for those in
the cab through accurate control of the cab environment in all weather
conditions. Regular attention to the items below will help you keep the
heater/airconditioner performance at an optimal level.
Keep the vehicle’s ventilation system, engine exhaust system and cab/
sleeper joints properly maintained. It is recommended the vehicle’s exhaust
system and cab/sleeper be serviced as follows:
• Inspected by a competent technician every 10,000 kilometres.
• Whenever a change is noticed in the sound of the exhaust system.
• Whenever the exhaust system, underbody, cab or sleeper is
damaged.
To allow for proper operation of the vehicle ventilation system:
• Keep the inlet grille clear of leaves and other debris at all times.
•
Inspect and clean fresh air inlet filter and recirculation filter to HVAC
unit at 10,000 kilometre intervals. This inspection is dependant on
the vehicle's service application and may need to occur more often
if operating in dusty conditions.
• Keep the exhaust pipe area clear to help reduce the buildup of
exhaust gas under the vehicle.
SPECIAL PRECAUTIONS
Excessive heat may cause the pressurised components of the
airconditioning system to explode. Never weld, solder, steam clean
or use a blowtorch near any part of the airconditioning system.
If a refrigerant leak develops in the presence of excessive heat or an open
flame, hazardous gases may be generated. These gases may cause
unconsciousness or death. If you become aware of a refrigerant leak
on your vehicle, have your system serviced immediately and observe any
warnings.
