Sterling 360 - Outside Air Inlets

8-11
CAUTION
• Do not run the air conditioner without refrig-
erant. This will damage the air conditioner
compressor. Check the refrigerant level if the
air conditioner does not work efficiently.
• Never use any refrigerant other than HFC-
134a. Other refrigerants will cause a mal-
function of the air conditioning system.
NOTE:
Do not release refrigerant into the atmosphere. If it
becomes necessary to discharge the refrigerant,
consult the nearest authorized Sterling service facil-
ity to have the refrigerant removed properly.
To protect the environment, your vehicle’s air condi-
tioning system uses refrigerant HFC-134a which
does not harm the ozone layer.
Since charging the system with this refrigerant
requires a method different from the conventional
method, be sure to contact an authorized Sterling
service facility to service your A/C.
4 Cleaning the HVAC air filters
Clean the air filters in the heating, ventilation, and
air conditioning (HVAC) system every 6 months.
A dust-loaded HVAC filter can cause malfunction of
the blower motor. P. 11-60
The outside air inlets allow fresh outside air to flow
through the front air outlets when fresh air is
selected. They must not be obstructed.
• Make sure the outside air inlets are not cov-
ered or otherwise obstructed. Remove any
object that covers or obstructs an air inlet.
• Do not directly apply steam from a cleaner to the
outside air inlets. Water could enter the cab, and
cause the wiper motor to malfunction.
