Air Conditioning and Heating System
Air is drawn into the cab through air intake vents
(A). This air flows down air duct (B) and into the
pressurizer fan (C). The air is then pushed through
the pre cleaner (D) where the majority of dirt and
a small amount of air is discharged out through
the cab floor. Be certain this opening is clear (see
Figure 87).
This cleaned air then passes through fresh air filter
(E) into the evaporator compartment. The air is now
mixed with air from inside the cab, being drawn into
the evaporator compartment through the recircu-
lating filter (F) and the evaporator filter. The air is
then drawn through the evaporator / heater core (I).
Treated air (heated or cooled) is now drawn into
the recirculating blower (G) and discharged into the
cab through air vents (H). Air conditioning system
low pressure switch (J) is located left of the evapo-
rator compartment.
