Air Conditioner/Heater 9960 Self-Propelled Peanut Combine
176 06/03/05 MAN091
System Overview
The air conditioning/heating system
functions as follows:
A – Holes
B – Air duct
C – Pressurizer fan
D – Pre-cleaner
E – Fresh air filter
F – Recirculating filter
G – Recirculator blower
H – Ducts
1. Air is drawn into the cab through holes
(A).
2. This air flows down the air duct (B) and
into the pressurizer fan (C).
3. Air is then pushed through the pre-
cleaner (D) where the majority of the dirt
and a small amount of air is discharged
through the cab floor. Always make
sure this area is open.
4. The cleaned air then passes through the
fresh air filter (E) into the evaporator
compartment.
5. The air is mixed with air from inside the
cab, and is drawn into the elevator
compartment through the recirculating
filter (F).
6. It then passes through the evaporator
and heater core.
7. Treated air (heated or cooled) is drawn
into the recirculator blower (G) and
discharged into the cab through ducts
(H).
Special equipment and procedures are
required to service the air conditioning
system. See your AMADAS/John Deere
dealer for more information.
Refrigerant (R134A) is under pressure.
Improper servicing may cause refrigerant
to penetrate eyes and skin or cause burns.
