OUTLINE OF CONSTRUCTION
A6E850201038T01
•
The construction and operation of the air conditioner system is essentially carried over from that of the previous
PREMACY (CP) model, except for the following features. (See PREMACY Training Manual 3336-1*-99C.)
(See PREMACY Training Manual 3351-1A-01A.)

FEATURES
A6E850201038T02
Improved air Conditioning Performance
•
A sub-cooling system integrating the condenser and receiver/drier has been adopted to facilitate evaporator
operation. This system also reduces the number of parts and the amount of refrigerant.
Improved Visibility
•
To improve windshield and front door glass defogging, the climate control unit is designed to automatically turn
the air intake mode to FRESH when the airflow mode selector dial is turned to DEFROSTER position.
Reduce Weight
•
The A/C unit integrating the cooling unit and heater unit has been adopted to reduce weight.
