SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers
to an CFC-12 (R-12) A/C system. The HFC-134a (R-134a) cou-
plers will not properly connect to the CFC-12 (R-12) system.
However, if an improper connection is attempted, discharging
and contamination may occur.

REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and
specified lubricants have been used with the scale. If the scale
controls refrigerant flow electronically, the hose fitting must be
1/2²-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may
be vented into air from cylinder's top valve when filling the cylin-
der with refrigerant. Also, the accuracy of the cylinder is gener-
ally less than that of an electronic scale or of quality recycle/
recharge equipment.

OPERATION OF AIR MIX DOOR MOTOR
lExamplep1
When the temperature in the vehicle is lower than the set
temperature.
When the temperature in the vehicle is low, in-vehicle sen-
sor resistance is great and the input voltage to the auto
amplifier becomes great. As a result, the voltage from the air
mix door position arithmetic circuit also becomes great.
When this voltage is greater than the voltage from the PBR,
comparator (1), Tr
p1and Trp4turn ON.
Accordingly terminal No.
p12becomes!and terminal No.
p13becomes@. The air mix door motor rotates clockwise and
the air mix door moves toward the ªHOTº side.
As the air mix door moves toward the ªHOTº side, the volt-
age from the PBR becomes greater and consequently
becomes equal to that from the air mix door position arith-
metic circuit. As a result, comparator (1) turns OFF and the
air mix door motor stops.

lExamplep2
When the temperature in the vehicle is higher than the set
temperature.
When the temperature in the vehicle is high, in-vehicle sen-
sor resistance is small and the input voltage to the auto
amplifier becomes small. As a result, the voltage from the air
mix door position arithmetic circuit also becomes small.
When this voltage is smaller than the voltage from the PBR,
comparator (2), Tr
p2and Trp3turn ON.
Accordingly terminal No.
p13becomes!and terminal No.
p12becomes@. The air mix door motor rotates counterclock-
wise and the air mix door moves toward the ªCOLDº side.
As the air mix door moves toward the ªCOLDº side, the volt-
age from the PBR becomes smaller and consequently
becomes equal to that from the air mix door position arith-
metic circuit. As a result, comparator (2) turns OFF and the
air mix door motor stops.
AIR MIX DOOR MOTOR
The air mix door motor is attached to the heater unit. It rotates
so that the air mix door is opened to a position set by the auto
amplifier. Motor rotation is conveyed through a shaft. The air mix
door position is then fed back to the auto amplifier by the PBR
built into the air mix door motor.
