1B Ð 20 AIR CONDITIONING
1) Make sure the evacuation process is correctly
completed.
2) Connect the center-hose of the manifold gauge to the
refrigerant container.
·Turn the charge valve handle counterclockwise to
purge the charging line and purge any air existing
in the center-hose of the manifold gauge.
3) Open the low-pressure hand valve and charge the
refrigerant about 200 g(0.44 lbs.).
·Make sure the high-pressure hand valve is closed.
·Avoid charging the refrigerant by turning the
refrigerant container upside down.
4) Close the low-pressure hand valve of the manifold
gauge.
·Check to ensure that the degree of pressure does
not charge.
5) Check the refrigerant leaks by using a HFC-134a leak
detector.
·If a leak occurs, repair the leak connection, and
start all over again from the first step of
evacuation.
6) If no leaks are found, open the low-pressure hand
valve of the manifold gauge.Then continue charging
refrigerant to the system.
·When charging the system becomes difficult:
(1) Run the engine at Idling and close the all
vehicle doors.
(2) A/C switch is ÒONÓ.
(3) Set the fan control knob (fan switch) to its
highest position.
WARNING
BE ABSOLUTELY SURE NOT TO OPEN THE HIGH-
PRESSURE HAND VALVE. SHOULD THE HIGH-
PRESSURE HAND VALVE BE OPENED, THE HIGH-
PRESSURE REFRIGERANT GAS WOULD FLOW
BACKWARD, AND THIS MAY CAUSE THE
REFRIGERANT CONTAINER TO BURST.
7) When the refrigerant container is emptied, use the
following procedure to replace it with a new
refrigerant container.
(1) Close the low pressure hand valve.
(2) Raise the needle upward and remove the charge
valve.
(3) Reinstall the charge valve to the new refrigerant
container.
(4) Purge any air existing in the center hose of the
manifold gauge.

(4) Sliding Contact
The mode and mix actuators are common actuators
with the built-in potentiometer. For the intake
actuator, the contact switch type is selected.
The potentiometer is a register assembled to the
printed circuit board of the mix and mode
actuators. It detects the air mix door position
specified by rotation of the output axis as a ratio of
the variable terminal (VM) voltage against the
reference voltage (VDD: 5V), then signals the value
to the automatic heater/air conditioner control unit.¥ Movement of Mix Actuator
Position of the air mix door is determined by the
controller on the automatic heater/air conditioner
control unit.
As the heat or cool side of the controller is
grounded, the transistor on the driver is activated
and, thus, the motor rotation is turned on. The
sliding contact connected to the motor sends the
position detection signal from the potentiometer
to the automatic heater/air conditioner control
unit. As the set temperature and interior
temperature are balanced, the controller returns
to the neutral and the motor rotation is stopped.
