Fig. AC-8 Air flow - VENT (Ventilation) position
1. Air intake door. .. Vacuum is
introduced to the actuator of the air
intake door and causes an actuator
movement to open the door.
Thus it admits outside air into the
air conditioner unit.
2. Mode door. .. The mode door is
in the closed position. Outside air is
directed to the outlets located on the
instrument panel.
3. Heater door ... The heater door
is in the open position.
4. Vacuum cock ... The vacuum
cock is in the closed position, shutting
AC-8
off the hot water at the cock.
5. Fast idle actuator.. . The vacuum
flowing into the fast idle actuator
is interrupted by the magnet valve.
The actuator then stops its operation
and the operating lever returns to its
original position.
