(Figure 7.9.3)
Air conditioning system controls are located on ”ECS” panel, CAS messages
are grouped on MFD unit. Conditioning occurs when ”BLEED VALVE” switch
is set to ”ON” ; this leads to opening of pressure regulation valve and leads to
”BLEED OFF” CAS message disappearance, requested pressure level is
obtained by ”HI LO” switch position.
An overheating detector leads to the ”BLEED TEMP” CAS message
appearance and simultaneously shuts off the pressure regulation valve if
temperature increases abnormally at cooling turbine compressor outlet.
System cannot be reactivated as long as ”BLEED TEMP” CAS message is
displayed. After ”BLEED TEMP” CAS message has disappeared, set
”BLEED VALVE” switch to ”OFF”, then to ”ON” to reactivate the system.
”CABIN FAN” switch controls the operation of the fan for the fresh air
distribution system and allows selecting two ventilation speeds. The
requested temperature in the cabin may be modified by the ”CABIN TEMP”
control.
The quantity of conditioning air used for windshield defogging may be
modified by the ”DEFOG--NORMAL” control.
Emergency ventilation control ”EMERGENCY RAM AIR”, located under R.H.
instrument panel facing control wheel, allows outside air to enter the cabin
through a valve. In ”NORMAL” position, the valve is shut off and the control is
locked. To open emergency ventilation valve, press on locking knob and
move control rearwards.
