and co-pilots seats.  
Forward (Flight Deck) Evaporators Mounted on either side of the center pedestal below the 
instrument panel in the chin bubble area. 
Aft (Main Cabin) Evaporators Forward of the main rotor transmission on the 
transmission deck.  
Condenser Assembly Forward of the main rotor transmission between the two 
aft (cabin) evaporators on the transmission deck. 
Compressor Assembly Mounted to the forward right hand side of the main rotor 
transmission and is driven off the transmission quill. 
Refrigerant Plumbing 
Routed from the compressor, to the condenser and all 
the other components. 
(As the refrigerant plumbing connects the compressor,
