T = Temperature (C°) and High Pressure  
(Bars).  
P = Low pressure (Bars).  
Te = Exterior temperature (C°).  
HP = Pressure at compressor outlet (Bars).  
Ta = Temperature of air blown from the  
central air vents (C°).  
BP = Pressure at compressor inlet (Bars).

XANTIA - XUD  
AIR CONDITIONING SYSTEM R134.a  
(1) - High pressure valve  
(2) - Low pressure valve  
Air conditioned XANTIA XUD All Types are equipped with a new  
"HARRISON" refrigeration compressor, with variable capacity.  
All other models are fitted with a "SANDEN" compressor.  
Parts modified.  
(5) - "HARRISON" variable capacity compressor, reference  
"DELPHI V5".  
(3) - Air conditioning pipes, secured to the compressor with nuts  
instead of clamps.  
(4) - Modified seals to suit the new attachments.Belt length : 1710 mm  
instead of 1700 mm.
