Evaporator CPR Adjustment  
D 
* The CPR adjustment must be INCREASED by approximately +0.5 psi for 
every additional foot (+0.1 bar per meter) that the evaporator is located 
(distance D minus 6”) from the front wall of the vehicle. 
When the setting has been adjusted, tighten the 
jam nut securely against the setting screw to 
prevent any vibration of the set screw (and to 
prevent disruption of the CPR setting). 
Replace the CPR cap and remove gauges.
