FIGURE 5 - ARROW = PRESSURE RELIEF VALVE
Since October 1981, receiver-dryers with pressure relief valve (arrow) were installed. This valve will discharge refrigerant at approximately 40 +/- 5 bar
/ 580 +/- 73 psi and win close again at approximately 5 bar / 73 psi below opening pressure. This will prevent the discharging of the entire refrigerant
charge. The pressure relief valve can be replaced by itself (Figure 5).
NOTE:
The new pressure relief valve cannot be installed on the previous receiver-dryer with temperature sensitive pressure relief plug due to a
modified seal and assembly thread.
FIGURE 6ARROW = 52~C TEMPERATURE SWITCH
Since November 1981, a 52~C auxiliary fan cut-in switch has been installed on the receiver-dryer (arrow) same as on diesel models. The previous cut-in
temperature was 62~C (Figure 6).
When making repairs use only the 52~C switch.
