The Manual Diagnostic menu, shown in Figure 22, is used for troubleshooting 
and testing the system on a component basis. It allows the service technician to 
turn individual components of the system on and off for troubleshooting pur-
poses. Pressing the BACK button returns the display to the Main menu and 
turns off all the active loads.

The items shown in Table 25 are for the first barrel in the unit only. The list 
includes additional components with their related barrel number, i.e. Hot Gas Sol 
#2, etc.

CAUTION: The compressor can suffer damage if it is allowed 
to run without either a hot gas defrost or liquid line solenoid 
open. The software is designed to turn on the hot gas sole-
noid for a barrel to prevent damage from occurring.
