5.2.3 Service Mode

CAUTION
Service Mode MUST be used whenever re-
moving refrigerant charge, refrigerant leak
checking or evacuating.
NOTE
If the Main Power switch is toggled to the OFF
position, the microprocessor will exit service
Mode.
To enter Service Mode:
a. Enter the Technician Interface - Service Mode as de-
scribed in Section 5.2.
b. "ENTERING SERVICE MODE" will display in the
MessageCenter.
When entering Service Mode the microprocessor opens
the CSMV and EXV to 100% open.
c. Once the valves are open, "RECOVER / LEAK CHK /
EVAC MODE" is displayed in the MessageCenter.
d. Refrigerant recovery, leak checking, or evacuation
may be performed on the unit at this time. Refer to
Service Procedures in Section 8.
e. The unit should remain in the RECOVER / LEAK CHK
/ EVAC MODE as these service procedures are per-

formed. If the unit shifts to Charge Mode and
"CHARGE MODE – HOLD = TO EXIT" is displayed in
the MessageCenter, DO NOT perform refrigerant re-
covery, leak checking, or evacuation. Exit Service
Mode and then re-enter, making sure that "RE-
COVER / LEAK CHK / EVAC MODE" is displayed in
the MessageCenter before continuing any of these
service procedures.
f. The microprocessor will monitor the pressure trans-
ducer readings during evacuation. Once all pressure
transducers (CDP, CSP and EVOP) have dropped
below –20 inhg (0.68 Bar) and then 2 of the 3 pressure
transducers rise above 5 PSIG (0.34 Bar ), the micro-
processor will close CSMV and EXV to 0% open.
When the valves are closed, "CHARGE MODE –
HOLD = TO EXIT" is displayed in the Mes-
sageCenter. This action is taken to prevent refriger-
ant migration to the compressor during charging,
g. To exit Service Mode at any time, press and hold the
"=" key for 3 seconds. "EXITING SERVICE MODE"
will then display in the MessageCenter.

5.3 PC MODE

PC Mode allows the technician to access the
microprocessor without the engine running and without
the refrigeration system running. When in PC Mode the
microprocessor is fully functional and all Operator
Interfaces may be performed, the operation of the
microprocessor may be demonstrated and all PC
functions may be performed, again, without the unit
actually operating.
