Service Mode
CAUTION
!
Service Mode MUST be used whenever
removing refrigerant charge, refrigerant
leak checking or evacuating.
NOTE
If the START/RUN - OFF switch is toggled to
the OFF position, the System will exit Ser-
vice Mode.
To enter Service Mode:
1. Enter the Technicians Menu, highlight SERVICE
MODE and then press the “=” key as described
in
2. “TRANSITION TO SERVICE MODE” and then
“ENTERING SERVICE MODE” will display in
the operator message panel. When entering
Service Mode the control system brings the
CSMV, EVXV and ECXV to 100% open and
energizes LIV.
3. Once the modulating valves are 100% open, “
RECOVER / LEAK CHK / EVAC MODE” is dis-
played in the operator message panel.
4. Refrigerant recovery, leak checking, or evacua-
tion may be performed on the unit at this time.
Refer to Service Procedures in
5. The unit should remain in the RECOVER / LEAK
CHK / EVAC MODE as refrigerant recovery or
leak testing procedures are performed.
6. If the message in the operator message panel
changes to “CHARGE MODE - HOLD = TO
EXIT” do not continue refrigerant recovery, leak
testing or evacuation procedures. Exit Service

“RECOVER / LEAK CHK / EVAC MODE” is dis-
played in the operator message panel before
continuing refrigerant recovery or leak testing.
7. During evacuation, the control system will moni-
tor the pressure transducer readings.
• The System will remain in “RECOVER /
LEAK CHK / EVAC MODE” as evacuation is
started.
• As the refrigeration system is evacuated, the
system pressure will go into a deep vacuum.
Once the CSP is less than 20 inhg and the
CDP is less than +5 psig the operator mes-
sage panel will change to “EVAC/ CHARGE
MODE”. The position of the modulating
valves and LIV do not change in this mode.
• Following the evacuation, as the charging
procedures are started the control system will
bring the modulating valves to 0% open and
de–energize LIV when both of the transduc-
ers rise above +5psig (0.34 bar).
• When the modulating valves are closed,
“CHARGE MODE – HOLD = TO EXIT” is dis-
played in the operator message panel. This
action is taken to prevent refrigerant migra-
tion to the compressor during charging.
8. To exit Service Mode at any time, press the
EXIT soft key. “EXITING SERVICE MODE” will
then display in the operator message panel.
When Service Mode is exited, the control sys-
tem brings the modulating valves to 0% open
and LIV will be de–energized.
NOTICE
Technician Mode should be canceled
when work is complete. If Technician
Mode is not canceled, Technician Mode
will be available for 60 minutes after the
last key press without requiring a code,
even after placing the SROS in the OFF
and then back in the RUN/STOP position.
9. Once activity requiring use of Technician Mode
is complete, Technician Mode should be manu-
ally canceled, refer to
