1. With the system powered up (START/RUN-OFF switch in the START/RUN position) press the MANUAL
DEFROST key.
NOTE
This procedure may be demonstrated in PC Mode but the unit will not actually enter defrost.
2. If the conditions for defrost are met, the status bar and the Box Temperature display will change to the word
“DEFROST”. The MessageCenter will display “DEFROST CYCLE STARTED” for 10 seconds. At the com-
pletion of any defrost cycle, the MessageCenter will return to the default display.
3. If the conditions for defrost are not met, the MessageCenter will display “CANNOT START DEFROST
CYCLE” for 5 seconds. This message will be activated when:
• The box temperature is too warm. Defrost may be entered when the defrost termination temperature sen-
sor (1DTT) is below 40°F (4.4°C) or the supply air temperature sensor (1SAT) is below 45°F (7.2°C) OR
• The engine has not run at least 15 seconds after starting OR
• The unit is in PC Mode OR
• The unit is in Pretrip OR
• There is an active shutdown Alarm.
Defrost may also be initiated automatically at preset
intervals by the system defrost timer or by the defrost
air switch.
The Defrost Mode terminates when the defrost termi-
nation temperature (1DTT) rises higher than 55°F
(12.8°C). Should the defrost cycle not end after a maxi-
mum of 45 minutes the defrost cycle is terminated
automatically. The A00054 – DEFROST NOT COM-
PLETE alarm will be activated.
If the alarm is activated, the system will wait 1.5 hours
of unit running time before attempting an automatic
defrost cycle. Pressing the manual defrost key will
override this mode and start a defrost cycle.
TIP
The Manual Defrost Key can be used at any
time to start a Defrost Cycle as long as the
preceding conditions are met.

mation on DEFROST.
