If the Electric to Diesel Auto-Switch Enabled
feature in Guarded Access is set NO then the unit
can also be switched from Diesel mode to Electric

Initiating a Manual Defrost
Cycle
Defrost cycles are usually initiated automatically
based on time or demand. Manual defrost is also
available
Manual defrost is available if the unit is running
and the evaporator coil temperature is less than or
equal to 45 F (7 C).
NOTE: If the Rail Alternate feature is set YES
defrost is allowed with an evaporator coil
temperature less than or equal to 55 F (13 C).
Other features such as door switch settings may
not allow manual defrost under some conditions.
To initiate a manual defrost cycle, press the
Defrost Key (Figure 59).

The display briefly shows [DEFROST],
[PROGRAMMING DEFROST - PLEASE

60).
Figure 60: Defrost Started
The display then shows the Defrost display. The
bar indicator shows approximately how much
time remains to complete the defrost cycle. The
bar indicator shows that the defrost cycle is about
25% complete (Figure 61).
