in Starting The Diesel Engine.
Initiating a Manual Defrost Cycle
Defrost cycles are usually initiated automatically based on time or demand.
Manual defrost is available if the unit is running and the evaporator coil
temperature is less than or equal to 45°F (7°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 as shown ( Figure
40, p. 42 ).

The display then shows the Defrost display. The bar indicator shows
approximately how much time remains to complete the defrost cycle. The
bar indicator (
Figure 42, p. 43 ) shows that the defrost cycle is about 25%
complete.
