a) Automatic Defrost Initiation: EvapFM and Defrost icons are on. EvapFM continues. 

6-hr. DT terminates. 30-min. DT starts. If Comp run time < 3 min., Comp icon and 
Comp continue until 3-min. Comp run timer terminates. Once 3-min. Comp run timer 
terminates, Comp icon turns off, Comp de-energizes, and defrost starts. 

b) Manual Defrost Initiation: EvapFM and Defrost icons are on. To initiate a manual 

defrost, press and hold the "+" button until the defrost icon turns on. EvapFM 
continues. 30-min. DT starts. If Comp run time < 3 min., Comp icon and Comp 
continue until 3-min. Comp run timer terminates. Once 3-min. Comp run timer

ESM initiates during periods of inactivity. Once CTh cools to setpoint, 20-min. ESM timer 

starts. DS must remain engaged without activation (door open) for 20 min. after CTh 
has achieved setpoint for ESM to initiate. Once 20-min. ESM timer terminates, EvapFM 
operates on ESM cycle. See "EvapFM ESM Cycle" below.

• If Comp is energized when 20-min. ESM timer terminates, EvapFM continues and 

cycles off with Comp.

• During ESM Comp off time, EvapFM operation is 1 min. on and 5 min. off. EvapFM
