5. Defrost Initiation
EvapFM and Defrost icons are on.
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
terminates, Comp icon turns off, Comp de-energizes, and 30-min. DT starts.
Note: If the display module panel is locked, press and hold the "-" button and the power
button until "UnL" appears briefly on the display module.
6. Defrost Termination
Comp icon is on. EvapFM icon flashing.
30-min. DT terminates. 6-hr. DT starts. Comp
icon turns on and Comp energizes. 3-min. Comp run timer starts. 2-min. EvapFM timer
starts, EvapFM icon starts flashing, and EvapFM de-energizes. When 2-min. EvapFM

7. Energy Saving Mode
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.
Note: If DS is activated (door open) before 20-min. ESM timer terminates, ESM timer
resets and 20-min. ESM timer re-starts once CTh cools to setpoint again.
EvapFM ESM Cycle:
• If Comp is de-energized when 20-min. ESM timer terminates, EvapFM de-energizes.
• 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
operates on and off with Comp.
