SECTION 6 – ACCESSORY OPERATION
Operation of the Defrost System (DEFR303)
A Defrost System is used to maintain operational temperature below 5ºC. When the
chamber temperature is below 4.5ºC, the defrost system is enabled automatically.
When the chamber temperature is above 4.5ºC (except during a defrost cycle), the
defrost system is disabled automatically.
When the defrost system is enabled (below 4.5ºC), a defrost cycle will occur once
every 12 hours and lasts for about 20 minutes. During the defrost cycle, the chamber
temperature will increase several degrees above set point to melt any ice that has
formed on the evaporator. This temperature ‘spike’ is normal and assures long-term
operation.
During a defrost cycle, the (Info) icon will appear on the status bar.
