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 ( Press Defrost Key).

The display briefly shows [DEFROST], [PROGRAMMING DEFROST - PLEASE WAIT] and then [DEFROST STARTED] ( 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 ( Bar Indicator).
