Defrost Cycle (Low Temperature Models)
The evaporator fin coil is defrosted by an electric defrost heater located on the underside of the coil.
The defrost cycle is initiated and terminated by the controller fitted on the electrical box. This control
not only terminates the defrost cycle, but delays the fan start-up after the defrost cycle to prevent the
residual heat of heater from being blown into the product area.
