Defrost Delay Fan
System Mode
At defrost, fans will continue running for several minutes, using stored cooling in the coil. Once the
coil reaches room temp, the fans will stop, and the heaters will turn on and begin the electric defrost.

Fan Delay
System Mode
Coming out of defrost, the LLS relay will be energized, and the coil will pulldown until it reaches 20ºF,
or 2 minutes, before the fans turn on. This allows any moisture on the coil to re-freeze, keeping it from
spraying and forming ice drops on the walk-in’s surfaces.
