4. Modes of Operation
The Northwinds blast chiller has 3 different Modes or Cycles of operation.
Automatic: Default Cycle. Fans and refrigeration cool food to 36°F using the Product Probe (inserted in the middle
of the product) to determine when the cycle is complete.

Northwind enters Auto mode.
Defrost: Melts the ice that may have accumulated on the coil, then returns to Auto mode.

Holding: The unit is holding the food until the user removes it from the blast chiller. The air temperature is kept
below 45°F.
