The mix temperature must be raised above 151_F
(66.1_C) within 90 minutes or the freezer will be locked
in STANDBY, and the cycle failure display will appear.
In the example, the hopper temperature is 140_F
(60_C). The phase shows that the machine is in the
heat phase of the heat treatment cycle.
When the heating phase is complete, the freezer goes
into the holding phase of the cycle. The holding phase
will hold the temperature above 151_F (66.1_C) for a
minimum of 30 minutes.
In this example, the hopper temperature is 151_ F
(66.1_C).
