Models H62 & H63 Important: To the Operator
The following displays pertain to the HEAT cycle:
A System Alert screen displays an alert and alarm 15
minutes prior to the start of the heat cycle. The alarm
will sound and show on the display. The alarm will
sound until the SEL key is pressed to clear the fault.
This feature allows the operator time to make sure the
freezer is in AUTO or STANDBY, and has the proper
amount of mix in the hopper before the start of the heat
cycle.

While in the heating phase, you will see this display. It
shows the present temperature of the hopper.
MODE: HEAT
PHASE: HEAT
HOPPER: 140.0 F
BRUSH CLEAN ON: MM/DD
During the heating phase, 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 cycl e.
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).
MODE: HEAT
PHASE: HOLD
HOPPER: 151.0 F
BRUSH CLEAN ON: MM/DD
The final phase of the heat treatment cycle is the
cooling phase. Now the freezer must cool the mix
below 41_F(5_C). If the product fails to cool in two
hours, the freezer will lock out.
This example illustrates that the temperature is being
lowered, but has not yet reached the set point.
MODE: HEAT
PHASE: COOL
HOPPER TEMP: 55.0 F
BRUSH CLEAN ON: MM/DD
The entire heat treatment cycle must be completed in
four hours.
When the entire heat cycle has been completed, the
normal display will appear, showing the machine i n the
STANDBY mode. The machine may now be placed in
the AUTO mode or left in the STANDBY mode.
MODE: STANDBY
MIX: OK
HOPPER: 41.0 F
BRUSH CLEAN ON: MM/DD
