This display indicates the freezer is operating in 3
different modes. The following i nformation is given:
The left side of the freezer is operating in the
STANDBY mode, and the mix level in the hopper is
OUT. The right side is operating in the WASH and
PUMP modes, and the mix level in the hopper is LOW.
The temperature of the mix in both hoppers is 40_F.
(4.4_C.), and the machine needs to be brush cleaned
on October 31st.

DO NOT draw product or attempt to
disassemble the unit during the HEAT cycle. The
product is hot and under extreme pressure.
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 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.).

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 2
hours, the freezer will lock out.
This example illustrates that the temperature is being
lowered, but has not yet reached the set point.
