2.5 MAIN MENU

The main menu is the starting point for all
functions of the Quickchiller. This includes
starting the hold, defrost, and chill cycles; report
printing; and changing the system configuration.
There are four main options shown on the main
menu screen. These options are selected with
control keyboard buttons "A" through "D." The
remaining options are initiated by holding down
a number button for 5 seconds. These options
are used to test the chiller, and to view or
change the configuration of the chiller.

2 . 6 OPERATION WITH FOOD PRODUCT

Stage 1:
Prior to introducing product to the cabinet, the
unit should be operated in the timed chill mode
for thirty minutes. This procedure will reduce
the temperature of the interior components and
the cabinet air sufficiently to be able to accept
hot food products.
Stage 2:
Roll the roll-in cart into the Quickchiller, select
mode and start operation.
Stage 3:
At a factory adjusted set-point the smaller
condensing unit will cycle
larger system to continue the temperature
pull down process.

HOLD:
The labels "UPPER," "MID," and "LOWER" all
refer to the internal food probes. The screen
displays the current temperature of these
probes in either Celsius or Fahrenheit. The
length of time the hold cycle has been active is
shown in the upper right corner of the screen.
2.5.2 O p e n D o o r
If the door is opened while the chiller is in the
hold mode, a buzzer will sound and a warning
message will appear in the display.

A variation of this warning message will
appear in the display when the door is opened
in any cycle; hold, chill, or defrost. The precise
time the door is opened is recorded in memory
and can be obtained on a print-out.
Stage 4:
Upon satisfaction of the Chill Mode selected, the
system will revert to the hold mode.
Stage 5:
Once the system has run through prolonged or
consecutive quick chill cycles, it may be
advisable to place it through a manual defrost.
The system will automatically defrost in the hold
mode — BUT ONLY IN THE HOLD MODE. A
manual defrost can be initiated and, depending
on unit usage, may be necessary to maintain
proper operation.
Adequate spacing must be allowed between
pans for proper air circulation for both the
chilling function and subsequent storage.
