#8401 QC-100 INSTALLATION & MAINTENANCE MANUAL PG.9
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.

MAIN MENU SCREEN
2.5.1 Hold Mode
To immediately enter the hold food mode,
press "B" on the keyboard when the Main
Menu screen is displayed.
The unit will activate and the chiller will
bring the cavity temperature within a few
degrees of the hold set-point.
HOLD MODE SCREEN
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 Open Door
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.
DOOR OPEN WARNING SCREEN
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.
2.0 — Control Set-Up and Operation
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 OFF allowing the
larger system to continue the temperature
pull down process.
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.
