QUICKCHILLER INTRODUCTION
The Alto-Shaam® Quickchiller
™
is a processing
refrigeration system designed to rapidly and
uniformly cool hot foods for enhanced safety, longer
storage life, and better production efficiency.
The Alto-Shaam® Quickchiller can be effectively
utilized in several types of food service programs:
1. TRADITIONAL COOK-SERVE KITCHENS
Quick-chilling can be used to help streamline
production in operations where foods are
prepared for immediate service. Preparation of
labor intensive entrées can be scheduled for
production the day before service. Quick-
chilling leftovers also provides the ability to use
these items at a later date while maintaining both
safety and product quality.
2. MODIFIED COOK-CHILL OPERATIONS—
where a significant portion of food is cooked for
immediate service; and a smaller portion of
more labor intensive, hot food items are
prepared in advance, chilled, and reheated
when required for service.
3. FULL COOK-CHILL OPERATIONS —
where all hot food production is prepared in
advance of service requirements and held in
refrigerated prepared food inventories. Hot food
preparation takes place over a five-day
production schedule.
The Alto-Shaam Quickchiller produces high-
velocity chilled air which is directed above and
below each pan of food to quickly reduce the
temperature of hot foods from 140°F to 40°F (60°C to
4°C). This high-velocity air removes the insulating
layers of hot, moist heat surrounding hot food
products. As a result, the rate of heat transfer from
the product increases which allows the food to cool
more rapidly.
Rapid reduction in the temperature of hot foods
inhibits the growth of bacteria and provides a safe,
five-day refrigerated storage period from the time of
preparation to the time of service. Enhanced storage
time offers the food service operation considerable
production efficiency. As an example, a daily menu
item is reduced from daily preparation to a two day
a week preparation schedule.
UNDERSTANDING QUICKCHILLER
OPERATION MODES
ALTO-SHAAM quickchiller
™
OPERATION AND PROCEDURE GUIDE
Pg. 1
INTRODUCTION
AUTOMATIC CHILL
This mode provides chill
processing activation and termination
through use of a food probe inserted
into the center of the food.
The cycle is automatically
terminated when the center of the
food reaches 38°F (3°C) as sensed by
the food probe.
HOLD
This mode provides a storage
air temperature of 38°F (3°C) to
hold foods safely upon completion
of chill processing or to keep the
cabinet in a chilled state between
processing cycles.
TIMED CHILL
This mode provides chilling
based on a timed duration.
To protect against product
freezing, the cabinet air sensor may
assume control of chilling until the
selected time has expired. Upon
completion of the timed cycle, the
cabinet automatically reverts to the
hold mode, storing foods safely at
38°F (3°C).
START-UP PROCEDURE
Following electrical installation, the following steps
are necessary to prepare the control for operation.
SET-UP
1. Make certain the main menu (see pg. 3, section 1.0)
appears in the LCD when the breakers are
switched to the ON position. If main menu does
not appear, refer to the start-up procedure located
in the Installation & Maintenance manual.
2. Access the Password screen: Press and hold the
"0" button on the keyboard for a period of 5
seconds. When the Password Entry screen is in
view, enter the password number on the
numerical keyboard.
PASSWORD: 5588744
Following password entry, press "D" on the
keyboard to access the User Setting Menu screen.
If the wrong password number is entered in error,
"Access Denied" will appear in the display. If it
remains in the display longer than 60 seconds, the
locked control panel cover must be opened and
the yellow reset button pressed ONCE. Relock
the control panel and enter the correct password
to gain access to the User Setting Menu screen.
3. Select option "B" and set the correct time and date.
Time must be set in 24 hour format only (military time).
TIME AND DATE MUST BE SET FOR
CHILLER TO OPERATE PROPERLY.
4. Following time and date entry, press "C,"
immediately followed by "D" to return to the Main
Menu screen.
START-UP TEST
1. With the chiller door closed, test the door buzzer
and door switch by entering the hold cycle. Press
"B" on the keyboard when the Main Menu screen
appears on the display. The compressor will
become audible. After a period of 60 seconds, open
the unit door. A buzzer should sound and the
display will prompt the operator to close the door.
2. Close the door and allow the unit to operate for
approximately 10 minutes. Verify the operating
time with the timer which appears in the upper
right-hand corner of the Hold Mode display screen.
If the timer does not indicate the correct amount of
time, begin the SET-UP procedure once again.
3. With the food probes remaining in the
appropriate door holder (no product) verify a
decrease of the temperatures appearing in the
display. The temperatures displayed should start
at the approximate room temperature and
decrease from that point. If any of the
temperatures displayed are above 120°F (49°C),
considerably above normal room temperature,
contact the Alto-Shaam Service Department.
4. Following the 10 minute test operation period,
press "D" on the keyboard to exit the hold mode.
Open the unit door and make certain the interior
walls of the unit are cold.

The Alto-Shaam®
Quickchiller™ includes a
microprocessor control
panel which utilizes a
menu screen to guide the
operator through all
operation mode sequences.
1.0 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."
MAIN MENU SCREEN
2.0 AUTO CHILL MODE
To view the chill menu, press "A" on the
control keyboard.
CHILL MENU SCREEN
To begin the Automatic Chill cycle, press "A" again or
press "D" to cancel and return to the main menu.
When "A" is pressed, the labels "UPPER," "MID," and
"LOWER" appear on the screen. These labels correspond
to the temperature of the food probe(s). "CHILL" also
appears on the screen and indicates the temperature of the
air inside the chiller. The chiller will now begin to
decrease the air temperature until the probes reach chill
set-point.
The operation of the chiller in the Automatic Chill
cycle is dependent on the internal temperature of the
food, therefore, the food probes MUST be used for auto-
chilling. This is the only mode which absolutely requires
the use of the probes.
Whenever a probe chill set-point temperature is
reached, a buzzer will sound and the display
corresponding with the probe position will indicate
"MUTE=A," "MUTE=B," or "MUTE=C." The buzzer
will continue to sound for a period of sixty seconds
or can be stopped by the operator by pressing the
corresponding probe position letter on the control
keyboard. When the buzzer stops, the screen
indicates (DONE) on the corresponding probe
position line.
AUTOMATIC CHILLING SCREEN
(UPPER & MIDDLE PROBES AT CHILL SET POINT)
After all three probes reach set-point, a buzzer will
sound and the last line of the screen will indicate
"HOLD=D." The buzzer will continue to sound for a
period of sixty seconds or can be stopped by the operator
by pressing "D" on the control keyboard.
AUTOMATIC CHILLING SCREEN
(ALL PROBE CHILL SET-POINTS REACHED)
Following the sixty second buzzer or immediately
after the operator presses "D" on the control keyboard, the
Quickchiller will automatically enter the hold mode.

During the hold or chill cycles, it is
normal for the evaporator fans to
periodically cycle
ON and OFF. The
fans will deactivate when the coil
temperature is greater than 60°F
(16°C) and activate when the coil
temperature drops below 30°F (-1°C).

4.2 Auto-Defrost
During the hold mode, the chiller may
automatically enter an Auto-Defrost cycle. This
occurs after the chiller has been holding at least 15
minutes and after the fans have been running for a
cumulative time period of at least 6 hours. During
an Auto-Defrost, the display will show the word
"DEFRSTNG" and a defrost timer will be added to
the display.
AUTO-DEFROST SCREEN
The defrost timer initially begins with a 20
minute time period and counts down to zero. When
it reaches zero, the defrost cycle is terminated. The
defrost heaters will shut off if the temperature of the
coil(s) increases to 16°C (60°F). The defrost time can
be altered by the operator if required. (See the User
Set-Up section for more information.)
To cancel an Auto-Defrost cycle, press "D" while
the defrost cycle is in progress. The chiller will
revert to the Hold Mode, however; because defrost
was not allowed to complete the cycle, the next
Auto-Defrost will begin in one-fourth of the normal
time between cycles.
EXAMPLE: 6 hours ÷ 4 = 1 hour, 30 minutes
If Auto-Defrost completes a full cycle, the next defrost
will occur in 6 hours (factory default).
NOTE: The defrost time period (20 minutes) and the
interval between auto-defrosts (6 hours) are
preset at the factory. If necessary, each of
these settings can be adjusted by the operator.
(See the User Set-Up section for more information.)

AUTO-DEFROST DEPENDS ON THE
FOLLOWING CHILLER CONDITIONS:
1. The fans must be engaged for a cumulative
time period of at least 6 hours (factory default).
2. The chiller must be in the hold cycle and must
be holding for a minimum of 15 minutes.
3. The cabinet air temperature must not be more
than 2°C higher than the hold set-point.
5.0 DEFROST MODE
To initiate a manual defrost cycle, press "C" on the
keyboard when the Main Menu screen is displayed.
MAIN MENU SCREEN
The chiller will display a Defrost Start screen.
Press "C" to start the manual defrost cycle or press "D"
to cancel and return to the main menu screen.
DEFROST CYCLE START SCREEN
If "C" is pressed, a Defrost Cycle screen will appear
in the display.
DEFROST CYCLE SCREEN
The manual defrost cycle automatically terminates
when the 20 minute time period has expired.
Following termination of the manual defrost cycle, the
chiller does not default to Hold Mode. Control Mode
selection is required.
5.1 Manual Defrost Message
The Quickchiller keeps track of how long the fans
and compressors have been running. The chiller uses
this information to determine if defrosting is necessary.
If a defrost is overdue but the chiller does not have the
occasion to apply a normal Auto-Defrost cycle, the
screen will display a "Please Defrost Unit" message.
DEFROST NEEDED SCREEN
The "Please Defrost Unit!" message will be
displayed alternately with the main menu, each for a
period of 3 seconds, and will continue until a
successful defrost has been completed.
If the operator disregards the defrost message and
enters the chill or hold mode, an alternate screen will
be displayed and the defrost required message will no
longer appear. For proper operation of the chiller,
however, a defrost is still required. The "Please Defrost
Unit!" message will reappear whenever the Main Menu
screen is displayed or until a full defrost is
accomplished.

cabinet air sensor during all holding and chilling
cycles. These temperatures are stored in internal
memory in report form. The report shows the time
and date the hold or chill cycle starts and ends, along
with the time of day each temperature sample is
recorded. Chiller memory is sufficient to hold up to 12
reports. The extended memory of the Quickchiller
allows the operator to print chill reports daily such as
each morning for the previous day activity. If the
memory is full when a new hold or chill cycle is
started, the oldest report is deleted to gain sufficient
memory for the most current report.
The rate at which temperature samples are
recorded to memory are factory set at 5 minute
intervals. At 5 minute intervals between samples, a
report will record for 25 hours with up to 300 samples
written to each report. Once this limit is reached, no
additional sample temperatures will be recorded.
(See the User Set-Up section for changing the
temperature sample time.)
6.1 Power Failures
If the chiller loses power during a hold or chill
cycle, it writes a message to the report indicating power
was disrupted along with the time of the power failure.
The power failure message counts as one sample of
the 300 maximum per report. After power is restored,
the chiller reverts to the last cycle in progress and
continues the same report.
As long as the chiller is connected to the power
source all reports will remain in memory. In the event
the chiller is disconnected from the power source, a
rechargeable internal battery will retain the report in
memory for approximately 14 days. The internal
battery is automatically recharged when the chiller is
activated and will come up to full charge in 30 hours.
6.2 Opening the Door
If the chiller door is opened during the hold or
chill cycle, it writes a message to the report indicating
the time the door was opened. This message counts as
one sample in the report.
The display indicates a warning message in all
cycles and a buzzer will sound until the door is closed.
6.3 Report Selection
Reports can be viewed on-screen or can be printed.
To access the report function, press “D” on the
keyboard when the Main Menu screen is displayed.
MAIN MENU SCREEN
The Report Selection display will usually indicate
the most current data entries, however, all reports in

8.0 SPECIAL FEATURES
The Alto-Shaam® Quickchiller has been provided
with additional features which are not obvious from
the choices appearing on the main menu. These
features are accessed by changing the position of a
dip-switch or by pressing and holding a specified
keyboard number.
8.1 Dip-Switch Access Features
A five-position
dip-switch is located
behind the locked
control panel on the
CPU board. The dip-
switch is read by the
software each time
the main menu is
entered. Changing the
settings while at the
main menu will not
effect a change until the
main menu is exited
and reentered.
When taking
advantage of the
special feature
program options,
we strongly
recommend
individuals with
an electronics
background to
properly locate and
change dip-switch
position.
8.1.1 ENGLISH TO SPANISH
Dip-Switch #1: OFF = English
ON = Spanish
A position change to
ON allows the operator to
convert all viewing screens from English to Spanish.
With a conversion to Spanish, viewing screens for
User Set-Up which includes the Password Entry
screen and all subsequent screens within the
configuration change program remain in English. In
addition, all data sent to the printer will only
appear in English.
8.1.2 ON-LINE PRINTING
Dip-Switch #4: OFF = Normal Operation
ON = On-line Printing
A position change to ON enables the chiller to
output a printed report during a hold or chill mode
rather than waiting for the cycle to complete. An
on-line printed report is nearly identical to a report
printed from the Main Menu screen at the end of a
cycle, however, the "end time" and "hold duration"
are excluded from the report.
On-Line Printed Example
The letter "A" following the printed sample time
signifies the chiller was in the Auto-Chill mode, just
as "H" would signify Hold or "T" Timed-Chill.
Unlike standard reports with a 300 maximum
sample limit, on-line printing can contain an
unlimited amount of samples. Printing will
continue until it is terminated by the operator. An
on-line printed report also indicates the amount of
cooling power used at each sample time point.
Enabling the on-line printing option will result
in a minor delay between the time a operator selects
a screen function and the actual onset of the
function. This delay occurs because the chiller is
engaged in sending data to the printer and should
be considered a normal operating condition.
If On-Line Printing is enabled without a printer
connected to the chiller, the chiller will function as
if a printer was attached. The data sent to the
printer will terminate at the printer connection
point and will subsequently be lost since the chiller
is unable to detect a printer.

9.0 PRINTER HARDWARE NOTES
SERIAL PRINTER: The printer MUST have an internal
buffer of at least 1K bytes. Since the
printer must be able to maintain the
same pace as the control, and there is
no printer handshaking, printers
with smaller buffers simply cannot
keep up.
The printer must also conform to RS-
232 standards and must be able to
print using only the TX and GND
lines (i.e., without hardware
handshaking or software hand-
shaking (XON/XOFF). Nearly all
serial printers can print without
handshaking. The printer should be
connected to the control with a
NULL serial cable.
RECOMMENDED:
Alto-Shaam PN# 14218
Star Micronics PN# DP-8340 FM
PARALLEL
PRINTER: Any EPSON, IBM PRO-PRINTER
or compatible is acceptable. The
internal buffer should be at least
1K byte. Most of the newer
printers have at least this amount
or more. A standard printer cable
is required. It is not necessary to
use a printer with 24 pins or special
graphic capabilities.
RECOMMENDED:
Alto-Shaam PN# 14709
SET-UP AND CABLING INSTRUCTIONS:
1. Confirm the gray ribbon cable, originating from the
relay board, is connected to the J7 I/O connector.
2. Confirm the 3-wire cable assembly originating from
the sliding door connection part is connected to the
J29 terminal.
3. With Star Micronics printer model DP8340 power
OFF, confirm only the #2 dip switch (left side of
printer) is down.
4. Confirm the Quickchiller CPU board dip switch
positions are as follows: #4 IS DOWN; #5 IS UP.
5. Confirm the Quickchiller CPU board WP/OFF shunt
is to WP side.

UNDERSTANDING
QUICKCHILLER OPERATION MODES
• AUTOMATIC CHILL
This mode provides chill processing activation and
termination through use of a food probe inserted
into the center of the food.
The cycle is automatically terminated when the
center of the food reaches chill set point temperature.
• HOLD
This mode provides a storage air temperature of
38°F (3°C) to hold foods safely upon completion of
chill processing or to keep the cabinet in a chilled
state between processing cycles.
• TIMED CHILL
This mode provides chill processing cycle activation
and termination based on a timed cycle selected by
the operator.
Upon completion of the timed cycle, the cabinet
automatically reverts to the hold mode, storing
foods safely at 38°F (3°C).
INITIAL QUICKCHILLER OPERATION
PRECHILLING THE CABINET
The Quickchiller should be prechilled prior to
placing food into the cabinet. In models equipped
with a roll-in cart (trolley), always maintain an empty
food cart inside the chiller when prechilling. This
eliminates air loss through the bottom of the chiller
cabinet door.
ALLOW 40 MINUTES PRECHILL TIME.
NOTE: During the initial cooling of the
Quickchiller, an evaporator fan delay
system will prevent the chilling fans
from engaging until the evaporator coil
temperature is below 30°F (-1°C).
Conversely, when the system is turned
OFF, the evaporator fan(s) will continue
to operate until the evaporator coil
temperature is above 60°F (15°C).
UNDERSTANDING
THE CHILL PROCESSING CYCLE
The Alto-Shaam Quickchiller uses high velocity
air circulation to remove heat from prepared
foods, rapidly reducing temperatures through the
Danger Zone. Air circulation is directed from
right and left in each Quickchiller model. Side-to-
side air circulation insures even and complete
cooling of all pans loaded in the unit.
When placed in the cold air of the chiller, high
velocity air sweeping across the pans removes
insulating layers of warm moist air that surrounds
hot products. Removing these insulating layers of
warm, moist air increases the rate of heat transfer
from the food which results in rapid product cooling.
Because the basic performance of the
Quickchiller relies on high velocity air movement
across the containers of food, it is important to load
the food by placing pans directly in the pan slides,
using the slides to support the edges of 12" x 20"
steam table pans (GN 1/1). For 18" x 26" sheet pans;
12" x 10" steam table pans (GN 1/2); loaf pans;
entree plates; and other small containers, use a wire
rack or shelf for pan support.
CAUTION
NEVER STACK PANS DIRECTLY ON TOP
OF EACH OTHER. THIS WILL BLOCK
AIR FLOW AND INCREASE CHILL
PROCESSING TIME.
To maintain sanitation control when loading
the Quickchiller, foods should be above
140°F (60°C) and should be tightly covered.
CAUTION
ADEQUATE SPACING MUST BE
ALLOWED BETWEEN PANS FOR
PROPER AIR CIRCULATION FOR
BOTH THE CHILLING FUNCTION
AND SUBSEQUENT STORAGE.
