RECEIVING S IPMENT
All units are performance tested and thoroughly inspected
prior to shipment. Upon leaving the factory all units are in
perfect condition. During the receipt process, examine the
exterior of the shipment packaging for any signs of rough
handling. If the cabinet is damaged, it should be noted on
the delivery slip or bill or lading and signed. Aclaim must be
filed immediately against the carrier indicating the extent and
estimated cost of damage incurred.
UNPACKING
Remove all external and interior packing and accessories.
Ensure all packaging is disposed of safely.
INSTALLATION
Proper installation is the first step to good operation. We
recommend that your blast chiller be installed by alicensed
commercial refrigeration service company.
Reach-In & Roll-In Cabinets:
The cabinet should stand level to ensure correct operation of
self closing doors and proper drainage of condensate from
the evaporator.
Models fitted with casters are non-adjustable, therefore a
level platform/floor should be provided where the cabinet is
to be located. On models fitted with adjustable legs leveling
may be achieved by adjustment of the bottom section of the
legs.
or top mounted refrigeration systems, please ensure there
is 20” (500mm) between the top of the cabinet and ceiling for
service technician access and ventilation.
If a reach-in cabinet with a self-contained top mounted
refrigeration has been laid on its back or tipped, DO NOT
switch “ON” immediately. Leave the cabinet in the upright
position for at least 12 hours before switching “ON”.
Ventilation
It is essential to ensure that the room in which the
cabinet is installed is adequately ventilated. Refrigerators /
Chillers generate considerable amounts of heat and, if
operated in small unventilated room, especially in warm
weather, this will quickly cause the room temperature to rise.
This could cause the motor to overheat and possibly damage
the windings. At the very least, such an installation will cause
the cabinet to use an excessive amount of electricity.
Locking Casters
When a reach-in cabinet has been placed in a desired
location, please ensure brakes have been placed into the
“lock” position by pressing the metal bar down. Remember
to release the brakes before trying to move the cabinet.
Pan Slides & Shelves:
When positioning the slides, present the slide to the racking
by holding it in the opposite hand to the side of the cabinet
you are installing the slides. Position the slide at a 45°
(degree) angle as shown in Figure 1. Once in place, let the
slide drop into position creating a horizontal ledge on which
pans or shelves will sit.
ELECTRICAL SUPPLY
Wiring should be done by a qualified electrician in
accordance with local electrical codes. All models with the
exception of the WBC110, WMBC175, WMBC220,
WMBC350, WMBC480 & WMBC660 come fitted with a
NEMA plug for safety, and must be grounded. The
WMBC110 and WMBC’s are 3-phase and require connection
to a suitable supply.
Voltage supplied to the cabinet must be between 208
Volts to 230 Volts only; no exceptions! WARRANTY IS
NOT VALID OUTSIDE T E LIMITS OF 230 VOLTS! A
surge protector is highly recommended for added protection.
Note: Please take extra precaution when cabinet is being
supplied voltage to a Delta Circuit).

START-UP
Main Control Breakers
Should the equipment fail to run on initial connection, please
check that all Main Control Breakers (MCBs) are in the “ON”
position at the back of cabinet. Note: The “ON” position is
confirmed by red indicators on the MCBs.
Thermometer
The controller is marked in ahrenheit (° ) or Centigrade (°C)
for the thermometer display. The thermometer should be
checked daily to ensure that the equipment is maintaining the
correct temperature.
If the cabinet is operating at the wrong temperature due to a
default, the cabinet will alarm.
PRINCIPLES OF OPERATION
Williams blast chillers have been designed to quickly reduce
the temperature of food in accordance with Department of
Health guidelines on the chilling of cooked foods. All
operators should be conversant with Department of Health
publication, Chilled and rozen Guidelines on Cook-Chill and
Cook- reeze Catering Systems.
ast temperature reduction is not brought about by placing
the food in a very cold cabinet like a deep freeze. This would
only dry the food badly and take a very long time to reduce
its temperature to the required level. The secret of fast
temperature reduction is in delivering the correct blast of air
and ensuring correct and unobstructed horizontal air flow
inside the cabinet. This is why the equipment has the option
of soft and hard facility on blast chill.
Exceptions: depending on the density types and sizes
of the portions the chiller might not be capable of
achieving the required guidelines, therefore, the load
and/or depth of the food layers should be reduced. You
may find it necessary to experiment with different
amounts of food and loading methods in order to
achieve the optimum performance with your blast chiller.
LOADING AND PACKING
Regulations state that product should be placed in the Blast
Chiller within 30 minutes from completion of cooking. The
packaging of food and the way in which it is loaded or placed
within the apparatus can have a significant effect on the time
within which the temperature can be reduced to the required
level and the amount of food which can be processed in each
chilling batch.
When blast chilling always use metal or foil containers which
are good conductors. Plastic or polyurethane containers
insulate the food from the cold air. When chilling unportioned
food we recommend the use of the appropriate pan that is at
least 2 1/2” (63.5mm) in depth. Likewise, placing lids or
covers on food will also increase the chilling time but may be
of some use when processing some delicate foods to avoid
dehydration.
Always load your machine in such a way that it is possible
for the cold air to contact all sides of the containers. Avoid
stacking containers directly on top of one another as this will
drastically extend the chilling time and take special care not
to block the air ducts.
Always load the machine before selecting the blast cycle.
Unless it is unavoidable do not open the door of the machine
while the blast cycle is engaged.
In the case of roll-in rack models, bumper bars are fitted to
the walls inside the machine. This assists in the correct
positioning of the rack(s) so as to avoid blocking the air flow.
FOOD STORAGE TIME
Chilled foods can be stored for up to 5 days at between 32°
(0°C) and 38° (3°C).
OPERATION OF BLAST C ILLERS
The cabinet is delivered ready to run. Plug (or connect) to the
main power supply and the cabinet is ready for use. Initially
the cabinet will be in standby mode, shown by 3 dashes
( - - -) in both display windows. The cabinet needs to be
pre-chilled (or ran) for at least 30 minutes before being used.
Note: The control systems employed contain no user
serviceable components. Instructions on setting up the con-
trol panel thermostats are available from the manufacturer.
These should only be reset by a qualified service technician.
3 BASIC MODES
Timed Cycle Blast
This is the storage temperature at which food can be held
and the blast chiller automatically switches into this mode at
the end of each cycle. Normal storage temperature range is
34°C (1°C) to 37° (3°C).
Storage Mode
During store mode (with no alarm condition or defrost cycle
running) the left hand window will display the previous blast
cycle duration and the right hand window will display the
store temperature. Some chillers have more than 1 fan
installed; these may not all operate during the storage mode,

giving a reduced air circulation within the chiller.
rom store mode the following functions can be achieved:
1. Go into standby mode by pressing and holding for
3 seconds.
2. Initiate the setting of a blast chill by pressing
3. Initiate a manual defrost by pressing and holding both
and for 3 seconds.
4. Pressing during a probe cycle only will cause all
enabled food probes and their respective temperatures
to be displayed in a scrolling process (each probe’s
information is displayed for 4 seconds):
5. urther pressing during a blast cycle will cause the
displays to revert back to the standard display (ie time and
temperature). Also, cancelling the blast cycle or when the
blast cycle ends the display will revert back to the
standard food probe display.
If no button is pressed for 10 seconds or if is pressed
at any time the cabinet returns to normal store mode.
Continuous Blast Cycle (Reach-in Models Only)
1. Insert the food probe into the desired product.
2. Select the desired temperature and probe blast using
buttons and and confirm your selection with
button
It is possible to cancel at anytime by pressing
3. When the LED goes out for the various food probes, this
indicates that the food probe relevant to that LED
indicator has achieved its target setpoint temperature. If
you wish, remove the relevant food probe from the
product and insert it into a newly introduced product (e.g:
hot food).
The details for a probe that has achieved its target
temperature will be automatically printed and saved onto
the Williams Data Logger.
FP1 03 FP2 02
4. After a short delay, the LED relevant to the probe that
has been reinserted into the newly introduced product
will illuminate once again to indicate that it is attempting
to achieve its target temperature (chilling the product)
once more.
The blast cycle will only end once all food probes have
achieved the target temperature simultaneously.
unction 5 can be initiated in any operating mode except
standby.
BLAST C ILL CYCLE PROGRAMMING
& OPERATION
Check that the chiller is operating and at storage
temperature. Load the products for chilling and refer to the
previous loading information. Place the food probes into the
center of the product to be chilled. Then program the cycle
as follows:
1. By pressing button ‘1’ to select the desired type of blast -
soft blast (4 blocks) or hard blast ( 2 blocks).
2. By pressing button ‘2’ select timer for the desired
duration of 90 minutes,240 minutes or probe
(temperature controlled cycle).
3. By pressing button ‘3’ start the blast chill cycle.
If you are not happy with your selection press the button
to cancel your selections and the cabinet will revert back to
store mode. Pressing this button will stop the blast chiller in
mid cycle and will keep the time displayed following
cancellation until a new blast cycle is programmed - this will
be displayed in the left window.
During defrost or blast cycle, it is not possible to re-enter the
blast set mode.
When a Blast Cycle has been initiated - the following will be
displayed:
Left Display Window - time counting up
Right Display Window - clockwise rotating LEDS signifying
a cycle in progress
00

The blast cycle is ended under normal operation by:
- Reaching the required temperature 37° (+3°C).
- Reaching the end of the designated time (90 or 240
minutes).
- Manual cancellation of the cycle by pressing and
holding for 2 seconds.
- Putting the controller into standby mode by pressing
A blast cycle may also be terminated due to the following
faults or failures:
- Over temperature fault.
- HP/LP fault (if enabled).
- Air probe (T1) failure.
- ood probe failure - terminates the blast cycle if all the
food probes fail. If a 3 probe system is used, and 1 probe
fails, the cycle will continue until the last working probe
reaches temperature.
- Main power failure longer than 3 minutes.
ard or Soft Blast Chill Cycles:
During the ard blast c ill cycle the air temperature inside
the cabinet should go down to approximately 14° (-10°C).
This is for the timed chilling cycle only. Hard blast chill cycles
have the potential to go down to 14° (-10°C) in temperature.
During soft blast c ill cycle the air temperature stays above
32° (0°C). Soft blast chill cycles have the potential to go
down to 34° (1°C) in temperature.
DEFROST
Adefrost cycle is automatic at the end of each blast chill cycle
to clear any ice from the evaporator ready and to prepare for
the next cycle. During storage mode a defrost will be
performed automatically at the factory preset interval of 6
hours. If a blast cycle is cancelled the machine will
automatically initiate a defrost.
Blast Control Panel
During a defrost the display windows will indicate the
following:
Following a blast c ill cycle
An alarm condition is present
- - - will appear in t e left window if power
failure appens during defrost mode for a
duration of 3 minutes or greater
A manual defrost can be initiated by pressing and holding
both and
During the defrost cycle all fans will stop running. When the
defrost cycle is finished the compressor will run for
approximately 60 seconds before the fans cut in. It is safe to
leave products in the cabinet during the defrost cycle; the air
temperature rises slightly but will not affect the products
stored.
After every defrost there is a short period; about 5 minutes
during which a blast cycle cannot be programmed. This short
interval is to allow defrost water to drain away from the
evaporator. At the end of each cycle, a defrost will
automatically clear any ice from the evaporator ready for the
next cycle.
ALARMS
When a fault or adverse operational condition arises, an
audible and visual alarm will be initiated:
General alarm in left window / rig t
window will s ow mode (storage
temperature / blast or defrost)
Mains failure alarm in left window /
rig t window will s ow mode (storage
temperature / defrost; longer t an 3
minutes)
The alarm will sound intermittently. Press to mute the
alarm, the alarm will retrigger if the fault causing the alarm
has not been addressed. The alarm mode will still be
displayed.
More information on the alarm can be displayed during
normal operation by accessing the diagnostic menu by
pressing and holding for 3 seconds.
Left window indicates alarm - t e

Alarm codes that are displayed are:
E1 - HP / LP fault (not applicable)
E2 - Over temperature
E3 - Mains failure longer than 3 minutes
i - High temperature
Lo - Low temperature
or - probe over range failure
ALARMS DURING BLAST C ILL
CYCLES
If the blast chill cycle has been terminated as a result of a
fault causing an alarm, a defrost cycle will automatically be
initiated. However, it an alarm occurs such as evaporator
probe (T2) fault then the blast chill cycle will continue.
CANCELLING ALARMS
Alarms may be cancelled in the following way:
- Putting the cabinet in standby will cancel all alarms
- All alarms can be reset when the fault is removed,
except the mains failure alarm. This alarm remains
displayed until another blast cycle is initiated.
DOOR OPERATED FAN &
CONDENSING UNIT CUT-OUT
SWITC ES (if fitted)
If the door is opened during blast or store mode the
refrigeration unit and evaporator fans will cut out. Both will
restart on closure of door.
Note: it is not advisable to open the door during blast mode
as this will effect cycle.
AIRFLOW
In the unlikely event that your blast
chiller is taking longer to perform its
chilling cycle, ensure that the system
is operating in the correct way. A
possible explanation is that the fan
system has been installed the wrong
way round. As a result the airflow within the blast chiller will
not work as effectively as it should. See the diagram.
COMPLEMENTARY COMPRESSOR
CONTROL
In addition to the conventional operation of the compressor,
the following complementary function applies;
Compressor Rest Time
This function is to ensure that the main compressor does not
run too frequently, and succumb to damage. The parameter
“crt” can be adjusted accordingly. The compressor rest time
does not apply to the beginning of a blast cycle or hot gas
defrost cycle.
Compressor Duty Cycle
This function performs the task of overriding the controller’s
logic when an air probe (T1) fails, thus preserving the food
until a service technician performs service work.
The parameter “cdc” controls the number of forced
compressor cycles per hour.
Example: If set to 5, the compressor (compressor used for
store) will alternate, 5 minutes running, 5 minutes off and so
on.
igh Pressure / Low Pressure Control
To enable the High Pressure / Low Pressure control, the
parameter “PS” must be set to “YES”. Once set the main
compressor relay output is additionally controlled by the High
Pressure / Low Pressure switch (terminals L3 and L2 in
series with terminal L1). If the High Pressure / Low Pressure
input goes open circuit, then the main compressor will stop
running and an alarm “E1” will be displayed.
NB: If the High Pressure / Low Pressure input goes open
circuit during a hot gas defrost, the alarm is ignored. A
subsequent refrigeration cooling cycle will trigger the alarm if
the input stays open circuit.
If a High Pressure / Low Pressure switch is not fitted then
terminals L2 and L3 have to be linked.

T ERMOSTATS & PROBES
Thermostats
The controller can, via the set of thermostat parameters,
control the refrigeration for soft blast chill, hard blast chill and
chill store.
All have independent parameters for set points and the two
hysteresis parameters are for chill thermostats.
NB: The soft blast chill thermostat is a “delta” (floating) value
to be added to the store chill thermostat set point to achieve
the final soft blast chill thermostat set point.
Example: If the store chill thermostat is set to 37° (+3°C)
and the soft chill value is set to 37° (-2°C), then the
achieved soft blast thermostat will be 28° (+1°C).
Probes
The type of probe sensor used for all probes is of the
KTY-81-121 type.
The controller will always require the air (T1) and evaporator
(T2) probes. The number of food probes is selectable from
0 to 3.
If the number of food probes is set to 1, then only the alarm,
diagnostics and temperature controlled blast cycle will be
respective to probe (T4). All other food probes (T5 and T6)
will be ignored. The auxiliary probes (T3) function can be
selected via the parameter “3PM” (default to “no”).
NB: If any probe is enabled but not connected, a probe
failure will arise.
All probes have an offset parameter to compensate for
temperature drift and manufacturing tolerances of the probes.
WILLIAMS DATA LOGGER & T ERMAL
PRINTER
The Williams Data Logger is connected to a thermal printer
which requires a 2.24” (57mm) with a diameter not greater
than 1.57” (40mm) thermal printer paper roll.
The Data Logger retains approximately 7 days worth of data
(depending on usage) by default. This includes all blast
cycles that have been completed or cancelled, defrosts, store
cycles and all alarms. All of the stored data is printed by
pressing and holding the button next to ‘Print’ (1) for 3
seconds. Aconfirmation message ‘Printing’will be displayed.
Please see Page 12 for additional functions and features.
MISCELLANEOUS FUNCTIONALITY
Condenser Clean
The condenser will require cleaning from time to time. Atimer
parameter “Acc” is used to log the compressor run time (units
of weeks). After the preset period a warning is announced.
or the purpose of notifying the user, a designated condenser
clean button and LED are used. Aflashing red LED signifies
that the condenser requires cleaning.
Pressing and holding the button for 3 seconds will reset the
timer and the LED will stop flashing.
Display Slow Down
The purpose of applying a “display slow down” is to delay the
real time temperature being displayed on thecontrollers front
control interface. This will avoid rapid fluctuations displayed
when a door is opened, or when the controller is “hunting”
the instantaneous temperature.
This is achieved by introducing a thermal mass simulation
routine in the software to stimulate a thermal mass inside the
chiller. The parameter “SiM” (default to 3) is used, and an
example being a value of 100 simulates a 0.5 litre (0.1
Gallon) bottle of water.

MAINTENANCE
The cabinets are fully automatic in operation. Cleaning and
loading thermal paper is the only maintenance required.
Read the following topics.
Exterior Cleaning
The exterior of the cabinet is stainless steel and if cared for
correctly will keep is ‘as new’ finish for many years. Normal
day to day cleaning should be carried out with a soft cloth
and soapy water. Always wipe the cabinet vertically in the
same direction as the grain in the stainless steel. While
stainless steel is a very strong and robust material, the
smooth finish can be spoiled by wiping against the grain.
Never use abrasive materials or cleaners, or chemical
cleaners, as they can damage the surface and cause
corrosion. Occasionally, the exterior should be polished with
a good stainless steel polish to protect the surface.
Do not use abrasive cleaners, chemicals or scouring pads
on the control panel. Clean the control panel only with a soft
damp cloth. Avoid excess water on the control panel, and
other areas where electrical components are fitted.
Interior Cleaning
The racking can be removed for easy cleaning (see Figure
2). This should be done on a regular basis with warm water
and a soft cloth, dry thoroughly afterwards. To remove the
racking and shelf supports follow this procedure:
irst remove shelves, then supports by gripping firmly at the
center and lifting slightly. Turn shelf support towards cabinet
interior by pushing at the center as you twist support through
90°. The shelf support will be released. (Note: the supports
are designed to be anti-tilt and some resistance may be
experienced at first. This will be overcome with practice).
When all shelves have been removed, remove the racking
by lifting up and over the nylon retaining blocks.
Door Gasket
Clean the gasket weekly with warm soapy
water and a soft cloth taking care not to
damage it. DO NOT use a sharp knife to
clean or scrape the gasket. Regularly
check the gasket for any damage.
Damage can be caused by striking the
gasket with a sharp object such as the corner of a tray.
Damaged gaskets do not seal correctly and can increase the
amount of electricity consumed, seriously affecting the
efficiency and performance of the cabinet.
Damaged gaskets are easily replaced. To fit a new gasket -
simply pull out the old gasket and push the new gasket into
the channel (gasket retainer) at the center and work along
the gasket pushing it into the channel, continue in the same
way on the other three sides, pushing the corners in last.
Condenser Cleaning
The condenser, which is part of the refrigeration unit, is
located in the unit compartment and requires cleaning
approximately 4 times per year or when the LED indicates.
To clean the condenser, disconnect main power supply
before starting, then brush the fins vertically with a stiff
brush (taking care not to damage the fins or push dirt / dust
further into the condenser coil) and vacuum the dirt / dust
away. Remember to reconnect main power supply when
finished.
TEC NICAL SERVICE &
REPLACEMENT PARTS
Beverage-Air strives to provide excellent customer service
along with quality equipment. To help us better assist you, a
serial number and / or model number must be provided when
contacting the technical service or parts department. The
data plate is located inside the reach-in cabinet on the right
side wall. Roll-in blast chiller data plates are placed on the
exterior of the back panel that supports the controller. All
serial numbers are recorded and kept indefinitely.

10
RULES OF T UMB
1. Pre-chill the cabinet for 30 minutes before you do first load
(this is to remove interior residual heat).
2. Doubling the food thickness triples the pull-down time.
3. Don’t stack food and / or containers on top or alongside or
each other.
4. Covering the food increases pull-down time by 10% -
30%.
5. Pull-down rate initially is about 2° per minute and
approaching final temperature is about 2 minutes per
degree ahrenheit.
6. actors affecting blast chiller pull-down times:
- Entering food temperature (the hotter the initial
temperature, the longer the pull-down time).
- inal food temperature (the colder the final
temperature, the longer the pull-down time).
- ood “thickness” (the greater the distance from
geometric “core” center of food to its surface pull-down
time).
- ood density (the greater the density, the longer the
pull-down time).
- ood thermal conductivity (the lower the conductivity,
the longer the pull-down time).
- ood specific heats (the higher the specific heat, the
longer the pull-down time).
- Container surface area (the smaller the surface area,
the longer the pull-down time).
- Container material (metals are conductors and render
a shorter pull-down time than plastics which are
insulators).
- Covering material (metal preferred instead of plastic
for reasons above).
- Covering method-cover such as aluminium foil or a
“stretch wrap film” placed in direct contact with food
eliminates the “dead air space” between the cover and
the food. Since “dead air space” is an insulator,
elimination of reduction of it shortens pull-down time.
- “Delta T” is temperature difference between the food
and the blast of air. The greater the “Delta T” the
quicker the pull-down time.
- Air velocity (the greater the air velocity across the food,
the faster the pull-down time).
- Amount (weight) of food put in as compared to rated
capacity machine. Exceeding the capacity increases
the pull-down time.
