INSTALLATION
REMOVAL OF REDUNDANT APPLIANCES
Refrigeration appliances contain refrigerant and
gases in their insulation and must be disposed of
professionally by a licensed waste management
contractor.
Please ensure that old or redundant refrigeration
appliances are disposed of safely and legally. It is
recommended that doors are removed prior to
disposal in order to ensure safety.
UNPACKING
The Roll-in Blast Chillers/Chiller Freezers and
Freezers are supplied modular form on pallets and
require assembly on site. Please see additional
manual on assembly
Remove all external and interior packing and
accessories. Ensure all such material is disposed
of safely.
Check that no damage has occurred to the
appliance, the tubing of the refrigeration system,
power cable and plug top during transit. If damage
has occurred do not use the appliance.
The appliance should be installed in a well ventilated
room on a at and level oor.
PROTECTIVE COATING
The polished stainless steel surfaces are protected
during manufacturing and transport by an adhesive
plastic coating.
This should be removed prior to placing your
appliance into use. Carefully peel away to reveal
the polished stainless steel surface. Care should be
taken to ensure that no adhesive residue remains
on the surface. Any stubborn or tough adhesive
marks can be removed by following the advice on
Page 11.
VENTILATION
Refrigerators generate a considerable amount of
heat and, if operated in a small unventilated room
will quickly cause the room temperature to become
excessive. This could cause the motor to overheat
and possibly damage the compressor. At the very
least, such an installation will cause the unit to use
an excessive amount of electricity.
In addition to ventilation in a room, please ensure
that cabinets with top-mounted systems (WBC/
WBCF50, WBC70 & WTBC70) have 500mm
clearance between the cabinet top and the ceiling
for engineer access and ventilation. For all other
cabinets, please ensure a minimum clearance
of 50mm is provided around the unit to ensure
ecient and eective performance.
Roof mounted pod storage refrigeration systems
require adequate ventilation as well.
LEVELLING (CASTORS/FEET)
The Reach-in Blast Chillers / Chiller Freezers should
stand level to ensure the correct operation of self-
closing doors and proper drainage of condensate
from the evaporator.
Models tted with castors are non-adjustable.
Therefore a level platform / oor should be
provided where the appliance is to be located.
Where swivel and brake castors are tted and it
has been positioned, please ensure its brakes have
been activated by pressing the metal bar down.
Remember to release the brakes before trying to
move it.
On models tted with legs, levelling may be achieved
by adjusting the bottom section. For marine
specication models with anged feet for deck and
bulkhead xing, installation should be carried out by
a specialist marine company.
MAINS CONNECTION
Commercial kitchens and foodservice areas
are environments where electrical appliances
may be located close to liquids, or operate
in and around damp conditions or where
restricted movement for installation and
service is evident.
Great care must be exercised at all times when
installing, operating or servicing this appliance.
For appliances tted with a moulded plug, for safety
ensure that the mains power cable is extended free
from the refrigeration system and cabinet, to avoid
entanglement. If a plug or mains cable requires
replacement, contact the Williams Spares Oce on
[phone].
The installation of a xed appliance and periodic
inspection should only be undertaken by a qualied,
skilled and competent electrician; and connected
to the correct power supply suitable for the load as
stipulated by the appliance data label.
Do not block vents by stacking boxes on top
or in front of the unit as this could aect
performance and give rise to safety risk.
INSTALLATION

5
The electrical installation and connections should
meet the necessary requirements to the local
electrical wiring regulations and any electrical safety
guidelines and use the following:
• Copper conductors only, for mains supply wiring
• Use conductors with a minimum cross-sectional
area (CSA) of 12AWG (4.00mm2)
• Suitable overcurrent protective device (fuse/
circuit breaker) with a 10kA or greater breaking
capacity
*WARNING! Risk of electric shock.
Some conductors remain live when
the equipment is in standby.
Safely isolate from the power
supply before servicing.
* Applicable to the U.S.A cabinets only.
All appliances rely upon a suitable connection to
earth to ensure safe operation. If in doubt, contact
a qualied, skilled and competent electrician before
using the appliance.
The equipment must be connected to the correct
mains power supply as stipulated by the appliance
data label and local authority regulations.
We recommend:-
• Supplementary electrical protection with
the use of a residual current device (RCD)
• Fixed wiring appliances incorporate a
switch disconnector for purposes of
safe isolation to meet their specication
requirements of IEC 60947
WBC/WBCF10 & 20 are single phase and come
tted with a moulded plug for safety and must be
earthed. We recommend that should the plug
or cable fail contact Williams Spares Oce for a
replacement part.
WBC/WBCF30 & 40 are single phase. They should
be connected to a 16A single phase supply by a
qualied refrigeration engineer or electrician.
WBC/WBCF50, WBC70 & WTBC70 are 3 phase.
They should be connected to a 16A 3 phase and
neutral power supply. This should be carried out by
a qualied refrigeration engineer or electrician.
WBC40 RN should be connected to a 16A 3 phase
(no neutral) by a qualied refrigeration engineer or
electrician.
If the appliance has been laid on its back
or tipped, DO NOT switch on immediately.
Leave in an upright position for at least 3
hours before switching on.
CONNECTION TO A MAIN DRAIN
All models (except WBC/WBCF50, WBC70,
WBC40RN & WTBC70) feature automatic
evaporation so no drain is required.
WBC/WBCF50, WBC70, WBC40RN & WTBC70
requires the condensate drain pipe to be connected
to a suitable 19mm waste pipe or larger ‘P’ trap or
routing to an open oor drain. (This can be found at
the base of the cabinet rear).
ADJUSTABLE TROLLEY GUIDES (WTBC70)
The WTBC70 comes with 1 set of adjustable trolley
guides.
Depending on the required trolley these should
be tted either to the inside (Lainox) or outside
(Rational) set of holes on the underside of the
cabinet.
INSTALLATION

INSTALLATION
Using the screws that are tted to the underside of
the cabinet, slide the guide on using the key hole
slot, then fully tighten the screws.
Once in place, insert the retaining screw at the front
of each guide.
SHELF/SLIDE FITTING
When positioning slides on
standard cabinets and
counters, present slide to
racking by holding it in the
opposite hand to the side of
the cabinet to that which
they are to be applied.
Present the slide at a 45°
angle (See Figure 1). When in
place, let slide drop into
position to create a
horizontal ledge on which
the shelves will sit.
LOADING / SHELF DISTRIBUTION
Before loading, allow the appliance to reach its
normal operating temperature.
The maximum temperature of product entering
the appliance must not exceed +90°C (194°F).
Regulations state that product should be placed in
the appliance within 30 minutes from completion of
cooking.
The packaging of food and the way in which it is
loaded or placed within the equipment can have
a signicant eect 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 or freezing batch. (Maximum food
thickness 50mm).
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 gastronorm
tray or similar. 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, When blast freezing bear in
mind how easy the nished product will be to thaw.
Always load your machine in such a way that it is
possible for the cold air to contact all side 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 facility. Unless it is unavoidable do not open
the door of the appliance whilst the blast cycle is
engaged.
When loading the appliance / trolley please ensure
the load is equally distributed throughout the
appliance and ensure air can circulate around and
through stored products.
STORAGE TIMES
Chilled foods can be stored for up to 5 days at
between 0°C (32°F) and +3°C (37°F).
Frozen foods can be stored for longer periods, in
general for up to 8 weeks without loss of nutrients
or palatability. Beyond 8 weeks those foods with a
high fat content may display some signs of rancidity.
Nevertheless, some other foods can be stored for
periods longer than 8 weeks.
Frozen food must be stored at between -18°C (0°F)
and -22°C (-8°F) or below.
Important: Once thawed, frozen food should
not be re-frozen.

BLAST CHILLER (WBC)
BLAST CHILLER FREEZER (WBCF)
BLAST CHILLER (WMBC)
Principles of Operation
Williams Blast Chillers / Chiller Freezers / Blast
Freezers have been designed to quickly reduce
the temperature of food in accordance with the
Department of Health Guidelines on the chilling and
freezing of cooked foods. All operators should be
conversant with the latest European Food Safety
Legislation.
Further information is also contained in the
Williams Guide to Cook Chill which is available from
the Williams Marketing Department +44 (0)1553
817000.
Fast temperature reduction is not brought about
by placing the food in a very cold cabinet like a
deep freeze coldroom for example. This would
only dry the food badly and would take a very long
time to reduce its temperature to the required level
increasing the risk to food safety. The secret of fast
temperature reduction is in delivering the correct
blast of air and ensuring correct and unobstructed
horizontal air ow inside the cabinet.
Williams range of Blast Chillers feature the option of
soft and hard facility on blast chill oering exibility
and ensures food stays in prime condition whether
it is delicate pastries or sh, or heavier items such as
lasagne and meat casseroles.
Exceptions: depending on the density types and
sizes of the portions the chiller / freezer might not
be capable of achieving the required guidelines
therefore the load and / or depth of the food layers
should be reduced. You may nd it necessary,
therefore, to experiment with dierent amounts
of food and loading methods in order to achieve
the optimum performance with your blast chiller /
freezer.
Operation of Blast Chillers / Chiller Freezers
Initially the appliance will be in a standby mode,
shown by 3 dashes (---) in both display windows.
The cabinet needs to have run at least half an hour
before being used.
All Blast Chillers have 3 basic modes:
1. Blast Chill Soft +1°C (34°F)
2. Blast Chill Hard -10°C (14°F)
3. Default Storage +1°C (34°F) to +3°C (37°F)
(dependant on selected cycle)
Combination Blast Chiller Freezers have 2 further
modes:
4. Freezer Storage -18°C (0°F) to -22°C (-8°F)
5. Blast Freeze -25°C (-13°F)
Dedicated Blast Freezers have the same two modes.
Store 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.

CONTROLLER
The type of store mode is indicated under button
. Press button to select the right storage
temperature if using the combination chiller freezer.
From 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 or freeze
cycle by pressing
3. Initiate a manual defrost by pressing and
holding both and for 3 seconds
4. Pressing during a probe cycle will cause all
enabled food probes and their respective
temperatures can be displayed in a scrolling
process (each probe’s information is displayed
for 4 seconds):
5. Further 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.
Function 5 can be initiated in any operating mode
except in standby.
Blast Chill or Freeze Programming
Check that the chiller is operating at storage
temperature. Load the products for chilling/freezing
- refer to the previous loading information. If using,
place the food probe into the centre of the product
to be chilled. Then programme the cycle as follows:
1. By pressing button to select the desired
type of blast - soft blast (4 blocks), hard blast (2
blocks) or freeze (single block). (Freeze option on
Blast Chiller Freezer models only).
2. By pressing button select timer for the
desired duration either 90 or if blast freezing 240
minutes or probe (temperature controlled cycle).
3. By pressing button start the blast chill or
freeze cycle.
If you are unhappy with your selection press the
button to cancel your selections and the appliance
will revert back to store mode. Pressing this button
will stop the blast chiller 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
enter the blast set mode.
When a Blast Cycle has been initiated, the following
will be displayed:
The blast cycle is ended under normal operation by:
• Reaching the required temperature +3°C (37°F)
or -18°C (0°F).
• 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
• Food 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.
• Mains failure longer than 3 minutes

Continuous Blast (USA Models Option Only)
The LED’s beneath the right-hand display window
indicate whether or not each enabled food probe
has achieved the target temperature (temperature
setpoint). If the LED is illuminated, the food probe
relevant to that LED is yet to reach the target
temperature. Thus, if it is not illuminated, the food
probe relevant to that LED is yet to reach the target
temperature. Thus, if it is not illuminated, that food
probe has achieved the target temperature. The
LED will illuminate once more when the temperature
relevant to that probe reaches 10°C (10°F) above
the target temperature (for example: inserted into
hot food).
At the end of a cycle, an audible alarm will sound for
10 seconds with the left window displaying the time
and in the right window the LED’s will start ashing.
Defrost
A defrost cycle is automatically instigated at the end
of each blast chill cycle to clear any ice from the
evaporator ready 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.
During a defrost the display windows will indicate
the following:
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 nished 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 aect 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:
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.
When a probe is at fault then the windows will
display as follows:
T1 - air probe T4 - Food Probe 1
T2 - evaporator T5 - Food Probe 2
T3 - auxiliary probe
(not applicable)
T6 - Food Probe 3
Alarm codes that are displayed are:
E1 - HP/LP fault (not applicable)
E2 - Over temperature
E3 - Mains failure longer than 3 minutes
Hi - High temperature
Lo - Low temperature
or - Probe over range failure
Alarms during Blast Cycles
If the blast chill cycle has been terminated as a result
causing an alarm, a defrost cycle will automatically
be initiated. However, if an alarm occurs such as
evaporator probe (T2) fault then the blast chill cycle
will continue.

Airow
In the unlikely event that
your blast chiller is taking
longer to perform its chilling
cycle, ensure that the airow
is operating in the correct
way. 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
used 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 over-riding
the controller’s logic when air probe (T1) fails,
thus preserving the food until a service engineer
intervenes. 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 o and so on.
High 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 tted
then terminals L2 and L3 have to be linked.
THERMOSTATS AND 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 the chill
thermostats and freeze thermostats.
NB: The soft blast chill thermostat is a “delta”
(oating) value to be added to the store chill
thermostat set point to achieve the nal soft blast
chill thermostat set point.
Example: If the store chill thermostat is set to +3°C
(37°F), and the soft chill value is set to -2°C (34°F),
then the achieved soft blast thermostat will be +1°C
(28°F).
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 oset
parameter to compensate for temperature drift and
manufacturing tolerances of the probes.
Do not submerge probe handles into liquids.
MISCELLANEOUS FUNCTIONALITY
Condenser Clean
The condenser will require cleaning from time to
time. A timer parameter “Acc” is used to log the
compressor run time (units of weeks). After the
preset period a warning is announced.
For the purpose of notifying the user, a designated
condenser clean button and LED are used. A
ashing red LED signies that the condenser
requires cleaning. Pressing and holding the button
for 3 seconds will reset the timer and the LED will
stop ashing.
CONTROLLER

11
Display Slow Down
The purpose of applying a “display slow down” is
to delay the real time temperature being displayed
on the controllers front control interface. This will
avoid rapid uctuations 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 simulate 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.

APPLIANCE ROUTINE MAINTENANCE / CLEANING
ROUTINE MAINTENANCE
Safely disconnect the appliance from the
power supply before cleaning, servicing or
undertaking general maintenance.
We recommend that you undertake regular
preventative maintenance using a qualied
service provider in order to get the best from your
equipment.
Ensure you check the sealant between panels on
an annual basis and clean and replace the sealant if
required as damaged sealant can aect the hygiene,
performance and eciency of your equipment.
CLEANING
Always wear appropriate personal protective
equipment (PPE) when cleaning the appliance. Care
should be taken for parts with possible sharp edges.
Stainless steel is naturally corrosion-proof and
needs no additional protective coating to maintain
its gloss and usability for a long time.
Abrasive or corrosive cleaning agents should never
be used. These can damage surfaces and cause
corrosion. They include:
• Cleaners containing chloride;
• Bleaches containing hypochlorite (if accidentally
spilled on stainless steel, rinse o with water
immediately and thoroughly);
• Silver polish
If the cabinet exterior is looked after correctly it will
retain an “as new” nish for many years. A damp
cloth is usually sucient for wiping away light dirt,
food debris and nger marks and normal day to day
cleaning should be carried out with a soft cloth and
soapy water.
White PVC coated panels are more durable, but still
should be cleaned with a soft cloth and soapy water.
Dry thoroughly afterwards and where possible
remove all racking, shelving and drawer ttings to
aid the process.
Kitchen fats, oil and greases can also cause brown
spots or stainng to appear on the stainless steel
surface.
For stainless steel with visible polishing grains,
clean the steel with the grain - not against the grain.
When water has been used for leaning or rinsing,
wipe the surface dry to prevent water from drying
and forming watermarks, especially in areas with
hard water. Avoid this type of watermark by using
distilled water.
For tougher spots, creamy polishes like CIF original
cream can be eective. Light pressure should be
used when cleaning with the grain. The cleaning
process should be repeated in order to prevent any
dirt becoming lodged in the surface grain again.
CIF original cream cleaner can also be used
for wiping o water spots and can alleviate
discoloration. Remove this type of residue by rinsing
with clean, preferably distilled water and wipe away
any remaining streaks of polish or watermarks.
Tough grease or oil marks can also be removed
using denatured alcohol or acetone. There is no risk
of corroding stainless steel by using such solvents.
For ease of use limit the amount of solvent used.
Wash more than once using a pure solvent on a
clean soft rag until all traces of the greasy residue
are removed.
Specialist Stainless Steel Cleaners - Non food
contact surfaces only
Innosoft B570 is a special deep cleaner that is
suitable for the intensive cleaning of contaminated
stainless steel surfaces, and removes stains and
oxides in a single operation.
Innoclean B580 completely removes any residues
left after the use of Innosoft B570 and passivates
the surface which helps to prevent further
corrosion.

supports by grasping rmly in the centre and lifting
slightly. Turn the shelf support towards the interior
of the cabinet by pushing it in the centre as you
twist the support through 90°. The shelf support
will be released. (NB: the supports are designed
to be anti-tilt and you may therefore experience
some resistance at rst which will be overcome with
practice). When all shelves have been removed,
remove the racking by lifting up and over the nylon
retaining blocks.
CONDENSER CLEANING
(Only applicable to Air Cooled Units)
Regular maintenance should be carried out on a
regular basis by competent / trained personnel. The
condenser is part of the refrigeration unit and is
located in the unit compartment.
Brush ns vertically with a sti brush, taking care
not to damage them or to push dirt / dust further in,
and then vacuum away.
To cancel the ashing LED, press and hold for 3
seconds.
If there are further grease deposits still remaining
on the condenser call your Service Provider to carry
out a full service.
Note: Non-compliance may invalidate your
Warranty.
REMOVING THE UNIT COVER
Remove the screws in the top and bottom edge of
the unit cover and pull the unit cover away from the
unit and retaining clips.
CLEANING / REPLACING THE GASKET
Door gaskets should be checked and cleaned
regularly and replaced if damaged. To clean the
gasket, wipe with warm soapy water and a soft cloth,
ensuring it is completely dry before closing the door.
DO NOT use a sharp knife to clean or scrape the
gasket. Damaged gaskets do not seal correctly and
can increase the amount of electricity consumed,
seriously aecting the eciency and performance of
the appliance.
Damaged gaskets are easily
replaced. Simply pull out the
existing part and push the new
gasket into the channel (gasket
retainer) at the centre and
work along, pushing gasket into
channel.
EVAPORATOR/DRAINLINE
Inspect periodically to ensure the drain hole is not
blocked.
BREAKDOWN
In the event of a breakdown, please contact Williams
Refrigeration or your Service Provider
When calling, please advise model and serial
number. This information can be found on the data
plate inside the appliance. It should also be noted
on the cover of this Manual. Please ensure that all
redundant parts are disposed of safely and legally.
