Proper installation is the first step to operation. We recommend that your refrigerator or

freezer be installed by an authorized Victory Certified Installer.

RECEIVING SHIPMENT

All units are performance tested and thoroughly inspected prior to shipment. Upon leaving the factory,

all units are in perfect condition. Upon receipt, 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 of

lading and signed. A claim 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

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. For marine specification models with flanged feet for

deck fixing and bulkhead fixings, installation should be carried out by a specialist marine company.

For 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 the cabinet 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.

ELECTRICAL SUPPLY

Wiring should be done by a qualified electrician in accordance with local electrical codes. All models,

with the exception of the VBC-100 and all Roll-In VBC’s, come fitted with a NEMA plug for safety and

must be grounded. We recommend that if the plug or cable fail, contact Victory’s parts department for

a replacement part.

The VBC-100 and Roll-In VBC’s are 3-phase and requires connection to a suitable supply.

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.)

INITIAL START-UP ERROR CODES & CHECKS

An “a7” error code (indicating a loss of power) with an audible alarm sound off will always occur

during an initial start-up of a blast chill cabinet. Press the "CANCEL" button (red with✗✗symbol), the

error code and audible alarm will discontinue.

A“Battery Failure Configuration Suspect” error message ticket will always print during an initial

start-up. Do not be alarmed when the error message prints; it is only indicating that the back-up

batteries that hold the cabinets data during a power failure is not fully charged. Full battery charge

should be within 24 hours after start-up.

Check the time and date on the printed tickets. If the ticket has printed an incorrect time and date or

the printer logger paper is not feeding properly, see page 7 for further instruction.

PRINCIPLES OF OPERATION

Victory 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 Frozen Guidelines on Cook-Chill and Cook-Freeze

Catering Systems.

Fast 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 Victory 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°F/0°C and 38°F/+3°C.

OPERATION OF BLAST CHILLERS

Your machine has been set-up at the factory and no further adjustments should be necessary.

Note: The control systems employed are micro-processor based and contain no user

serviceable components. Instructions on setting up the control panel thermostats are available

from the manufacturer. These should only be reset by a qualified service technician.

Normal Storage:

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.

Storage Mode

On some chillers there is more than one fan installed these may not all operate during the storage

mode giving a reduced air circulation within the chiller. All other models have one or more Aerofoil

fans. The unit cycles on the store thermostat, the sensor of which is placed in the air.

Blast Chill Cycle:

All machines have the facility for the operator to use any of the 4 pre-programmed timed cycles and a

probe control blast chilling cycle, with the option of soft or hard blast.

The probe controlled blast cycle functions via the food core probe supplied. The probe monitors the

core temperature of the food and will not permit the blast cycle to stop until the default temperature

(37°F\3°C) is reached. When controlling the cycle with the food probe make certain that the probe or

probes are located in the product before the blast cycle is started.

Pressing the selections automatically adopt the previous settings on the first push. So the repeating

of blast is just pushing buttons 1- 2- 3 & Blast .

Blast Chill Cycle (Hard or Soft):

During the blast chill hard cycle the air temperature inside the cabinet should go down to

approximately 14°F (-10°C). This is for the timed chilling cycle only. During soft chill cycle the air

temperature stays above 32°F (0°C ).

All blast chillers have 3 basic modes:

1. Normal storage: 34°F (1°C) to 37°F (3°C)

2. Blast Chill Hard: 14°F (-10°C)

3. Blast Chill Soft: 34°F (1°C)

DEFROST

At the end of each cycle, a defrost will automatically clear any ice from the evaporator ready for the

next cycle.

During the operation in storage mode a defrost will be performed automatically at the factory preset

intervals of 6 hours.

Furthermore, if a blast cycle is cancelled and the defrost thermostat is measuring 34°F (+1°C) or less,

the machine will automatically proceed to defrost.

When the machine is in the defrost mode the ‘Cabinet Temp’ window of the control panel will display

‘DEF’. When the defrost cycle is finished the compressor will run for approximately 90 seconds before

the fans cut in.

Following every defrost period there is a 3 minute period during which a blast cycle cannot be selected.

This short interval is to allow defrost water to drip away from the evaporator.

The cabinet is now ready to start another cycle if desired. During the defrost operation it is safe to

leave products inside the machine.

ROLL- IN BLAST CHILLERS WITH STORAGE POD

On roll-in chillers fitted with storage refrigeration pods, the roll-in blast chiller will function as a small

cold storage room when the chiller is in store mode. A defrost will occur every six hours for 20 minutes.

When the blast facility is engaged, the storage pod will be disengaged and the main compressor and

main evaporator fan will take over until the end of the blast cycle. Immediately following the blast

cycle, a main defrost period will occur. When the defrost period is complete the main compressor will

start up again, followed 1-2 minutes later by the main evaporator fan for a period of 10 minutes. After

10 minutes the blast chiller will revert to storage mode until the blast facility is once more engaged.

THE CONTROLS

The control panel enables the display of detailed information about the machine and its performance.

If the machine is also fitted with a printer (standard on roll in machines, optional on reach in cabinets),

detailed historical information can be printed out for immediate use or archived.

1. The ‘Cabinet Temp’ display window can be used:

❖To show the cabinet wall temperature.

❖As a count up timer in probe blast.

2. The ‘Probe’ window can show:

❖Temperature during a blast cycle, (blank during store).

❖During a blast if a food probe fails it will display ‘pf’ in its own window. At the end of a blast

cycle it will indicate alarm code in Probe 1 window.

3. For a timed blast, the green row of LEDs show the progress of the blast. Each LED indicates

another 1/10 of the total blast time has started. When there is only approximately 50 seconds left

to blast, the right hand LED will flash. For a probed blast, the green LEDs again show the blast

progress, but this time each LED indicates 1/10 of the temperature excursion between the products

starting temperature and the target end temperature. Cabinet temperature window also acts as a

count up timer showing in minutes the duration of the probed blast.

PROGRAMMING A BLAST CHILL CYCLE:

1. Switch on the chiller at least half an hour before use.

2. Check that the chiller is operating at storage temperature.

3. Load the products to be chilled (see notes on loading).

4. By pressing button ‘1’ select the ‘Chill’ mode.

5. By pressing button ‘2’ select the desired type of blast, hard or soft.

6. By pressing button ‘3’ select the timer for the desired duration, or probed blast.

7. When you are content with your selected program press the ✓✓to start the blast cycle.

8. If you are not content with your selection press the ✗✗button to cancel your 1/2/3 selection.

As each selection is made, the indicator LED will illuminate to show what is chosen. Press ✓✓to accept, or ✗✗to

cancel.

On completion of a cycle, there will be an audible alarm which will cancel automatically after 15 minutes or may

be cancelled with the ✗✗button. ‘DEF’ will then be displayed in the ‘Cabinet Temp’ window of the control panel

and the chiller will then revert to a store mode appropriate to the blast just completed.

During the defrost operation the temperature in the chiller will not exceed 38°F (+3°C) and it is therefore safe

to leave products in the chiller during the defrost cycle.

To save time for repeated identical blast operations, the blast selections are remembered, so when 1 2 3 are

pressed the selections automatically adopt the previous settings on the first push. So the repeat a blast, just

push 1 2 3 ✓✓.

ALARM AND WARNING LEVELS

For the following alarm and warning conditions, an audible alarm will be activated and a warning ticket

will be printed if the printer is fitted. A faulty sensor alarm will be initiated if a sensor fault condition is

detected. If there is an alarm condition, probe 1 window will display an alarm number a0 to a7 during

store (*see alarm table at the top of the next page), but will show the probe temperature during blast.

7-SEG DISPLAYALARM CONDITION

a0 Air on sensor failure

a1 Wall sensor failure

a2 Fin sensor failure

a3 Food probe 1 failure

a4 Food probe 2 failure

a5 Food probe 3 failure

a6 Spare

a7 Power cut detected

Note: If a wall sensor fails it will also read -50.

For each probe only one audible alarm and alarm printout is allowed to be issued each day. This is

to prevent excessive paper use and noise nuisance in the event of an intermittent probe failure.

However, repeated probe failures are displayed on the probe display window, (top window in the case

of 3 probe panels).

To cancel the audible alarm press the ✗button. If the alarm condition still exists the display will

continue to indicate there is a fault.

THERE IS NO RE-SET FACILITY.

THE PRINTER

If fitted and “ON”, the printer is activated after each blast cycle. The printer provides hard copy

historical data of cabinet performance or warning tickets to archive or act upon.

The formats available are:

Midnight Ticket (if programmed)

At midnight a ticket is automatically printed for archiving in the morning. The midnight ticket provides

the following information:

❖Time and date of printout and cabinet number

❖Cabinet temperature at time of printout

❖A graph of cabinet temperature over the preceding 24 hours

Demand Ticket

A ticket may be requested from the control panel by holding the printer ‘On/Off’ button for 5 seconds.

This ticket provides the same information as the midnight ticket except that up to seven days of

historical data are printed.

Alarm or Warning Ticket

A ticket is automatically printed if any condition is detected by the micro controller which may need

attention.

The print function may be terminated by pressing the printer ‘On/Off’ button.

Mains Power Failure Ticket

If mains power fails for more than 5 seconds a ticket is automatically printed which gives the time of

power failure and the time at which power is restored.

Sensor Failure Ticket

If the controller detects that one of its sensors has failed then a warning ticket will be printed.
