VICTORY VBC-350 (01) PDF Document

All VICTORY VBC-350 units are performance tested and thoroughly inspected prior to shipment. 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.

When unpacking your VICTORY VBC-350, remove all external and interior packing and accessories. Ensure all packaging is disposed of safely.

Proper installation is the first step to operation for your VICTORY VBC-350. We recommend that your unit be installed by an authorized Victory Certified Installer.

Leveling: 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, so a level platform/floor should be provided. On models fitted with adjustable legs, leveling may be achieved by adjusting the bottom section of the legs.

Ventilation: For top-mounted refrigeration systems, ensure there is 20” [500mm] between the top of the cabinet and the ceiling for service technician access and ventilation.

After Tipping: If the cabinet has been laid on its back or tipped, DO NOT switch it on immediately. Leave the cabinet in the upright position for at least 12 hours before switching on.

Wiring for the VICTORY VBC-350 should be done by a qualified electrician in accordance with local electrical codes. The VBC-100 and all Roll-In VBC’s (including the VBC-350) are 3-phase and require connection to a suitable supply. All models must be grounded.

Main Control Breakers: Should the VICTORY VBC-350 fail to run on initial connection, check that all Main Control Breakers (MCBs) are in the “ON” position at the back of the cabinet. 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 will always occur during an initial start-up. Press the “CANCEL” button (red with an ‘x’ symbol) to discontinue the error code and audible alarm.

A “Battery Failure Configuration Suspect” error message ticket will always print during an initial start-up. This is not an alarm; it indicates that the back-up batteries that hold the cabinet’s data during a power failure are not fully charged. A full battery charge should be achieved 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, refer to the printer setup instructions.

Regulations state that product should be placed in the VICTORY VBC-350 within 30 minutes from completion of cooking. The packaging and loading method can significantly affect chilling time.

Containers: When blast chilling, always use metal or foil containers, which are good conductors. Plastic or polyurethane containers insulate the food from the cold air. For unportioned food, use a pan that is at least 2-1/2″ [63.5mm] in depth.

Covers: Placing lids or covers on food will increase chilling time but may be useful for delicate foods to avoid dehydration.

Loading: Always load the machine so that cold air can contact all sides of the containers. Avoid stacking containers directly on top of one another, as this will drastically extend chilling time. Be careful not to block the air ducts. Always load the machine before selecting the blast cycle. Do not open the door while the blast cycle is engaged unless unavoidable.

Roll-in Racks: For roll-in rack models like the VICTORY VBC-350, bumper bars are fitted to the inside walls to assist in the correct positioning of the rack(s) to avoid blocking air flow.

Chilled foods can be stored in the VICTORY VBC-350 for up to 5 days at between 32°F/0°C and 38°F/+3°C.

Normal Storage: This is the storage temperature at which food can be held. The VICTORY VBC-350 automatically switches into this mode at the end of each cycle.

Storage Mode: On some chillers, not all fans may operate during storage mode, resulting in reduced air circulation. The unit cycles on the store thermostat, with the sensor placed in the air.

The VICTORY VBC-350 has the facility 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 uses the food core probe to monitor the core temperature of the food. The cycle will not stop until the default temperature (37°F/3°C) is reached. Ensure the probe(s) are located in the product before starting the cycle.

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 the 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)

At the end of each cycle, a defrost will automatically clear any ice from the evaporator. During operation in storage mode, a defrost will be performed automatically at factory preset intervals of 6 hours.

If a blast cycle is cancelled and the defrost thermostat measures 34°F (+1°C) or less, the machine will automatically proceed to defrost.

When the machine is in defrost mode, the ‘Cabinet Temp’ window will display ‘DEF’. When the cycle is finished, the compressor will run for about 90 seconds before the fans cut in.

Following every defrost, there is a 3-minute period during which a blast cycle cannot be selected, allowing defrost water to drip away from the evaporator. It is safe to leave products inside the machine during the defrost operation.

On roll-in chillers like the VICTORY VBC-350 fitted with storage refrigeration pods, the unit functions as a small cold storage room when 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. Once the defrost is complete, the main compressor will start up, followed 1-2 minutes later by the main evaporator fan for a 10-minute period. After 10 minutes, the blast chiller reverts to storage mode until the blast facility is engaged again.

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 checkmark (✓) button to start the blast cycle.

8. If you are not content with your selection, press the ‘X’ button to cancel your 1/2/3 selection.

As each selection is made, the indicator LED will illuminate to show what is chosen. To save time for repeated identical blast operations, the blast selections are remembered. For a repeat blast, just push 1, 2, 3, and ✓.

On completion of a cycle, an audible alarm will sound, which cancels automatically after 15 minutes or can be cancelled with the ‘X’ button. ‘DEF’ will then be displayed in the ‘Cabinet Temp’ window, and the chiller will revert to store mode.

For alarm and warning conditions, an audible alarm will be activated and a warning ticket will be printed if the printer is fitted. If there is an alarm condition, the probe 1 window will display an alarm number from a0 to a7 during store mode. To cancel the audible alarm, press the ‘X’ button. If the alarm condition still exists, the display will continue to indicate a fault. THERE IS NO RE-SET FACILITY.

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 to prevent excessive paper use.

If fitted and “ON”, the printer on your VICTORY VBC-350 is activated after each blast cycle to provide hard copy historical data. The formats available are:

Midnight Ticket (if programmed): At midnight, a ticket is automatically printed for archiving. It provides the time and date of printout, cabinet number, cabinet temperature at the time of printout, and a graph of cabinet temperature over the preceding 24 hours.

Demand Ticket: A ticket may be requested by holding the printer ‘On/Off’ button for 5 seconds. This ticket provides the same information as the midnight ticket, but for up to seven days of historical data.

Alarm or Warning Ticket: A ticket is automatically printed if any condition is detected by the microcontroller that may need attention.

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, a warning ticket will be printed.

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

CAUTION: DO NOT CHANGE any other parameters when setting the date & time. If additional parameters are changed, there is a great possibility that the VBC Cabinet will not function properly and will void the warranty.

A. Enter the Engineering Switch Mode:

1. Turn the control panel “off” by pressing the “standby” button.

2. Press and hold the “1” button.

3. While continuing to hold the “1” button, press and release the “standby” button.

B. Navigate to Time and Date Settings:

Press the “2” or “3” button to step through the engineering settings. When the display shows “ute”, you have reached the time and date settings. The setting functions (e.g., “ute”, “hr”) are only displayed when the “3” button is depressed. When the button is released, the actual setting value will appear.

C. Set the Time and Date:

• Minute (shown as “ute”): Press “✓” to increase or “X” to decrease the minute.

• Hour (shown as “hr”): Press “✓” to increase or “X” to decrease the hour.

• Day (shown as “day”): Press “✓” to increase or “X” to decrease the day.

• Month (shown as “nth”): Press “✓” to increase or “X” to decrease the month.

• Year (shown as “yr”): Press “✓” to increase or “X” to decrease the year.

Note on Year: When entering the year, only one character may be displayed (e.g., 1 = 2001, 2 = 2002, 3 = 2003, etc.).

D. Exit and Confirm:

When entry is complete, press “standby” once to exit the Engineering Switch Mode. Then press “standby” again to turn on the cabinet. Print a demand ticket by holding the printer “on/off” button for five (5) seconds to confirm the new information.

If there is an error in data entry, wait approximately two (2) minutes before restarting the process.

Logger paper should be installed as shown in the manual. For easy installation, it is best to tear the end of a new roll at a 90-degree angle.

Once the logger paper roll has been inserted into the printer, use the “feed” button on the control panel to automatically bring the paper forward.

1. Remove the printer cover and logger paper.

2. Press the end of the print cartridge that says “PUSH” & “EJECT”.

3. Once the cartridge is pressed at the “PUSH” & “EJECT” end, simply remove the cartridge from the printer.

4. Place the new cartridge by carefully putting it at the designated location.

Note: If the printer does not work, check the print cartridge and logger paper for proper installation. An exposed print cartridge ribbon can dry out; adjust to printable fresh ink by turning the wheel in the direction indicated by the arrow. If adjusting the ribbon does not work, change out the print cartridge with the spare provided. All blast chillers are shipped with a spare print cartridge and logger paper. Print cartridges and logger paper can be purchased from a local office supply store.

A power cut does not cause the loss of any accumulated historical data, and no re-programming is necessary. The controller’s battery in the VICTORY VBC-350 is continually charged and provides emergency backup under normal power failure conditions.

Exterior: The exterior of the cabinet is stainless steel. Normal day-to-day cleaning should be done with a soft cloth and soapy water. Always wipe the cabinet vertically in the same direction as the grain in the stainless steel. Never use abrasive materials or chemical cleaners, as they can damage the surface and cause corrosion. Occasionally, polish the exterior with a good stainless steel polish to protect the surface.

Control Panel: 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 with electrical components.

Interior: The racking can be removed for easy cleaning. This should be done on a regular basis with warm water and a soft cloth, drying thoroughly afterward. To remove the racking and shelf supports:

1. First, remove the shelves.

2. Remove the shelf supports by grasping them firmly in the center and lifting slightly.

3. Turn the shelf support towards the interior of the cabinet, pushing it in the center as you twist the support through 90°. The shelf support will be released. (Note: The supports are anti-tilt and may have some resistance at first).

4. When all shelves have been removed, remove the racking by lifting it up and over the nylon retaining blocks.

Cleaning: Clean the gasket weekly with warm soapy water and a soft cloth, being careful not to damage it. DO NOT use a sharp knife to clean or scrape the gasket. Regularly check the gasket for any damage, which can be caused by striking it with a sharp object like the corner of a tray.

Replacement: 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. Work along the gasket, pushing it into the channel, and continue on the other three sides, pushing the corners in last.

The condenser is part of the refrigeration unit and requires cleaning approximately 4 times per year or when the LED indicates. To clean the condenser on your VICTORY VBC-350:

1. Disconnect the main power supply before starting.

2. Brush the fins vertically with a stiff brush, taking care not to damage the fins or push dirt or dust further in.

3. Vacuum away any dislodged dirt and dust.

4. Remember to reconnect the main power supply once finished.

• Pre-chill the cabinet for thirty (30) minutes before your first load to remove interior residual heat.

• Doubling the food thickness triples the pull-down time.

• Don’t stack food and/or containers on top of or alongside each other.

• Covering the food increases pull-down time by 10% – 30%.

• The pull-down rate is initially about 2°F per minute and approaches a final rate of about 2 minutes per degree Fahrenheit.

1. Entering food temperatures (the hotter the initial temperature, the longer the pull-down time).

2. Final food temperature (the colder the final temperature, the longer the pull-down time).

3. Food “thickness” (the greater the distance from the geometric “core” center of the food to its surface, the longer the pull-down time).

4. Food density (the greater the density, the longer the pull-down time).

5. Food thermal conductivity (the lower the conductivity, the longer the pull-down time).

6. Food specific heats (the higher the specific heat, the longer the pull-down time).

7. Container surface area (the smaller the surface area, the longer the pull-down time).

8. Container material (metals are conductors and result in a shorter pull-down time than plastics, which are insulators).

9. Covering material (metal is preferred over plastic for the reason above).

10. Covering method-cover such as aluminum 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, its elimination shortens pull-down time.

11. “Delta T” is the temperature difference between the food and the blast of air. The greater the “Delta T,” the quicker the pull-down time.

12. Air velocity (the greater the air velocity across the food, the faster the pull-down time).

13. Amount (weight) of food put in compared to the rated capacity of the machine. Exceeding the capacity increases the pull-down time.

14. Mechanical problems (equipment not operating at full efficiency takes longer to pull down).

CAUTION: Disconnect Power Supply Prior to Attempting Any Service!
