VICTORY VBC-35 (01) PDF Document

Upon receipt of your VICTORY VBC-35, you should 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 the damage incurred.

Proper installation is the first step to operation. It is recommended 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 must be provided. On models with adjustable legs, leveling can be achieved by adjusting the bottom section of the legs.

Ventilation: For top-mounted refrigeration systems, ensure there is 20 inches (500mm) of space 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 it on.

Wiring for the VICTORY VBC-35 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. It is recommended that if the plug or cable fails, you contact Victory’s parts department for a replacement part.

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

Main Control Breakers: If the equipment fails 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 Error Codes: 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.

Battery Message: A “Battery Failure Configuration Suspect” error message ticket will always print during an initial start-up. This is not a cause for 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.

Time and Date Check: 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 instructions for printer set up.

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

• 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, it is recommended to use an appropriate pan that is at least 2-1/2″ (63.5mm) in depth.

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

• Always load the machine in a way that allows 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.

• Take special care 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 it is unavoidable.

Chilled foods can be stored in the VICTORY VBC-35 for up to 5 days at a temperature between 32°F/0°C and 38°F/+3°C.

The VICTORY VBC-35 has three basic operating modes:

1. Normal storage: 34°F (1°C) to 37°F (3°C). This is the storage temperature at which food can be held, and the Blast Chiller automatically switches to this mode at the end of each cycle.

2. Blast Chill Hard: 14°F (-10°C). During this timed cycle, the air temperature inside the cabinet drops to approximately 14°F (-10°C).

3. Blast Chill Soft: 34°F (1°C). During this cycle, the air temperature stays above 32°F (0°C).

At the end of each blast chill cycle, a defrost will automatically clear any ice from the evaporator.

When operating in storage mode, a defrost will be performed automatically at the factory preset interval 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.

During the defrost mode, the ‘Cabinet Temp’ window on the control panel will display ‘DEF’. When the cycle is finished, the compressor runs for about 90 seconds before the fans start. Following every defrost, there is a 3-minute period during which a blast cycle cannot be selected to allow defrost water to drip away. It is safe to leave products inside the machine during the defrost operation.

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 ✓ 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. When 1, 2, and 3 are pressed, the selections automatically adopt the previous settings. So, to repeat a blast, just push 1, 2, 3, ✓.

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, and the chiller will revert to store mode.

If there is an alarm condition on your VICTORY VBC-35, the probe 1 window will display an alarm number from a0 to a7. To cancel the audible alarm, press the X button. The following table explains the alarm codes:

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

If your VICTORY VBC-35 is fitted with a printer and it is “ON”, it is activated after each blast cycle to provide hard copy historical data. The available formats 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: This can be requested by holding the printer ‘On/Off’ button for 5 seconds. It 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 micro controller 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.

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 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.

C. Set the Time and Date:

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 and can then be set.

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

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

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

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

• Year (shown as “yr”) -> Press “✓” to increase or “X” to decrease year. (Note: For 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.

Special Note: If there is information entered by error, wait approximately two (2) minutes before starting the process over.

Logger paper should be installed as shown in the manual’s diagram. It is best to tear the end of a new roll at a 90-degree angle for easy installation.

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 in the designated location.

Note: If the printer does not work, check the print cartridge and logger paper for proper installation. If the exposed print cartridge ribbon has dried out, adjust to fresh ink by turning the wheel in the direction indicated by the arrow. Change out the print cartridge with the spare provided if adjusting the ribbon does not work. 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-35 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 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. Never use abrasive materials or chemical cleaners, as they can damage the surface. 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 it only with a soft damp cloth and avoid excess water.

Interior: The racking can be removed for easy cleaning. This should be done on a regular basis with warm water and a soft cloth, and dried thoroughly afterward. To remove the racking and shelf supports, first remove the shelves. Then, remove the shelf supports by grasping them firmly in the center, lifting slightly, and twisting them 90° towards the interior of the cabinet to release them. Once all shelves are removed, lift the racking up and over the nylon retaining blocks to remove it.

Cleaning: 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 for damage.

Replacement: Damaged gaskets are easily replaced. To fit a new gasket, simply pull out the old gasket. 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.

The condenser requires cleaning approximately 4 times per year or when the LED indicates. To clean it, follow these steps:

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 further in.

3. Vacuum away the 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 is about 2 minutes per degree Fahrenheit when approaching the final temperature.

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 reasons mentioned above.

10. Covering method: A cover like aluminum foil or “stretch wrap film” placed in direct contact with food eliminates the “dead air space” insulator between the cover and the food, which shortens pull-down time.

11. “Delta T”: This 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: Exceeding the rated capacity of the machine increases the pull-down time.

14. Mechanical problems: Equipment not operating at full efficiency will take longer to pull down.

If there is water or ice at the bottom of the cabinet, the product load may be too hot. Cool down the product load before placing it into the cabinet.

If an error code is displayed, it may be due to a loose or defective food probe/thermocouple or a main power failure. Press the “X” (cancel) button to stop the alarm sound.

This could be caused by the printer paper jamming, not being straight, or not being properly seated on the spool. It could also mean the printer paper spool is finished. Reload the paper according to the instructions in the manual.

If there is no printout, the cartridge may be dry or needs to be replaced. Change the print cartridge following the instructions in the manual.
