VICTORY VBC-480 (01) PDF Document

Upon receiving your VICTORY VBC-480, 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.

For proper installation of your VICTORY VBC-480, please follow these guidelines:

1. The cabinet should stand level to ensure correct operation of self-closing doors and proper drainage of condensate from the evaporator.

2. For models fitted with non-adjustable casters, a level platform or floor must be provided. For models with adjustable legs, leveling can be achieved by adjusting the bottom section of the legs.

3. 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.

4. If the cabinet has been laid on its back or tipped, DO NOT switch it on immediately. You must leave the cabinet in the upright position for at least 12 hours before switching it on.

During the initial start-up, follow these steps:

Main Control Breakers: If the equipment fails to run, check that all Main Control Breakers (MCBs) at the back of the cabinet are in the “ON” position. The “ON” position is confirmed by red indicators on the MCBs.

Initial Start-Up Error Codes & Checks:

1. 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 alarm.

2. A “Battery Failure Configuration Suspect” error message ticket will always print. This indicates that the back-up batteries are not yet fully charged. A full battery charge should be achieved within 24 hours of start-up.

3. Check the time and date on the printed tickets. If the information is incorrect or the paper is not feeding properly, refer to the printer setup instructions.

Follow these guidelines for optimal performance:

• Product should be placed in the Blast Chiller within 30 minutes of cooking completion.

• Always use metal or foil containers, as they are good conductors. Plastic or polyurethane containers insulate food from cold air.

• For unportioned food, use a pan that is at least 2-1/2 inches (63.5mm) deep.

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

• Load the machine so that cold air can contact all sides of the containers. Avoid stacking containers directly on top of one another.

• 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 unavoidable.

• For roll-in rack models like the VICTORY VBC-480, bumper bars are fitted to assist in correct positioning of the rack(s) to avoid blocking air flow.

The VICTORY VBC-480 has been set up at the factory and does not require further adjustments. The control systems are micro-processor based and should only be reset by a qualified service technician.

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

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

Blast Chill Cycle (Hard or Soft):

• During the hard chill cycle, the air temperature inside the cabinet can go down to approximately 14°F (-10°C). This is for timed chilling only.

• During the soft chill cycle, the air temperature stays above 32°F (0°C).

The three basic modes are:

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)

• A defrost cycle will automatically run at the end of each blast chill cycle to clear ice from the evaporator.

• During 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 is measuring 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’.

• Following every defrost, there is a 3-minute period to allow defrost water to drip away, during which a blast cycle cannot be selected.

It is safe to leave products inside the machine during the defrost operation.

To program a blast chill cycle, follow these steps:

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.

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 selection.

To save time, the blast selections are remembered. For a repeat blast, you can just push buttons 1, 2, 3, and then the checkmark (✓).

The 7-segment display will show the following codes for alarm conditions:

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.

If fitted and “ON”, the printer is activated after each blast cycle. The available formats are:

• Midnight Ticket (if programmed): Automatically printed at midnight for archiving. It provides the time and date, cabinet temperature, and a graph of cabinet temperature over the preceding 24 hours.

• Demand Ticket: Requested by holding the printer ‘On/Off’ button for 5 seconds. It provides the same information as the midnight ticket but can cover up to seven days of historical data.

• Alarm or Warning Ticket: Automatically printed if the micro controller detects a condition that may need attention.

• Mains Power Failure Ticket: Automatically printed if mains power fails for more than 5 seconds, showing the time of failure and restoration.

• Sensor Failure Ticket: A warning ticket will be printed if the controller detects a failed sensor.

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 warranty.

Logger Paper Installation:

1. Tear the end of a new paper roll at a 90-degree angle for easy installation.

2. Insert the logger paper roll into the printer as shown in the manual’s diagram.

3. Use the “feed” button on the control panel to automatically advance the paper.

Print Cartridge Removal & Installation:

1. Remove the printer cover and logger paper.

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

3. Once pressed, simply remove the old cartridge from the printer.

4. Place the new cartridge in the designated location. Turn the wheel on the cartridge in the direction of the arrow to adjust to fresh ink if needed.

Cleaning Exterior: The stainless steel exterior should be cleaned with a soft cloth and soapy water. Always wipe vertically in the same direction as the grain. Never use abrasive materials or chemical cleaners. Occasionally polish with a good stainless steel polish.

Cleaning Interior: The interior 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 afterwards. To remove racking, first remove the shelves, then the shelf supports by grasping them in the center, lifting slightly, and twisting them 90 degrees toward the interior of the cabinet. Once all shelves and supports are removed, lift the racking up and over the nylon retaining blocks.

Door Gasket: Clean the gasket weekly with warm soapy water and a soft cloth. Do not use sharp objects. Damaged gaskets do not seal correctly and should be replaced. To replace, pull out the old gasket and push the new one into the channel, working along all sides and pushing the corners in last.

Condenser Cleaning: The condenser requires cleaning approximately 4 times per year. Disconnect the main power supply before starting. Brush the fins vertically with a stiff brush, being careful not to damage them. Vacuum away any dirt or dust. Reconnect the main power supply once finished.

• Pre-chill the cabinet for thirty (30) minutes before the 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 about 2 minutes per degree Fahrenheit when approaching the final temperature.

Several factors can affect the pull-down time:

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 core to the 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 (conductors) result in a shorter pull-down time than plastics (insulators).

9. Covering material: Metal is preferred over plastic.

10. Covering method: A cover like aluminum foil in direct contact with food eliminates “dead air space,” which is an insulator, shortening pull-down time.

11. “Delta T”: 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 increases the pull-down time.

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

If your VICTORY VBC-480 is not running, check the following possible causes and remedies. CAUTION: Disconnect Power Supply Prior to Attempting Any Service.

• Circuit Breaker tripped: Reset the circuit breaker. Ensure breakers show red indicators for the “ON” position.

• Power Cord unplugged: Plug in the power cord.

• Main power supply turned “OFF”: Turn the main power supply “ON”.

• Improper voltage supplied to cabinet: Supply the correct voltage. Do not use extension cords or put other equipment on the circuit.

• Cabinet in defrost cycle: Allow the defrost cycle to finish.

If the condensing unit runs excessively, consider these potential issues. CAUTION: Disconnect Power Supply Prior to Attempting Any Service.

• Cabinet not pre-chilled: Remove the product load and pre-chill the cabinet for approximately 30 minutes.

• Excessive amount of warm product: Allow adequate time for the product to cool down.

• Whole product loads placed in cabinet: Portion the product loads.

• Improper use of “Soft Chill” mode: Use “Soft Chill” for delicate and less dense product loads only.

• Prolonged door opening or door ajar: Ensure the door is closed when not in use and avoid prolonged openings.

• Door gasket not seating properly: Check the gasket condition. Adjust the door or replace the gasket.

• Dirty Condenser coil: Clean the condenser coil.

• Improper air flow around Condensing Unit: Ensure adequate air space and relocate away from heat sources or direct sunlight.

• Evaporator coil blocked with ice: Turn the unit off to defrost, or manually force a defrost by holding the “cancel” button (red ‘X’) for 5 seconds while the cabinet is “ON”.

If the cabinet temperature is too high, check these points. CAUTION: Disconnect Power Supply Prior to Attempting Any Service.

• Poor air circulation in cabinet: Move the product load away from the fan(s).

• Excessive amount of warm product: Allow adequate time for the product to cool down.

• Door(s) ajar: Make sure doors are closed when not in use.

• Dirty condenser coil: Clean the condenser coil.

• Insufficient clearance or high ambient temperature: Ensure adequate air space and relocate away from heat-generating equipment.

• Evaporator coil blocked with ice: Turn the unit off to defrost or manually force a defrost by holding the red button with “X” for 5 seconds.

Here are solutions for other common issues. CAUTION: Disconnect Power Supply Prior to Attempting Any Service.

• Cabinet is noisy: Locate and tighten loose part(s).

• Product taking too long to pull-down: Uncover the product or use metal pans. For dense products, use “Hard Chill” mode.

• Compressor will not start, hums, and trips breaker: This could be due to a dirty condenser coil, excessive heat from nearby equipment, or incorrect voltage. Clean the condenser coil, relocate the cabinet, or check and correct the supply voltage.

• Door won’t close tight: The cabinet may not be level. Level the cabinet by adjusting or shimming casters or legs.

• Water or ice at bottom of cabinet: The product load may be too hot. Cool down the product load before placing it into the cabinet.

• Error Code displayed: This could be a loose/defective food probe or a main power failure. Press the “X” (cancel) button to stop the alarm sound.

• Printer paper not feeding or printing tickets: The printer paper may be jamming or finished. Reload the paper.

• No printout on printer paper: The cartridge may be dry or need replacement. Change the print cartridge.
