VICTORY VBC-175 (01) PDF Document

Upon receipt of your VICTORY VBC-175, 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 damage incurred.

Proper installation is the first step to operation. We recommend that your VICTORY VBC-175 be installed by an authorized Victory Certified Installer.

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

2. 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.

3. 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.

4. 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-175 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 Roll-In VBC’s (VBC-175, VBC-220, VBC-350, VBC-480 & VBC-660) are 3-phase and require connection to a suitable supply.

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 the 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 will always occur during an initial start-up. Press the “CANCEL” button (red with x 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. This 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 Blast Chiller within 30 minutes from completion of cooking. The packaging and loading method can have a significant effect on 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. When chilling unportioned food, we recommend the use of an appropriate pan that is at least 2-1/2″ [63.5mm] in depth. Placing lids or covers on food will also increase the chilling time but may be useful for some delicate foods to avoid dehydration.

Loading: Always load your VICTORY VBC-175 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. Take special care not to block the air ducts.

Operation: 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.

Roll-In Models: For roll-in rack models like the VICTORY VBC-175, 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.

Chilled foods can be stored for up to 5 days at between 32°F/0°C and 38°F/+3°C.

All VICTORY VBC-175 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 adopts the previous settings on the first push. So repeating a 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 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, ready for the next cycle.

During 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.

On roll-in chillers like the VICTORY VBC-175 that are 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.

1. The ‘Cabinet Temp’ display window can be used to show the cabinet wall temperature. It also serves as a count-up timer in a probe blast.

2. The ‘Probe’ window can show the temperature during a blast cycle (it is blank during store mode). 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 the alarm code in the Probe 1 window.

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 X 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 X to cancel.

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 to repeat a blast, just push 1 2 3 ✓.

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

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, but will show the probe temperature during a blast. The alarm codes are as follows:

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

To cancel the audible alarm, press the X button. If the alarm condition still exists, the display will continue to indicate there is a fault. THERE IS NO RE-SET FACILITY.

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

Midnight Ticket (if programmed): At midnight, a ticket is automatically printed for archiving in the morning. 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 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.

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.

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 warranty!

A. Enter the Engineering Switch Mode by doing the following:

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 “standby” button.

B. 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. When entry is complete, press “standby” once to exit the Engineering Switch Mode. Then press “standby” again to turn on the cabinet.

D. Print a demand ticket by holding the printer “on/off” button for five (5) seconds. A printout will be produced to confirm new information has been entered.

*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. 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.

• Remove the printer cover and logger paper.

• Press the end of the print cartridge that calls out “PUSH” & “EJECT”.

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

• 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. Change out the print cartridge with the spare provided if adjusting the ribbon does not work.

A power cut does not cause the loss of any accumulated historical data, and no re-programming is necessary. The controller’s battery 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 cleaners, or chemical cleaners, as they can damage the surface and cause corrosion. Occasionally, the exterior should be polished with a good stainless steel polish to protect the surface. Do not use abrasive cleaners, chemicals, or scouring pads on the control panel. Clean the control panel only with a soft damp cloth.

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 afterwards. To remove the racking and shelf supports, first remove the shelves. Then, remove the shelf supports by grasping firmly in the center and lifting slightly. Turn the shelf support towards the interior of the cabinet by pushing it in the center as you twist the support through 90°. The shelf support will be released. (Note: the supports are designed to be anti-tilt and you may experience some resistance at first which will be overcome with practice). When all shelves have been removed, remove the racking by lifting up and over the nylon retaining blocks.

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 the gasket for any damage. Damaged gaskets do not seal correctly and can increase electricity consumption.

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, continue in the same way on the other three sides, pushing the corners in last.

The condenser, which is part of the refrigeration unit, is located in the unit compartment and requires cleaning approximately 4 times per year or when the LED indicates. To clean the condenser, disconnect the main power supply before starting. Then, brush the fins vertically with a stiff brush, taking care not to damage the fins or push dirt or dust further in, and vacuum away. Remember to reconnect the main power supply once finished.

☐ Pre-chill the cabinet for thirty (30) minutes before you do 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 or alongside of each other.

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

☐ Pull-down rate initially is about 2°F per minute and approaching final temperature is 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 reasons above.

10. Covering method: A 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”: 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 takes longer to pull down.

If your VICTORY VBC-175 is not running, check the following possible causes and remedies:

• Circuit Breaker tripped: Reset the Circuit Breaker. Make sure circuit 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 for a prolonged period, consider these potential causes and solutions:

• Cabinet not pre-chilled prior to placing hot product load: Remove the product load and pre-chill the cabinet for approximately 30 minutes (this only applies to cabinets that do not stay on all the time).

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

• Whole product loads placed in cabinet: Portion the product load(s).

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

• Prolonged door opening or door ajar: Make sure the door is closed when not in use. Avoid prolonged door 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, relocate away from heat-generating equipment, direct sunlight, or the direct path of air conditioning or heating ducts.

• Evaporator coil blocked with ice: Turn the unit off and allow the coil to defrost or manually force a defrost. While the cabinet is “ON”, hold the “cancel” button for 5 seconds for a manual defrost.

If the cabinet temperature is too high, please check the following:

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

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

• Prolonged door openings or door(s) ajar: Make sure the door(s) are closed when not in use. Avoid prolonged door openings.

• Dirty condenser coil: Clean the condenser coil.

• Insufficient clearance around cabinet or excessively high ambient temperature: Ensure adequate air space, relocate away from heat-generating equipment (ovens, fryers, etc.), and out of direct sunlight.

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

If your food is taking too long to cool down, check these possibilities:

• Product load covered: Uncover the product or try to use metal pans.

• Improper use of “Soft Chill” mode: Use “Hard Chill” for product loads that are of great density.

If the compressor is not starting, please check the following:

• Dirty Condenser coil: Clean the condenser coil.

• Excessive heat generated from equipment nearby: Relocate the cabinet or adjacent heat-generating equipment.

• Voltage to cabinet too high or too low: Check and correct the supply voltage.

If the cabinet door is not closing properly because the cabinet is not level, you should level the cabinet by adjusting the casters or legs. Shim casters or legs if necessary.

If you find water or ice at the bottom of the cabinet, it may be because the product load was too hot. Cool down the product load before placing it into the cabinet.

An error code indicates 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 due to the printer paper jamming, not being straight or properly seated on the spool, or the printer paper spool being finished. Reload the paper according to the instructions.

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