VICTORY VBC-75 (01) PDF Document

Upon receipt of your VICTORY VBC-75, 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.

For proper installation of your VICTORY VBC-75, follow these guidelines:

• 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.

• 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.

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.

If the equipment fails to run on initial connection, please 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.

An “a7” error code, indicating a loss of power, with an audible alarm will always occur during an initial start-up. This is normal. Press the “CANCEL” button (red with an ‘x’ symbol) to discontinue the error code and audible alarm.

This error message ticket will always print during an initial start-up and is not a cause for alarm. It is only indicating 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.

For optimal performance, follow these loading and packing guidelines:

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

• 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, use a 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 delicate foods to avoid dehydration.

• 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 the chilling time.

• Take special care not to block the air ducts.

• Always load the machine before selecting the blast cycle.

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

The VICTORY VBC-75 blast chiller has 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)

The defrost cycle operates as follows:

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

• During operation in storage mode, a defrost will be performed automatically at the 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.

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

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

Follow these steps to program 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.

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.

To save time for repeated identical blast operations, the blast selections are remembered. To repeat a blast, just push 1, 2, 3, and then the checkmark (✓).

If there is an alarm condition, the probe 1 window will display an alarm number from a0 to a7 during store mode. The meanings 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.

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.

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

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

Logger paper should be installed as shown. 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. If the exposed print cartridge ribbon is dry, you can adjust to printable fresh ink by turning the wheel in the direction indicated by the arrow.

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 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. Occasionally, the exterior should be polished with a good stainless steel polish to protect the surface.

Interior: The racking can be removed for easy cleaning. First, remove the shelves. Then, remove the shelf supports by grasping them firmly in the center, lifting slightly, and turning the support towards the interior of the cabinet by pushing it in the center as you twist the support through 90°. When all shelves and supports have been removed, remove the racking by lifting up and over the nylon retaining blocks. Clean on a regular basis with warm water and a soft cloth, and dry thoroughly afterward.

Control Panel: Clean the control panel only with a soft damp cloth. Avoid excess water on the control panel and other areas where electrical components are fitted. Do not use abrasive cleaners, chemicals, or scouring pads.

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.

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 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:

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 the loosened debris.

4. 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 each other.

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

• The pull-down rate is initially about 2°F per minute and slows as it approaches 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 than plastics which are insulators).

9. Covering material (metal is preferred instead of plastic).

10. Covering method (a cover like aluminum foil in direct contact with food eliminates the “dead air space” and shortens pull-down time).

11. “Delta T” (the greater the temperature difference between the food and the blast of air, 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 takes longer to pull down).

If your VICTORY VBC-75 is not running, check the following:

• **Circuit Breaker tripped:** Reset the Circuit Breaker (make sure it shows red indicators for “ON” position).

• **Power Cord unplugged:** Plug in the power cord.

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

• **Improper voltage supplied:** Ensure the correct voltage is supplied. Do not use extension cords.

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

If the condensing unit runs for a prolonged period, consider these causes:

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

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

• **Improper use of “Soft Chill” mode:** Use “Soft Chill” for delicate items only. Use “Hard Chill” for dense products.

• **Prolonged door opening or door ajar:** Make sure the door is closed when not in use.

• **Door gasket not sealing properly:** Check the gasket’s condition. Adjust the door or replace the gasket.

• **Dirty Condenser coil:** Clean the condenser coil.

• **Improper air flow:** Ensure adequate air space and relocate the unit away from heat sources.

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

A high cabinet temperature could be caused by:

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

• **Door(s) left ajar:** Make sure the door(s) 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.

If the door won’t close tight, the cabinet may not be level. Level the cabinet by adjusting the casters or legs. Shim them if necessary.

This may be caused by placing a product load that is too hot into the cabinet. Cool down the product load before placing it into the cabinet.

• **Printer paper not feeding or printing tickets:** The paper may be jamming, not straight, or not properly seated on the spool. The paper roll may be finished. Reload the paper as per instructions.

• **No printout on printer paper:** The cartridge may be dry or needs to be replaced. Change the print cartridge.
