OPERATION AND CARE OF

MODEL OV520 RACK OVEN

RETAIN THIS MANUAL FOR FUTURE REFERENCE

GENERAL

The Baxter OV520 Rack Oven accommodates a roll-in rack. It is equipped with the Smart Touch™ control for baking, roasting, and/or steaming applications. A mechanism in the oven ceiling picks up and rotates the rack during the baking/cooking cycle.

• Model OV520G1 is rated at 180,000 Btu/hr, natural or propane gas.

• Model OV520G2 is rated at 275,000 Btu/hr, natural or propane gas.

• Model OV520E1 is rated at 25.7 - 34.2kW.

• Model OV520E2 is rated at 38.5 - 51.3kW.

All instructions herein related to shutdown and restart procedures, cleaning, maintenance and any other service work are prepared to be used by trained personnel and should not be used by anyone who is not

properly qualied.

INSTALLATION

See appropriate OV520E/OV52G Installation Manual.

WARRANTY

To activate warranty, the Baxter OV520-series Rack Oven must have a startup performed by an authorized Baxter servicer.

Failure to follow use, care, cleaning, and/or maintenance instructions in this Operator Manual may void any product warranty provided by Baxter.

OPERATION

BASIC OPERATION

For best results, the oven must be preheated to bake temperature before baking begins.

1. The door must be closed for oven to heat. The rack carrier will lift and rotate only during timed bake.

NOTE: The rack carrier will be in the unload position from the last bake. If the rack carrier was moved out of the home position, the rack carrier will lift and turn to the unload position when the door is opened.

2. Press the POWER button below the user display screen to turn the oven on.

– 5 –

Page 6

3. The oven will preheat to the default preheat temperature. See Client Parameters for information about setting the default preheat temperature. See Auto Mode or Manual Mode for instructions on how to adjust the temperature.

4. For optimum steaming capability, allow 30 minutes after the oven has reached the set temperature for the steam system to charge.

5. The oven is now ready for baking operations.

The oven and its parts are hot. To prevent burns, use hot pads or protective mitts

when loading or unloading the oven.

Hot air and steam are released from the oven interior when the loading door is

opened. To avoid burns, open the door slowly and keep clear of the opening.

6. To adjust bake settings, see the Auto Mode or Manual Mode sections.

7. After the oven is preheated and the product is ready to bake, slowly open the door and load the rack onto the oven carrier.

8. Close the door and touch the Start button. The rack will lift and rotate.

9. The oven will beep after the set time ends. Touch Stop or open the door to silence the beeper.

10. Open door. Allow the rack carrier to stop and lower. The rack can now be removed.

RACK LOADING

1. Type B and C rack carriers are equipped with stops on both ends. For B lifts, ensure stop ap is in

the up position to load the rack on the rack carrier. For C lifts, push rack stop to the left after rack is loaded. Note: C carriers for single rack ovens only have one stop. Push rack in until rack hits rear stop.

2. Roll the rack into the oven so the end brackets channel onto the rack carrier. When using racks equipped with pan stops, load racks so stops will prevent movement of trays toward user when racks are unloaded. Position pans so they do not extend beyond the rack. If the pans extend beyond the rack, it may cause the rack to get jammed when rotating.

3. Close the loading door. The rack carrier will lift and rotate only during timed bake.

The oven and its parts are hot. To prevent burns, use hot pads or protective mitts

when loading or unloading the oven.

Hot air and steam are released from the oven interior when the loading door is

opened. To avoid burns, open the door slowly and keep clear of the opening.

RACK UNLOADING

1. Touch Stop and/or open the loading door to silence the beeper.

2. Wait for the rack carrier to stop and lower.

3. For B lifts, push the rack stop down to unload the rack from the rack carrier. For C lifts, push rack stop to the right to open.

4. Roll the rack from the rack carrier.

5. Close the loading door.

PREVENTIVE MAINTENANCE

The OV520 Rack Oven must be kept on a regular preventive maintenance schedule. Ovens require

specic preventive maintenance based on usage and environmental factors. The failure to have the oven

properly maintained by following recommended preventive maintenance procedures may result in higher repair costs, shortened equipment life, or unsafe operating conditions.

It is the owner’s responsibility to make sure preventive maintenance is performed on the rack oven. This

will ensure continued safe and reliable operation. Contact an authorized Baxter service o󰀩ce to provide

this skilled service for you.

OWNER PREVENTIVE MAINTENANCE PROCEDURE

INTRODUCTION

This customer PM section includes procedures to inspect for proper operation and cleaning of components. Owner Preventive Maintenance Procedures are written for gas ovens. They can also be used for electric ovens by omitting the steps that refer to components found only on gas ovens. To maintain the safety and performance of bakery ovens, a program of scheduled periodic maintenance must be implemented. It is the sole responsibility of the user to establish, schedule, and enforce such a program. Although the service interval will vary depending on the environment in which the equipment is operating, it is recommended that PM be performed and all safety devices are checked at a minimum of 12-month intervals. Check with

the authority having local jurisdiction if there are specic maintenance requirements specied by local,

state, or national codes. A convenient PM Checklist is provided at the end of this section.

NOTE: This PM procedure does not discuss repair or replacement of components. Upon completion of

the PM procedure, you will need to contact a qualied servicer for any needed repairs.

Tools Used for Inspection Procedure

• Standard set of hand tools

• Vacuum cleaner - shop vac

PREVENTIVE MAINTENANCE PROCEDURE

Disconnect the electrical power from the machine and follow lockout / tagout

procedures. There may be multiple circuits. Be sure all circuits are disconnected.

Shut o󰀨 the gas before servicing the unit.

Certain procedures in this section may require electrical test or measurements while power is applied to the machine. Exercise extreme caution at all times. If test points are not easily accessible, disconnect power and follow lockout/tagout procedures, attach test equipment, and reapply power to test.
