Rotisserie/Convection Oven Introduction
Specific Precautions
Equipotential Ground Plane
When a high current flows through a conductor, differences in potent ial appear between the conductor and nearby metallic surfaces near the appliance. As a result, sparks may be produced between the appliance and surrounding metal surfac es. These sparks could cause serious injury, damage, or fire.
BKI provides an Equipotential ground terminal for the connection of a bonding conductor after the installation of the appliance per lEC60417-1. This terminal is located on the drive side of the oven base and is marked with this symbol.
Full Disconnection for IEC / CE Regulations
In accordance with Local and/or National wiring codes, the installer must provide a means of full disconnection for overvoltage Category III conditions. An IEC approved cord and plug combination will meet this requirement.
Units not provided with a cord and plug do not meet this requirement. In accordance with Local and/or National wiring codes, the installer must provide the means of full disconnection.
Safe Work Practices
Wear Safe Clothing Appropriate To Your Job
Always wear your insulated mitts when handling hot oven parts or touch any hot metal surface. If you lose or damage your mitts, you can buy new ones at your local restaurant equipment supply store or from your local BKI Distributor.

Health And Sanitation Practices
BKI Rotisserie Ovens are manufactured to comply with health regulations and are tested and certified to NSF and
FSA standards. You must operate the equipment properly, using only quality products and use meat thermometers to insure meats are thoroughly cooked.
Food Handling
Wash hands thoroughly in warm, soapy water after handling raw poultry or meats.  Clean and sanitize all utensils and surfaces that have been in contact with raw products. Clean and
sanitize the meat forks or baskets between cooking.
Never place cooked meats on the same surfaces used to prepare raw me ats, unless the area has been
thoroughly cleaned and sanitized.
Storage Of Raw Meats
Designate an area or shelf strictly for the storage of all raw meats to be used in the rotisserie.  Raw product must always be stored at temperatures below 38° F. (3° C.).  Never store or mix raw foods above cooked foods, as this is a health hazard.
foods contaminate cooked or processed foods.
All chicken and chicken parts to be stored overnight must be thoroughly iced down and refrigerated.
The drippings from raw
Coding Cooked Foods
All products cooked during the day should be sold the same day. NOTE: It is not the intent of the rotisserie program to have unsold merchandise at the end of the cooking day.
Follow your company’s procedures for the handling of any leftover product.
Storage Of Prepared Foods
Cold foods should be kept at or below 38° F. (3° C.).  Hot foods must be maintained to meet local health codes, usually a minimum 145° F. (63° C.).

Accessory Use
Standard Meat forks
The standard meat forks are ideal for chicken and poultry. Use the following procedure to prepare the bird for loading in the oven.
1. Fold wings to back, place on back with cavity away from you.
2. Run pointed ends of meat fork through sides of chicken under wings and through thighs (breast up and legs down). Ensure that legs of adjacent birds DO NOT PRESS TIGHTLY TOGETHER, this will cause the area of contact to be under-cooked!
3. Load the meat-forks by holding the meat-fork with the handle to the right–hand side, facing up.
4. Open the oven door.
5. Press Rotor Switch to rotate rotor to open position if required.
6. Place the pointed ends of the meat-fork into the left-hand disc holes.
7. From the control side, push the meat-fork into the disc to allow the right-hand (handle end) pins locate into the right-hand disc.
8. Be sure to adjust the meat-fork position so that the handle end locates firmly in the spit groove.
Baskets
Baskets can be used for large chickens or other meats. After loading with product, simply locate pins in the holes on the discs.

Rotisserie/Convection Oven Operation
Item # Description Function
1 Digital Timer The digital timer consists of an LED, display, beeper and 8 buttons described below:
LED indicator – Prior to the start of a timing cycle the LED will be OFF. When running a timing cycle the LED will flash. At the end of a timing cycle the LED will turn ON steady. When idle the LED is off.
TIME SELECT (2 arrow buttons) – Two arrow buttons on the front panel are used to set the time. Hold the UP ARROW button down to increase the time. The longer the button is held down, the faster the rate at which the time will increase. The DOWN ARROW button is used in the same manner as the UP ARROW button except it will cause the time to decrease. The time is increased or decreased in 30-second increments.
START/STOP button
Starting the Timer - Pressing this button while the timer is not active will cause the timer to begin counting down the time on the display. Stopping the Timer - Pressing this button while the timer is active will stop the timer from counting down and display the remaining time. Time cannot be changed with the TIME SELECT buttons at this point. If this button is pressed again the timer will continue counting down from the point it was stopped. Resetting the Timer - Pressing and holding this button for longer than two (2) seconds will reset the timer and the display will return to the original starting time. At this point, time can be changed using the TIME SELECT buttons or the preset buttons.
ALARM button - This button allows the user to set an elapsed time at which the internal alarm will sound during a cycle. The time is set by pressing and holding the ALARM button while using the UP and DOWN arrows to change the time. The controller will limit the alarm time to be less than the currently programmed interval cycle time. The default alarm time is 0:00 which disables it. The ALARM time is saved on power down in the same manner as the last interval time. When a time cycle is running and the alarm time has elapsed the internal alarm will so und for 10 seconds. For example, a cycle time 10:00 and alarm time of 2:00 would cause the alarm to sound for 10 seconds once the controller has counted down from 10:00 to 8:00.
A, B, C, D preset buttons - These buttons are used to save and recall preset cycle and alarm times, saving operator time and minimizing error when changing interval cycle times and alarm times. To save the current interval and alarm times into one of the preset locations, press and hold the A, B, C, or D preset button for 2 seconds and the controller will double chirp to indicate the times have been saved. To recall any preset time, press and quickly release the appropriate button and the time values are loaded and displayed.
Beeper – A beeper sounds when the timer counts down to 0. Pressing the START/STOP button stops the beeper and resets the timer causing the display to return to the original starting time. At this point, time can be changed using the TIME SELECT buttons or the preset buttons. The beeper will also sound for 10 seconds if the alarm time has elapsed during a timing cycle.
Display – Used to display the time.
2 Thermostat Used to set the cook temperature. Turn the thermostat knob clockwise to the desired
cook temperature. A light will turn on when the thermostat calls for heat. The light will turn off when the temperature is reached.
