PREPARING, TYING & SPITTING — CHICKENS ON V-SPITS The rotary oven is not designed to roast frozen foods. Use only fresh or previously thawed product. Bring chickens from cooler. Check temperature — range should be from 37°F to 42°F. Insert approved popper, if available; it will pop out when chicken is done. Using an approved tie, wrap around legs, pulling tie along the back, criss-cross over back. Tie comes over front holding wings to side of chicken. Insert V-Spit through neck first.
INCORRECT SPITTING — CHICKENS ON V-SPITS ➤ WRONG — Angle of spit is in line with breast. This will split the backbone and could possibly result in falling off the spit during cooking. ➤ WRONG — Legs and thighs are not on same side as breast. This could cause legs to fall off during cooking. ➤ WRONG — Legs are being inserted first. This could result in birds moving along spits during cooking.
WARNING: SPITS ARE SHARP. USE CARE WHEN LOADING PRODUCT. SPITTING — CHICKENS ON FORK SPITS Press pointed ends of spits into whole poultry so points go through the chest-wing and leg-thigh regions (Fig. 8). Load four or five chickens on each fork spit. Fig. 8 SPITTING — CHICKENS ON THERMO-WAVE SPITS After tying chickens, insert thermo-wave spit through neck first. Load three or four chickens on each thermo-wave spit.
Loading V-Spits or Thermo-Wave Spits on the Rotor 1. Place pointed end of V-spit into small outside hole on non-drive side of rotor (Fig. 12). 2. Fit notched end of V-spit into appropriate holes on drive side of rotor (Fig. 13). 3. Make sure the spit is level. If the spit is not level, you might be using the wrong holes. NON-DRIVE SIDE DRIVE SIDE Fig. 12 Fig. 13 Loading Fork Spits on the Rotor 1. Place pointed ends of fork spit into appropriate holes on the non-drive side of the rotor (Fig. 14).
PERSONAL PROTECTIVE EQUIPMENT Chickens and accessories are hot. Use care during unloading by using appropriate personal protective equipment such as 18" insulated gloves, an apron, long sleeved clothing and closed toed shoes. UNLOADING ACCESSORIES FROM OVEN Opening the door does not stop the rotor, heaters or fan. 1. Press Press STOP to stop rotation and cooking. Press to allow rotor to advance to unloading position. again to stop rotation. 2. Use insulated gloves.
CLEANING WARNING: DISCONNECT ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES BEFORE CLEANING OR SERVICING. Proper cleaning prolongs the life and productivity of the oven. The oven should be routinely cleaned throughout the day and thoroughly cleaned at the end of the day. Allow oven to cool before cleaning. CAUTION: Do not use oven cleaners. Do not clean with a high pressure hose. 1. Wash door(s) and inside glass with warm soapy water, rinse and dry or use a commercial glass cleaner.
CLEANING GUIDELINES FOR NONSTICK COATED SURFACES Abrasion and aggressive chemicals reduce the life of the nonstick coating. With proper care, the nonstick coated surface should provide a long life of easy-to-clean service. DO NOT do the following: • DO NOT use abrasive cleaning aids such as steel wool. NOTE: Abrasive pads remove the coating over time, significantly reducing the life of the coating. • DO NOT use sharp instruments such as knives, forks, scrapers or metal objects of any kind.
MONTHLY CLEANING Clean ventilation grate and fan blades located in the top of the oven. 1. Remove ventilation grate by unscrewing nuts on both sides of vents. 2. Unscrew nut (clockwise) in center of fan blade. 3. Wash in a sink with warm soapy water. 4. Rinse thoroughly and dry with a soft dry cloth. 5. Wipe fan blades with a clean damp cloth. 6. Dry with a soft dry cloth. 7. After cleaning, reinstall in reverse order.
MAINTENANCE WARNING: DISCONNECT ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES BEFORE CLEANING OR SERVICING. WARNING: HOT GLASS, GREASE, AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING AND SERVICING THE OVEN. TROUBLESHOOTING PROBLEM POSSIBLE CAUSE 1. Control does not light up. 1. ON-OFF switch is not pressed ON. 2.
