Installation, Operation and Care of MODEL HR5E & HR7E ROTARY OVENS SAVE THIS MANUAL FOR FUTURE REFERENCE GENERAL The HR5E and HR7E Ovens are five-spit and seven-spit rotary ovens that feature a full view tempered glass door and quartz lighting that promote visual appeal and stimulate customer interest. The solid back model (HR7E only) is used when the oven is positioned against a wall.
INSTALLATION Immediately after unpacking the oven, check for possible shipping damage. If the oven is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Prior to installation, test the electrical service to assure that it agrees with the specifications on the machine data plate located behind the left-hand hinged door. LOCATION The oven must be installed on a level surface.

BEFORE FIRST USE WARNING: DISCONNECT ELECTRICAL POWER SUPPLY TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES BEFORE CLEANING OR SERVICING. Oven must be burned in to release any odors that might result from heating the new oven surfaces. 1. Clean oven and accessories, both inside and outside. Refer to CLEANING, pages 25 — 39, for further instructions. 2. Operate oven at maximum temperature setting of 482°F (250°C) for 45 minutes.
PLACING THE ROTOR IN THE OVEN (HR7E) The rotor must properly engage with the drive mechanism. Orient the rotor so that the end plate with square drive slots is on the same side of the oven as the drive arm. STEP 1: Stop the drive arm so it is in the down position (Fig. 3). Fig. 3 STEP 2: Place the rotor shaft onto upper notch of support bearing on the non-drive side of the oven (Fig. 4). Fig. 4 STEP 3: Place the drive side of the rotor shaft on the drive arm support notch (Fig. 5). Fig.

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 (HR5E) Press pointed ends of spits into whole poultry so points go through the chest-wing and leg-thigh regions (Fig.10). Load three or four chickens on each fork spit. Fig. 10 LOADING — CHICKENS ON RACKS (HR5E) Place chicken cavity over spindle, legs down, neck up and breast forward (Fig. 11). Fold and cross legs; hook leg ends under side rods of rack. Break wings at top joint; fold wings behind bird.
WARNING: SPITS ARE SHARP. USE CARE WHEN LOADING PRODUCT. SPITTING — CHICKENS ON FORK SPITS (HR7E) Press pointed ends of spits into whole poultry so points go through the chest-wing and leg-thigh regions (Fig. 14). Load four or five chickens on each fork spit. Fig. 14 SPITTING — CHICKENS ON THERMO-WAVE SPITS (HR7E) 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 (HR5E) 1. Place pointed end of V-spit into outside hole on drive side of rotor (Fig. 19). 2. Fit notched end of V-spit into appropriate holes on non-drive side of rotor (Fig. 18). 3. Make sure the spit is level. If the spit is not level, you might be using the wrong holes.

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 THE ELECTRICAL POWER SUPPLY 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. Do not hose down. CAUTION: Do not clean with a high pressure hose. Cleaning — Grease Drawer and Oven Interior / Exterior 1. Empty grease drawer (refer to page 24). 2.
CLEANING STAINLESS STEEL SURFACES 1. Wash stainless steel parts with warm soapy water. 2. Rinse parts thoroughly. 3. Dry with a soft clean cloth. 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.
CLEANING QUARTZ LAMPS CAUTION: Do not clean the quartz lamps in the top of the oven with soap and water. Be very careful when cleaning lamps. Lamps can be broken by mishandling. • Clean lamps with a cloth soaked in alcohol. • Do Not touch lamps with your bare hands. Touching the quartz lamp could shorten the life of the bulb. CLEANING THE TEMPERATURE PROBE (Optional Accessory) Clean after every use. 1. Remove the probe from the probe holder. 2. Unplug probe cord from the probe holder (if needed). 3.
