INSTALLATION PRE-INSTALLATION Uncrate the broiler, and inspect for shipping damage. Contact the factory if there is obvious damage. Remove the tape securing the machine parts, and install the parts in their proper location. Refer to the Parts and Location section of this manual. If you find concealed damage to any part of this unit, contact your freight carri- er immediately. The factory warranty does not cover freight damage. MOUNTING If the broiler was shipped with a tubular stand, refer to separate tubular stand assembly instructions. Note: The four legs of the broiler stand are equipped with casters. Always set the brakes on the cast- ers to prevent the broiler from shifting during operation or cleaning. Adjust the legs on the broiler and the stand so that the broiler is level. HOOD REQUIREMENTS This appliance must be installed under a ventilation hood of adequate size and capacity: Model 1424 or 1450 800 CFM (1020 CMH) Model 1430 or 1435 600 CFM (760 CMH) The hood should be at least 6" (15.2 cm) larger in all dimensions than the appliance top, and be 12" to 18" (30.5 cm - 45.7 cm) above the top. Do not obstruct the flow of combustion and ventilation air. An adequate air supply must be available for safe and proper operation. Note: See the National Fire Prevention Association booklet on ventilation of cooking equipment. Write to: NFPA, 470 Atlantic Ave., Boston, MA 02210. Local codes on venting must also be complied with. CLEARANCE For proper installation, the minimum clearance from combustible and non-combustible construction is 6" (15.2 cm) from the back and 6" (15.2 cm) from the front of the machine. Keep appliance area free from com- bustibles. To facilitate disassembly and service of the unit a minimum of 24" (61 cm) should be allowed on the front of the broiler as well as the left side. ELECTRICAL CONNECTION Power requirements are stated on the unit nameplate and must be connected accordingly. Before starting broiler, tighten all electrical connections in control box.

Broil Stabilizer Control Top Number = Actual Temperature Bottom Number = Set Temperature D. Bun Platen Thermostat E. Main Power On/Off Switch F. 5-Amp Fuse G. Main Power Indicator Light (Red) CALIBRATING THE BROIL STABILIZER CONTROL The 1424/1450 & 1430/1435 Electric broilers are equipped with a Broil Stabilizer Control that senses when the broiler is cooking, and increases the temperature when in use. Refer to calibration instructions in this manual or on the metal label plate on the control box of the broiler. The red light on the control may flash during normal operation. No daily adjustment of the Broil Stabilizer Control is necessary. FOOD PRODUCT SAFETY The Nieco broiler is designed to cook food consistently. Careful setting of the conveyor belt speed is necessary for proper performance. Always test the product to be sure it is cooked properly every day. Follow established guidelines for food safety and handling. 5 BROIL TEMPERATURE STABILIZER CONTROL Electric broilers are equipped with a Broil Temperature Stabilizer Control that senses when the broiler is being used, and adjusts the temperature to keep the broiler hot during heavy use. The control consists of two parts - a temperature probe to sense the internal temperature of the broiler, and the control itself. CALIBRATING THE BROIL STABILIZER CONTROL In order to assure proper operation, the Broil Stabilizer Control must be calibrated for operation in the restaurant. Every broiler will calibrate slightly differently, depending on supply voltage, ventilation, etc. Follow these step by step instructions when the broiler is new, and once per month after. Step 1: Be sure all pieces of the broiler are in place. Make sure the broiler is plugged in and the exhaust hood is turned on. Turn the broiler on by turning the main power switch to the right. Turn on the conveyor belts using the motor breaker switch. Step 2: Set the temperature (bottom number) to 200° F. Use the up or down arrows on the con- trol to set the temperature. The bottom number is the set temperature and the top num- ber is the actual temperature. Step 3: Allow the broiler to heat up for 40 minutes. During this time, the actual temperature will climb. Wait until the actual temperature stabilizes before proceeding. Step 4: Set the ATC (bottom number) to 200° F higher than the actual temperature. For exam- ple, if the broiler stabilizes at 700° F, then the proper setting should be 900° F. WARNING The broiler can be damaged if this control is not set according to instructions. TROUBLE SHOOTING ERROR MESSAGES Message Action ER 4 Turn power on and off several times. If the message remains, replace control. If the message disappears, the control may need to be reprogrammed. Call Nieco or your local distributor for instructions. ER 6 Cycle power on and off several times. If message remains, replace temperature probe (P/N 4073). 6 Before starting broiler, be sure that all parts are installed in the proper location, and the ventilation hood is turned on.

CLEANING INSTRUCTIONS DAILY CLEANING Clear broiler of all food product before shutting down to clean. Allow broiler to cool before handling parts. 1. SHEET METAL PARTS. Remove all trays, drip pans, stripper blades, reflectors, and side panels. Wash with water and an approved detergent. Sanitize. 2. SHAFTS. Clean the drive shafts with the special tool provided. 3. BUN PLATEN. Clean and sanitize the teflon sheets daily. Do not spray anything on the control box. WEEKLY CLEANING 1. Clean the frame of the broiler as necessary to remove grease build up. E. PERIODIC MAINTENANCE Note: Maintenance should be performed by authorized personnel only. Always disconnect the power before performing any maintenance on the broiler. Check the heating elements periodically for signs of wear. Rotating the top and bottom elements every 6 months will increase the life of the elements, and improve the performance of the broiler. The motor uses carbon brushes that will eventually wear out. Replace the brushes if there is excessive noise or erratic performance from the motor. Variations in supply voltage can affect the temperature of the broiler. Overfired elements can cause performance problems and warping. Heating elements are available in different voltages, so adjustments to cooking perfor- mance are made by using different voltage elements. Contact your distributor for more information. Always keep the control box clean and free of grease. Do not spray anything on the controls. 14 F. CONVEYOR BELT REMOVAL Before beginning, notice the way the belt runs through the broiler. Also notice the direction the knuckles face. Be sure to re-assemble in the same way. 1. Run belt until the Master Link is 1 near the front idler shaft. 2. Lift shaft and Teflon Blocks up, 2 3 and slide the blocks out. 3. Unhook the Master Link. To reassemble, reverse the procedure. Be sure to reassemble the belt with the knuckle opening facing away from the direction of travel. 15 G. CONVEYOR BELT TENSION Maintain proper tension on the conveyor belts to prevent jamming. Bearing spacers (pictured below) are supplied with the broiler to make minor tension adjustments. Major tension adjustments are made by removing a link or links from the belt. The diagram on the left shows the spacer in the stored position. The diagram on the right shows the spacer behind the teflon bearing tightening the belts. Belt tension should be checked monthly. To do this, allow the machine to cool, then grip the idler shaft at each end and pull on it. If the shaft and bearings move 3/16” or more, the spacers should be placed behind the bearings to tighten the belts. If the spacers are already behind the bearings, return them to the stored position and remove a link from the conveyor belt. BROIL BELT PROBLEMS Interference with stripper blade: The most common belt problem to be expected is the physical interference of the belt with the stripper blade. This is caused by bent or warped rods, or loose belt, and can be fixed by replacing the rods that are causing the problem. Other causes are bent stripper blades, or utensils jammed in the belt. Blocked belts: When trouble shooting drive problems, it is important to ensure that the belt is not being blocked. To do this, detach the drive chain and turn the meat belt by hand. The belt, with the motor detached, should turn freely and easily. If the blockage has occurred which is preventing the belt from turning, the block- age should be removed before the drive chain is re-attached. The drive chain can be easily removed from the drive sprocket (on the motor shaft) by loosening the mounting bolts and raising the motor. 16 H.
