1 ELECTRICAL REQUIREMENTS WARNING This appliance must be properly grounded. WARNING All new constructions, mobile homes, recreational vehicles and installations where local codes do not allow grounding through neutral, require a 4-conductor UL-listed range cord. WARNING To prevent fire or shock, do not use an extension cord with this appliance. WARNING To prevent shock, remove house fuse or open circuit breaker before beginning installation. We recommend you have the electrical wiring and hookup of your range connected by a qualified electrician. After installation, have the electrician show you how to disconnect power from the range. You must use a single-phase, 120/208 VAC or 120/240 VAC, 60 hertz electrical system. If you connect to aluminum wiring, properly installed connectors approved for use with aluminum wiring must be used. Effective January 1, 1996, the National Electrical Code requires that new construction (not existing) utilize a 4-conductor connection to an electric range. When installing an electric range in new construction, mobile home, recreational vehicle, or an area where local codes prohibit grounding through the neutral conductor, refer to the section on four-conductor branch circuit connections. Check with your local utilities for electrical codes which apply in your area. Failure to wire your oven according to governing codes could result in a hazardous condition. If there are no local codes, your oven must be wired and fused to meet the National Electrical Code, NFPA No. 70 - latest edition, available from the National Fire Protection Association. This appliance must be supplied with the proper voltage and frequency, and connected to an individual, properly grounded, 40 amp (minimum) branch circuit protected by a circuit breaker or time-delay fuse. Use only a 3-conductor or a 4-conductor UL-listed range cord. These cords may be provided with ring terminals on wire and a strain relief device. A range cord rated at 40 amps with 125/250 minimum volt range is required. A 50 amp range cord is not recommended but if used, it should be marked for use with nominal 13»8" diameter connection openings. Care should be taken to center the cable and strain relief within the knockout hole to keep the edge from damaging the cable. The rating plate is located on the oven frame or on the side of the drawer frame. NOTE: Use of automatic, wireless or wired external switches that shut off power to the appliances, are not recommended for this product. SINGLE OVEN Rating plate 2 POWER CORD AND CONDUIT INSTALLATION A Remove terminal block cover (on the back of range) by removing screws using a 1/4" nut driver. Do not discard these screws. Back of range Screw to remove terminal block cover Terminal block cover B For power cord and 1" conduit only, remove C the knockout ring (13»8") located on bracket directly below the terminal block. To remove the knockout, use a pair of pliers to bend the knockout ring away from the bracket and twist until ring is removed. Terminal block (appearance may vary) For power cord installations only (see the next step if using conduit), assemble the strain relief in the hole. Insert the power cord through the strain relief and tighten. Allow enough slack to easily attach the cord terminals to the terminal block. If tabs are present at the end of the winged strain relief, they can be removed for better fit. NOTE: Do not install the power cord without a strain relief. The strain relief bracket MUST be installed before reinstalling the rear range wiring cover. Knockout ring in bracket Strain relief Terminal block Knockout ring removed Power cord Bracket D For 3/4" conduit installations only, purchase a squeeze connector matching the diameter of your conduit and assemble it in the hole. Insert the conduit through the squeeze connector and tighten. Allow enough slack to easily attach the wires to the terminal block. NOTE: Do not install the conduit without a squeeze connector. The squeeze connector MUST be installed before reinstalling the rear terminal block. Squeeze connector Terminal block Proceed to step 4 or 5. Conduit Bracket
