Whirlpool WED9470WW Installation Instructions - Page 6

■ To supply the required 3 or 4 wire, single phase, 120/240 volt, 60 Hz., AC only electrical supply (or 3 or 4 wire, 120/208 volt electrical supply, if specified on the serial/rating plate) on a separate 30-amp circuit, fused on both sides of the line. A timedelay fuse or circuit breaker is recommended. Connect to an individual branch circuit. Do not have a fuse in the neutral or grounding circuit. ■ Do not use an extension cord. ■ If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate. Electrical Connection To properly install your dryer, you must determine the type of electrical connection you will be using and follow the instructions provided for it here. ■ This dryer is manufactured ready to install with a 3-wire electrical supply connection. The neutral ground conductor is permanently connected to the neutral conductor (white wire) within the dryer. If the dryer is installed with a 4-wire electrical supply connection, the neutral ground conductor must be removed from the external ground connector (green screw), and secured under the neutral terminal (center or white wire) of the terminal block. When the neutral ground conductor is secured under the neutral terminal (center or white wire) of the terminal block, the dryer cabinet is isolated from the neutral conductor. ■ If local codes do not permit the connection of a neutral ground wire to the neutral wire, see "Optional 3-wire connection" section. ■ A 4-wire power supply connection must be used when the appliance is installed in a location where grounding through the neutral conductor is prohibited. Grounding through the neutral is prohibited for (1) new branch-circuit installations, (2) mobile homes, (3) recreational vehicles, and (4) areas where local codes prohibit grounding through the neutral conductors. If using a power supply cord: Use a UL listed power supply cord kit marked for use with clothes dryers. The kit should contain: ■ A UL listed 30-amp power supply cord, rated 120/240 volt minimum. The cord should be type SRD or SRDT and be at least 4 ft (1.22 m) long. The wires that connect to the dryer must end in ring terminals or spade terminals with upturned ends. ■ A UL listed strain relief. If your outlet looks like this: 4-wire receptacle (14-30R) Then choose a 4-wire power supply cord with ring or spade terminals and UL listed strain relief. The 4-wire power supply cord, at least 4 ft (1.22 m) long, must have four 10-gauge copper wires and match a 4-wire receptacle of NEMA Type 14-30R. The ground wire (ground conductor) may be either green or bare. The neutral conductor must be identified by a white cover. If your outlet looks like this: Then choose a 3-wire power supply cord with ring or spade terminals and UL listed strain relief. The 3-wire power supply cord, at least 4 ft (1.22 m) long, must have three 10-gauge copper wires and match a 3-wire receptacle of NEMA Type 10-30R. 3-wire receptacle (10-30R) If connecting by direct wire: Power supply cable must match power supply (4-wire or 3-wire) and be: ■ Flexible armored cable or nonmetallic sheathed copper cable (with ground wire), protected with flexible metallic conduit. All current-carrying wires must be insulated. ■ 10-gauge solid copper wire (do not use aluminum) at least 5 ft (1.52 m) long. Electrical Connection WARNING Fire Hazard Use a new UL listed 30 amp power supply cord. Use a UL listed strain relief. Disconnect power before making electrical connections. Connect neutral wire (white or center wire) to center terminal (silver). Ground wire (green or bare wire) must be connected to green ground connector. Connect remaining 2 supply wires to remaining 2 terminals (gold). Securely tighten all electrical connections. Failure to do so can result in death, fire, or electrical shock. 1. Disconnect Power. 6
