What electrical requirements are needed to install the WFW9400SW00 washing machine?

A 120 volt, 60 Hz., AC only, 15- or 20-amp, fused electrical supply is required. The washer must be plugged into a grounded 3-prong outlet located within 6 feet (1.8 m) of where the power cord is attached to the back of the washer. A time-delay fuse or circuit breaker is recommended, and it is recommended that a separate circuit serving only this appliance be provided.
