terminal tap is marked for 208 volts use this tap for measured voltage of 200 volts - 215 volts. and the
other tap is marked 230 volts for 216 volts - 240 volts. Note: All washers have a controls transformer.
Always check the incoming voltage and use the appropriate transformer terminal when installing ALL
washers.
