Field Conversion from 3-phase to 1-phase Operation

A standard 3-phase operation dishwasher can be converted for

1-phase operation with the installation of a jumper wire on the main terminal and rewiring of the wash tank and booster tank heaters.

A jumper wire, jumper bars and a new data plate are stowed on top of the wash tank heater junction box.

To convert the dishwasher from 3-phase to 1-phase operation:

Install Main Terminal Block Jumper Wire
