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

1.Disconnect all power to the machine.

2.Remove the top-mounted control cabinet cover and locate the main terminal block located in the left-rear corner of the cabinet.

3.Connect the jumper wire (shipped inside the control cabinet) between L2 and L3 on the output side of the main terminal block.

4.Connect the 1-phase incoming power supply to L1 and L2 on the input side of the main terminal block.

Rewire Wash Tank Heater Element for 1PH

1.Remove the lower front panel.

2.Remove the wash tank heater junction box cover.

3.Remove the paper insulator and jumper bars from the heater terminals.

4.Additional short jumper bars are stowed with the new data plate.

5.Reposition the jumper bars for 1PH as shown below.

6.Connect the #33 wire to one element terminal as shown.

7.Connect the #34 and #35 wires to the other terminals as shown.

8.Reinstall the paper insulator and the junction box cover.
