Instructions for Conversion of Commercial Electric Models

Electrical Phase Conversion Electrical phase conversion will require a change from single-phase to three-phase or an opposite
conversion change from three-phase to single-phase. Each of these conversions will be explained
separately as follows:

Example of finished Single Phase construction.
(All connections are to be made on the LOAD side of the terminal block)
1. Disconnect blue wire and yellow wire from terminal L-3 of the terminal block.
2. Connect yellow wire to terminal L-1 of the terminal block. The black wires should remain connected
to L-1 of the terminal block as it was originally manufactured.
3. Connect blue wire to terminal L-2 of the terminal block. The red wires should remain connected to
L-2 of the terminal block as it was originally manufactured.
4. Field wiring for the water heater power supply will eventually be connected to the line terminals L-1
and L-2 of the terminal block when the product is installed.
(All connections are to be made on the LOAD side of the terminal block)
1. Disconnect yellow wire from terminal L-1 of the terminal block
2. Disconnect blue wire from terminal L-2 of the terminal block
3. Connect both blue and yellow wires to L-3 of the terminal block
4. Field wiring for the water heater power supply will eventually be connected to the line terminals L-1,
L-2, and L-3 of the terminal block when the product is installed.
