Caution

The appliance is phase-sensitive. It is absolutely essential to connect the mains phase (L) to the phase of the appliance, and the mains neutral (N) to the neutral of the appliance.

Caution

There may be no potential difference between neutral (N) and earth (). If this is the case, then an isolating transformer must be applied in the supply circuit (3.10.4 "Isolating transformer").

For more information or to order this isolating transformer, please contact A.O. Smith water Products Company.

The figure shows a view of the electrical connector block, and the table shows the appropriate connections.
