enclosure.
A knock-out hole is provided to permit use
of conduit or metal-clad cable connectors.
CAUTION! Label all wires prior to disconnection
when servicing controls. Wiring errors can cause
improper and dangerous operation.
VERIFY PROPER OPERATION AFTER SERVICING!
The maximum current draw is

The water heater must be electrically
grounded in accordance with local codes,

accordance with latest edition of the
