both the hot water module and outdoor units to the OFF position. Otherwise, electric shocks may result.
Before opening the front panel of the hot water module or service panel of the outdoor unit, set the circuit
breaker to the OFF position.
Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with the
interior parts.
Only a qualified installer (*1) or qualified service person (*1) is allowed to remove the electrical parts box cover
of the hot water module or service panel of the outdoor unit and do the work required.
