For safe, reliable operation in Standby mode, it is important to
follow a few guidelines:
D Never plug the unit in to the power source with the main switch

source.
D The circuit breaker and extension cable used for Standby
operation should conform to the following:

licensed electrician should be contracted. A licensed electrician is

area and can ensure that the circuits are properly designed and
installed, and that connections are correct.
