To avoid backfeeding into utility systems, isolation of the
residence electrical system is required.
Before temporary connection of the generator to the
residence electrical system, turn off the main
service/disconnect.
If your generator is to be used as a stand-by power source
in case of utility power failure, it should be installed by a
registered electrician and in compliance with all applicable
local electrical codes.
Proper use requires that a double throw transfer switch be
installed by a licensed qualified electrician so that the
building's electrical circuits may be safely switched between
utility power and the generator's output, thereby preventing
backfeed into the power utility's electrical system.
Always follow local codes and regulations that apply to
the installation of any item that concerns this product.

English
To avoid backfeeding into utility systems, isolation of
the residence electrical system is required. Before
temporary connection of a generator to the residence
electrical system turn off the main switch. Before
making permanent connections a double throw
transfer switch must be installed. To avoid
electrocution or property damage, only a trained
electrician should connect generator to residence
electrical system. California law requires isolation of
the residence electrical system before connecting a
generator to residence electrical systems. Temporary
connection not recommended due to backfeeding.
INSTALLATION INSTALLATION
To avoid possible personal injury or equipment
damage, a registered electrician or an authorized
service representative should perform installation and
all service. Under no circumstances should an
unqualified person attempt to wire into a utility
circuit.
