and local codes and ordinances. There must be enough
wiring from the fused disconnect (or circuit breaker) box to

For optional power supply cord kit installations, follow the
instructions in the "Make Electrical Connection" section.
NOTE: Do not reconnect power until the installation is
complete.

terminal box cover and set aside.

the vent hood (depending on the incoming location of your
home power supply cable), and install a UL listed or CSA
approved " strain relief.
