■

All wiring must be performed by an authorized
electrician.

■

All field supplied components and all electric
construction should comply with the applicable local
and national codes.

To persons in charge of electrical wiring work:

Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
