procedures for grounding the outdoor unit, mast, lead-in wire, and discharge unit, size of grounding
conductors, and connection requirements for grounding electrodes. Other regulations may apply in
different countries and therefore it is recommended that installation of the outdoor unit be contracted to
a professional installer.

of the country of use.
Powering down before servicing
