outdoor unit. Line 2 shall be a continuous wire with no splices between the indoor and outdoor
unit.

maintenance to avoid risk of electric shock or damage to equipment.
8. Terminal 2 carries communication signals and should not be cut or spliced.

communication errors, do not connect the ground wire to the terminal block from any other
location.
