WARNING
Be sure to comply with local codes while run-
ning the wire from the indoor unit to the outdoor
unit (size of wire and wiring method, etc. ).
Every wire must be connected firmly.
No wire should be allowed to touch refrigerant
tubing, the compressor or any moving part.
Loose wiring may cause the terminal to over-
heat or result in unit malfunction. A fire hazard
may also exist. Therefore, be sure all wiring is
tightly connected.
Connect wires to the matching numbers of ter-
minals.
NOTE:
• Connector trade size for this unit is 1/2” (12.7 mm). The connector
can be bought at a hardware store. Refer to “How to connect wir-
ing to the terminals” for instructions on connecting depending on
the wire type you are using.
• The fuse located in the outdoor unit provides power supply pro-
tection and may blow when power is applied if the system has
been incorrectly wired.
