INSTALLATION
Outdoor Unit - Wiring
WARNING
• Follow safe procedures to shut off the breaker of the outdoor/indoor unit prior to performing any and all
electrical work. For the outdoor unit please allow 3 minutes before working on the electrical, as the inverter
boards capacitor must discharge. (Risk of personal injury can occur if not followed)
• Make sure that the indoor and outdoor fans have stopped completely before performing electrical work or
reaching into the equipment.
• Protect the wires, electrical parts, etc. from small animals as well as lizards and ants. If not protected,
damage to the electrical system or fire could occur.
• Prevent the wiring from touching refrigerant pipes, plate edges, and electrical parts inside the unit.
• Install an ELB (Electric Leakage Breaker) at the power source. If ELB is not used, it can cause electric shock
or fire.
• This unit utilizes an inverter, which means that protections must be made to ensure harmonics in the electri-
cal system are maintained, as well it is recommended that a surge protector be installed inline to protect the
electrical components.
• The use of temporary connection wires, stranded wires, extension cables or control line connections, is
prohibited. The use of such connections may cause electric shock or fire.
The tightening torque of each screw shall be as followed.
M4: 0.7 to 1.0 ft.lb (1.0 to 1.3 N·m)
M5: 1.5 to 1.8 ft.lb (2.0 to 2.5 N·m)
M6: 3.0 to 3.7 ft.lb (4.0 to 5.0 N·m)
M8: 6.6 to 8.1 ft.lb (9.0 to 11.0 N·m)
M10: 13.3 to 217 ft.lb (18.0 to 23.0 N·m)
Proper torquing of fasteners ensures not only safe and reliable operation but lower risk of ARC or fire.

Check to make sure that live electrical parts (i.e. terminals, exposed wires, etc.) are not
contacting ground. THere should be an electrical resistance of 2 MegOhms between live parts
and ground. If it is determined that there is a short to ground, do not operate the system until
the source of the problem is identified and corrected.
