Code (NEC).
(2) Check to ensure that the power supply voltage is within ±10% of the rated voltage.
(3) Check the capacity of the electrical wires.
If the power supply capacity is too low, the system cannot be started due to the voltage drop.
(4) Check to ensure that the ground wiring is connected.

Do not operate the system until all check points have been cleared.
(A) Check to ensure that the electrical resistance is more than 1 megohm, by measuring the resistance
between ground and the terminal of the electrical parts. If it is less than 1 megohm, do not operate
the system until the electrical leakage is found and repaired.
(B) Check to ensure that the stop valves of the outdoor unit are fully opened, and then start the system.
(C) Apply power to the outdoor unit(s) at least 12 hours prior to operation of the system for preheating
of the compressor oil.
x
Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and
the pipes at the discharge side are heated to higher than 194
