●
Outdoor unit check points
Check items with the *mark when the power is ON.
Noise filter check:
There should be continuity.
There should be no shorts between phases.
Resistance check:
Resistance is measured
(15Ω)
DC Reactor contiuity
check:55mΩ or less
Capacitor check:
Check for anomaly in appearance
such as damage,swelling,etc.
