8. Troubleshooting
8.1Safety
Because there are high power capacitors on PCB and related circuits in outdoor unit, even after
shutting down the power supply, risk of electrocution still exists. Do not forget to discharge the electrical
power in these capacitors.
Use a 25~40 W bulb or resistor with resistance value of about 1500 ohm to 2000 ohm to discharge the
power in the capacitors.

Electrolytic Capacitors
(HIGH VOLTAGE! CAUTION!)
The voltage in P3 and P4 in outdoor PCB is high voltage about 310V
The voltage in P5 and P6 in outdoor PCB is high voltage about 310V
