1. Handle the fan box with care. If the front or the bottom panel becomes damaged, water or dust may enter the fan box, dam-
aging its internal parts.
2. Perform the service after disconnecting the fan board connector (CNINV) and the connect board connector (CN103).
Before plugging in or unplugging connectors, check that the outdoor unit fan is not rotating and that the voltage be-
tween FT-P and FT-N on the INV board or between SC-P and SC-N on the capacitor board is 20 VDC or less. The ca-
pacitor may collect a charge and cause an electric shock when the outdoor unit fan rotates in windy conditions.
3. Reconnect the connector (CNINV) back to the fan board and reconnect the connector (CN103) back to the connect board
after servicing.
