5. Troubleshooting
Since the inverter air conditioner is equipped with Electrical control circuits at both Indoor &
outdoor unit, the trouble shooting shall be performed according to the error mode.
Inside the controller of the outdoor unit (inverter), the large capacity of electrolytic condenser so
that it takes the time to discharge after the power off since the electrical charge re m a i n s
(the charging voltage DC 340V).
Take care of the electrical shock by contact on the charging part before the discharge after the
power off. (It takes approximately 2 minutes to discharg e ) .
5-1 Basic items for trouble shooting
1) Is the power source pro p e r ?
The power source shall be in the range of the rated voltage ? 1 0 %. If it is out of this range, it may
cause the abnormal operation.
2 ) Is the connection made between the indoor and outdoor unit?
The connection between indoor and outdoor unit shall be performed with 4 wire. (connection
cable of indoor and outdoor unit + ground wire ) .
3) The phenomena as follows are not out of ord e r.
