CAUTION (AOH24LMAM2)
There is a mistake printed in "LABEL WIRING", which is on the back of
Top Plate in outdoor unit.
When you reconnect this model you should do as the correct "CIRCUIT DIAGRAM" shows,
which is in this service manual.
See the next page. It's the correct "CIRCUIT DIAGRAM".
It's better to take away incorrect "LABEL WIRING" from outdoor unit,
and put correct "CIRCUIT DIAGRAM" on it.
NOTE
Incorrect "LABEL WIRING" is on the serial No.T000001 to T001020 of AOH24LMAM2.
If you reconnect as it shows, two indoor units go like below.
When you turn on indoor unit A and turn off B,
indoor unit A blows, but it doesn't make you cool or warm.
indoor unit B makes itself cool or warm, but it doesn't blow.
When you turn off indoor unit A and turn on B,
indoor unit A makes itself cool or warm, but it doesn't blow.
indoor unit B blows , but it doesn't make you cool or warm.
