( i ) Every time AIR DISCHARGE button is pressed, setting will be changed .
( ii ) Airflow direction can be changed with AIR DISCHARGE button.
When 60° or 70° discharge is selected with the low fan speed in COOL operation, “AUTO RETURN” will appear below the
temperature display. One hour later, the discharge direction returns to 10° automatically and “AUTO RETURN” will disap-

(4) Detecting abnormalities in the outdoor unit
After the compressor has been continuously operated for 3 minutes, if the difference between the indoor coil temperature
and room temperature is out of RANGE C for 1 minute, the indoor fan speed will turn to low. Five minutes later, if the differ-
ence is still out of
RANGE C,the outdoor unit is functioning abnormally. Thus, the compressor stops and check code “P8” appears on remote
controller.
RANGE A : Pipe temperature is more than 9 degrees above room temperature.
RANGE B : Pipe temperature is within 9 degrees either way of room temperature.
RANGE C : Pipe temperature is more than 9 degrees below room temperature.
