What is “ECONO COOL”?
Swing air flow (change of air flow) makes you feel cooler than constant air flow. So, even though the set temperature is
automatically set 2°C higher, it is possible to perform cooling operation with keeping comfort. As a result, energy can be saved.

USED FOR A LONG TIME
When it is not going to be used for a long
time:
1 Perform the FAN operation for 3 or 4 hours
to dry the inside of the air conditioner.

ler to the highest temperature in the MANUAL COOL
mode. (Refer to page 7.)
2 Turn off the breaker and/or disconnect the
power supply plug.
CAUTION:
Turn off the breaker or disconnect the power supply plug
when the air conditioner is not going to be used for a
long time.
Dirt may collect and this may cause a fire.
3 Remove the batteries from the remote con-
troller.
CAUTION:
To prevent liquid leakage, take out all batteries when the
remote controller is not going to be used for a long time.
