procise way the main malfunctions which may concern the air conditioner.
3-minutes' delay protection: there is a protective control of the Outdoor Unit, to prevent
compressor's damages after stops. This control is effective in case of malfunction, power failure,
turning off the system, etc. and it does not allow Outdoor Unit to restart before 3 minutes have
elapsed since the Unit stopped. During this time, Indoor Unit cannot run.
AUTORESTART AFTER A POWER FAILURE
• When a power failure occurs during operation, the air conditioner immediately stops.
• When power is restored, “OPERATION” lamp starts blinking. In particular, the air conditioner
will automatically restart after 3 minutes have elapsed since power is restored. This means that
it is not required to press “ON/OFF” button on the remote controller. The settings will be the
same as before the blackout.
“AUTO CLEAN” FUNCTION
In COOL or DRY mode, press “AUTO CLEAN” button on remote controller to select self-clean
operation of air conditioner.

to keep it for next operation of the air conditioner, you only need to press “ON/OFF” button on remote
control. Set temperature and fan speed settings will be memorized too, so they will be the same at
next restart of the air conditioner.
It is possible to change operation mode while the air conditioner is operating. However, the Unit will
not immediately start operating according to the new mode, but a little delay is needed for carrying
out a test and choosing new operating parameters.
