NOTE
When other electric appliances are used at the same time, to avoid triggering the circuit breaker, power saving mode
is recommended. Of course you can use power saving mode to save energy as well.
Power saving mode consumes less energy, but may not heat / cool the room as much as normal mode. (The
maximum current is limited to approximately 75 % (factory default) of the normal mode.)
To adjust the power-save settings, see "To configure the power saving settings" in Power saving mode.
Even when operation start / stop, operation mode change, or power reset is performed during the power saving mode,
the power saving mode is retained until the next operation.

NOTE
For environmental conservation, it is strongly recommended that the indoor and outdoor units of the air conditioner in
use be cleaned and maintained regularly to ensure efficient operation of the air conditioner.
When the air conditioner is operated for a long time, periodic maintenance (once a year) is recommended.
Furthermore, regularly check the outdoor unit for rust and scratches, and remove them or apply rustproof treatment, if
necessary.
As a general rule, when an indoor unit is operated for 8 hours or more daily, clean the indoor unit and outdoor unit at
least once every 3 months. Ask a professional for this cleaning / maintenance work.
Such maintenance can extend the life of the product though it involves the owner's expense.
Failure to clean the indoor and outdoor units regularly will result in poor performance, freezing, water leakage, and even
compressor failure.
