• Because of the protective mechanism, the appliance does not start
operating immediately to keep the unit from overloading. The air
conditioner will start in 3 minutes.

change the set temperature. Press the Temperature button to decrease
or increase the temperature.

minutes. Cool air does not come out to protect the compressor of the
outdoor unit.
• Check if the air conditioner is installed in a place with a direct exposure
to sunlight. Hang curtains on windows to boost cooling efficiency.
• Check if the cover or any obstacle is not near the outdoor unit.
• Check if the refrigerant pipe is too long.
• Check if the air conditioner is only available in Cool mode.
