- Set suitable indoor temp. Too hot and too cold do no good to your health. Set a temp you feel comfortable.- Use TIMER properly. Do not expose yourself to direct cold-airflow for too long when sleeping in summer.- Keep doors and windows shut tightly. Avoid wasting of energy to raise cooling or heating effect.- Adjust airflow direction properly. Usually set airflow upwards at cooling and downwards at heating to get uniform room temperature.- Ventilate open. Ventilate the room for 1 to 2 munutes every 1 hour for health’s sake specially an oil bumer is used inside.- Clean the air filter regularly. Dirty filter will decrease efficiency, generate noise and waste electricity. Better to clean it every two

weeks.
