Observe the following precautions to ensure the system operates.

• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or cooling.

• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.

• Ventilate the room regularly.

Using the unit for long periods of time requires attentive ventilation of the room.

• Keep doors and windows closed. If the doors and windows remain open, room air will flow out and cause to decrease the effect of cooling and heating.

They may deform due to the heat.

• Never place objects near the air inlet and the air outlet of the unit. It may cause deterioration in the effect or stop in the operation.

• Turn off the main power supply switch when it is not used for long periods of time. When the main power switch is turned on, some watts of electricity is being used even if the system is not operating.
