NERGY SAVING AND OPTIMUM
OPERATION
Observe the following precautions to ensure the system operates
properly.
Adjust the air outlet properly and avoid direct air flow to room
inhabitants.
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 often.
Extended use requires special attention to ventilation.
Keep doors and windows closed. If the doors and windows
remain open, air will flow out of your room causing a decrease in
the cooling or heating effect.
Be careful not to cool or heat too much. To save energy, keep
the temperature setting at a moderate level.
