PTIMUM 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.
Keep doors and windows closed. If the doors and windows
remain open, room air will flow out and decrease the effect of
cooling and heating.
Never place objects near the air inlet and the air outlet of the
unit. It may retard effectiveness or cause operation to stop.
Turn off the main power supply switch when not using for long
periods of time. Electricity is consumed as long as the switch is
on. Turn off the main power supply switch in order to save
energy. Turn on the main power supply switch 6 hours before
restarting operation in order to ensure smooth operation. (Refer
