OPTIMUM OPERATION
7.
Observe the following precautions to ensure the
system operates.
Adjust the room temperature properly for a com-
•
fortable 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, air will escape and
diminish cooling or heating operation.
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 elec-
tricity is being used even if the system is not
operating. Turn off the main power supply switch
for saving energy. When reoperating, turn on the
main power supply switch 6 hours before opera-
tion for smooth running (Refer to MAINTE-
NANCE).
When the display shows “Time to clean fi lter”,
•
ask a qualifi ed service person to clean the fi lters
(Refer to MAINTENANCE).
