let the filter dry in direct
sunlight.

Repairing Refrigerant Leaks
WARNING
•
If the refrigerant leaks, turn off the air
conditioner and any combustible heating
devices, ventilate the room and call your
dealer immediately. Refrigerant is both toxic
and flammable.
DO NOT
use the air
conditioner until the leak is repaired.
•
When the air conditioner is installed in a
small room, measures must be taken to
prevent the refrigerant concentration from
exceeding the safety limit in the event of
refrigerant leakage. Concentrated
refrigerant causes a severe health and safety
threat.
Refrigerant Leak Detection System
(some models)
•
In the event of a refrigerant leak, the LCD
screen will display “EC” and the LED indicator
light will flash.
Preparation For Periods Of Non-Use
Maintenance after Extended Non-Use

its original position.
3. Turn on the main power switch at least 12
hours prior to operating the unit.
Storing the Unit While Not In Use
1. Run the appliance on FAN mode for 12 hours
in a warm room to dry it and prevent mold.

vertically and simplifies the filter cleaning process.
4. Remove the air filter.
5. Clean the air filter by vacuuming the surface
or washing it in warm water with mild
detergent.
A. If using a vacuum cleaner, the inlet side
