substitute a blown fuse with a
fusethat has a higher or lower amperage
rating,as this may damage the circuit or
cause anelectrical re.
•
Make sure the drain hose is set up according
to the instructions. Failure to do so could
cause leakage and result in personal
property damage, re and electric shock.

How To Clean The Air Filter
The lter prevents dust and other particles from
entering the indoor unit. Dust buildup can reduce
the efciency of the air conditioner. For optimum
efciency, clean the air lter every two weeks or
more frequently if you live in a dusty area. Replace
the lter with a new one if it’s heavily clogged and
cannot be cleaned.
WARNING: DO NOT REMOVE OR

Removing and cleaning the lter can be
dangerous. Removal and maintenance must
be performed by a certied technician.
NOTE: In households with animals, you will
have toperiodically wipe down the grille to

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 ammable.
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
• In the event of a refrigerant leak, the LCD
screen will display “EC” and the LED
indicator light will ash.
Preparation For Periods Of Non-Use
Maintenance after Extended Non-Use
