3. Clean the Air Filters.
Remove the dust from the Air Filters by
vacuum cleaner or washing them. After
washing, allow the Air Filters to dry
thoroughly in an area protected from sunlight.
5. Push in both sides and the center of the
Intake Grill.
Dust can be cleaned from the Air Filter
either with a vacuum cleaner, or by washing
the filter in a solution of mild detergent and
warm water. If you wash the filter, be sure
to allow it to dry thoroughly in a shady
place before reinstalling.
If dirt is allowed to accumulate on the Air
Filter, air flow will be reduced, lowering
operating efficiency and increasing noise.
During periods of normal use, the Air
Filters should be cleaned every two weeks.

Page 21
CLEANING AND CARE
CAUTION!
The following four procedures are for series 24,28,36,42.
1. Press the two buttons on the filters, until you hear a sound of click.
2. Pull the filters upward to remove them from the Intake Grill.
Before cleaning the air conditioner ,be sure to turn it off and disconnect
the Power Supply Cord.
Be sure the Intake Grill is installed securely.
When removing and replacing the air filters, be sure not to touch the heat
exchanger, as personal injury may result.
3. Clean the air filter: Remove the dust from the filters by vacuum cleaner or washing them. After
washing, allow the air filters to dry thoroughly in an area protected from sunlight.
4. Re-attach the air filters to the Intake Grill, press the two buttons on the filters, until you hear
a sound of click.
When used for extended periods, the unit may accumulate dirt inside, which reduces its
performance. We recommend that the unit is inspected regularly, in addition to your own
cleaning and care. For more information, consult authorized service personnel.
When cleaning the unit's body, do not use water hotter than 40çC, harsh abrasive
cleansers, or volatile agents like benzene or thinner.
Do not expose the unit body to liquid insecticides or hairsprays.
When shutting down the unit for one month or more, first allow the Fan mode to operate
continuously for about half a day to allow internal parts to dry thoroughly.

Page 22
TROUBLE SHOOTING
Followings are not problems
Sound of water flowing is
not a problem.
Sound of cracking is heard.
Smell are generated.
During operation, white fog or steam
comes out from the indoor unit.
In cooling operation, unit switches to
blowing operation.
Unit will not restart after stop.
Won't start?
During unit operation or at stop, a swishing or
gurgling noise may be heard. This noise is generated
by refrigerant flowing in the system.
During unit operation, a cracking noise may be heard.
This noise is generated by the casing expanding or
shrinking because of temperature changes.
This is because the system circulates smells from the
interior air such as the smell of cigarettes or the
painting on the furniture.
When unit is running at places like restaurant, etc. where
dense edible oil fumes always exist, this will happen.
To prevent frost from accumulating on indoor heat
exchanger, unit will switch to blowing operation for a
while then resume cooling operation.
Though ON/OFF button is set
to ON, unit won't resume cooling,
dry or heating operation
in 3 min after it is stopped, this
is because of 3-min-delay
protection circuit.
Please wait 3 minutes
No outlet air or fan speed can't be changed
in dry mode.
In heating operation, water or steam are
blown out of outdoor unit.
In heating operation, indoor fan won't stop
even if unit is stopped.
Unit will reduce fan speed repeatedly and automatically
if room temp. is too low in dry operation.
This occurs when frost accumulated
on the outdoor unit is removed.
(during defrosting operation)
After unit stop, indoor fan will go on running
until indoor unit cools down.
