units. These units are installed with a fan running at high speed.
To touch the moving fan will cause serious injury.
Do not use liquid cleaners or aerosol cleaners, use a soft and dry
cloth for cleaning the unit. To avoid electric shock, never attempt
to clean the units by sprinkling water.
For proper performance, operate the unit in temperature and
humidity ranges indicated in this owner's manual. If the unit is
operated beyond these conditions, it may cause malfunctions
of the unit or dew dripping from the unit.

HINTS FOR ECONOMICAL OPERATION
The following should be noticed to ensure an economical operation. (Refer to corresponding chapter
for details)
Adjust the air flow direction properly to avoid winding toward your body.
Adjust the room temperature properly to get a comfortable situation and to avoid supercooling and
superheat.
In cooling, close the curtains to avoid direct sunlight.
To keep cool or warm air in the room, never open doors or windows more often than necessary.
Set the timer for the desired operating time.
Never put obstructions near the air outlet or the air inlet. Or it will cause lower efficiency, even a
sudden stop.
If you don't plan to use the unit for a long time, please disconnect power and remove the batteries
from the remote controller. When the power switch is connected, some energy will be consumed,
even if the air conditioner isn't in operation. So please disconnect the power to save energy. And
please switch the power on 12 hours before you restart the unit to ensure a smooth operation.
A clogged air filter will reduce cooling or heating efficiency, please clean it once two weeks.

WARNING
Cleaning the indoor unit and remote controller
WARNING
Before you clean the air conditioner, be sure to disconnect the power supply plug.
If you do not plan to use the unit for at least 1 month.
(1) Operate the fan for about half a day to dry the inside of the unit.
(2) Stop the air conditioner and disconnect power.
(3) Remove the batteries from the remote controller.
!
Use a dry cloth to wipe the indoor unit and remote controller.
A cloth dampened with cold water may be used on the indoor unit if it is very dirty.
Never use a damp cloth on the remote controller.
Do not use a chemically-treted duster for wiping or leave such material on the unit for long,
because it may damage or fade the surface of the unit.
Do not use benzine, thinner, polishing powder, or similar solvents for cleaning. These may
cause the plastic surface to crack or deform.
CAUTIONS

Checks before operation
Cleaning the air filter
Check that the wiring is not broken off or disconnected.
Check that the air filter is installed. (Some air-conditioners haven't air filters.)
Check that the outdoor unit air outlet or inlet is not blocked.
Before you clean the air conditioner, be sure to disconnect the power supply plug.
The air filter can prevent the dust or other particulate from going inside .In case of blockage of the filter , the
working efficiency of the air conditioner may greatly decrease .Therefore , the filter must be cleaned once two
weeks during long time usage.
If the air conditioner is positioned in a dust place , the cleaning frequency of the air filter must be increased .
If the accumulated dust is too heavy to be cleaned , please replace the filter with a new one(replaceable air
filter is an optional fitting).
