DANGER
Never put hands or objects into the Air Outlet of indoor or outdoor
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.

ralize the room temperature evenly. Thus you can enjoy it more comfortably.
1. Set the desired air flow direction.
Push the SWING button to adjust the louver to the desired position and push this button again to
maintain the louver at this position.
2. Adjust the air flow direction automatically.
Push the SWING button, the louver will swing automatically.
While this function is set, the swing fan of indoor unit runs; otherwise, the swing fan doesn't run. The
0
swing scale of every side is 30 . When the air conditioner isn't in operation (including when "TIMER
ON" is set), the SWING button will be disabled.
The following is how to adjust air flow direction when air outlet part (separately saled) is
used with the indoor unit.

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.
2. Take out the air-in grill (together with the air filter shown in Sketch B)
o
Pull the air-in grill down at 45 and lift it up to take out the grill.
3. Dismantle the air filter
4. Clean the air filter(Vacuum cleaner or pure water may be used to clean the air filter. If the dust
accumulation is too heavy , please use soft brush and mild detergent to clean it and dry out in cool
place) .
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).

Dry operation
Heating operating
(cooling only type without)
Location:
Be careful of noise or vibrations
Wire
During cooling operation, the air conditioner will dry the room air, so please fix a pipe to drain all the
water away from the air conditioner.
Please let the indoor unit more than one metre away from the TV set and the radio in order to avoid
the picture and noise interference.
Powerful radio transmitters or any other devices radiating high frequency radio waves can cause
the air conditioner to malfunction. Please consult the dealer where you purchased the air conditio-
ner before installing it.
Don't fix the unit in the dangerous region with combustible gas or volatile matter.
If the air conditioner operates in an atmosphere containing oils (machine oil), salt (near a coastal
area), sulfide gas (near a hot spring), etc., such substances may lead to failure of the air conditioner.
Please fix the unit in the stable place to avoid the noise or vibrations.
The noise near the air outlet of the outdoor unit may enter the air exit.
Locate the outdoor unit where noise emitted by it or hot air from its air outlet will cause no nuisance
to your neighbours.
If the air conditioner sounds abnormal during operation, contact the dealer where you purchased the
air conditioner.
To avoid the electric shock, please link the air conditioner with the ground. The plug in the air
conditioner has joined the ground wiring, please don't change it freely.
The power socket is used as the air conditioner specially.
Don't pull the power wiring hard.
When linking the air conditioner with the ground, observe the local rulers.
If necessary, use the power fuse or the circuit, breaker or the corresponding scale ampere.
If you want to change the power wiring, please contact the centre service of the local MD electric
appliance.
