Note Before Operation
Confirm Before Operation
Make sure that the ground wire is not broken or fallen off.
Make sure the air filter is installed.
Turn on the power switch for 12 hours before the operation.
About Heating Capacity
Heating is that the outdoor unit absorbs the outdoor heat then transmit the heat to the indoor unit.
When the heating pump starts, the outdoor unit blows the cold air and the outdoor temp. fall.
Defrosting during the Heating Operation
Under the heating mode ,when frost generating on the outdoor unit the air conditioner starts
defrosting automatically. (About 2~10minutes)
Indoor/Outdoor fan stops the running during the defrosting.
About 3 Minutes Protection
The outdoor unit would not run within 3 minutes during restarting. This is self-protection of the
unit.

About Power Off
All the operations will stop if there is a power off.
The buzzer of the display will make a sound and the operation indicator will flash when the power is
on after a failure.
Press ON/OFF button to restart the unit.
About Protection Device
when starting the unit compulsorily while the unit does not prepare for the starting, the on/off indicator lights,
the protection device is activated and the unit stops.
When the Protection Device is Activated
Cooling Operation
The air Intake and the air outlet of the outdoor unit are blocked.
Strong wind outside is blowing into the air outlet of the outdoor unit.
Heating Operation
The air filter is too dirty.
The air intake and the air outlet of the indoor unit are blocked.
Fan Runs after the Indoor Unit Stopped
To protect the machine, one of the indoor units, which stops the running while the other indoor units are still
running, will run its fan at low speed for 3 minutes every 1 hour on cooling operation or every 4 hours on heating
operation.
CAUTION
Confirm the air filter is installed. The heat exchanger would accumulate dust or leak water
without the air filter.
One indoor unit can run alone, or run with other indoor units, but can not run under heating
mode while others run under cooling mode.

When the outdoor temp. is low the heating capacity drop, please use the air- conditioner with other
heating equipments or purchase the digital scroll central air-conditioner auxiliary heating device.

CAUTION
Do not disconnect the power.
Connect to the power 12 hours before
starting the unit
One of the indoor units can not run on
the cooling mode while the other indoor
units run on the heating mode.
Place it away from TV or radio.
12 hours before
Put the louver horizontally when
cooling.
Do not disconnect
the power.
Do not disconnect the power when the unit
is in operation. Please control it with the
remote controller.
To protect the compressor, please turn on
the power switch 12 hours before starting
the unit.
Please run every indoor unit on the same mode.
Put the TV or radio away from the air
conditioner at least 1 meter, or signal will
be interfered.
There will be water condensing on the louvers if
setting the louvers down when cooling.

ADJUSTING THE AIR FLOW DIRECTION
Because cold air flow down and hot air flow up, to improve the cooling and heating effect,
please adjust air flow louver direction , in result the temperature of the room will be natural and
equal and you will fell more comfortable.
NOTE : The heating operation with horizontal air out let will increase the difference of the room
temperature.
!
Notice Notice the
louver
direction
Choose horizontal outlet mode when cooling operation
When the cooling operation ,the air flow down will cause condensing
dew on the air outlet and louver surface.
Four-Way Cassette Type
Cooling operation Heating operation
When using the panel with auto.louver, press SWING button , the auto.louver will swing automatically
and the best cooling(heating) effects will be achieved.
Adjust the louver horizontally . Adjust the louver down.

To effectively heat the bottom of the room
please set the louver downwards.
Cooling
To effectively cool the whole room, please
adjust the louver horizontally.

METHOD FOR CLEANING THE AIR FILTER
The air filter can prevent the dust or other particles 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 using.
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(the replaceable air
filter is an optional fitting).
1. Take out the air-in grill
Four- Way Cassette Type
Push the grill switches towards the middle simultaneously as indicated in sketch A. Then pull down the air-in grill. Take
out the air-in grill (together with the air filter shown in Sketch B).Pull the air-in grill down at 45 and lift it up to take out
the grill.
Cautions: The control box cables, which are originally connected with the main body electrical terminators
must be pulled off before doing as indicated above.
CAUTION
MAINTENANCE
Only the specialized maintenance person can perform the maintenance work.
The main power switch must be turned off before doing electrical connection or cleaning the air filter.
Do not use water or air of temperature above 50 to clean the air filter or the panel.

B
A
For Duct/Ceiling Type
Push the grill switches to the arrow directions , then open the air-in grill downwards. Turn back the air filter fixing block,
then take out the air-in grill.
2. Dismantle the air filter.
3. 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 the cool place).
11
Cautions : Do not dry out the air filter under direct sunshine or with fire.
For the one-way cassette type , the air filter should be installed before the unit body installation.
Use a dry and soft cloth to wipe it.
Pure water or mild detergent may be used if it is very dirty.
Do not use benzene, thinner, polishing power, or similar solvents for cleaning. These may cause the surface to
crack or deform.
To avoid the risk of electrical shock or fire, do not let water fall into the indoor unit.
Never wipe the air flow louver violently.
An air conditioner without air filter can not expel the dust out of the room, which would cause malfunctions by
accumulation.
1. Injures may happen by improper operations because of the sharp blade of some plates and the freezer.
2. Check the air outlet and the air inlet of the outdoor unit regularly to ensure that they are not choked by filth or
soot.
3. The coil and other parts of the outdoor unit should also be checked regularly. Please contact with your
local dealer.
MAINTENANCE
CLEANING THE AIR OUTLET AND THE PANEL
CAUTIONS
MAINTENANCE OF THE OUTDOOR UNIT
The air-in side should face up when using vacuum cleaner.
The air-in side should face down when using water.
4. Re-install the air filter.
5. Install and close the air-in grill in the reverse orders of step 1 and 2 and connect the control box cables to the
corresponding terminators of the main body.

Operate the fan for about half a day to dry the inside of the unit.
Turn off the unit with the ON/OFF button on the remote controller,then disconnect the power.
When the power switch is connected, some energy will be consumed, even if the unit is not in operation. So
please disconnect the power to save energy.
A degree of filth will be accumulated due to certain performance after several seasons of operation. So special
maintenance is advised.
Take out of the batteries from the remote controller.
IF YOU DO NOT PLAN TO USE THE UNIT FOR A LONG TIME
NOTE
1. Check before operation
Check the air outlets or inlets of the indoor/ outdoor unit are not blocked.
Check the grounding wire is not broken off and is connected well.
2. Restore the air filter and the front panel
The air filter and the front panel must be fixed to the original position after having been cleaned.
3. Connect the main power switch
To protect the air conditioner, power should be provided 12 hours before operation. Then the OPERATION
lamp on the control box of the indoor unit will flash once a second.
RESTART AFTER A LONG TIME

AIR-CONDITIONER AUXILIARY HEATING EQUIPMENT
In winter, due to the difference of the area and building construction, please purchase the indoor unit with auxiliary heating
to enlarge the heating capacity. When turning to the heat mode the air-conditioner with auxiliary heating will run at the set
,
temp. .It s no need to install auxiliary heating equipments on site for 4-way cassette type and duct/ceiling type (with
auxiliary heating).
