Read the following " PRECAUTIONS" carefully before installation.
The caution items stated here must be followed because these important contents are related
to safety. The meaning of each indication used is as below.
Incorrect installation due to ignoring of the instruction will cause harm or damage, and the
seriousness is classified by the following indications.
!This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to
properties only.
WARNING
!CAUTION
1. Injury means causing harmed, burned, electrical shocked, but not serious for hospitalization.
2. Damage of property means disrepair of property, material.
Carry out test running to confirm that no abnormality occurs after the installation. Then, expl-
ain to user the operation, care and maintenance as stated in instructions. Please remind the
customer to keep the operating instructions for future reference.
Engage dealer or specialist for installation. If installation done by user is defective, it
will cause water leakage, electrical shock or fire.
Install according to this installation instructions strictly. If installation is defective, it will
cause water leakage, electrical shock or fire.
Use the attached accessories parts and specified parts for installation. Otherwise, it will
cause the set to fall, water leakage, fire or electrical shock.
Install at a strong and firm location which is able to withstand the set's weight. If the stren-
gth is not enough or installation is not properly done, the set will drop and cause injury.
For electrical work, follow the local national wiring standard, regulation and this installa-
tion instructions. An independent circuit and single outlet must be used. If electrical circuit
capacity is not enough or defect found in electrical work, it will cause electrical shock or fire.
When carrying out piping connection, take care not to let air or other substances other
than the specified refrigerant go into refrigeration cycle. Otherwise, it will cause lower
capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.
Grounding is necessary. It may cause electrical shock if grounding is not perfect.
Do not install the unit at place where leakage of flammable gas may occur. In case gas
leaks and accumulates at surrounding of the unit, it may cause fire.

If the air conditioner runs for a long time in
"COOLING" or "DRY" mode at air relative
humidity higher than 80% (doors or windows
opened),dew may generate and drip near air outlet.
The protective device will trip at
following cases.
Stop the appliance and restart it at once
or change other modes during operation,
you have to wait 3 minutes before restarting.
After switching on the power circuit breaker
and then turn on the air conditioner at once,
you have to wait about 20 seconds.
In case all operations have stopped, you need
Press "ON/OFF" button again to restart it.
Set TIMER once again if it has been canceled.
Defrost
After a long time of operation, the air
conditioner should be inspected for
the following items.
Abnormal heating of the power supply
cord and plug or even a burnt smell.
Abnormal operating noise or vibration.
Water leakage from indoor unit.
Metal cabinet electrified .
Stop using the air conditioner if above
problem happened.
It is advisable that the air conditioner
should be given a detail check-up
after using for five years even if none
of the above happen.
Do not place any obstacles in front
of the outlet of the outdoor unit for
fear it affects operation and increases
the noise level.
2-5 minutes are necessary to preheat the indoor heat exchanger at the beginning of
"HEATING" operation, lest cold air be discharged.
In "HEATING" operation the appliance will defrost automatically. This procedure lasts
2 10 minutes, then returns to "HEATING" mode automatically. During defrosting, indoor
fan stop running and return to heating mode operation automatically when
defrosting has finished.
Inspection
Noise pollutionOperating condition
The protective device maybe trip and stop
the unit within temp range listed below:
HEATING
Outdoor air temperature is over 24
COOLING
Outdoor air temperature is below -7
Room temperature is over 31
Outdoor air temperature is over 43
Room temperature is below -15
Install the air conditioner in a place
that can bear its weight in order to
operate more quietly.
Install the outdoor unit in a place
where the air discharged and the
operation noise do not annoy your
neighbors.

Please adjust roomtemperature properly especiallywhen the old men, children, patients
stay at house.
Lightning and otherelectromagnetic radiation maycause ill effect .If it is ,please plug
off the powerswitch ,and replugin ,then restart the unit.
Do not blockthe inlet of indoor unit or outlet of oudoor unit, any of blocks will reduce
cooling or heatingefficiency.

Select installation location considering piping and wiring connection after the Indoor Unit has
been hanged. Then decide the piping wiring leading direction.
Be sure to lead the refrigerant pipes, drain pipes and connection wires out to its connection
location before hanging the unit if the opening on the ceiling has been decided.
Confirm sizes of the indoor unit and ceiling opening with the attached installation paper
pattern. (Please fix the paper pattern below the body with M5X16 screws (4).

The drain pipe of indoor unit must have the heat insulation , or it will condense dew, as well as the
connections of the indoor unit.
The declivity of the drain pipe downwards should be over 2/100, and no winding and bending.
The total length of the drain pipe when pulled out traversely shall not exceed 20m , when the
pipe is over long, a prop stand must be installed every 1.5 to 2m to prevent winding.
Refer to the following figures about the installation of the pipes.
Do not impose any pressure on the connection part of the drainage pipe.
PANEL INSTALLATION (SOLD SEPARATELY)
Panel installation should be done after piping and wiring.
Be sure that the indoor unit and ceiling hole installation size is right before installation.
Be sure to seal the connection parts between - and the panel - the
indoor unit ,or even small gaps may cause wind/water leakage or condensing water.
