the air discharged and the operation noise
would not annoy your neighbors.
Do not place any obstacles in front of the
air outlet of the outdoor unit as it will increase
the noise level and possible malfunction
of fan motor.
* For Tropical (T3) Climate condition models, the
temperature point is 96 f instead of 96 f.
If the air conditioner runs in COOLING or DRY mode with
door or window opened for a long time when relative
humidity is above 80%,dew may drip down from the outlet.
Features of protector
The protective device will work as follows.

minutes later.
Afterheat
After the finishing of HEATING operation, the airflow from indoor unit is discharged 2-5
minutes.
Defrost
In HEATING operation the appliance will defrost (de-ice) automatically to raise efficiency.
This procedure usually lasts 2-10 minutes. During defrosting, fans stop operation.
After defrosting completes, it returns to HEATING mode automatically.
Note: Heating is NOT available for cooling only air conditioner models.

1Troubleshooting
The following cases may not always be a malfunction, please check it before asking for service.
Analysis
If the plug is not properly plugged.
If batteries in the remote controller exhausted.
If the protective device works to protect the appliance.
Trouble
Does not run
If the protector trip or fuse is blown.
Are the intakes and outlets of the air conditioner
blocked
Is the temperature set properly
No cooling or
heating air
Is the air filter dirty?
If strong interference(from excessive static electricity
discharge, power supply voltage abnormality)presents,
operation will be abnormal. At this time, disconnect
from the power supply and connect back 2-3 seconds later.
Ineffective control
Does not operate
immediately
Changing mode during operation, 3 minutes
will delay.
don't run
This odor may come from another source
such as furniture, cigarette etc, which is
sucked in the unit and blows out with the air.
Peculiar odor
A sound of
flowing water
Caused by the flow of refrigerant in the
air conditioner, not a problem.
Defrosting sound in heating mode.
Cracking sound is
heard
The sound may be generated by the expansion
or contraction of the front panel due to change
of temperature.
Spray mist from
the outlet
Mist appears when the room air becomes
very cold because of cool air discharged
from indoor unit during COOLING or DRY
operation mode.
The compressor indicator(red) lights on
constantly,and indoor fan stops.
The unit is shifting from heating mode to defrost.
The indicator will lights go off within ten minutes
and returns to heating mode.
Air will not
immediately
blow out at the start of HEAT mode
The air conditioner is ready to blow out enough warm
air please wait(2~5 minutes )
Stop
discharging
airflow for 5~10minutes
during HEATING operation
The appliance will defrost automatically ,and mist
appears from outdoor.After defrosting ,it continues to
run automatically.
The remote
control
does not function correctly

Connecting the refrigerant lines between the indoor& outdoor units
Note that since the refrigerant metering device is located in the outdoor unit,both refrigerant
lines must be insulated with a minimum of 3/8 " foam along the entire length.
Gently bend the line set stubs from the indoor unit to the desired location and the using 2 box
end or adjustable wrenches,remove the flare nuts from the indoor unit line stubs.The indoor
unit is charged with a dry gas.If you do not hear the release of pressure when removing the
flare nuts,it is possible that the evaporator section(indoor unit)has developed a leak and you
should contact your dealer for a replacement indoor unit.Note:Using a small amount of
vacuum pump oil on the male flare threads will ease installation.Snug the line set to the stubs
using the 2 wrenches-one wrench on the male fitting and one wrench on the female fitting.

1). Remove the access door from the unit by loosening
the screw. Connect the wires to the terminals on the
control board individually as the following.
2). Secure the power connecting cord onto the control
board with cable clamp.
3). Reinstall the access door to the original position
with the screw.
4) Use a recognized circuit breaker for 24K.30K model
between the power source and the unit. A disconnecting
device to adequately disconnect all supply lines must be
fitted.

The figures in this manual are based on the external view of a standard model.
Consequently, the shape may differ from that of the air conditioner you have selected.
Caution:
1. Never fail to have an individual power circuit specifically for the air conditioner. As for the
method of wiring, refer to the circuit diagram posted on the inside of the access door .
2.Comfirm that the cable thickness is as specified in the power source specification.
(See the cable specification table below)
3.Check the wires and make sure that they are all tightly fastened after cable connection.
4. Be sure to install an earth leakage circuit breaker in wet or moist area.

1Installation Instructions
Outdoor Unit Installation
1.Install Drain Port and Drain Hose (for heat-pump model only)
The condensate drains from the outdoor unit when the unit operates
in heating mode. In order to protect the environment, install a drain
port and a drain hose to direct the condensate water. Just install the
drain port and rubber washer to the chassis of the outdoor unit, then
connect a drain hose to the port as the right figure shown.

Drain port
2. Install and Fix Outdoor Unit
Drain hose
(prepare by user)
Fix with bolts and nuts tightly on a flat and strong floor.
If installed on the wall or roof, make sure to fix the supporter well to prevent it
from shaking due to serious vibration or strong wind.
3. Outdoor Unit Piping Connection
Remove the valve caps from the 2-way and 3-way valve.
Connect the pipes to the 2-way and 3-way valves separately according to the required torque.
4. Outdoor Unit Cable Connection (see previous page)
Air Purging
The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the
compressor. After connecting the indoor and outdoor units, evacuate air and moisture from refrigerant
cycle using a vacuum pump, as shown below.
