as follows:
Press any button when flashes, Heat Pump is set.
Press any button when flashes, Cooling Only is set.
If you don't press any button within 12 seconds, the remote controller is preset as Heat Pump automatically.
Note:
If the air conditioner you purchased is a Cooling Only one, but you preset the remote controller as Heat Pump, it doesn't
bring any matter. But if the air conditioner you purchased is a Heat Pump one, and you preset the remote controller as
Cooling Only, then you CAN NOT preset the Heating operation with the remote controller.
Back-light function (optional)
Hold down any button of remote controller for about 2 seconds, back-light turns on. Release the button,
it lights off automatically 10 seconds later.
Note: Back-light is an optional function.

Safety precautions
Symbols in this Use and Care Manual are interpreted as shown below.
Be sure not to do.
The feature of the appliance,
instead of a fault.
Pay attention to such a situation.
Use correct power supply in
accordance with the rating plate
requirement. Otherwise, serious
faults or hazard may occur or a
fire maybe break out.
Keep the power supply circuit breaker
or plug from dirt. Connect the power
supply cord to it firmly and correctly,
lest an electric shock or a fire break out
due to insufficient contact.
ON

Be sure to follow this instruction.
Grounding is essential.
Warning: Incorrect handling could
cause a serious hazard, such as death,
serious injury, etc.
ON
OFF
Do not use the power supply circuit
breaker or pull off the plug to turn it off
during operation. This may cause a fire
due to spark, etc.
Do not knit, pull or press the power supply
cord, lest the power supply cord be broken.
An electric shock or fire is probably caused
by a broken power supply cord.

Turn off the appliance by remote control
firstly before cutting off power supply if
malfunction occurs.
Do not touch the operation buttons
when your hands are wet.
Never insert a stick or similar obstacle
to the unit. Since the fan rotates at high
speed, this may cause an injury.
Do not repair the appliance by yourself.
If this is done incorrectly, it may cause an
electric shock, etc.
Do not put any objects on the outdoor
unit.
2
It is harmful to your health if the cool air
reaches you for a long time. It is advisable
to let the air flow be deflected to all the room.
Prevent the air flow from reaching the gas
burners and stove.
It is the user's responsibility to make the
appliance be grounded according to
local codes or ordinances by a licenced
technician.

Reattach the cover by sliding it back into position.
Note:
Use 2 LR03 AA(1.5volt) batteries. Do not use rechargeable batteries.
Replace batteries with new ones of the same type when the display
becomes dim.
If the replacement is done within 1 minute, the remote controller
will keep original presetting. However, if you want to change the
presetting from Heat Pump to Cool Only or Cool Only to Heat Pump,
you should reload batteries 3 minutes after removing the old ones.
(Please refer to page 1 for details.)

air outlet of the outdoor unit lest it increases
the noise level.
Restarting the unit at once after operation stops or changing mode during operation, you need to
wait 3 minutes.
Connect to power supply and turn on the unit at once, it may start 20 seconds later.
If all operation has stopped, press ON/OFFbutton again to restart, Timer should be set again

This odor may come from another source
such as furniture, cigarette etc, which is

The sound may be generated by the expansion
or contraction of the front panel due to change
of temperature.
Mist appears when the room air becomes
very cold because of cool air discharged
from indoor unit during COOLING or DRY

connection.
Note: For some models, it is necessary to remove the cabinet to
connect to indoor unit terminal.

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.

it in case of need. If not possible, connect appliance to a double-pole switching device with contact
separation of at least 3 mm placed in an accessible position even after installation.

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 not to disturb your neighbor and 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.
2. Install and Fix Outdoor Unit
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.
Note: To protect the environment, be sure not to discharge the refrigerant to the air directly.
See next page for air purging steps.

Installation instructions
How to Purge Air Tubes:
(1). Unscrew and remove caps from 2 and 3-way valves.
(2). Unscrew and remove cap from service valve.
(3). Connect vacuum pump flexible hose to the service valve.
(4). Start vacuum pump for 10-15 minutes until reaching a vacuum of 10 mm Hg absolutes.
(5). With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop
vacuum pump.
(6). Open 2-way valve 1/4 turn then close it after 10 seconds. Check tightness of all joints using liquid
soap or an electronic leak detector.
(7). Turn 2 and 3-way valves stem to fully the valves. Disconnect vacuum pump flexible hose.
(8). Replace and tighten all valve caps.
Notes
Please read this manual before installing and using it.
Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner.
Testing run the air conditioner after finishing installation, and record details of operation.
Type of fuse used on indoor unit controller is 50T, with rating 2.5A,AC250V.
The fuse for the whole unit is to be provided by the user according to the current at maximum power
Input or use other over-current protective device instead.
Only the air conditioner can be connected to the power line.
The power connection for the air conditioner has to be done at the main power distribution which has
to be of a low impedance.
In order to ensure the suitability of the equipment for connection, the user should consult with the
supply authority, if necessary, that the service current capacity at the interface point is sufficient
for the equipment.
Refer to the rating plate of the equipment for power consumption details.
If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or
similarly qualified person in order to avoid a hazard.
