SAFETY PRECAUTIONS
1. Safety precautions

WARNING
Read the follow SAFETY PRECAUTIONS carefully before installation.
Electrical work must be installed by a licensed electrician. Be sure to use the correct rating
of the power plug and main circuit for the model to be installed.
Incorrect installation due to ignoring of the instruction will cause harm or damage.
The seriousness is classified by the following indications.
This symbol indicates the possibility of death or serious injury.
The items to be followed are classified by the symbols:
Symbol with background white denotes item that is PROHIBITED from doing.
CAUTION
This symbol indicates the possibility of injury or damage to property.
WARNING
1) Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water
leakage, electrical shock fire.
2) Install according to this installation instructions strictly. If installation is defective, it will cause water
leakage, electrical shock fire.
3) Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set to fall,
water leakage, electrical shock fire.
4) Install at a strong and firm location which is able to withstand the set s weight. If the strength is not enough
or installation is not properly done, the set will drop and cause injury.
,
5) For electrical work, follow the local national wiring standard, regulation and this installation 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 fire.
6) Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on
the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover
is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.
8) When carrying out piping connection, take care not to let air 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.
9) Do not modify the length of the power supply cord or use of extension cord, and do not share the
single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
CAUTION
1) This equipment must be earthed and installed with earth leakage current breaker. It may cause electrical
shock if grounding is not perfect.
2) 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.
3) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water
may enter the room and damage the furniture.

1)
Fit the installation plate horizontally on structural parts of the wall with spaces
arround the installation plate.
2)
If the wall is made of brick, concrete or like, drill five or eight 5mm diameter holes
in the wall. Insert Clip anchor for appropiates mounting screws.
1. Determine hole positions according to left and right
side of the installation plate. The hole center is obtained
by measuring the distance as shown in the diagram above.
2. Dirll the piping plate hole with φ65mm hole-core drill.
3. Drill the piping hole at either the right or the left and the
hole should be slightly slanted to the outdoor side.
4. Always take steps to protect the pipe when drilling metal
grid, metal plate or the like.

INDOOR AND OUTDOOR UNIT INSTALLATION
Do not block water flow by a rise.
Do not put the end of
drain hose into water.
1. Run the drain hose sloping downward.
Do not install the drain hose as
illustrated in Fig.7.
2. When connecting extension drain hose,
insulate the connecting part of extension
drain hose with a shield pipe, do not let
the drain hose slack.
1. For the left-hand and right-hand piping,
remove the pipe cover from the side
panel.
2. For the rear-right-hand and rear-left-hand
piping, install the piping as shown in Fig.10.
3. Fix the end of the connective pipe. (Refer
to Tightening Connection in REFRIGERANT
PIPING CONNECTION)

Connect the indoor unit first, then the
outdoor unit.
Do not allow the piping to let out from
the back of the indoor unit.
Be careful not to let the drain hose slack.
Heat insulated both of the auxiliary piping.
Be sure that the drain hose is located at
the lowest side of the bundle. Locating
at the upper side can cause drain pan
to overflow inside the unit.
Never intercross nor intertwist the power
wire with any other wiring.
Run the drain hose sloped downward to
drain out the condensed water smoothly.

Caution
3. Outdoor unit installation
Install the outdoor unit on a rigid base to prevent increasing noise level and vibration.
Determine the air outlet direction where the discharged air is not blocked. In the case that
the installation place is exposed to strong wind such as a seaside, make sure the fan operating
properly by putting the unit lengthwise along the wall or using a dust or shield plates.
Specially in windy area, install the unit to prevent the admission of wind. If need suspending
installation, the installation bracket should
accord with technique requirement in the
installation bracket diagram.
The installation wall should be solid brick, concrete or the same intensity construction, or
actions to reinforce, damping supporting should be taken. The connection between bracket and
wall, bracket and the air conditioner should be firm, stable and reliable.
Be sure there is no obstacle which block radiating air.

Main cause for refrigerant leakage
is due to defect in the flaring work.
Carry out correct flaring work
using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory or pipes
purchased locally.
2. Measure the distance between the indoor
and the outdoor unit.
3. Cut the pipes a little longer than the
measured distance.
4. Cut the cable 1.5m longer than the pipe
length.

2. Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.

Air and moisture in the refrigerant system have undesirable effects as indicated below:
● Pressure in the system rises.
● Operating current rises.
● Cooling or heating efficiency drops.
● Moisture in the refrigerant circuit may freeze and block capillary tubing.
● Water may lead to corrosion of parts in the refrigeration system.
Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested
and evacuated to remove any noncondensables and moisture from the system.
●Preparation
Check that each tube(both liquid and gas side tubes) between the indoor and outdoor units
have been properly connected and all wiring for the test run has been completed. Remove
the service valve caps from both the gas and the liquid side on the outdoor unit. Note that
both the liquid and the gas side service valves on the outdoor unit are kept closed at this
stage.
●Pipe length and refrigerant amount:
When relocate the unit to another place,
perform evacuation using vacuum pump.
Make sure the refrigerant added into the air
conditioner is liquid form in any case.

Measure the voltage supply and make sure it is within the specified range.
Testing must be performed in all modes of operation.
To operate in cool mode, press the ON/OFF button of the remote controller to place the unit in
-
- cooling mode and select a temperature below room temperature.
To operate in heat mode, press the ON/OFF button of the remote controller to place the unit in
- heating mode and select a temperature above room temperature.
You can also check the manual button. This is used when you do not have the remote controller and
- and is located under the front panel.

8. Function of automatic wiring/piping correction
Automatic Wiring/Piping Correction Function:
More recent models now feature automatic correction of wiring/piping errors. Press the "check
switch" on the outdoor unit PCB board for 5 seconds until the LED displays "CE”, indicating that this
function is working, Approximately 5-10 minutes after the switch is pressed, the "CE" disappears,
meaning that the wiring/piping error is corrected and all wiring/piping is properly connected.
How To Activate This Function:
1. Check that outside temperature is above 5℃.
(This function does not work when outside temperature is not above 5℃)
2. Check that the stop valves of the liquid pipe and gas pipe are open.
3. Turn on the breaker and wait at least 2 minutes.
4. Press the check switch on the outdoor PCB board unit LED display "CE".
