SAFETY PRECAUTIONS
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.
WARNING
This symbol indicates the possibility of death or serious injury.
CAUTION
This symbol indicates the possibility of injury or damage to property.
The items to be followed are classified by the symbols:
Symbol with background white denotes item that is PROHIBITED from doing.
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.

INSTALLATION INSTRUCTIONS
Selecting installation place
Select an installation location which is rigid and strong enough to support or hold the unit, and select a
location for easy maintenance. Read completely, then follow step by step.
Indoor unit
Do not expose the indoor unit to heat or steam.
Select a place where there are no obstacles in front
or around the unit.

will fade the plastic cabinet and affect its appearance. If
unavoidable, sunlight prevention should be taken into considenation.
Outdoor unit
If an awning is built over the outdoor unit to prevent
direct sunlight or rain exposure, make sure that heat
radiation from the condenser is not restricted.
Keep the spaces indicated by arrows from wall or
other obstacles.
Do not place animals and plants in the path of the
air inlet or outlet.
Take the air conditioner weight into account and
select a place where noise, vibration and hot air
discharged will not be an issue.
Do not install in a place full of machine oil or sulfide
gas such as hot-spring resort.
Do not install in a saline place such as coast.
Do not install in a place where there are high frequency
machines such as wireless equipment, welding
machine or medical facility.

Outdoor unit installation
Outdoor installation precaution
Strong
wind
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.

Oblique Roughness
1. Flaring work
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(59 In) longer than the pipe
length.

AIR PURGING
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for
the method of wiring, be guided by the circuit diagram posted on the inside of control
cover.
2) The screw which fasten the wiring in the casing of electrical fittings are liable to come
loose from vibrations to which the unit is subjected during the course of
transportation. Check them and make sure that they are all tightly fastened. (If they
are loose, it could cause burn-out of the wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the rated
voltage marked on the name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
7) Always install an earth leakage circuit breaker in a wet or moist area.
8) The following would be caused by voltage drop.
Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the
normal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the fixed
wiring and have an air gap contact separation of at least 3mm in each active(phase)
conductors.
Air purging
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.
Air purging with vacuum pump
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.

TEST RUNNING
Safety and leakage check
● Electrical safety check
Perform the electric safe check after completing installation:
1. Grounding work
After finishing grounding work, measure the grounding resistance by visual detection and
grounding resistance tester. Make sure the grounding resistance is less than 4 Ω.
2. Electrical leakage check (performing during test running)
During test operation after finishing installation, the serviceman can use the electroprobe
and multimeter to perform the electrical leakage check. Turn off the unit immediately if
leakage happens. Check and find out the solution ways till the unit operate properly.
● Gas leak check
1. Soap water method:
Apply a soap water or a liquid neutral detergent
on the indoor unit connection or outdoor unit
connections by a soft brush to check for leakage
of the connecting points of th piping. If bubbles
come out, the pipes have leakage.
2. Leak detector
Use the leak detector to check for leakage.
