Safety Precautions
Use power cables of sufficient current
carrying capacity and rating.
• Cables that are too small may leak, generate
heat, and cause a fire.
Do not use the product for special purposes,
such as preserving foods, works of art, etc. It
is a consumer air conditioner, not a precision
refrigeration system.
• There is risk of damage or loss of property.
Keep the unit away from children. The heat
exchanger is very sharp.
• It can cause the injury, such as cutting the finger.
Also the damaged fin may result in degradation
of capacity.
When installting the unit in a hospital, communication station, or similar place, provide
sufficient protection against noise.
•
The inverter equipment, private power generator,
high-frequency medical equipment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the
other hand, the air conditioner may affect such
equipment by creating noise that disturbs medical
treatment or image broadcasting.
Do not install the product where it is exposed to sea wind (salt spray) directly.
• It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins,
could cause product malfunction or inefficient operation.

Safety Precautions
■ Operation
Do not use the air conditioner in special
environments.
• Oil, steam, sulfuric smoke, etc. can significantly
reduce the performance of the air conditioner or
damage its parts.
Do not block the inlet or outlet.
• It may cause failure of appliance or accident.
Make the connections securely so that the
outside force of the cable may not be applied
to the terminals.
• Inadequate connection and fastening may generate heat and cause a fire.
Be sure the installation area does not deteriorate with age.
• If the base collapses, the air conditioner could
fall with it, causing property damage, product
failure, or personal injury.
Install and insulate the drain hose to ensure that water is drained away properly based on the
installation manual.
• A bad connection may cause water leakage.
Be very careful about product transportation.
• Only one person should not carry the product if it weighs more
than 20 kg.
• Some products use PP bands for packaging. Do not use any PP
bands for a means of transportation. It is dangerous.
• Do not touch the heat exchanger fins. Doing so may cut your fingers.
• When transporting the outdoor unit, suspending it at the specified
positions on the unit base. Also support the outdoor unit at four

Safety Precautions
Safely dispose of the packing materials.
•
Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
•
Tear apart and throw away plastic packaging bags
so that children may not play with them. If children
play with a plastic bag which was
not torn apart, they face the
risk of suffocation.
Turn on the power at least 6 hours before
starting operation.
• Starting operation immediately after turning on
the main power switch can result in severe
damage to internal parts. Keep the power switch
turned on during the operational season.
Do not touch any of the refrigerant piping
during and after operation.
• It can cause a burn or frostbite.
Do not operate the air conditioner with the
panels or guards removed.
• Rotating, hot, or high-voltage parts can cause
injuries.
Do not directly turn off the main power
switch after stopping operation.
• Wait at least 5 minutes before turning off the
main power switch. Otherwise it may result in
water leakage or other
problems.
Auto-addressing should be done in condition of
connecting the power of all indoor and outdoour
units. Auto-addressing should also be done in
case of changing the indoor unit PCB.
Use a firm stool or ladder when cleaning or
maintaining the air conditioner.
• Be careful and avoid personal injury.
Do not insert hands or other objects through
the air inlet or outlet while the air conditioner
is plugged in.

Environment-friendly Alternative Refrigerant R410A
Select the Best Location
Select space for installing outdoor unit, which will meet the following conditions:
• No direct thermal radiation from other heat sources
• No possibility of annoying the neighbors by noise from unit
• No exposition to strong wind
• With strength which bears weight of unit
• Note that drain flows out of unit when heating
• With space for air passage and service work shown next
• Because of the possibility of fire, do not install unit to the space where generation, inflow, stagnation, and leak
of combustible gas is expected.
• Avoid unit installation in a place where acidic solution and spray (sulfur) are often used.
• Do not use unit under any special environment where oil, steam and sulfuric gas exist.
• It is recommended to fence round the outdoor unit in order to prevent any person or animal from accessing the
outdoor unit.
• If installation site is area of heavy snowfall, then the following directions should be observed.
- Make the foundation as high as possible.
- Fit a snow protection hood.
• Select installation location considering following conditions to avoid bad condition when additionally performing
defrost operation.
1. Install the outdoor unit at a place well ventilated and having a lot of sunshine in case of installing the prod-
uct at a place with a high humidity in winter (neare beach, coast, lake, etc).
(Ex) Rooftop where sunshine always shines.
2. Performance of heating will be reduced and preheat time of the indoor unit may be lengthened in case of
installing the outdoor unit in winter at following location:
(1) Shade position with a narrow space
(2) Location with much moisture in neighboring floor.
(3) Location with much humidity around.
(4) Location where ventilation is good.
It is recommended to install the outdoor unit at a place with a lot of sunshine as possible as.
(5) Location where water gathers since the floor is not even.
• The refrigerant R410A has the property of higher operating pressure in comparison with R22.
Therefore, all materials have the characteristics of higher resisting pressure than R22 ones and this characteristic should be also considered during the installation.
R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone depletion potential (ODP) of R410A is
0. These days the developed countries have approved it as the environmental-friendly refrigerant and encouraged to use it widely to prevent environmental pollution.
Environment-friendly Alternative Refrigerant R410A
CAUTION:
• The wall thickness of the piping should comply with the relevant local and national regulations for the designed
pressure 3.8MPa
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state.
If the refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.
• Do not place the refrigerant container under the direct rays of the sun to prevent it from exploding.
• For high-pressure refrigerant, any unapproved pipe must not be used.
• Do not heat up pipes more than its necessity to prevent them from softening.
• Be careful not to install wrongly to minimize economic loss because it is expensive in comparison with R22.

locally.
■ Measure the distance between the indoor and the outdoor unit.
■ Cut the pipes a little longer than measured distance.
■ Cut the cable 1.5m longer than the pipe length.
2) Burrs removal
■ Completely remove all burrs from the cut cross section
of pipe/tube.
■ Put the end of the copper tube/pipe to downward direction as you remove burrs in order to avoid to let burrs
drop in the tubing.
3) Flaring work
■ Carry out flaring work using flaring tool as shown below.
Firmly hold copper tube in a bar(or die) as indicated
dimension in the table above.
4) Check
■ Compare the flared work with figure below.
■ If flare is noted to be defective, cut off the flared section
and do flaring work again.
Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

Installation
1. Remove the cap and turn the valve counter clockwise with the hexagon wrench.
2. Turn it until the shaft stops.
Do not apply excessive force to the shutoff valve. Doing so may break the valve body, as the valve is not a
backseat type. Always use the special tool.
3. Make sure to tighten the cap securely.
1. Remove the cap and turn the valve clockwise with the hexagon wrench.
2. Securely tighten the valve until the shaft contacts the main body seal.
3. Make sure to tighten the cap securely.
* For the tightening torque, refer to the table on the below.
Precautions when connecting pipes
• See the following table for flare part machining dimensions.
• When connecting the flare nuts, apply refrigerant oil to the inside and outside of the flares and turn them three
or four times at first. (Use ester oil or ether oil.)
• See the following table for tightening torque.(Applying too much torque may cause the flares to crack.)
• After all the piping has been connected, use nitrogen to perform a gas leak check.

CAUTION
• Always use a charge hose for service port connection.
• After tightening the cap, check that no refrigerant leaks are
present.
• When loosening a flare nut, always use two wrenches in
combination, When connecting the piping, always use a spanner
and torque wrench in combination to tighten the flare nut.
• When connecting a flare nut, coat the flare(inner and outer faces)
with oil for R410A(PVE) and hand tighten the nut 3 to 4 turns as
the initial tightening.
