WARNING
For installation purposes, be sure to use the parts supplied by the manufacturer or
other prescribed parts.
Using non-specifi ed parts will cause serious accidents such as falling unit, refriger-
ant leakage, water leakage, electric shock, and fi re.
performed, might lead to the death or serious injury of the
user.
.
To in st all a u nit th at us es the R410A refrigerant, use dedicated tools and piping
materials that have been manufactured specifi cally for R410A use.
Because the pressure of the R410A refrigerant is approximately 1.6 times higher
than the R22, failure to use dedicated piping material or improper installation can
cause rupture or injury.
It will also cause serious accidents such as refrigerant leakage, water leakage,
electric shock, and fi re.
Do not use this equipment with air or any other unspecifi ed refrigerant in the refrig-
erant lines.
Excess pressure can cause a rupture.
Be sure to install the unit as prescribed, so that it can withstand earthquakes and
typhoons or other strong winds.
Improper installation can cause the unit to topple or fall, or other accidents
Ensure that the outdoor unit is securely installed at a place that can withstand the
weight of the unit.
Improper installation will cause injuries caused by falling unit.
If there is a refrigerant leakage, make sure that it does not exceed the concentration limit.
If a refrigerant leakage exceeds the concentration limit, it can lead to accidents
such as oxygen starvation.
If a refrigerant leakage occurs during operation, immediately vacate the premises
and thoroughly ventilate the area.
If the refrigerant is exposed to fi re, it will create a hazardous gas.
Electrical work must be performed in accordance with this Installation manual by a
person certifi ed under the national or regional regulations. Be sure to use a dedi-
cated circuit for the unit.
An insuffi cient power supply circuit or improperly performed electrical work can
cause serious accidents such as electric shock or fi re.
For wiring, use the prescribed type of cables, connect them securely, making sure
that there are no external forces of the cables applied to the terminal connections.
Improperly connected or secured cables can cause serious accidents such as
overheating the terminals, electric shock, or fi re.
Do not turn ON the power until all work has been completed.
Turning ON the power before the work is completed can cause serious accidents
such as electric shock or fi re.
After the installation, make sure there is no refrigerant leakage.
If the refrigerant leaks into the room and becomes exposed to a source of fi re such
as a fan heater, stove, or burner, it will create a hazardous gas.
Use a wall hole pipe. Otherwise, it may cause a short circuit.
Do not place the outdoor unit near the handrail of the balcony.
Children may climb onto the outdoor unit, lean over the handrail and fall over.
Use only a specifi ed power cable. Poor connection, poor insulation, and exceeding the
allowable current will lead to electric shock and fi re
Attach the connecting cables securely to the terminal. Or secure it fi rmly with a "wir-
ing suppressor".
Loose connection will lead to malfunction, electric shock, and fi re.
Install a breaker to cut off all AC main current at the same time.
If you do not install a breaker, it may cause electric shock and fi re.
During installation, make sure that the refrigerant pipe is attached fi rmly before you
run the compressor.
Do not operate the compressor under the condition of refrigerant piping not
attached properly with 2-way or 3-way valve open. This may cause abnormal pressure in the refrigeration cycle that leads to rupture and even injury.
During the pump-down operation, make sure that the compressor is turned off
before you remove the refrigerant piping. Do not remove the connection pipe while
the compressor is in operation with 2-way or 3-way valve open. This may cause
abnormal pressure in the refrigeration cycle that leads to breakage and even injury.
If there is a possibility of touching the fan during maintenance, make sure to turn
OFF the power before implementing the maintenance. Even if operations are
suspended, the fan of outdoor unit sometimes rotates, so if the fan rotates suddenly
while in contact with you may cause serious injury.

ABOUT THE UNIT2.
Precautions for using the R410A refrigerant2. 1.
Pay careful attention to the following points :
Since the working pressure is 1.6 times higher than that of R22 models, some of the
piping and installation and service tools are special. (See the table in the SPECIAL
TOOLS FOR R410A section.)
Especially, when replacing a conventional refrigerant (other than R410A) model
with a new refrigerant R410A model, always replace the conventional piping and
fl are nuts with the R410A piping and fl are nuts.
Models that use refrigerant R410A have a different charging port thread diameter
to prevent erroneous charging with R22, R407C and for safety. Therefore, check
beforehand. [The charging port thread diameter for R410A is 1/2 UNF 20 threads
per inch.]
Be more careful than the installation of the refrigerant (other than R410A) models,
not to enter foreign matters (oil, water, etc.) and other refrigerant into the piping.
Also, when storing the piping, securely seal the openings by pinching, taping, etc.
When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always charge from the liquid phase side
whose composition is stable.

refrigerants, the diameter of each port has been changed.
It is recommended to use a gauge manifold with a high
pressure display range -0.1 to 5.3 MPa and a low pressure
display range -0.1 to 3.8 MPa.
To increase pressure resistance, the hose material and
base size were changed.

Hoisting method
When hanging the outdoor unit and conveying it to installation location, hang the •
unit with rope by passing through the 4 opening holes on bottom of front and rear
side as shown in fi gure.
Use 2 ropes at least 8m long. If used shorter length, it may cause to damage to the •
unit
.
Use the suffi ciently strong rope to bear the unit’s weight.•
Place the protective board or fi ller cloth at the place where the cabinet may come •
into contact with rope to prevent from damages. Without using them, cabinet may
cause to damage or deform.
During the hanging unit, make sure to keep the unit level to prevent from falling.•
To prevent an unit swing accident or falling down of the unit, do not apply any •
impact to the unit when it is hanging.

To minimize vibration, do not install the outdoor unit directly on the ground.•
Instead, install it on top of a fi rm platform (such as concrete block). (Fig. B)
The foundation base should be able to support the product and the foot width of •
the product should be more than 46.5mm.
Depending on the installation condition, vibration during the operation of the unit •
may cause noise and vibration.
Install vibration-proofi ng materials (such as rubber pads).
Consider the removal space of the connection piping when installing the founda-•
tion.
Secure the equipment fi rmly with anchor bolts, washers, and nuts.•

CAUTION
When connecting multiple outdoor units, set the nearest outdoor unit to the indoor •
unit on the refrigerant pipe as the master unit.
When connecting multiple outdoor units, install the outdoor unit with the largest •
nominal system capacity nearest to the indoor unit on the refrigerant pipe, followed by those with less nominal system capacities.
[Capacity: Master ≥ Slave]
Always keep to the limit on the total amount of refrigerant. Exceeding the limit •
on the total amount of refrigerant when charging will lead to malfunction.
