PRECAUTIONS FOR SAFETY
PRECAUTIONS FOR SAFETY
WARNING
• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• Do not install in a place which cannot bear the weight of the unit.
Personal injury and property damage can result if the unit falls.
• Before doing the electrical work, attach an approved plug to the power supply cord.
Also, make sure the equipment is properly earthed.
• Appliance shall be installed in accordance with national wiring regulations.
If you detect any damage, do not install the unit. Contact your dealer immediately.
• Do not use any refrigerant different from the one specified for complement or replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion of the product or an injury to your
body.
DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF.
FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE
DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
• TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M) FROM
HEAT SOURCES SUCH AS RADIATORS, HEATERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY CAREFUL NOT TO GET THE SPECIFIED
REFRIGERANT (R410A) WITH ANY OTHER GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN THE
REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY HIGH AND IT RESULTINGLY CAUSES BURST
OF THE PIPE AND INJURIES ON PERSONS.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION WORK, IMMEDIATELY LET FRESH AIR
INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF POISONOUS GAS.
CAUTION
• Exposure of unit to water or other moisture before installation could result in electric shock.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully for possible damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of the unit or where noise and
discharged air might disturb neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation.
• The manufacturer shall not assume any liability for the damage caused by not observing the description of this manual.
• Before installation, please read these precautions for safety carefully.
• Be sure to follow the precautions provided here to avoid safety risks. The symbols and their meanings are shown below.
WARNING : It indicates that incorrect use of this unit may cause severe injury or death.
CAUTION : It indicates that incorrect use of this unit may cause personal injury (*1), or property damage (*2).
*1: Personal injury means a slight accident, burn, or electrical shock which does not require admission or repeated hospital treatment.
*2: Property damage means greater damage which affects assets or resources.
For general public use
Power supply cord and connecting cable of appliance use shall be at least polychloroprene sheathed flexible cord (design H07RN-F) or cord designation
60245 IEC66. (Shall be installed in accordance with national wiring regulations.)
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm in all poles.
CAUTION To disconnect the appliance from the main power supply
New refrigerant air conditioner installation
CAUTION
• THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membranes, and oils because the pressure of R410A refrigerant is approx.
1.6 times of refrigerant R22. As well as the adoption of this new refrigerant, refrigerating machine oil has also been changed. Therefore, during installation
work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter the refrigeration cycle of a new-refrigerant air conditioner.
To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on the main unit are different from those for the
conventional refrigerant, and different size tools are also required. For connecting pipes, use new and clean piping materials with high pressure withstand
capabilities, designed for R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as its pressure withstand
may be insufficient and may contain impurities.
REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER
Please make absolutely sure that the installation of this appliance is reported to the local power supplier before installation. If you experience any problems
or if the installation is not accepted by the supplier, the service agency will take adequate countermeasures.

Evacuating
After the piping has been connected to the indoor unit, you can perform the
air purge together at once.
AIR PURGE
Evacuate the air in the connecting pipes and in the indoor unit using a
vacuum pump. Do not use the refrigerant in the outdoor unit. For details,
see the manual of the vacuum pump.
Be sure to use a vacuum pump with counter-flow prevention function so that
inside oil of the pump does not flow backward into pipes of the air conditioner
when the pump stops.
(If oil inside of the vacuum pump enters the air conditioner, which use R410A,
refrigeration cycle trouble may result.)
1. Connect the charge hose from the manifold valve to the service port of the
packed valve at gas side.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the gauge manifold valve.
4. Operate the vacuum pump to start evacuating. Perform evacuating for
about 15 minutes if the piping length is 20 meters.
(15 minutes for 20 meters)
(assuming a pump capacity of 27 liters per minute) Then confirm that the
compound pressure gauge reading is –101 kPa (–76 cmHg).
5. Close the low pressure side valve handle of the gauge manifold valve.
6. Open fully the valve stem of the packed valves (both gas and liquid sides).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
Using a vacuum pump
CAUTION
• KEEP IMPORTANT 5 POINTS FOR PIPING WORK.
(1) Take away dust and moisture (inside of the connecting pipes).
(2) Tighten the connections (between pipes and unit).
(3) Evacuate the air in the connecting pipes using a VACUUM PUMP.
(4) Check gas leak (connected points).
(5) Be sure to fully open the packed valves before operation.
Packed valve handling precautions
• Open the valve stem all the way out, but do not try to open it beyond the
stopper.

Work instructions
The existing R22 and R407C piping can be reused for
inverter R410A product installations.
WARNING
Confirming the existence of scratches or dents on
the existing pipes and confirming the reliability of
the pipe strength are conventionally referred to the
local site.
If the specified conditions can be cleared, it is
possible to update existing R22 and R407C pipes
to those for R410A models.
Basic conditions needed to reuse existing
pipes
Check and observe the presence of three conditions in
the refrigerant piping works.
1. Dry (There is no moisture inside of the pipes.)
2. Clean (There is no dust inside of the pipes.)
3. Tight (There are no refrigerant leaks.)
Restrictions for use of existing pipes
In the following cases, the existing pipes should
not be reused as they are. Clean the existing pipes
or exchange them with new pipes.
1. When a scratch or dent is heavy, be sure to use new
pipes for the refrigerant piping works.
2. When the existing pipe thickness is thinner than the
specified “Pipe diameter and thickness,” be sure to
use new pipes for the refrigerant piping works.
yThe operating pressure of R410A is high (1.6 times
that of R22 and R407C). If there is a scratch or dent
on the pipe or a thinner pipe is used, the pressure
strength may be inadequate, which may cause the
pipe to break in the worst case.
* Pipe diameter and thickness (mm)
Pipe outer diameter Ø6.4 Ø9.5 Ø12.7
Thickness R410A 0.8 0.8 0.8
R22 (R407C)
yIn case the pipe diameter is Ø12.7 mm or less and
the thickness is less than 0.7 mm, be sure to use new
pipes for the refrigerant piping works.
3. When the outdoor unit was left with the pipes
disconnected, or the gas leaked from the pipes and
the pipes were not repaired and refilled.
yThere is the possibility of rain water or air, including
moisture, entering the pipe.
4. When refrigerant cannot be recovered using a
refrigerant recovery unit.
yThere is the possibility that a large quantity of dirty
oil or moisture remains inside the pipes.
5. When a commercially available dryer is attached to the
existing pipes.
yThere is the possibility that copper green rust has
been generated.
6. When the existing air conditioner is removed after
refrigerant has been recovered.
Check if the oil is judged to be clearly different from
normal oil.
yThe refrigerator oil is copper rust green in color:
There is the possibility that moisture has mixed with
the oil and rust has been generated inside the pipe.
yThere is discolored oil, a large quantity of residue,
or a bad smell.
yA large quantity of shiny metal dust or other wear
residue can be seen in the refrigerant oil.
7. When the air conditioner has a history of the
compressor failing and being replaced.
yWhen discolored oil, a large quantity of residue,
shiny metal dust, or other wear residue or mixture of
foreign matter is observed, trouble will occur.
8. When temporary installation and removal of the air
conditioner are repeated such as when leased etc.
9. If the type of refrigerator oil of the existing air
conditioner is other than the following oil (Mineral oil),
Suniso, Freol-S, MS (Synthetic oil), alkyl benzene
(HAB, Barrel-freeze), ester series, PVE only of ether
series.
yThe winding-insulation of the compressor may
deteriorate.
NOTE
The above descriptions are results have been confirmed
by our company and represent our views on our air
conditioners, but do not guarantee the use of the existing
pipes of air conditioners that have adopted R410A in
other companies.
Curing of pipes
When removing and opening the indoor or outdoor unit for
a long time, cure the pipes as follows:
yOtherwise rust may be generated when moisture or
foreign matter due to condensation enters the pipes.
yThe rust cannot be removed by cleaning, and new
pipes are necessary.
Placement
location Term Curing manner
Outdoors 1 month or more Pinching
Less than 1 month Pinching or taping
Indoors Every time
Are there scratches or dents on the existing pipes?
Is it possible to operate the existing air conditioner?
yAfter the existing air conditioner is operated in cooling
mode for approx. 30 minutes or longer,* recover the
refrigerant.
yFor cleaning the pipes and recovering oil
yRefrigerant recovery: Pump down method
yRemove the existing air conditioner from the piping
and carry out flushing (nitrogen pressure 0.5 MPa) to
remove any remains inside of the pipe.
Note: In case of twin pipes, also be sure to flush the
branching pipe.
Connect the indoor / outdoor units to the existing pipe.
yUse a flare nut attached to the main unit for the indoor
/ outdoor units. (Do not use the flare nut of the existing
pipe.)
yRe-machine the flare machining size to size for R410A.
y(Airtight test), Vacuum dry, Refrigerant charge, Gas
leak check
Test run
Was largely discolored oil or a large quantity
of remains discharged? (When the oil deteriorates,
the color of the oil changes to a muddy
or black color.)
Existing pipes: Cannot be used.
yUse new pipes.
Clean the pipes or use new pipes.
