The refrigerant used by this air conditioner is the R410A.
Check the used refrigerant name and use tools and materials of the parts which match with it.
For the products which use R410A refrigerant, the refrigerant name is indicated at a position on
the outdoor unit where is easy to see.
To prevent miss-charging, the route of the service port is changed from one of the former R22.
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.
For an air conditioner which uses R410A, never use other refrigerant than R410A.
For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.
If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating
cycle and an injury due to breakage may be caused.
Do not charge refrigerant additionally.
If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the
refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over
the specified standard amount is charged and an abnormal high pressure is applied to the inside
of the refrigerating cycle resulted in cause of breakage or injury.
Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute
vacuuming, and then newly recharge the specified amount of liquid refrigerant.
In this time, never charge the refrigerant over the specified amount.
When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other
than R410A into the specified refrigerant.
If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating
cycle resulted in cause of injury due to breakage.
After installation work, check the refrigerant gas does not leak.
If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such
as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.
Never recover the refrigerant into the outdoor unit.
When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device.
The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as
breakage or injury is caused.
After repair work, surely assemble the disassembled parts, and connect and lead the removed
wires as before.
Perform the work so that the cabinet or panel does not catch the inner wires.
If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is
caused at user’s side.
After the work has finished, be sure to use an insulation tester set (500V Megger) to check the
resistance is 1MΩ or more between the charge section and the non-charge metal section
(Earth position).
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.
When the refrigerant gas leaks during work, execute ventilation.
If the refrigerant gas touches to a fire, poisonous gas generates.
A case of leakage of the refrigerant and the closed room full with gas is dangerous because a
shortage of oxygen occurs. Be sure to execute ventilation.
When the refrigerant gas leaks, find up the leaked position and repair it surely.
If the leaked position cannot be found up and the repair work is interrupted, pump-down and
tighten the service valve, otherwise the refrigerant gas may leak into the room.
The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove
though the refrigerant gas itself is innocuous.
When installing equipment which includes a large amount of charged refrigerant such as a multi
air conditioner in a sub-room, it is necessary that the density does not the limit even if the
refrigerant leaks.
If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.
Tighten the flare nut with a torque wrench in the specified manner.
Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may
result in refrigerant leakage.
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not slack.
For the installation/moving/reinstallation work, follow to the Installation Manual.
If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or
fire is caused.

Installation
Once the repair work has been completed, check for refrigerant leaks, and check the insulation
resistance and water drainage.
Then perform a trial run to check that the air conditioner is running properly.
After repair work has finished, check there is no trouble. If check is not executed, a fire, electric
shock or injury may be caused. For a check, turn off the power breaker.
After repair work (installation of front panel and cabinet) has finished, execute a test run to check
there is no generation of smoke or abnormal sound.
If check is not executed, a fire or an electric shock is caused. Before test run, install the front
panel and cabinet.
Check the following matters before a test run after repairing piping.
• Connect the pipes surely and there is no leak of refrigerant.
• The valve is opened.
Running the compressor under condition that the valve closes causes an abnormal high
pressure resulted in damage of the parts of the compressor and etc. and moreover if there is
leak of refrigerant at connecting section of pipes, the air is suctioned and causes further
abnormal high pressure resulted in burst or injury.
Only a qualified installer (∗1) or qualified service person (∗1) is allowed to relocate the air
conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual
since a fire, electric shocks, injury, water leakage, noise and/or vibration may result.
Check the following items after reinstallation.
1) The earth wire is correctly connected.
2) The power cord is not caught in the product.
3) There is no inclination or unsteadiness and the installation is stable.
If check is not executed, a fire, an electric shock or an injury is caused.
When carrying out the pump-down work shut down the compressor before disconnecting the
refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left open and the compressor still
operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to
an abnormally high level, and possibly resulting in reputing, injury, etc.
When the service panel of the outdoor unit is to be opened in order for the compressor or the
area around this part to be repaired immediately after the air conditioner has been shut down, set
the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the
service panel.
If you fail to heed this warning, you will run the risk of burning yourself because the compressor
pipes and other parts will be very hot to the touch. In addition, before proceeding with the repair
work, wear the kind of insulated heat-resistant gloves designed to protect electricians.
When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor,
inverter or the areas around these parts to be repaired immediately after the air conditioner has
been shut down, set the circuit breaker to the OFF position, and then wait at least 10 minutes
before opening the service panel.
If you fail to heed this warning, you will run the risk of burning yourself because the fan motor,
reactor, inverter heat sink and other parts will be very hot to the touch.
In addition, before proceeding with the repair work, wear the kind of insulated heat-resistant
gloves designed to protect electricians.
Only a qualified installer (∗1) or qualified service person (∗1) is allowed to install the air
conditioner. If the air conditioner is installed by an unqualified individual, a fire, electric shocks,
injury, water leakage, noise and/or vibration may result.
Before starting to install the air conditioner, read carefully through the Installation Manual, and
follow its instructions to install the air conditioner.
Do not install the air conditioner in a location that may be subject to a risk of expire to a
combustible gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.
Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure
themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit
while the air conditioner is running.
Install a circuit breaker that meets the specifications in the installation manual and the stipulations
in the local regulations and laws.
Install the circuit breaker where it can be easily accessed by the qualified service person (∗1).
Do not place any combustion appliance in a place where it is directly exposed to the wind of air
conditioner, otherwise it may cause imperfect combustion.

New Refrigerant (R410A)
This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer.
1. Safety Caution Concerned to New Refrigerant
The pressure of R410A is high 1.6 times of that of the former refrigerant (R22).
Accompanied with change of refrigerant, the refrigerating oil has been also changed.
Therefore, be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into the
refrigerating cycle of the air conditioner with new refrigerant during installation work or service work.
If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident.
Use the tools and materials exclusive to R410A to purpose a safe work.
2. Cautions on Installation/Service
1) Do not mix the other refrigerant or refrigerating oil.
For the tools exclusive to R410A, shapes of all the joints including the service port differ from those of
the former refrigerant in order to prevent mixture of them.
2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools which are
specified for R410A.
3) In the installation time, use clean pipe materials and work with great attention so that water and others
do not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc.
Use the clean pipes.
Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.)
4) For the earth protection, use a vacuum pump for air purge.
5) R410A refrigerant is azeotropic mixture type refrigerant.
Therefore use liquid type to charge the refrigerant. (If using gas for charging, composition of the
refrigerant changes and then characteristics of the air conditioner change.)
3. Pipe Materials
For the refrigerant pipes, copper pipe and joints are mainly used.
It is necessary to select the most appropriate pipes to conform to the standard.
Use clean material in which impurities adhere inside of pipe or joint to a minimum.
1) Copper pipe
<Piping>
The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type.
When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe
without seam” and one with bonded oil amount 40mg/10m or less.
Also do not use crushed, deformed, discolored (especially inside) pipes.
(Impurities cause clogging of expansion valves and capillary tubes.)
<Flare nut>
Use the flare nuts which are attached to the air conditioner unit.
2) Joint
The flare joint and socket joint are used for joints of the copper pipe.
The joints are rarely used for installation of the air conditioner.
However clear impurities when using them.

4. Tools
1. Required Tools for R410A
Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary,
etc. Accordingly, the tools to be used are classified into the following three types.
1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))
2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)
3) Tools commonly used for R410A and for conventional refrigerant (R22)
The table below shows the tools exclusive for R410A and their interchangeability.

General tools (Conventional tools can be used.)
In addition to the above exclusive tools, the following equipments which serve also for R22 are necessary
as the general tools.
1) Vacuum pump. Use vacuum pump by
attaching vacuum pump adapter. 7) Screwdriver (+, –)
2) Torque wrench 8) Spanner or Monkey wrench
3) Pipe cutter 9) Hole core drill
4) Reamer 10) Hexagon wrench (Opposite side 4mm)

SET DATA 2
1) Based on the difference between Ta and Ts, the operation
frequency is instructed to the outdoor unit.
2) Cooling operation
Every 90 seconds, the room temperature difference
between temperature detected by Ta and Ts and the
varied room temperature value are calculated to obtain
the correction value of the frequency command and then
the present frequency command is corrected.
Ta (n) – Ts (n) : Room temp. difference
n : Counts of detection
Ta (n-1) – Ts (n) : Varied room temp. value
n – 1 :
Counts of detection of 90 seconds before
3) Heating operation
Every 1 minute (60 sec.), the room temperature differ-
ence between temperature detected by Ta and Ts and the
varied room temperature value are calculated to obtain
the correction value of the frequency command and then
the present frequency command is corrected.
Ts (n) – Ta (n) : Room temp. difference
n : Counts of detection
Ta (n) – Ta (n – 1) : Varied room temp. value
n – 1 : Counts of detection of 1 minute before
4) Dry operation
The frequency correction control is same as those of the
cooling operation.
However the maximum frequency is limited to approxi-
mately “S6”.
Note) When LOW is set up, the maximum frequency is
limited to approximately “SB”.
