Note 1 : The cooling capacities and electrical characteristics are measured under the conditions specified by JIS B 8616
based on the reference piping length 7.5 m with 0 meter height.
Note 2 : The sound level is measured in an anechoic chamber in accordance with JIS B8616. Normally, the values
measured in the actual operating environment become larger than the indicated values due to the effects of
external sound.

6. REFRIGERANT R410A
This air conditioner adopts the new refrigerant HFC
(R410A) which does not damage the ozone layer.
(5) After completion of installation work, check to
make sure that there is no refrigeration gas
leakage.
The working pressure of the new refrigerant R410A is
1.6 times higher than conventional refrigerant (R22).
The refrigerating oil is also changed in accordance
with change of refrigerant, so be careful that water,

servicing time.
large volume of refrigerant is installed in a small
room, it is necessary to exercise care so that,
even when refrigerant leaks, its concentration
does not exceed the marginal level.
If the refrigerant gas leakage occurs and its
concentration exceeds the marginal level, an
oxygen starvation accident may result.
The next section describes the precautions for air
conditioner using the new refrigerant. Conforming to
contents of the next section together with the general
cautions included in this manual, perform the correct
and safe work.
(7) Be sure to carry out installation or removal
according to the installation manual.
Improper installation may cause refrigeration
trouble, water leakage, electric shock, fire, etc.
6-1. Safety During Installation/Servicing
As R410A’s pressure is about 1.6 times higher than
that of R22, improper installation/servicing may cause
a serious trouble. By using tools and materials exclu-
sive for R410A, it is necessary to carry out installation/
servicing safely while taking the following precautions
into consideration.
(8) Unauthorized modifications to the air conditioner
may be dangerous. If a breakdown occurs please
call a qualified air conditioner technician or
electrician.
Improper repair’s may result in water leakage,
electric shock and fire, etc.
(1) Never use refrigerant other than R410A in an air
conditioner which is designed to operate with
R410A.
6-2. Refrigerant Piping Installation
If other refrigerant than R410A is mixed, pressure 6-2-1. Piping materials and joints used
in the refrigeration cycle becomes abnormally

able for the refrigerant must be chosen and installed.
(2) Confirm the used refrigerant name, and use tools
and materials exclusive for the refrigerant R410A.
The refrigerant name R410A is indicated on the
visible place of the outdoor unit of the air condi-
tioner using R410A as refrigerant. To prevent
mischarging, the diameter of the service port
differs from that of R22
Furthermore, it is necessary to use clean copper pipes
and joints whose interior surfaces are less affected by
contaminants.
(1) Copper pipes
It is necessary to use seamless copper pipes
which are made of either copper or copper alloy
and it is desirable that the amount of residual oil is
less than 40 mg/10 m. Do not use copper pipes
having a collapsed, deformed or discolored
portion (especially on the interior surface).
Otherwise, the expansion valve or capillary tube
may become blocked with contaminants.
As an air conditioner using R410A incurs pressure
higher than when using R22, it is necessary to
choose adequate materials.
(3) If a refrigeration gas leakage occurs during
installation/servicing, be sure to ventilate fully.
If the refrigerant gas comes into contact with fire,
a poisonous gas may occur.
(4) When installing or removing an air conditioner,
do not allow air or moisture to remain in the
refrigeration cycle. Otherwise, pressure in the
refrigeration cycle may become abnormally high
so that a rupture of personal injury may be
caused.
Thicknesses of copper pipes used with R410A are
as shown in Table 6-2-1. Never use copper pipes
thinner than 0.8 mm even when it is available on
the market.

For copper pipes, flare joints or socket joints are
used. Prior to use, be sure to remove all
contaminants.
Socket joints are such that they are brazed for
connections, and used mainly for thick pipings
whose diameter is larger than 20 mm.
Thicknesses of socket joints are as shown in
Table 6-2-2.
a) Flare joints
Flare joints used to connect the copper pipes
cannot be used for pipings whose outer
diameter exceeds 20 mm. In such a case,
socket joints can be used.

d) Flare processing
Make certain that a clamp bar and copper pipe
have been cleaned.
By means of the clamp bar, perform the flare
processing correctly.
Use either a flare tool for R410A or conven-
tional flare tool.
Flare processing dimensions differ according to
the type of flare tool. When using a conven-
tional flare tool, be sure to secure “dimension A”
by using a gauge for size adjustment.
When performing the refrigerant piping installation,
care should be taken to ensure that water or dust does
not enter the pipe interior, that no other oil other than
lubricating oils used in the installed air conditioner is
used, and that refrigerant does not leak. When using
lubricating oils in the piping processing, use such
lubricating oils whose water content has been removed.
When stored, be sure to seal the container with an
airtight cap or any other cover.
(1) Flare Processing procedures and precautions
a) Cutting the pipe
∅D
A
By means of a pipe cutter, slowly cut the pipe
so that it is not deformed.
b) Removing burrs and chips
If the flared section has chips or burrs,
refrigerant leakage may occur. Carefully
remove all burrs and clean the cut surface
before installation.

(2) Flare connecting procedures and precautions
When it is strong, the flare nut may crack and
may be made non-removable. When choosing
the tightening torque, comply with values
designated by manufacturers. Table 6-2-7
shows reference values.
a) Make sure that the flare and union portions do
not have any scar or dust, etc.
b) Correctly align the processed flare surface with
the union axis.
Note:
c) Tighten the flare with designated torque by
means of a torque wrench. The tightening
torque for R410A is the same as that for
conventional R22. Incidentally, when the torque
is weak, the gas leakage may occur.
When applying oil to the flare surface, be sure to use
oil designated by the manufacturer. If any other oil is
used, the lubricating oils may deteriorate and cause
the compressor to burn out.

6-3.Tools
6-3-1. Required tools
The service port diameter of packed valve of the outdoor unit in the air conditioner using R410A is changed to
prevent mixing of other refrigerant. To reinforce the pressure-resisting strength, flare processing dimensions and
opposite side dimension of flare nut (For ∅12.70 copper pipe) of the refrigerant piping are lengthened.
The used refrigerating oil is changed, and mixing 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.

refrigerant in the cycle.
(For refrigerant charging, see the figure below.)
1 Never charge refrigerant exceeding the specified amount.
2 If the specified amount of refrigerant cannot be charged, charge refrigerant bit by bit in COOL mode.
3 Do not carry out additional charging.
When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in the
refrigeration cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the
specified amount is charged, and working pressure in the refrigeration cycle becomes abnormally high
pressure, and may cause a rupture or personal injury.

2 When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down.
It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant.
Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the
cylinder upside down if cylinder is not equipped with siphon.

R410A refrigerant is HFC mixed refrigerant.
Therefore, if it is charged with gas, the composition

6-5. Brazing of Pipes
1 Phosphor bronze brazing filler tends to react
with sulfur and produce a fragile compound
water solution, which may cause a gas leakage.
Therefore, use any other type of brazing filler at
a hot spring resort, etc., and coat the surface
with a paint.
6-5-1. Materials for brazing
(1) Silver brazing filler
Silver brazing filler is an alloy mainly composed of
silver and copper. It is used to join iron, copper or
copper alloy, and is relatively expensive though it
excels in solderability.
2 When performing brazing again at time of
servicing, use the same type of brazing filler.
(2) Phosphor bronze brazing filler
Phosphor bronze brazing filler is generally used to
join copper or copper alloy.
6-5-2. Flux
(1) Reason why flux is necessary
• By removing the oxide film and any foreign
matter on the metal surface, it assists the flow of
brazing filler.
(3) Low temperature brazing filler
Low temperature brazing filler is generally called
solder, and is an alloy of tin and lead. Since it is
weak in adhesive strength, do not use it for
refrigerant pipes.
• In the brazing process, it prevents the metal
surface from being oxidized.
• By reducing the brazing filler’s surface tension,
the brazing filler adheres better to the treated
metal.
– 19 –
(2) Characteristics required for flux
• Activated temperature of flux coincides with the
brazing temperature.
6-5-3. Brazing
As brazing work requires sophisticated techniques,
experiences based upon a theoretical knowledge, it
must be performed by a person qualified.
In order to prevent the oxide film from occurring in the
pipe interior during brazing, it is effective to proceed
with brazing while letting dry Nitrogen gas (N2) flow.
• Due to a wide effective temperature range, flux
is hard to carbonize.
• It is easy to remove slag after brazing.
• The corrosive action to the treated metal and
brazing filler is minimum.
• It excels in coating performance and is harmless
to the human body.
Never use gas other than Nitrogen gas.
(1) Brazing method to prevent oxidation
1 Attach a reducing valve and a flow-meter to the
Nitrogen gas cylinder.
As the flux works in a complicated manner as
described above, it is necessary to select an
adequate type of flux according to the type and
shape of treated metal, type of brazing filler and
brazing method, etc.
2 Use a copper pipe to direct the piping material,
and attach a flow-meter to the cylinder.
3 Apply a seal into the clearance between the
piping material and inserted copper pipe for
Nitrogen in order to prevent backflow of the
Nitrogen gas.
(3) Types of flux
• Noncorrosive flux
Generally, it is a compound of borax and boric
acid.
It is effective in case where the brazing
temperature is higher than 800°C.
4 When the Nitrogen gas is flowing, be sure to
keep the piping end open.
5 Adjust the flow rate of Nitrogen gas so that it is
lower than 0.05 m3/Hr or 0.02 Mpa (0.2 kgf/
cm2) by means of the reducing valve.
6 After performing the steps above, keep the
Nitrogen gas flowing until the pipe cools down
to a certain extent (temperature at which pipes
are touchable with hands).
• Activated flux
Most of fluxes generally used for silver brazing
are this type.
It features an increased oxide film removing
capability due to the addition of compounds

9-2. PRECAUTIONS FOR SAFETY
• Ensure that all Local, National and International regulations are satisfied.
• Read this “PRECAUTIONS FOR SAFETY” carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
New Refrigerant Air Conditioner Installation
CAUTION
• This air conditioner adopts the new HFC refrigerant (R410A) which does not destroy ozone layer.
The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its
pressure is approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant,
refrigerating oil has also been changed. Therefore, during installation work, be sure that water, dust, former
refrigerant, or refrigerating oil does not enter the refrigerating cycle.
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging
port of the main unit and installation tools are charged from those for the conventional refrigerant.
Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust
does not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance
force and impurity in it.
To Disconnect the Appliance from Main Power Supply
CAUTION
This appliance must be connected to the main power supply by means of a switch with a contact separation
of at least 3 mm.
The installation fuse (25A D type
) must be used for the power supply line of this conditioner.
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker 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 in a wrong way, electric parts may be damaged.
• When moving the air conditioner for the installation into another place, be very careful not to enter
any gaseous matter other than the specified refrigerant 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 may resultingly causes pipe burst and injuries on persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety
interlock switches.
• Exposure of unit to water or other moisture before installation may cause a short-circuit of electrical
parts.
Do not store it in a wet basement or expose to rain or water.
– 28 –

• Do not install in a place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• When the air conditioner is installed in a small room, provide appropriate measures to ensure that
the concentration of refrigerant leakage occur in the room does not exceed the critical level.
• Install the air conditioner securely in a location where the base can sustain the weight adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range,
noxious gas might generate.
• Electrical work must be performed by a qualified electrician in accordance with the Installation
Manual. Make sure the air conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified cables for wiring connect the terminals securely fix.To prevent external forces
applied to the terminals from affecting the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.
If a combustible gas leaks, and stays around the unit, a fire may occur.

9-10-8. Installation/Servicing Tools
<Changes in the product and components>
In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, the service port
diameter of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)
• In order to increase the pressure resisting strength of the refrigerant piping, flare processing diameter and size of opposite side of flare
nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)
New tools for R410A
New tools for R410A
Applicable to R22 model
Changes
Gauge manifold
As pressure is high, it is impossible to measure by means of conventional gauge.
In order to prevent any other refrigerant from being charged, each port diameter is
changed.
Charge hose
In order to increase pressure resisting strength, hose materials and port size are
changed (to 1/2 UNF 20 threads per inch).
When purchasing a charge hose, be sure to check the port size.
Electronic balance
for refrigerant charging
As pressure is hight and gasification speed is fast, it is difficult to read the
indicated value by means of charging cylinder, as air bubbles occur.
Torque wrench
(nominal diam. 1/2, 5/8)
The size of opposite sides of flare nuts have been increased. Incidentally, a
common wrench is used for nominal diameters 1/4 and 3/8.
By increasing the clamp bar’s receiving hole, strength of spring in the tool has
been improved.
Flare tool
(clutch type)
Gauge for projection adjustment
Vacuum pump adapter
Used when flare is made with using conventional flare tool.
Connected to the conventional vacuum pump. It is necessary to use an adapter to
prevent vacuum pump oil from flowing back to the charge hose.
The charge hose connecting part has two ports-one for conventional refrigerant
(7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil
(mineral) mixes with R410A a sludge may occur and damage the equipment.
Gas leakage detector
Exclusive for HFC refrigerant.
• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the U. S’s ARI specified rose
color (ARI color code: PMS 507).
• Also, the “charge port and packing for refrigerant cylinder” require 1/2 UNF 20 threads per inch corresponding to the charge hose’s port size.
