For the products which use R32 refrigerant, the refrigerant name is indicated at a position on
the outdoor unit where is easy to see.

T
Be careful for miss-charging since a charging port of R32 is the same diameter as that of R410A.

o prevent miss-charging, the route of the service port is changed from one of the former R22.

For an air conditioner which uses R32, never use other refrigerant than R32.
For an air conditioner which uses other refrigerant (R22, R410A etc.), never use R32.

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 R32 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 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, it may generate noxious gases,
causing a fire.

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.

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.

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.

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 par ts 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.

If t

he 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.
When gas touches to fire such as fan heater, stove or cocking stove, it may generate noxious
gases, causing a fire 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.

6. REFRIGERANT R32

This air conditioner adopts the new refrigerant HFC
(R32) which does not damage the ozone layer.

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.

6-1. Safety During Installation/Servicing

The basic installation servicing work procedures are
the same as conventional R410A models.
As R32’s pressure is about 1.6 times higher than that
of R22, improper installation/servicing may cause a
serious trouble. By using tools and materi-als exclusive
for R32, it is necessary to carry out installation/
servicing safely while taking the following precautions
into consideration.

1. Never use refrigerant other than R32 in an air
conditioner which is designed to operate with R32.
If other refrigerant than R32 is mixed, pressure in
the refrigeration cycle becomes abnormally high,
and it may cause personal injury, etc. by a rupture.

2. Confirm the used refrigerant name, and use tools
and materials exclusive for the refrigerant.
The refrigerant name R32 is indicated on the visible
place of the outdoor unit of the air conditioner using
R32 as refrigerant. To prevent mischarging, the
diameter of the service port differs from that of R22.
R32 and other HFCs are heavier than air, and
therefore they are inclined to settle near the floor
surface.
If the gas fills up the room or the bottom part of a
room, it may also cause oxygen deficiency and may
reach its combustion concentration.

In order to prevent oxygen deficiency and R32
combustion, keep the room well-ventilated for a
healthy work environment.

In particular, using HFCs in a basement r

oom or
confined area creates a higher risk; be sure to
furnish the room with local exhaust ventilation.
If a refrigerant leak is confirmed in a room an
inadequately ventilated location, do not use a flame
until the area has been ventilated appropriately and
the work environment has been improved.
The same applies in case of brazing, ensure
appropriate ventilation to prevent oxygen deficiency
and R32 combustion.
Check that there are no dangerous or combustible
items nearby, and ensure a fire extinguisher is close
at hand.
Keep a sufficient distance away from causes of fire
(ignition sources) such as gas-burning equipment
and electric heaters in places where installation,
repairs, or similar work on air-conditioning
equipment is performed.

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 moisture dust or oil to remain in the
refrigeration cycle. Otherwise, pressure in
the refrigeration cycle may become abnormally high
so that a rupture or personal injury may be caused.

5. After completion of installation work, check to make
sure that there is no refrigeration gas leakage.
If the refrigerant gas leaks into the room, coming
into contact with fire in the fan-driven heater, space
heater, etc., a poisonous gas may occur

6. When an air conditioning system charged with a
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.

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.

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.

6-2. Refrigerant Piping Installation

6-2-1. Piping Materials and Joints Used

For the refrigerant piping installation, copper pipes
and joints are mainly used. Copper pipes and joints
suitable for the refrigerant must be chosen and
installed. 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 R32 incurs pres-sure
higher than when using R22, it is necessary to
choose adequate materials.

Thicknesses of copper pipes used with R32 are as
shown in Table 3-2-1. Never use copper pipes
thinner than 0.8 mm even when it is available on
the market.

2. Joints

For copper pipes, flare joints or socket joints are used. Prior to use, be sure to remove all contaminants.

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.
Sizes of flare pipe ends, flare joint ends and flare nuts are as shown in Tables 3-2-3 to 3-2-6 below.

b) Socket Joints

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.

6-2-2. Processing of Piping Materials

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 than lubricating oils used in the installed air-water heat pump 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

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.

c) Insertion of Flare Nut

FILE NO. SVM-18041

ØD

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 R32 or conven­tional flare tool.

Flare processing dimensions differ according
to the type of flare tool. When using a con­ventional flare tool, be sure to secure “dimen­sion A” by using a gauge for size adjustment.

2. Flare Connecting Procedures and Precautions

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.
c) Tighten the flare with designated torque by means of a torque wrench. The tightening torque for R32 is

the same as that for conventional R22. Incidentally, when the torque is weak, the gas leakage may occur.
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 3-2-7 shows reference values.

NOTE :

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-water heat pump using R32 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 Ø12.7 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 R32 (Those which cannot be used for conventional refrigerant (R22))

2. Tools exclusive for R32, but can be also used for conventional refrigerant (R22)

3. Tools commonly used for R32 and for conventional refrigerant (R22)
The table below shows the tools exclusive for R32 and their interchangeability.

Connect the charge hose to packed valve service
port at the outdoor unit’s gas side.

Recover the refrigerant, and check no refrigerant
remains in the equipment.

(For refrigerant charging, see the figure below.)

Connect the charge hose to the vacuum pump
adapter.

Open fully both packed valves at liquid and gas
sides.

Place the handle of the gauge manifold Low in the
fully opened position, and turn on the vacuum pump’s
power switch. Then, evacuating the refrigerant in the
cycle.

When the compound gauge’s pointer has indicated
–0.1 Mpa (–76 cmHg), place the handle Low in the
fully closed position, and turn off the vacuum pump’s
power switch.

Keep the status as it is for 1 to 2 minutes, and ensure
that the compound gauge’s pointer does not return.

Set the refrigerant cylinder to the electronic balance,
connect the connecting hose to the cylinder and the
connecting port of the electronic balance, and charge
liquid refrigerant.

6-4. Recharging of Refrigerant

When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the
following steps.

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.
