not avoided, could result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation that may result in minor or

moderate injury or damage to property.

WARNING

To avoid getting an electric shock, never touch the electrical components soon after the

power supply has been turned off. After turning off the power, always wait 10 minutes or

more before you touch the electrical components..

Installation of this product must be done by experienced service technicians or

professional installers only in accordance with this manual. Installation by non-

professional or improper installation of the product might cause serious accidents such

as injury, water leakage, electric shock, or ﬁ re. If the product is installed in disregard of

the instructions in this manual, it will void the manufacturer’s warranty.

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 an electric shock or

a ﬁ re.

If refrigerant leaks when you are working, ventilate the area. If the leaking refrigerant is

exposed to a direct ﬂ ame, it may produce a toxic gas.

Installation must be performed in accordance with regulations, codes, or standards for

electrical wiring and equipment in each country, region, or the installation place.

Do not use this equipment with air or any other unspeciﬁ ed refrigerant in the refrigerant

lines. Excess pressure can cause a rupture.

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.

When installing or relocating the air conditioner, do not mix gases other than the

speciﬁ ed refrigerant (R32) to enter the refrigerant cycle.

If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to

an abnormally high value and cause rupture, injury, etc.

For appropriate working of the air conditioner, install it as written in this manual.

To connect indoor unit and outdoor unit, or indoor unit and branch box, use air

conditioner piping and cables available through your local distributor. This manual

describes proper connections using such installation set.

Do not modify power cable, use extension cable or branch wiring. Improper use may

cause electric shock or ﬁ re by poor connection, insufﬁ cient insulation or over current.

Do not purge the air with refrigerants but use a vacuum pump to vacuum the

installation.

There is no extra refrigerant in the outdoor unit for air purging.

Do not use means to accelerate the defrosting process or to clean, other than those

recommended by the manufacturer.

The appliance shall be stored in a room without continuously operating ignition sources

(for example: open ﬂ ames, an operating gas appliance or an operating electric heater.

Do not pierce or burn.

Be aware that refrigerants may not contain an odour.

Using the same vacuum pump for different refrigerants may damage the vacuum pump

or the unit.

Use a clean gauge manifold, vacuum pump and charging hose for R32 or R410A

exclusively.

WARNING

Do not modify this unit, such as opening a hole in the cabinet.

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 rupture and even injury.

CAUTION

This unit must be installed by qualiﬁ ed personnel with a capacity certiﬁ cation of handling

refrigerant ﬂ uids. Refer to regulation and laws in use on installation place.

Install the unit by following local codes and regulations in force at the place of

installation, and the instructions provided by the manufacturer.

This unit is part of a set constituting an air conditioner. The unit must not be installed

alone or be installed with non-authorized device by the manufacturer.

When installing pipes shorter than 3 m, sound of the outdoor unit will be transferred to

the indoor unit, which will cause large operating sound or some abnormal sound.

To protect the persons, earth( ground) the unit correctly, and use the power cable

combined with an Earth Leakage Circuit Breaker (ELCB).

The units are not explosion proof, and therefore should not be installed in explosive

atmosphere.

This unit contains no user-serviceable parts. Always consult experienced service

technicians for repairing.

When moving or relocating the air conditioner, consult experienced service technicians

for disconnection and reinstallation of the unit.

Children should be monitored to ensure they do not play with the device.

This appliance is not intended for use by persons (including children) with reduced

physical, sensory or mental capabilities, or lack of experience and knowledge, unless

they have been given supervision or instruction concerning use of the appliance by a

person responsible for their safety. Children should be supervised to ensure that they do

not play with the appliance.

Do not touch the aluminum ﬁ ns of heat exchanger built-in the indoor or outdoor unit to

avoid personal injury when you install or maintain the unit.

Do not place any other electrical products or household belongings under indoor unit or

outdoor unit. Condensation dripping from the unit might get them wet, and may cause

damage or malfunction of your property.

Precautions for using R32 refrigerant

The basic installation work procedures are the same as conventional refrigerant (R410A,

R22) models.

However, pay careful attention to the following points:

WARNING

Since the working pressure is 1.6 times higher than that of refrigerant R22 models,

some of the piping and installation and service tools are special. (Refer to “2.1. Special

tools for R32 (R410A)”.)

Especially, when replacing a refrigerant R22 model with a new refrigerant R32 model,

always replace the conventional piping and ﬂ are nuts with the R32 and R410A piping

and ﬂ are nuts on the outdoor unit side.

For R32 and R410A, the same ﬂ are nut on the outdoor unit side and pipe can be used.

Models that use refrigerant R32 and R410A have a different charging port thread

diameter to prevent erroneous charging with refrigerant R22 and for safety. Therefore,

check beforehand. [The charging port thread diameter for R32 and R410A is 1/2 inch.]

Be more careful than R22 so that foreign matter (oil, water, etc.) does not enter the

piping.

Also, when storing the piping, securely seal the opening by pinching, taping, etc.

(Handling of R32 is similar to R410A.)

from sources such as compressors or fans.

6.Detection of ﬂ ammable refrigerants

• Under no circumstances shall potential sources of ignition be used in the searching

for or detection of refrigerant leaks.

• A halide torch (or any other detector using a naked ﬂ ame) shall not be used.

7.Leak detection methods

• Electronic leak detectors shall be used to detect ﬂ ammable refrigerants, but the

sensitivity may not be adequate, or may need re-calibration. (Detection equipment

shall be calibrated in a refrigerant-free area.)

• Ensure that the detector is not a potential source of ignition and is suitable for the

refrigerant used.

• Leak detection equipment shall be set at a percentage of the LFL of the refrigerant

and shall be calibrated to the refrigerant employed and the appropriate percentage

of gas (25 % maximum) is conﬁ rmed.

• Leak detection ﬂ uids are suitable for use with most refrigerants but the use of

detergents containing chlorine shall be avoided as the chlorine may react with the

refrigerant and corrode the copper pipe-work.

• If a leak is suspected, all naked ﬂ ames shall be removed/extinguished.

• If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall

be recovered from the system, or isolated (by means of shut off valves) in a part of

the system remote from the leak.

Oxygen free nitrogen (OFN) shall then be purged through the system both before

and during the brazing process.

2. ABOUT THIS PRODUCT

2.1. Special tools for R32 (R410A)

Tool name Change from R22 to R32(R410A)

Gauge manifold

Pressure is high and cannot be measured with a conven-

tional (R22) gauge. To prevent erroneous mixing of other

refrigerants, the diameter of each port has been changed.

It is recommended to use gauge with seals -0.1 to 5.3 MPa

(-1 to 53 bar) for high pressure.

-0.1 to 3.8 MPa (-1 to 38 bar) for low pressure.

Charge hose

To increase pressure resistance, the hose material and base

size were changed.(R32/R410A)

Vacuum pump

A conventional vacuum pump can be used by installing a

vacuum pump adapter.

(Use of a vacuum pump with a series motor is prohibited.)

Gas leakage detector

Special gas leakage detector for HFC refrigerant R32 or

R410A.

Copper pipes

It is necessary to use seamless copper pipes 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 value or

capillary tube may become blocked with contaminants.

As an air conditioner using R32(R410A) incurs pressure higher than when using R22, it is

necessary to choose adequate materials.

Thicknesses of copper pipes used with R32(R410A) are as shown in the table below.

Never use copper pipes thinner than 0.8 mm even when it is available on the market.

Thicknesses of Annealed Copper Pipes

8.Removal and evacuation

• When breaking into the refrigerant circuit to make repairs – or for any other

purpose –conventional procedures shall be used.

However, it is important that best practice is followed since ﬂ ammability is a consid-

eration.

The following procedure shall be adhered to:

• remove refrigerant

• purge the circuit with inert gas

• evacuate

• purge again with inert gas

• open the circuit by cutting or brazing

• The refrigerant charge shall be recovered into the correct recovery cylinders.

• The system shall be “ﬂ ushed” with OFN to render the unit safe.

• This process may need to be repeated several times.

• Compressed air or oxygen shall not be used for this task.

• Flushing shall be achieved by breaking the vacuum in the system with OFN and

continuing to ﬁ ll until the working pressure is achieved, then venting to atmosphere,

and ﬁ nally pulling down to a vacuum.

• This process shall be repeated until no refrigerant is within the system.

• When the ﬁ nal OFN charge is used, the system shall be vented down to atmos-

pheric pressure to enable work to take place.

• This operation is absolutely vital if brazing operations on the pipe work are to take

place.

• Ensure that the outlet for the vacuum pump is not close to any ignition sources and

there is ventilation available.

9.Charging procedures

• In addition to conventional charging procedures, the following requirements shall be

followed.

- Ensure that contamination of different refrigerants does not occur when using

charging equipment.

- Hoses or lines shall be as short as possible to minimize the amount of refrigerant

contained in them.

- Cylinders shall be kept upright.

- Ensure that the refrigeration system is earthed prior to charging the system with

refrigerant.

- Label the system when charging is complete (if not already).

- Extreme care shall be taken not to overﬁ ll the refrigeration system.

• Prior to recharging the system it shall be pressure tested with OFN.

• The system shall be leak tested on completion of charging but prior to commission-

ing.

• A follow up leak test shall be carried out prior to leaving the site.

10.Decommissioning

• Before carrying out this procedure, it is essential that the technician is completely

familiar with the equipment and all its details.

• It is recommended good practice that all refrigerants are recovered safely.

• Prior to the task being carried out, an oil and refrigerant sample shall be taken in

case analysis is required prior to re-use of reclaimed refrigerant.

• It is essential that electrical power is available before the task is commenced.

a) Become familiar with the equipment and its operation.

ant cylinders;

• all personal protective equipment is available and being used correctly;

• the recovery process is supervised at all times by a competent person;

• recovery equipment and cylinders conform to the appropriate standards.

d) Pump down refrigerant system, if possible.

e) If a vacuum is not possible, make a manifold so that refrigerant can be removed

from various parts of the system.

f) Make sure that cylinder is situated on the scales before recovery takes place.

g) Start the recovery machine and operate in accordance with manufacturer’s

instructions.

h) Do not overﬁ ll cylinders. (No more than 80 % volume liquid charge).

i) Do not exceed the maximum working pressure of the cylinder, even temporarily.

j) When the cylinders have been ﬁ lled correctly and the process completed, make

sure that the cylinders and the equipment are removed from site promptly and

all isolation valves on the equipment are closed off.

k) Recovered refrigerant shall not be charged into another refrigeration system

unless it has been cleaned and checked.

WARNING

To install a unit that uses R32 refrigerant, use dedicated tools and piping materials

that have been manufactured speciﬁ cally for R32(R410A) use. Because the pressure

of R32 refrigerant is approximately 1.6 times higher than R22, failure to use dedicated

piping material or improper installation can cause rupture or injury. Furthermore, it can

cause serious accidents such as water leakage, electric shock, or ﬁ re.

Do not use a vacuum pump or refrigerant recovery tools with a series motor, since it

may ignite.

2.2. Power

WARNING

Always use a special branch circuit and install a special receptacle to supply power to

the room air conditioner.

Use a circuit breaker and receptacle matched to the capacity of the air conditioner.
