2 SAFETY PRECAUTIONS

• Ensure that all Local, National and International regulations are satisfied.

• Read these “SAFETY PRECAUTIONS” carefully before Installation.

• The precautions described below include 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 to the customer how to use and maintain the unit.

• Ask the customer to keep the Installation Manual together with the Owner’s Manual.

WARNING

• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.

Perform installation work properly according to the Installation Manual.

Inappropriate installation may result in water leakage, electric shock or fire.

• Be sure to connect earth wire. (grounding work)

Incomplete grounding cause an electric shock.

Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.

• Turn off the main power supply switch or breaker before attempting any electrical work and maintenance.

Make sure all power switches are off. Failure to do so may cause electric shock.

Use an exclusive power circuit for the air conditioner. Use the rated voltage.

• Connect the connecting wire correctly.

If the connecting wire is incorrect, electric parts may be damaged.

• When moving the air conditioner for installation to another place, be very careful not to allow the specified

refrigerant (R410A) to become mixed with any other gaseous body into the refrigeration cycle.

If air or any other gas mixes with the refrigerant, the gas pressure in the refrigeration cycle will become abnormally high and

it may result in the pipe bursting or personal injuries.

• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches.

• Do not touch the intake or aluminum fins of the outdoor unit.

Doing so may result in injury.

• Tighten the flare nut with a torque wrench in the specified manner.

Excessive tightening of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant

leakage.

• Install the air conditioner securely in a location where the base can sustain the weight of the unit 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 unit falling.

• 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 be generated.

• 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 may be generated.

• 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 only the specified wiring during the unit installation. Ensure that all terminals are securely fixed, so preventing

any external forces having a negative effect on the terminals.

• When the air conditioner cannot cool or heat a room well, contact the dealer from whom you purchased the air

conditioner as refrigerant leakage is considered as the cause.

In the case of repair that requires refill of refrigerant, ask service personnel about details of the repair.

The refrigerant used in the air conditioner is harmless.

Generally, the refrigerant does not leak. However, if the refrigerant leaks in a room and a heater or stove burner in the room

catches fire, it may generate toxic gas.

When you ask service personnel for repairing refrigerant leakage, confirm that the leakage portion has been completely

repaired.

• Conform to the regulations of the local electric company when wiring the power supply.

Inappropriate grounding may cause electric shock.

4 EN

Super Digital Inverter

• Do not install the air conditioner in a location that may be subjected to a risk of exposure to a combustible gas.

If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.

• Install the refrigerant pipe securely during the installation work before operating the air conditioner.

If the compressor is operated with the valve open and without the refrigerant pipe, the compressor sucks air and the

refrigeration cycle is overpressurized, which may cause a burst or injury.

• 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 with 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

rupturing, injury, etc.

CAUTION

• Do not climb onto or place objects on top of the outdoor unit.

You may fall or the objects may fall off of the outdoor unit and result in injury.

• Wear heavy gloves during the installation work to avoid injury.

To Disconnect the Appliance from the Main Power Supply

• This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.

• A 16 A installation fuse (all fuse types can be used) must be used for the power supply line of this conditioner.

3 INSTALLATION OF NEW REFRIGERANT AIR

CONDITIONER

CAUTION

New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE

LAYER.

R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure

of R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the new refrigerant, the

refrigerant oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or

refrigerant oil does not enter the new type refrigerant R410A air conditioner circuit.

To prevent mixing of refrigerant or refrigerant oil, the sizes of connecting sections of charging port on main unit and installation

tools are different from those of the conventional refrigerant units. Accordingly, special tools are required for the new refrigerant

(R410A) units. For connecting pipes, use new and clean piping materials with high pressure fittings made for R410A only, so

that water and/or dust does not enter.

Refrigerant Piping Connection

CAUTION

TAKE NOTE OF THESE 4 IMPORTANT POINTS BELOW

FOR PIPING WORK

1. Keep dust and moisture away from inside the connecting

pipes.

2. Tightly connect the connection between pipes and the

unit.

3. Evacuate the air in the connecting pipes using a

VACUUM PUMP.

4. Check for gas leaks at connection points.

Piping connection

Flaring

1. Cut the pipe with a pipe cutter.

Be sure to remove burrs that may cause a gas leak.

2. Insert a flare nut into the pipe, and then flare the pipe.

Use the flare nuts supplied with the air conditioner or

those for R410A.

Insert a flare nut into the pipe, and flare the pipe.

As the flaring sizes of R410A differ from those of

refrigerant R22, the flare tools newly manufactured for

R410A are recommended.

However, the conventional tools can be used by

adjusting the projection margin of the copper pipe.

Projection margin in flaring : B (Unit : mm)

Rigid (Clutch type)

Flaring dia. size : A (Unit : mm)

* In case of flaring for R410A with the conventional flare

tool, pull the tool out approx. 0.5 mm more than that for

R22 to adjust it to the specified flare size.

The copper pipe gauge is useful for adjusting the

projection margin size.

Tightening of Connecting Part

1. Align the centers of the connecting pipes and fully tighten

the flare nut with your fingers. Then fix the nut with a

wrench as shown in the figure and tighten it with a torque

wrench.

2. As shown in the figure, be sure to use two wrenches to

loosen or tighten the flare nut of the valve on the gas

side. If you use a single crescent, the flare nut cannot be

tightened to the required tightening torque.

On the other hand, use a single crescent to loosen or

tighten the flare nut of the valve on the liquid side.

(Unit: N•m)

CAUTION

1. Do not put the crescent wrench on the cap.

The valve may break.

2. If applying excessive torque, the nut may break

according to some installation conditions.

• After the installation work, be sure to check for gas leaks

of the pipe connections with nitrogen.

• Pressure of R410A is higher than that of R22 (Approx.

1.6 times).

Therefore, using a torque wrench, tighten the flare pipe

connecting sections that connect the indoor/outdoor units

at the specified tightening torque.

Incomplete connections may cause not only a gas leak,

but also trouble with the refrigeration cycle.

6 AIR PURGING



Airtight test

Before starting an airtight test, further tighten the spindle

valves on the gas side and liquid side.

Pressurize the pipe with nitrogen gas charged from the

service port to the design pressure (4.15 Mpa) to conduct the

airtight test. Perform gas leak checks using a leak tester for

the HFC refrigerant.

After the airtight test is completed, evacuate the nitrogen

gas.



Air Purge

With respect to the preservation of the terrestrial

environment, adopt “Vacuum pump” to purge air (Evacuate

air in the connecting pipes) when installing the unit.

• Do not discharge the refrigerant gas to the atmosphere to

preserve the terrestrial environment.

• Use a vacuum pump to discharge the air (nitrogen, etc.)

that remains in the set. If air remains, the capacity may

decrease.

For the vacuum pump, be sure to use one with a backflow

preventer so that the oil in the pump does not backflow into

the pipe of the air conditioner when the pump stops.

(If oil in the vacuum pump is put in an air conditioner

including R410A, it may cause trouble with the refrigeration

cycle.)

Vacuum pump

Use the vacuum pump, vacuum pump adapter, and gauge

manifold correctly referring to the manuals supplied with each

tool before using them.

Check that the vacuum pump oil is filled up to the specified line

of the oil gauge.

When air is not charged, check again whether the connecting

port of the discharge hose, which has a projection to push the

valve core, is firmly connected to the charge port.

Replenishing refrigerant

This model is a 20 m chargeless type that does not need to

have its refrigerant replenished for refrigerant pipes up to

20 m. When a refrigerant pipe longer than 20 m is used, add

the specified amount of refrigerant.

Refrigerant replenishing procedure

1. After vacuuming the refrigerant pipe, close the valves

and then charge the refrigerant while the air conditioner

is not working.

2. When the refrigerant cannot be charged to the specified

amount, charge the required amount of refrigerant from

the charge port of the valve on the gas side during

cooling.

Requirement for replenishing refrigerant

Replenish liquid refrigerant.

When gaseous refrigerant is replenished, the refrigerant

composition varies, which disables normal operation.

Adding additional refrigerant

• L: Pipe length

• The refrigerant need not be reduced for a 20 meter (or

less) refrigerant pipe.

How to wire

1. Connect the connecting wire to the terminal as identified

with their respective numbers on the terminal block of the

indoor and outdoor units.

H07 RN-F or 60245 IEC 66 (1.5 mm

or more)

2. When connecting the connecting wire to the outdoor unit

terminal, prevent water from coming into the outdoor unit.

3. Insulate the unsheathed cords (conductors) with

electrical insulation tape. Process them so that they do

not touch any electrical or metal parts.

4. For interconnecting wires, do not use a wire joined to

another on the way.

Use wires long enough to cover the entire length.

CAUTION

• An installation fuse must be used for the power supply

line of this air conditioner.

• Incorrect/incomplete wiring may lead to an electrical fire

or smoke.

• Prepare an exclusive power supply for the air conditioner.

• This product can be connected to the mains power.

Fixed wire connections :

A switch that disconnects all poles and has a contact

separation of at least 3 mm must be incorporated in the

fixed wiring.

8 EARTHING

WARNING

• Be sure to connect the earth wire. (grounding work)

Incomplete grounding may cause an electric shock.

Connect the earth line properly following applicable technical standards.

Connecting the earth line is essential to preventing electric shock and to reducing noise and electrical charges on the outdoor

unit surface due to the high-frequency wave generated by the frequency converter (inverter) in the outdoor unit.

If you touch the charged outdoor unit without an earth line, you may experience an electric shock.

9 FINISHING

After the refrigerant pipe, inter-unit wires, and drain pipe have been connected, cover them with finishing

tape and clamp them to the wall with off-the-shelf support brackets or their equivalent.

Keep the power wires and indoor/outdoor connecting wires off the valve on the gas side or pipes that have no heat insulator.

TEST RUN

• Turn on the leakage breaker at least 12 hours before starting a test run to protect the compressor during startup.

To protect the compressor, power is supplied from the 220-240 VAC input to the unit to preheat the compressor.

• Check the following before starting a test run:

• That all pipes are connected securely without leaks.

• That the valve is open.

If the compressor is operated with the valve closed, the outdoor unit will become overpressurized, which may damage the

compressor or other components.

If there is a leak at a connection, air can be sucked in and the internal pressure further increases, which may cause a burst

or injury.

• Operate the air conditioner in the correct procedure as specified in the Owner’s Manual.
