• 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.

PRECAUTIONS FOR SAFETY

CAUTION New Refrigerant Air Conditioner Installation

• 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.

ENGLISH

CAUTION To Disconnect the Appliance from 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.

The installation fuse (25A D type

) must be used for the power supply line of this conditioner.

WARNINGS

• 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 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.

PRECAUTIONS FOR SAFETY

• After unpacking the unit, examine it carefully if there are possible damage.

• 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.

• 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.

SELECTION OF INSTALLATION PLACE

WARNING

• Install the air conditioner at enough strong place to withstand the weight of the unit.

If the strength is not enough, the unit may fall down resulting in injury.

• Perform a specified installation work to guard against an earth quake.

An incomplete installation can cause accidents by the units failing and dropping.

• Install the air conditioner at a height 2.5m or more from the floor.

If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous because you may contact with revolving fan or active electricity.

CAUTION

• Using the attached drain hose thermal insulator, lap the connecting section and the drain hose without clearance, and then tighten with two handing band so that thermal insulator does not open.

• Covering the attached drain hose thermal insulator, lap the thermal insulator (procured locally) to the drain pipe without clearance.

Fit the attached hose band to the end of the hose, lay down the knob, and then tighten hose band.

Drain pan

Attached drain hose

Confirm that soft hose is pushed in up to the end of the drain pan.

Connection of drain pipe

• Connect the hard vinyl chloride pipe (procured

locally) to the mounted drain hose which was attached.

• In case of taking pipe from the left side

• In case of taking pipe from the left side, exchange

the plug from left to right. Push in the plug of which end is not sharp up to the end.

REFRIGERANT PIPING AND EVACUATING

Refrigerant Piping

• The connecting sections of the refrigerant pipes are provided at the positions in the figure below.

Upper side

Right

Rear side

* When using the drain up kit sold

separately, the pipe can be drawn out only from the upper side.

1. Use copper pipe with 0.8 mm or more thickness.

(In case pipe size is Ø15.9, with 1.0mm or more.)

2. Flare nut and flare works are also different from

those of the conventional refrigerant. Take out the flare nut attached to the main unit of the air conditioner, and use it.

CAUTION

IMPORTANT 4 POINTS FOR PIPING WORK

1. Remove dust and moisture from the inside of

the connecting pipes.

2. Tight connection (between pipes and unit)

3. Evacuate the air in the connecting pipes using

VACUUM PUMP.

4. Check the gas leakage. (Connected points)

Flaring

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 projection margin of the copper pipe.

• Tightening torque of flare pipe connections

Pressure of R410A is higher than that of R22. (Approx. 1.6 times) Therefore, using a torque wrench, tighten the flare pipe connecting sections which connect the indoor and outdoor units of the specified tightening torque.

Incorrect connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.

Align the centers of the connecting pipes and tighten the flare nut as far as possible with your fingers. Then tighten the nut with a spanner and torque wrench as shown in the figure.

Piping with outdoor unit

Open the valve fully

• Shape of valve differs according to the outdoor unit. For details of installation, refer to the Installation

Manual of the outdoor unit.

Air purge

Using a vacuum pump, perform vacuuming from the charge port of valve of the outdoor unit.

For details, follow to the Installation Manual attached to the outdoor unit.

• Never use the refrigerant sealed in the outdoor unit for air purge.

REQUIREMENT

For the tools such as charge hose, etc., use those manufactured exclusively for R410A.

Refrigerant amount to be added

For addition of the refrigerant, add refrigerant “R410A” referring to the attached Installation Manual of outdoor unit.

Be sure to use a scale to charge the refrigerant of specified amount.

Open the valve of the outdoor unit fully. A 4mmhexagonal wrench is required for opening the valve.

For details, refer to the Installation Manual attached to the outdoor unit.

Gas leak check

Check with a leak detector or soap water whether gas leaks or not, from the pipe connecting section or cap of the valve.

REQUIREMENT

Use a leak detector manufactured exclusively for HFC refrigerant (R410A, R134a, etc.).

Thermal insulation process

Apply thermal insulation for the pipes separately at liquid side and gas side.

For the thermal insulation to the pipes at gas side, be sure to use the material with heat-resisting temperature 120°C or higher.

Using the attached thermal insulation material, apply the thermal insulation to the pipe connecting section of the indoor unit securely without gap.

REQUIREMENT

• Charging an excessive or too little amount of

refrigerant causes a trouble of the compressor. Be sure to charge the refrigerant of specified amount.

• A personnel who charged the refrigerant should

write down the pipe length and the added refrigerant amount in the nameplate attached to the service panel of the outdoor unit. It is necessary to troubleshoot the compressor and refrigeration cycle malfunction.

REQUIREMENT

Apply the thermal insulation to the pipe connecting section of the indoor unit securely up to the root without exposure of the pipe. (The pipe exposed to the outside causes water leak.)
