1. REQUIRED TOOLS FOR INSTALLATION WORK

2. SAFETY PRECAUTIONS

Installation should be in accordance with local and national electrical and building fire safety

regulations or codes.

WARNING

Indoor unit cassette type

10)

11) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect,

water may enter the room and damage the furniture.

12) For appliances with supplementary heaters, the minimum clearance from the appliance to

combustible is 50cm other wise, it will cause fire.

Selection of the installation location.

Select an installation location which is rigid and strong enough to support or hold the unit, also

for easy maintenance and repair.

Power supply connection to the room air conditioner.

Connect the power supply cord of the room air conditioner to the mains using one of the

following method.

Power supply point shall be the place where there is ease for access for the power

disconnection in case of emergency.

In some countries, permanent connection of this room air conditioner to the power supply is

prohibited.

Do not release refrigerant.

Do not release refrigerant during piping work for installation, reinstallation and during repairing

a refrigeration parts. Take care of the liquid refrigerant. it may cause frostbite.

4) Installation work. It may need two people to carry out the installation work.

Do not install this appliance inalaundry room or other location where water may drip from the

ceiling, etc.

The temperature of refrigerant circuit will be high, please keep the interconnection cable away

from the copper tube.

Important information for the used refrigerant

This product has the fluorinated gas which is listed in Kyoto protocol.

It is forbidden to release to air.

Refrigerant type: R410a Volume of GWP: 2088; tonnes CO2 equivalent

GWP=Global Warming Potential

Attention:

1) The fluorinated greenhouse gases are contained in non-hermetically sealed equipment.

2) Installs, services, maintains, repairs, checks for leaks or decommissions equipment and product

recycling should be carried out by natural persons that hold relevant certificates.

3) For equipment that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO 2

equivalent or more, but of less than 50 tonnes of CO 2 equivalent: the leakage check should be

performed at least every 12 months; or where a leakage detection system is installed, at least every

24 months.

Flare tool

(clutch type)

Gauge for

adjustment

As the working pressure is high, it is impossible to

measure the working pressure using conventional

gauges. In order to prevent any other refrigerant from

being charged, the port diameters have been changed.

In order to increase pressure resisting strength, hose

materials and port sizes have been changed (to 1/2

UNF 20 threads per inch). When purchasingacharge

hose, be sure to confirm the port size.

As working pressure is high and gasification speed is

fast, it is difficult to read the indicated value by means

of charging cylinder, as air bubbles occur.

The size of opposing 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 size,

strength of spring in the tool has been improved.

New Refrigerant Air Conditioner Installation

THIS AIR CONDITIONERADOPTS THENEWHFC REFRIGERANT (R410A) WHICH DOES

NOT DESTROYOZONELAYER. 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 of refrigerant R22. Accompanied with the adoption of the new refrigerant, the

refrigeration machine oil has also been changed. Therefore, during installation work, be sure that

water, dust, former refrigerant, or refrigeration machine oil does not enter into the new type

refrigerant R410A air conditioner circuit.

To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of

charging port on main unit and installation tools are different from those used for 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. Moreover, do not use the existing piping because

there are some problems with pressure fittings and possible impurities in existing piping.

Changes in the product and components

In air conditioners using R410A, in order to prevent any other refrigerant from being accidentally

charged, the service port diameter size 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 opposing flare nuts sizes have been changed. (for copper pipes with nominal

dimensions 1/2 and 5/8)

CAUTION

Used when flare is made by using conventional flare

tool.

Indoor unit cassette type

Vacuum pump

adapter

Gas leakage

detector

Connected to conventionalvacuumpump. It is

necessary to use an adapter to prevent vacuum pump

oil from flowing back into 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.

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" requires 1/2 UNF 20 threads per inch

corresponding to the charge hose's port size.

Exclusive for HFC refrigerant.

Indoor unit

Do not install the cassette in a room where gasses, acids or inflammable products are stored,

in order to avoid damage to the aluminum and copper evaporators and the internal plastic

parts.

Do not install the cassette inaworkshop orakitchen. Oil vapor attracted by the treated air

could form deposits on the cassette evaporators and modify their performance or damage the

cassette's internal plastic parts.

3. Do not install the cassette in a laundry, or a room where steam is produced.

The appliance must be positioned so that the plug is accessible.

5. Installing the cassette will be easier with the use of a fork lift truck. Use the packing base by

placing it between the cassette and the truck forks.

6. It is recommended to install the cassette, as far as possible, in the centre of the room, in order

to optimize treated air distribution.

7. For the chosen location, check that the distribution grilles can be removed and that there is

sufficient space available for maintenance and repairs.

Indoor unit cassette type

1. The location must allow easy servicing and provide good air circulation as shown in fig 4.

2. The unit may be suspended from a wall by a bracket (Optional) or located inafree standing posi-

tion on the floor (preferably slightly elevated).

3. If the unit is suspended, ensure that the bracket is firmly connected and the wall is strong enough

to withstand vibrations.

4. Unit location should not disturb neighbors with noise or exhaust air stream.

5. Place the mounting pads under the unit legs.

6. Refer to figure 4 for allowed installation distances.

When the unit is installed on a wall, install the drain connector hose and drain plug as shown in

fig1 and fig2.

7. INSTALLATION OF THE INDOOR UNIT

Deciding ceiling opening size

1. Gird ceiling installation situation (60x60 standard ceiling):

Because this unit is a mini-cassette, there is no need to make an opening cut on the ceiling,

just remove one piece of ceiling panel.

2. Hard ceiling installation situation:

Create the ceiling opening required for installation, below shows the relationship of the ceiling

opening to unit and the panel (Fig 5)
