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.
1)
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.
2)
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.
3)
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.
5)
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.

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.

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.

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.
1.
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.
2.
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.
4.
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.

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
