indoor unit weight.
• Where the floor is not significantly inclined.
• Where nothing blocks the air passage.
• Where condensate can be properly drained.
• Where sufficient clearance for installation and
maintenance can be ensured.
• Where there is no possibility of flammable gas
leakage.
• Where optimum air distribution can be ensured.
• Where piping between indoor and outdoor units
is possible within the allowable limit (Refer to the
installation manual of the outdoor unit.)
• Keep the indoor and outdoor unit, power cable
and transmission wiring, at least 1m from TVs
and radios, to prevent distorted pictures and

1. Use the installationmount for installation. Check
whether the wall is strong enough to bear the
weight of the unit or not. if there is a risk,
reinforce the wall before installing the unit.
2. The unit requires a minimum 100 mm clearance
on the underside for air intake. Also, ensure the
unit is level when installed so that drainage
flows smoothly. If inclined, water can leak.
3. By a state of the wall, operating sound may
become bigger.

HEAT INSULATION
1. Use the heat insulation material for the refrigerant
piping which has an excellent heat-resistance
(over 120°C).
2. Precautions in high humidity circumstance:
This air conditioner has been tested according to
the "ISO Conditions with Mist" and confirmed that
there is not any default. However, if it is operated
for a long time in high humid atmosphere (dew
point temperature: more than 23°C), water drops
are liable to fall. In this case, add heat insulation
material according to the following procedure:
• Heat insulation material to be prepared... EPDM
(Ethylene Propylene Diene Methylene)-over
120°C the heat-resistance temperature.
• Add the insulation over 10mm thickness at high
humidity environment.
After inspecting pipe joints for gas leakage, be sure
to insulate wit the accessory joint insulation for
fitting while referrig to the figure. (Fasten both ends
with clamps)

Drain piping work
• Drain piping must have downward (1/50 to 1/100): be sure not to provide up-and-down slope to
prevent reverse flow.
• During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit.
• The outside diameter of the drain connection on the inddor unit is 21mm.
Piping material: Polyvinyl chloride pipe 25mm and pipe fittings
• Be sure to install heat insulation on the drain piping
Heat insulation material: Polyethylene foam with thickness more than 10 mm.
• If converging multiple dranin pipes, install according to the procedure shown below.
Slope downwards at a gradient
of at least 1/100
• After piping work is finished check drainage flows smothly.
• Be sure to insulate all indoor units.

Indoor Unit
Installation
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner. As
for the method of wiring, be guided by the circuit diagram posted on the inside
of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screws which fasten the wiring in the casing of electrical fittings are liable
to come loose from vibrations to which the unit is subjected during the course
of transportation. Check them and make sure that they are all tightly fastened.
(If they are loose, it could give rise to burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the
rated voltage marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources
specification. (Particularly note the relation between cable length and
thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point, fuse breaking,
disturbance by the normal function of an overload protection device.
• Proper starting power is not given to the compressor.

Airborne Noise Emission
The A-weighted sound pressure emitted by this product is below 70 dB.
** The noise level can vary depending on the site.
The figures quoted are emission level and are not necessarily safe working levels. Whilst there is a
correlation between the emission and exposure levels, this cannot be used reliably to determine
whether or not further precautions are required. Factor that influence the actual level of exposure of the
workforce include the characteristics of the work room and the other sources of noise, i.e. the number
of equipment and other adjacent processes and the length of time for which an operator exposed to the
noise. Also, the permissible exposure level can vary from country to country. This information, however,
will enable the user of the equipment to make a better evaluation of the hazard and risk.
Limiting concentration
Limiting concentration is the limit of Freon gas concentration where immediate measures can be
taken without hurting human body when refrigerant leaks in the air. The limiting concentration shall
be described in the unit of kg/m3 (Freon gas weight per unit air volume) for facilitating calculation
Limiting concentration: 0.44kg/m3 (R410A)
