Safety Precautions
CAUTION
■ Installation
Always check for gas (refrigerant) leakage
after installation or repair of product.
• Low refrigerant levels may cause
failure of product.
Do not install the product where the noise
or hot air from the outdoor unit could damage the neighborhoods.
• It may cause a problem for your
neighbors.
Install the drain hose to ensure that
water is drained away properly.
• A bad connection may cause
water leakage.
Use two or more people to lift and
transport the product.
• Avoid personal injury.
Keep level even when installing
the product.
• To avoid vibration or water leakage.

In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting
hood on a cooking table has sufficient capacity so that it
draws oily steam which should not flow into the suction
of the air conditioner.
• Make enough distance from a cooking room to install
the air conditioner in such a place where it may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.

• Connect the main drain pipe to the exterior and
leave it provisionally until the test comes to an end.
• Feed water to the flexible drain hose and check the
piping for leakage.
• Be sure to check the drain pump for normal operation and noise when electrical wiring is complete.

CAUTION:
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: 0.0000158 lb/inch3(R410A)
■ Calculate refrigerant concentration
Total amount of replenished refrigerant in refrigerant facility (lb)
Refrigerant concentration =
Capacity of smallest room where indoor unit is installed (inch3)
