Safety Precautions

ENGLISH

Installation

• Always check for gas (refrigerant) leakage after installation or repair of product.

- Low refrigerant levels may cause failure of product.

• Install the drain hose to ensure that water is drained away properly.

- A bad connection may cause water leakage.

• Keep level even when installing the product.

- To avoid vibration or water leakage.

• 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.

• Use two or more people to lift and transport the product.

- Avoid personal injury.

• Do not install the product where it will be exposed to sea wind (salt spray) directly.

- It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins,

could cause product malfunction or inefficient operation.

Operation

• Do not expose the skin directly to cool air for long periods of time. (Don't sit in the draft.)

- This could harm to your health.

• Do not use the product for special purposes, such as preserving foods, works of art, etc. It is a consumer
air conditioner, not a precision refrigeration system.

- There is risk of damage or loss of property.

Model Designation

Product information

- Product Name : Air conditioner.

- Additional Information : serial number is refer to the barcode on the product.

- Max allowable pressure High side : 4.2 MPa / Low side : 2.4 MPa

- Refrigerant : R410A

Model Designation

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/m

Limiting concentration

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.
