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(R410A)

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
