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/m
