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 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
3 (Freon gas weight per unit air volume) for facilitating calculation
n
Calculate refrigerant concentration
Refrigerant concentration =
Total amount of replenished refrigerant in refrigerant facility (kg)
Capacity of smallest room where indoor unit is installed (m 3 )
