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/m3(Freon gas weight per unit air volume)
for facilitating calculation
nCalculate refrigerant concentration

concentration (kg/m3)
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 characteris-
tics 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 evalua-
tion of the hazard and risk.
