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 reli-
ably to determine whether or not further pre-
cautions 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 num-
ber of equipment and other adjacent process-
es and the length of time for which an opera-
tor exposed to the noise. Also, the permissi-
ble 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
3
(Freon gas weight per unit air volume)
for facilitating calculation.
Limiting concentration: 0.44kg/m
3
(R410A)
Calculate refrigerant concentration
Total amount of replenished refrig-
Refrigerant
erant in refrigerant facility (kg)
=
concentration
Capacity of smallest room where
indoor unit is installed (m
