NOTE:
1. The nominal cooling and heating capacity is the combined capacity of
the HITACHI standard split system, and are based on the ISO 5151.
2. The Sound Pressure Level is based on the
following conditions:
- 1.4 meter from Discharge grille
The above data was measured in an
anechoic chamber. Please take into
