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:
- 0.8 meter beneath indoor height center
- 1.5 meter from Discharge grille
The above data was measured in an anechoic
chamber. Please take into consideration reflected
sound of your specific site
