NOTE:
1. The nominal cooling and heating capacity is the
combined capacity of the HITACHI standard split
system, and are based on the JIS 158616.

2. The Sound Pressure Level is based on the following
conditions:
– 1.5 meter beneath the Unit
– Voltage of the power source for the indoor fan motor
is 220V.
The above data was measured in an anechoic chamber
so that reflected sound should be taken into
consideration when installing the unit.
