Discharge air capacity is a converted value according to the suction condition of the compressor.
（
2
） Discharge pressure indicates gauge pressure.
（
3
）
Discharge air temperature varies depending on ambient temperature, load ratio etc.
The interphase voltage unbalance ratio of the power supply shall be within 1 %.
If the unbalance factor of the input current exceeds 20 % during the rated load operation, install AC reactor to the input side for improvement
of power supply cooperation. (The AC reactor is NOT the scope of supply from HITACHI)
（

）
When a unit operates at the pressure below the PQ wide mode range, size-UP may be required for separate dryer and/or filters. Contact
Hitachi authorized distributors.
（
6
） The compressor is not equipped with an earth leakage breaker. The earth leakage breaker should be provided by the customer.
（
7
） The appearance and specifi cations are subject to change without notifi cation.
（
