• Heating conditions: Inlet/outlet water temperature: 30/35 ºC; Outdoor ambient temperature (DB/WB): 7/6 ºC.
• The compressor data shown in the tables below are based on a combined capacity of 100% of the power supplied.
• The "Maximum current" shown in the above table is the maximum total unit running current at the following conditions:
- Supply voltage: 90% of the rated voltage.
- Unit capacity: 100% at maximum operating conditions.
• The power supply cables must be sized to cover this maximum current value.
• Specifications in these tables are subject to change without notice in order that HITACHI may bring the latest innovations to their
customers.
• Please refer to the general information, cautions and notes regarding protective devices (CB, ELB) throughout the
"9.3 Electrical connection" chapter.
