N O T E
• For outdoor unit installation information, please refer to the outdoor
unit Installation and operational manual.
• In “TYPE 1: Version for operation in DHW but with a remote tank”, the
required unit controller (PC-ARFHE) has to be ordered as accessory.
• In “TYPE 2: Version for operation with HITACHI DHW tank”,
the domestic hot water tank of model DHWS200S-2.7H2E and
DHWS260S-2.7H2E is required. The DHWT has to be ordered
separately. The unit controller (PC-ARFHE) is factory-supplied with
the DHWT (integrated in the font cover). The tank can be installed in
2 ways: on top of the indoor unit (integrated installation) or next to it.
In this second case, the specific accessory kit for installation (ATW-
FWP-02, ordered as an accessory) is required.
