Notes: *1. If the operational capacity of indoor units is more than
130%, low airflow operation is enforced in all the indoor
units. This limitation can be abolished through field setting.
*2. When outdoor-air processing units (FXMQ-MF) and
standard indoor units are connected, the total connection
capacity of the outdoor-air processing units (FXMQ-MF)
must not exceed 30% of the capacity index of the outdoor
units. And the connection ratio must not exceed 100%.
*3. When connecting the hydrobox, to prevent temporary
water temperature drop on the secondary side of the
hydrobox at the time of defrosting or when the indoor unit
starts/stops, and to prevent freezing, connect the indoor
unit with 50% or more capacity of the outdoor unit.
