PFD-type indoor units cannot be connected to outdoor units other than the ones specified above.

It is necessary to rewrite the S/W on the control circuit board of the outdoor unit connected to the PFD-type indoor units.

PFD-type indoor units and other types of indoor units cannot coexist in the same refrigerant system.

It is necessary to change pulley and V-belt when using it by the power supply frequency 60Hz.

For restrictions when the PFD-type indoor units are connected (related to the system), see P21.
