✻'-H' in the indoor units indicates that the unit pipes come out of the top of the unit (50/60Hz, fit to order).
✻PFD-type indoor units cannot be connected to outdoor units other than the ones specified above.
✻PFD-type indoor units and other types of indoor units cannot coexist in the same refrigerant system.
When using a PFD-P500VM-A as an indoor unit, connect 2 PUD-P250YMF-C outdoor units to each
indoor unit and operate with a built-in remote control for the indoor unit.
✻1: Bold line indicates refrigerant piping (gas/liquid). This system consists of 2 refrigerant circuits.
✻2: Indicates TB3-type transmission line that connects the indoor and outdoor units.
This system consists of 2 refrigerant circuits.
✻3: Indicates TB7-type transmission line that allows the unit to communicate with the controller.
When using a PFD-P250VM-A as an indoor unit, connect an outdoor unit PUD-P250YMF-C to each
indoor unit and operate with a built-in remote control for the indoor unit.

2-4. Correction by refrigerant piping length
To obtain a decrease in cooling/heating capacity due to refrigerant piping extension, multiply by the capacity
correction factor based on the refrigerant piping equivalent length in the table below.
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.50 ✕number of bent on the piping)m
