✻ 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.

When using a PFD-P500VM-E as an indoor unit, connect an outdoor unit PUHY-P500YGM-A 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.

• Cooling

Equivalent length = (Actual piping length to the farthest indoor unit) + (0.50 ✕ number of bent on the piping)m

• How to obtain piping equivalent length
