∗This compressor has a 4-pole motor.

The value when compressor frequency (Hz) is measured by a clamp meter is twice the compressor revolution number (rps).

∗This data is cycle data obtained by combining a four-way ceiling cassette simultaneous twin at a target pipe length. Data will change depending on the mounted pipe length or combination with the indoor unit.
