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.
