Piping Length

Long distance pipelines can be laid for distribution throughout the building. Pipes in the system can be laid up to a total distance of 310 meters with the condensing unit’s ability to connect with up to 29 fan coils or 130% of the cooling capacity.

External Static Pressure

Adjust the hot air ventilation force to increase operational efficiency. In cases where the condensing unit is installed in a confined space or wind is blowing against the front of the condensing unit causing obstruction of heat ventilation, the wind force may be adjusted up to 30 PA to increase heat ventilation efficiency.

Quiet Mode

Quiet with reduced operation noise: the condensing unit operation noise is reduced by 15% (in the PUMY-P225YKM model) from 58 dB to only 48 dB.

* Quiet Mode adjustment requires a Diff SW Board, which reduces the cooling efficiency.
