NOTE
1. Because the diameter of this ball valve is approximately the same as the inner diameter of the connecting cop-
per tube, correction for pressure loss is not necessary.
2. Airtightness must be 3.6 MPa or more.
It is recommended that the ball valve is installed at each outdoor unit (gas tube and liquid tube), in order to
prevent refrigerant from being released into the atmosphere if the outdoor unit is eventually replaced.
Cooling capacity after distribution
