This R32 VRF Shut-Off Valve Kit connects between the outdoor and indoor units and supports connection to 1–8 indoor units.
It is designed exclusively for use with R32 VRF heating or cooling outdoor units and is required when indoor units are installed in small rooms to isolate refrigerant flow to all of the connected indoor units when a leak is detected.
An input connection allows a Sensor & Alarm Kit (PAC-SL72SA-E) to be installed with the shut-off valve kit, while an output connection provides an external alarm dry-contact signal.
