What It Means
- Primary R-32 refrigerant leak detection; high-speed fan operates2minutes to determine leak again.

VRF / VRV: VRF indoor unit (indoor)
An alarm sounds, and the product does not work. This is intended to determine whether there is a leak or not, as R-32 refrigerant is sensed. The indoor unit determines again whether or not there is a refrigerant leak while operating for 2 minutes using Fan mode (specifically High speed). If there is no refrigerant leak, the indoor unit stops operating, the error is cleared and the product can operate normally. Note: The R-32 sensor, embedded in the indoor unit, reacts not only to R-32 refrigerant but also to high-concentration chemicals (e.g. organic solvents, hair spray and paint).
