EQUIPMENT DAMAGE
Do not bury more than 36 in. (914 mm) of refrigerant pipe in the ground. If any section of pipe is
buried, there must be a 6 in. (152 mm) vertical rise to the valve connections on the outdoor units. If
more than the recommended length is buried, refrigerant may migrate to the cooler buried section
during extended periods of system shutdown. This causes refrigerant slugging and could possibly
damage the compressor at start−up.
