5 EQUIPMENT DAMAGE HAZARDF ailure to follow this caution may result in equipmentdamage or improper not bury more than 36 in. (914 mm) of refrigerantpipe in the ground. If any section of pipe is buried, theremust be a 6 in. (152 mm) vertical rise to the valveconnections on the outdoor units. If more than therecommended length is buried, refrigerant may migrateto the cooler buried section during extended periods ofsystem shutdown. This causes refrigerant slugging andcould possibly damage the compressor at start INSTRUCTIONS R 410a Ductless Split System.
