Refrigerant piping
IMPORTANT: Do not bury refrigerant piping
underground.
It is recommended that the refrigerant piping for all
commercial split systems include a liquid line solenoid
valve, a liquid line filter drier and a sight glass.
For refrigerant lines longer than 75 lineal ft, a liquid line
solenoid valve installed at the indoor unit and a suction
accumulator are required. Refer to the Refrigerant
Specialties Part Numbers table.
