About this detail

The refrigerant distribution network connects to an ARUM312DTE5 outdoor unit combining ARUM096DTE5 and ARUM216DTE5 models with an additional refrigerant charge of 51.70 lbs. The main liquid and gas lines connect through branch pipes ARCNB21 and branching joints ARBLB07121 to multiple PRHR043A header units. Pipe lengths and diameters are specified for each segment, including 3/4 inch by 1+1/8 inch by 3/8 inch runs over 110.0 feet and smaller distribution branches. Downstream lines connect to various indoor fan coil units including ARNU363M2A4, ARNU283M2A4, ARNU243M2A4, ARNU183M2A4, ARNU153M2A4, and ARNU093M2A4 models with specific cooling and heating capacities.
