pipe
1. Pipe "A" diameter (between indoor and branch pipe depends on the indoor pipe)
Indoor (x100W) Gas pipe
18~28 Ø9.52
32~56 Ø12.7
63~160 Ø15.88
226-300 Ø25.4
450-600 Ø28.58
Note:
• If the distance between the unit and the nearest branch;:: 15m, Pipe "A" should be enlarged:
(1) If the capacity of indoor unit is 5 5.6kW, the gas pipe changes to Ø15.88 and the liquid pipe changes to Ø9.52.
(2) If 5.6kW < the capacity of indoor unit is< 16.8kW, the gas pipe changes to 019.05 and the liquid pipe changes to Ø9.52.
(3) If the capacity of indoor unit is 16.8kw, the liquid pipe changes to Ø12.7.
• The first sub-manifold distance from the longest indoor unit piping length ;:: 40 meters
(1) The first sub-manifold to the nearest indoor unit main pipe (gas /liquid pipe) must increase as per the specification
(2) The distance between the nearest indoor unit distance between the indoor unit :5 40 meters\
