Can anyone explain the metering device set up in a Carrier 50TJQ 012 501GA. About 10 yrs. old.
2-3/8" liquid lines ,one heat one cool, go to 3/4" headers with eight 3/8" outlets on each of two cicuits. Expansion happens at each of eight inlets to the indoor coil . Are there orifaces in all 32 branches? I am about to try Carrier's site for an explanation but no guaranties.- posted
