Hey guys I'm working on a fujitsu 1.5 ton system which had a restriction right before the strainer into the capillary tube. I suspected the restriction to be within the capillary tube so I cut it out out along with the strainer only to learn the restriction was right before the strainer.
The restriction is clear now. I know these small residential minisplits in most cases use capillary tubes with strainers only.. can I substitute the strainer in this small system with a a filter drier ? If so, how do I size it for my system (r-22) ? If not, can these strainers be purchased ?
