Ductless vs ACID vs SightGlass/MoistureIndicator vs Suction FilterDriers

R22 &r410A have pretty normal procedurers for detecting moisture( SG/MI)( close your eyes Spence) and then cleaning up any moisture before it causes ACIDS, then also cleanup rules and regs for getting rid of any ACID'S that gets created . What does your "Ductless Split" mfrg have to say about that?!?! What do they say about SGMI & FD's in the first place????

Great question. With so many minisplit systems getting installed incorrectly, there most likely will be a requirement for a dryer install during a service.
Some split units have only a low pressure tap for gauges. Others have a high side too. I wonder if the ones with L/H taps can have the dryers while the others cant. Just a thought.
Please keep us informed.:NYplumber:0 -
Well
A little birdie once told me that some manufacturers, just simply don't approve products made by other manufacturers, for use in their systems. Regardless if they work or not.
Switching subjects, a product I have recently been researching has taken some unexpected twists. Apparently there are some very large manufacturers who use this product at their factories for assembly, but refuse to formally approve the use of this product in their systems.
I found that to be mildly interesting.

Sight Glass

the liquid line, stricly speaking isn't, in most ductless systems
so mosly they instruct you not to use either.
the smaller refrigerant line is acually part of the cold coil since its after the metering device.
this is why, as I have always understood it, they tell you not to use sight glasses or liquid line filter/dryers.There was an error rendering this rich post.

Ductless vs Acid
What do you do when there is a burnout on a ductless system? You change out the comp and ? Ductless are not immune to having/creating acids which kill comp's . I know about the little line being lo side and insulated, so a LLFD is out . Has anyone heard of repeated comp failurers on Ductless Split's ? Why not a SG/MI on the little line? There is no "restriction" to a SG/MI.0
