I can tell you how I lost gas & oil .
I insulated both copper refrigerant lines , except the last foot or so . I had left that " bare " so I could cut to length & flare the ends .
I had the system up and running OK . However , both lines and the brass service valves were sweating , a lot ( late June ) .
I proceeded to finish insulating the bare metal . But I dumbed up and wiggled the small line enough to cause it to leak , at the flare nut . Unfortunately , I did not notice it , then . :-)
Latter that day , the unit quit working . Went outside and noticed oil on the concrete . This was on the weekend . Was not able to buy a jug of R410a until Monday . Or get in touch with of factory technical assistance until Monday .
I had obsessed about the loss of oil , all weekend . The technical support guy asked me how much oil I lost ? I described the puddle on the concrete . He told me not to worry , a little oil on concrete will spread out to a scary size puddle . He also told me the condensers are shipped with enough oil to accommodate the max length of line set , listed in the specifications .
When I told him I had the min 15 foot line set , he assured me I was OK .
Anyway , I re-did the flare , vacuumed the system down and weighed out the specified charge of R410a .
I bought a roll of cork insulating tape at Johnstone supply and CAREFULLY finished insulating the service valves and remainder of the copper lines .
Praise the Lord !
It worked and was still working ( in HP ) mode , a few minutes ago . When I was in the living room .
God bless

PS This illustrates than many of my problems are self inflicted . :-(
I know quite a few ways of doing things , that do not work ! :-(
