    OFF TOPIC ALERT
    Just had Mitsubishi Tech support tell me, in writing, that they specify a:

    - 600 psi leak test for minimum of 24 hrs,
    - then triple evac,
    - two hour below 500microns,
    - then a 1 hr rise assessment.

    He sent me this in writing. I am officially whining to their engineering dept to reconsider as this makes no sense for a new 1-2 ton resi install. It turns every sale into a two-day install...that should impact sales or every install will not be to spec. On a complex Multi-branch setup, ok, I get it, but not a one to one mini-split.

    Look at it this way, it makes warranty calls for refrigeration problems disappear, until the evap starts leaking.

    I've been in a Mitsubishi class that has said Nylog is ok. I also did a Fujitsu class that said Nylog is ok. I also wonder why your rep said no to it?

    His exact words were"that stuff always gets into the system and finds a LEV". Maybe he's seen it where some jackwagons use 1/2 the bottle on a flare...

    I use the bottles that my contact lens cleaner comes in, two different sizes, one has a screw on cap & the other has a snap top cap. Never had a leaking problem.

    I keep ref. oil, rust buster & a light lubricating oil in them. Works great!

    That is what I was thinking. But Nylog is just refer oil as far as I know.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    I can almost guarantee that no one does it that way. I worked for a Diamond Dealer and that was never done.
