    Thanks, good video! One thing to mention, it's good to pump some oil into the separator before starting the compressors. The float can bang around and get damaged if running the compressors without oil under the float. If you look in the ac&r separator manual it states this is important. I've only seen that cause a failure one time, but it can happen.

    Thanks for recording this, I always learn things from someone else's methods!

    That's some quality work right there my friend. Practical and efficient. If I posted a vid like that I'd have everyone questioning why I didn't purge the lines with 141B lol people are crazy.
    Good to see you in action still. Hope all is well.

    Looks like we change oil the same way. This is the best way that keeps the rack running, making the shut down time short as possible. I carry spare float plates in my truck for two reasons. 1. When I changing oil on the rack, we shut down the rack to clean the float plate. I brought a new one and spare gaskets a long time ago. ( I have 3 most common float plates ) so when I shut down the rack, and remove the float plate, I just swap it out with the spare in my truck. Gets rack running in about 15 min. I then inspect the used plate and clean it or buy a new one if the float is damaged. 2. Here is that 2 am call again. If I am on a job where the float plate needs to be changed, or cleaned, again I just swap it and inspect/ clean float plate for the next oil event. I am sure you know what an aggravating job it is to remove the old gasket on an old Temprite 506 or 507 float plate. Always add oil to oil sep to keep the float from getting damaged. I am glad to see you also clean the sight glasses on the oil regulators and compressors. Looks like an old Tyler rack. I have worked for a contractor that services the major supermarkets in Westchester, Putnam, Dutchess counties in New York and also in the rat hole they call the city.
    Very well done video, you are truly a good mechanic. You work neatly and have good experience. I would hire you in a New York minute!
    Be safe

    Another great video! I found your channel when i started working on parallel racks and i learned a lot. Today actually i had bunker case down due to breaker down, i remember your video about short on frame heater-and guess what, my issue was the same! Unfortunately i couldn't find the size for that brass fitting you installed, for crankcase pressure. What size is that? I tried the one i installed on Carlyle, but i think Copeland is different.

    Do you ever have a customer say "hey, why are you making a tv video ON MY TIME??" I wonder how many tech's in the field are wasting company time by making videos to be youtube stars on the company and customer's dime. I have been in HVAC for over 50 years and it seems like every Tom Dick and Harry wants to have their own tv show while they should be WORKING. If I ever have anyone working on anything on my property making a video about it, they either stop or leave now. It could easily add an hour to an hour job. I know some guys will say "hey I'm talking while I'm working", maybe, but your concentration is not 100% on your game and HVACR is dangerous, one of the most dangerous careers in the world, OSHA investigates many injuries and deaths a year and almost all are due to lack of training and/or lack of paying attention. I wonder if any large HVACR companies have rules about it, like text and driving you're fired, tv show while working you're also fired?

    Thank you for making.

    Some places are confusing.
    A diagram of the pipes would be helpful here.
    If a rerun of this could be made that had segways to the diagram when valves are being turned it would be great.

    Thanks, this is a good supplement to other instruction vids.

    These racks are very "valve complicated". When it comes to The Valves — liquid, vapor, oil, whatever — there's always a big glossing over of what's going on, e.g. "we're going to isolate XYZ by shutting off the A B C valves…."

    Problem: the rookie is totally bewildered by that. If he can follow, and knows That Much about rack systems, he doesn't need to watch this video.

    Solution: multiple "cuts" to a diagram that shows the lines being valved — opened, closed, isolated, whatever.

    Onward and…

    Thanks and regards.
