    500 microns in 25 minutes

    (2) 3/8 lines straight to the high/low side.
    alot of awesome things were created by impatient a-holes such as myelf.

    YJ wants you to hook your vacuum gauge onto the 1/4" port on the pump.
    I am regularly able to get under 500 within about 20 mins now, after having much trouble, as my pump was sitting in the shop for a year before I got it.
    I flushed out my pump 3-4 times with hot oil and it works fantastic now.

    I like that rig though, I think I will try it.

    IF you hook your gauge at the pump your not reading the pressure in the system. That micron gauge needs to be as far from the pump as you can get it to get the most accurate reading.. Also there is no good way to isolate the system from the pump if you hook it up that way..
    Gotta have the right tool for the job!

    Where is all the stuff MADE IN THE USA?

    Sure there is, close the valve on the pump.
    The ports are upstream of the valve.
    I hook my gauge to the charging port on my brute manifold, then 3/8" to the pump

    To answer 1st question I have 2 of those small hoses with the low loss 90 degree
    Shutoff valve hooked up to the high/low side.
    On those I have a 3/8 to 1/4 reducer, I then hook the 3/8 lines up to those. I am gonna be experimenting with a 3/8 copper tube, 3/8 male on 1 end and a flared on free spinning 1/4 female to connect to unit on there end. I did the math and the volume of air the short low loss hose holds isn't that much smaller than a 3/8, but I'm just curious to try

    You turn the valves closed when reaching your proper vac,
    Unscrew your vacuum hoses and hook up your gauges to the 1/4 tip of the hoses.
    If you want you can then hook up the yellow service hose from your gauges to the pump and pull all the air out of your hoses, and then charge.

    I have my core remove took hooked up to 1 of the ports on the unit that I hook my micrometer gauge to.
    I am not a fun of connecting it to the pump.
    It will read way lower than actual vacuum.

    I have come to the conclusion that otherwise it takes about an hour of vacuum time per ton. I have noticed over the various systems I've worked on, the hr per ton rule of thumb has always been surprisingly accurate.
    The system that was the last straw for me was a 5 ton york that took 5 hrs 15 minutes when I was swamped 1 day and I kept leaving to run other calls while waiting.

    Nice! I recently bought some Appion core removers and it has cut vac time in half. With those core removers, a 7 CFM vac and 4 port gauges I can pull 500 in 30 min or less. I pulled a 350 the other day on a 5 ton unit with a 90' 1 1/8 lineset the other day in 40 min.

    WHat type of hoses are you using on your manifold? Low loss, Ball Valves?

    Standard hoses with valves at the end + the big hose (I forget what size those are)

    Nice setup, charging hoses just dont work well when pulling vacuum, thats the way to go along with an appion core remover with side port for the micron gauge
