    You don't need to open the system so you don't need the vacuum pump at all?

    If the system has valves and ports in the right locations....
    use a recovery machine to pump the condenser into the receiver, stop at about 2 psi. Braze the leak. Open the valves. Top up the system. Hand them a bill.

    No vacuum pump needed, and down time of less than an hour.

    I've fixed leaky condensers a few times like this, and evaps dozens of times (those are really easy since you can use the compressor to pump down.

    Let them know to keep the door closed, isolate it, pull the charge, braze it up, quick vacuum and let 'et rip.

    I like to have everything laid out, hooked up, ready to roll before I start. Manifolds and recovery machine hooked up, vacuum pump hoses ready, everything ready to roll
    I use a box, tub, or bag filled with ice and surround the the recovery jug with ice to take away the heat of the recovery process. Seems to nearly double the speed of refrigerant recovery.

    If you're that worried about moisture, stick a new drier in it, too.

    Yeah, i just read it again..condenser return bend...then the 4 hour prediction would be right.
    Every customer you take for granted today will be someone else's tomorrow.

    Take all the time you need. All that frozen food would take a loooooooooooong time to thaw out, probably a few days.

    Timber is right, it takes a long time to thaw. Main thing as others the stated " keep the door closed". I've shut freezers down for 2 hours at a crack with people in and out of door without a problem.

    I would repair the leak. As previously stated, I doubt it will take long enough to lose product. Even if it does, product was going to be lost when it went down again anyway. Just don't eat anything from that freezer.

    I had a walk in freezer go down at 9 pm once, the customer did not want to pay overtime to repair it. I returned at 7 am the next morning and it had warmed to 9*F. By the time the repair and proper evacuation were done, the box was at 21*F. Over 12 hours down, with the door closed, no lost product.

    It's a small leak or it's got one big receiver

    Really?

    I don't know that I would agree with this - but obviously it has worked for you in the past.
