Mini split uninstall / refrigerant recovery

[max_well]

Hey
I'm hoping to get some advice on the protocol for pumping the refrigerant back into the outdoor portion of a Fujitsu mini split in order to safely uninstall for relocation.
What's the best order of operations and timing for closing the lineset valves and turning the unit on /off? hoping to do this without a tech if possible.
Any thoughts are much appreciated!

It's called Pumping Down and can be done with nothing more than a gauge set.

If you have the manual for it the instructions should be in it. If not, type the make and model into google and you should find a manual for it there. I pumped down the freon in the Mitsubishi I had and it was very easy to do. Has been a while and I can't remember which valve it was I closed first, ran it for a minute and closed the second valve then turned the unit off and disconnected it. Reinstalled, vacuum pumped the lineset down, opened the valves and it was good to go.

1 Hook up you gauges and purge
2 close liquid line service valve "small one"
3 Put service wrench in the suction line service valve
4 engage the contractor in cooling mode with an insulated tool.
5 run compressor until desired vacuum is achieved
6 close suction service valve
7 release the contractor or shut of the disconnect.
