Mitsubishi electric vrf gas recover

[Po65]

Just asking if somebody could help with the way to recover (eg open all the valves from bs box etc ) thanks

Unfortunately with Mitsi Electric there is no easy way to recover as there is no facility to force all of the valves open such as a Code 21 on a Daikin.
It is very important to get a line onto every access port in the condensing unit and recover in the normal way, or you could get gas trapped. Eventually you will get all of the gas out.
Equally important when vaccing out to get on every access port to prevent any OFN being trapped.
