Hhi folks .
could anyone tell me the best port on The outdoor unit of a dakin vrv three pipe to purge from.
I have. My refnet in to feed the extra bs box and my unit is hung up and piped . I plan to vent my purge of nitrogen via. The other ports on. The out door to eliminate. Those pesky pin holes .
i take it that. The bs box valves are open. Till power. Is applied ?
