I would briefer reclaiming the refrigerant to pump down. i know it is a long method comparing to pump down but it is reliable and time saving in the cases of service valve passing
thanks mate,but i do not need to add any refrigerant, it is not the master unit.

hi , can you not get someone in to do a propper job? if you havent got the confidence or the experiance , how are you going to do the job properly?
thanks for your advise, very helpful
ok in some units there is a proceedure in which automatically ref will be parked and then you front seat vales, rather than lp switch and manual pump down. that was the question?

The system should be fully recovered. No VRV 3 system can be pumped down without risk of damage to the compressors. Set "Refrigerant Recovery Mode". Mode binary 21 to open all valves within indoor and outdoor unit and leave power on until fully recovered.
