Hey Guys
Need to recover refrigerant charge on a water cooled chiller..Pumps can not be turned on to circulate water through the chiller while am recovering
What is the safest way or method to recover refrigerant charge with out freezing up any tubes when recovering refrigerant when there's no water circulating through the chiller.Can the push and pull method be applied to recover?

-Thanks

if there is no water in evaporator then you can recover as normal
