Hi Guys,

Sorry, I have been reading through the forums and found loads of interesting stuff My lastest thoughts are towards triple evacuation on split ac/heatpump systems? All of the text I have read states triple evac takes place on the plant low and high side valves, but split systems like daikin only have a service valve on the gas side, so is a triple evac really necessary? Is the standard, from what I have seen, chuck you vac pump on, leave it for as long as you can method really suitable? Of course these guys strength and leak test first

many thanks,

B
