Thanks for the tip on using a freon charge and detector. That will be the next step and we'll pump the system down to clear it.
HRD Aero sys in valencia, Ca. hydro tested and leak checked both bottles an the regulator. I also resealed the filler check valve and all six outlets per the manual. I've increased weight with serious efforts insulating the cabin and I'll be weighing the aircraft soon. I hope to still have a decent 4 place zero fuel weight. Thanks again Bob.
