Review on AURELIO TECH Manifold Refrigerants Adjustable by Noel Pilla

I liked the metal handles and 4 connection points, I just installed a mini split system and connected it to a two stage vacuum pump to evacuate the system and everything worked fine. Note that most instructions for mini-splits assume you have a 3-way splitter installed (you don't want to cover the blue button on this set. For this setup, connect the blue (bottom) side of the gauge to an external mini service unit. Then connect the black vacuum connector from the gauge to your vacuum pump and then open the blue and black knobs. Then run it for a good 15-30 minutes to lower the line to drain the system. Turn on just plug the black vacuum button then the vacuum pump and leave it on for as long as possible, I left mine for 30 minutes while I wired the outdoor unit If it holds a vacuum then your first leak test went well Overall a good set for the price and now I will be using this kit to charge my SUV.
