- Thanks to reader NJSnowman for suggesting this clarification, via comments. If left in either the front-seated or back-seated position, heat from brazing can cause the inside plunger to weld to the seating area on the inside of the valve body. (C) is the service line at the gauge center, connected to a refrigerant gas source or perhaps to an evacuator pump. On some larger compressors the process tube may be a smaller-diameter tube used for an auxiliary function such as an ice maker - still charging through that port could be OK. A definitive answer would come from the manufacturer of the specific HVAC compressor motor. Or, it can have fittings soldered or brazed to it to make for easier for future access. 5 With the compressor running, I opened the manifold valve and let the compressor suck in the gas for five seconds or so until the gauge indicated 20 psi. In our illustration of air conditioner service equipment pressure test gauges at page top and at left, you notice that there are two gauges and two sets of connectors and control valves. This allows the refrigerant to flow through the system and the system pressure to be read through the gauge port. With over 54 years of experience, Aaron is the recipient of numerous Super-Service awards from Angies Lists and 2019 Best-of-the City. This compressor comes with a complete kit so you wont have to worry about its installation process. 2. Insert a bullet-piercing valve around the Freon line. To avoid overcharging, its best to charge in short bursts and let the system settle down for a few minutes in between. Your Freon line will attach directly to your tank and feed into the fridge.
