Question about Refrigerators
I need to know how much r-22 I need to charge my indoor unit adr163a and my outdoor unit tho020dr222 with 15 feet of 7/8 suction line and 3/8 liquid. This is for a walk in cooler.
Can't tell exactly, too many variables, your low side pressure should be about 50 - 60 lbs, ( this is merely a guide ) temperature affects this reading. a simple way to tell is add freon and watch you indoor coil if possible. when the entire coil is sweating you are full. if only partial sweat is visible add more, a little at a time, it takes several minutes for this to circulate.
