i have a R22 system and the outside condensing unit has 2 fans 1 allways runs and the other is operated by a (fan pressure switch) its getting up to 260 psi on the condenser discharge.
My question is at what pressure should a FPS (fan pressure swith) kick in at to turn on the second fan? i didnt have time to test the switch yet but it would be really nice to know exactly when to expect in to come on...... ?????
