    Let me guess,......You are going motor master (ICM) control??? yes? Will you change your sleeve bearing cond. fan to ball bearing so it don't prematurely burn out? more than 1 way to skin a cat, but will the customer pay for the repair.....:-)

    Lets say that this is another way to go, so, what is the pressure that the "motor master" is set for? But then a "motor master"is not allowed in this situation. Just another "Compressor Killer".

    I always liked the headmaster with a flooded condenser.

    I’ve used ICM’s in the past with no problems. Penn P-66 is another option. Headmaster is the way to go but they can get real expensive to retrofit.

    Any comp operating at 0* evap temp or lower requirers "air impingement" on the comp body to cool off the comp motor.So cond fan cycling and motormaster are not allowed.
