    What was the outcome? I have multiple stores with various sizes of these things with severel configurations. One thing in common. If its hot inside or in a area, discharge is tripped. With no rhyme or reason. And I'm to logical to believe that.

    I have run into this exact issue. It took a fire hose to get those extra thick coils cleaned out properly and I was amazed at the ammount of dirt that we got out compared to a regular garden hose and pressure washer.
    I would bet a paycheck that your coils are plugged in the center. They may look clean, it's very deceiving.
    How did you get a fire hose hooked up. That is exactly what i need on a job with 3 30 ton condensers
