Had this medium temp rack with a blown compressor #1. Valves were smashed. Found in low extreme low ambient conditions the condenser is oversized. Typically I don’t like to shut off all fans to avoid “shocking” the condenser coil. So we installed isolation valves to restrict flow through half the condenser. Problem solved. Would have liked to see a headmaster installed but price was a factor on this one.
