Arrived at location on 6/28/22 - unit is solid block of ice. Joe will empty tonight and we will return tomorrow morning after 9am. Returned to location on 6/29/22 - Unit was unplugged and had no ice. Hooked Gauges up and checked pressures and it was running high head pressures. Suspecting noncondensable in system cause dirty coil. Removed charge and vacuumed system down to 500microns. Recharged unit with 2lbs of 404a. System is now working properly.
