Perform Planned Maintenance on Ice Machines
Maximo: 62999, trailer 184. Arrived 2-19 to replace compressor per Allen‘s authorization. Started by recovering the charge, the weight was in accordance with data plate and didn’t appear to be below the recommended weight charge. I also replaced the filter drier. Pulled vacuum on unit yesterday but was forced to stop due to rain. Charged with 300 psig nitrogen and let stand overnight to help eliminate moisture and pressure test. Returned 2-20 and nitrogen held overnight with 0 psig drop. pulled unit down to 400 microns and ran a decay test. U it passed. Charged with 6 lbs 12 oz virgin r410a. Energized unit and compressor started in heat mode. After 5 minutes the unit was supplying 100° f at the supplies. Tested defrost mode and tested emergency heat. Unit cycled off with thermostat at 70°. At this time it appears all components working normally and no further issues at this time.
