📋 Certified SOP
Engineering Maintenance Protocol
- Calibrate cut-in and differential cut-out settings on KP1/KP5 switches with deadweight tester
- Inspect sight glass for moisture indication (Green = Dry, Yellow = Wet)
- Measure evaporator superheat at TXV sensing bulb location (Target: 6 - 8 K)
- Replace filter drier during every compressor opening or refrigeration evacuation
