Recirculating Chiller Inspection and Recertification Checklist
- Inspect display for dimming or dead pixels and replace as necessary to maintain clear visual feedback
- Verify functionality of all buttons and input devices, ensuring reliable and responsive control
- Check that all external hosing connections are secure and properly installed to prevent leakage
- Test unit flow rate on a closed-loop system to confirm consistent fluid dynamics
- Examine all external surfaces for leaks, confirming a sealed and contained system
- Inspect internal components for any signs of leaks to ensure system integrity
- Verify power supply output for accurate voltage delivery per operational specifications
- Inspect all internal wiring, checking for any frays, tears, or compromised insulation
- Replace internal filters to maintain optimal fluid purity and system performance
- Confirm that the fan operates at proper speeds to provide effective cooling
- Verify compressor functionality for consistent performance and cooling efficiency
- Test cooling capacity, confirming it meets performance specifications at 20°C
