Maintenance Tips
- Keep the equipment bay dry and well-ventilated to protect the sealed Laing ECM motor from moisture damage and corrosion.
- Clean or replace filters regularly—restricted flow can strain the circulation pump and reduce efficiency.
- Ensure the pump is never run dry; always maintain proper water level to protect the shaftless, seal-less design.
- Inspect inlet/outlet unions and plumbing connections for small leaks or air intake that can reduce circulation performance.
- Check for unusual noise, vibration, or intermittent cycling, which can indicate early pump or control issues.
- Maintain balanced water chemistry to prevent scale buildup that can reduce flow and efficiency over time.
- Verify stable voltage supply to avoid stress on the electronically commutated motor and extend lifespan.
