Where each walk sits in the schedule
- Chiller quarterly maintenance checklistquarterly
- Every quarter, with readings taken under load so the numbers mean something, not at standby. Run by: The chiller service tech on the contracted quarterly visit.
- Chiller annual maintenance checklistannual
- Once a year, scheduled in the off-season so the machine can be opened, tested and down without load impact. Run by: The chiller manufacturer's or specialist service technician.
What most often fails on a chiller
- Readings logged from the display without comparing them to what the sensors should be saying.
- Approach temperatures creeping up quarter over quarter with no one trending the log.
- Refrigerant sight glass checked for presence of flow, not for moisture indication.
- Tubes punched without an eddy-current or condition record, so pitting is discovered as a leak.
- Oil analysis skipped because the oil 'looked clean.' The lab catches what the eye can't.
- Safety trip setpoints drift-checked on paper but never actually tripped during the test.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.
