Absorption Chiller Annual Service Report

Annual inspection and service record for absorption chillers, documenting lithium bromide solution condition, octyl alcohol level, generator pressure, purge pump operation, safety devices, and service deficiencies.

Inspection Details and Equipment Identification

• Asset identification matches equipment nameplate and site record
  Record chiller make, model, serial number, asset tag, and location.
• Service date, technician, and work order number recorded
  Enter the annual service date, inspector name, and work order or service ticket number.
• Unit was in a safe condition for inspection
  Verify the unit was accessible and the area was free of immediate hazards before service began.

Operating Conditions and Solution Chemistry

• Lithium bromide concentration within OEM specification
  Measure and record the lithium bromide concentration for the solution circuit.
• Octyl alcohol level within acceptable operating range
  Record the octyl alcohol level or charge condition per OEM guidance.
• Generator pressure recorded and within specification
  Measure generator pressure and compare against the manufacturer specification for the operating condition.
• Solution appearance free of abnormal discoloration, crystallization, or contamination
  Inspect the solution condition for signs of contamination, crystallization, or other abnormal appearance.

Purge System and Vacuum Integrity

• Purge pump operates normally during service check
  Verify purge pump starts, runs, and cycles as expected with no abnormal noise, vibration, or leakage.
• Purge system shows no active air ingress or vacuum loss indicators
  Check for evidence of air ingress, vacuum degradation, or purge alarms during the inspection.
• Purge piping, valves, and connections are free of leaks
  Inspect visible purge system components for leakage, corrosion, or loose fittings.

Mechanical Condition and Safety Devices

• Refrigerant and solution pumps operate without abnormal noise or vibration
  Observe pump operation during the service check and note any unusual sound, vibration, or overheating.
• Safety controls and interlocks function as intended
  Verify applicable safeties, shutdowns, and interlocks respond properly per OEM procedure.
• Pressure relief devices and visible safety components show no damage or tampering
  Inspect relief devices, guards, and related safety components for damage, corrosion, missing seals, or tampering.

Electrical, Controls, and Housekeeping

• Electrical panels and controls are secure and free of obvious damage
  Verify covers are in place, indicators are legible, and there is no visible damage or overheating.
• Area around the chiller is clean, accessible, and free of obstructions
  Confirm access to service points, panels, and emergency shutoff paths is unobstructed.
• Service deficiencies and corrective actions documented
  List all deficiencies, non-conformances, repairs completed, and follow-up actions required.

Final Verification and Sign-Off

• All critical deficiencies communicated to responsible party
  Confirm any critical findings were reported to the site contact or supervisor before closing the job.
• Inspection completed in accordance with OEM service procedure and applicable safety practices
  Confirm the annual service followed the manufacturer procedure and safe work practices, including lockout-tagout where applicable under OSHA 1910.147.
• Inspector signature
  Technician or inspector signs to certify the annual service record.
