Specifications include, but are not limited to: rane Centrifugal Chillers Comprehensive Annual Inspection Service 1. Report in with RIAC. 2. Record and report abnormal conditions, measurements taken, etc. 3. Review report logs with RIAC for operational problems and trends. General Assembly 1. Check and record refrigerant level. 2. Inspect for leaks if required and report leak results. 3. The refrigerant should be correct before starting the leak check. To prevent unnecessary venting of refrigerant, EPA-recommended methods (e.g. hot water and/or electric blankets) must be used to pressurize the vessels. 4. In order to use EPA-recommended methods, certain conditions must be met: i. The isolation valves on the chilled water and condenser water lines must shut off the circulation completely. ii. The temperature of the equipment room should be 70F or higher. iii. Access connections to the condenser water and chilled water (RIAC’s responsibility). If these conditions cannot be met, the refrigerant must be removed and the vessel pressurized, using dry nitrogen and a trace gas. 5. Repair minor leaks as required (e.g., valve packing, flare nuts). 6. Visually inspect condenser tubes for cleanliness. 7. Check vanes for free and smooth operation.
