Responsibility
- It is the responsibility of maintenance personnel at McNeese State University to carry out routine, scheduled, preventive, and emergency maintenance on chillers, boilers, heating, ventilation and air conditioning systems.
General Guidelines
- Chillers
- Actions essential for the proper and efficient operation of chillers should address the following items:
- Checking for leaks and proper purge system operation.
- Brushing condenser tubes of water-cooled open tower systems.
- Checking condition levels of refrigerant and oil.
- Checking chiller safety devices.
- Actions essential for the proper and efficient operation of chillers should address the following items:
- Heating, Ventilation, and Air Conditioning System Maintenance (HVAC)
- To ensure that HVAC systems work at peak efficiency, maintenance personnel should:
- Maintain building temperatures within recommended guidelines.
- Check, adjust, calibrate, and repair all controls such as thermostats, controllers, valve and damper operators.
- Replace dirty filters and keep economizer dampers clean.
- Keep all heating and cooling coils clean.
- Eliminate duct work leaks at joints and flexible connections.
- Keep ducts adequately insulated.
- Repair or replace defective dampers.
- Check, adjust, or replace fan belts.
- Lubricate all bearings and other friction joints.
- Inspect fan wheels and blades for dirt accumulation and clean them as required.
- Adjust or repair packing glands and seals on valve stems and pumps.
- To ensure that HVAC systems work at peak efficiency, maintenance personnel should:
- Boilers
- Maintenance personnel should:
- Continuously survey the steam system to identify and repair all steam leaks.
- Use acoustic or temperature probes to find non-visible leaks.
- Perform frequent boiler tune-ups.
- Inspect and repair steam traps periodically.
- Inspect insulation on pipes and pressure vessels periodically.
- Periodic inspection of condensate system.
- Repair or replace worn or damaged insulation, tanks, valves, strainers, and piping.
- Maintenance personnel should:
- Testing
- Test procedures are according to manufacturer’s recommendations and suggested schedules.
- Documentation of testing is kept in the HVAC Department.
- Testing should be of a non-destructive nature and may included, but are not limited to, the following approved methods:
