• Maintain subsoil temperatures between 35-40 degrees F. Lower than that can result in freezing; higher than that impedes efficiency.

• Track and maintain the fluid levels.

• Perform an annual test on the heat transfer fluid to detect any abnormalities.

• Perform refrigerant checks monthly to detect leaks. • Inspect the pumps, motors and expansion joints weekly.

• Check the inspection pits regularly. (Arenas that have refrigeration pipes should have a pit near the header assembly. Te location and type of these vary by type of refrigeration system. Ask your refrigeration professional where your inspection pits are located.)

• Determine if the components of your underfloor heating system are plastic (PVC) or steel. Are the connections done with hose clamps or fused? Tis answer can indicate possible areas for failure or replacement.

• Maintain a stock of spare parts for your system, including pump couplings, fuses, belts and all other items that may fail on Saturday afternoon at 5 p.m. (that is always when they fail, right?)

• Develop a network of industry contacts who can help you through challenges when a failure happens. After Floyd Hall’s heave developed, I sent photos to several colleagues who all responded with excellent suggestions on how to attack our “mountain.” (Tank you to Chris Geatrakis, Art Sutherland, Jim Hartnett, Bert Blanchette, Bob Koch, Tom Mattioli, Karl Walton, Deniz Yalvak and many others who gave suggestions and offered help. Several came to the arena, sent equipment and cameras and were very helpful with ideas and suggestions based on experience.)

As in all cases with the “back of the house,” you need a plan

and must prioritize inspections, maintenance and repairs of your refrigeration plant to reduce headaches and business interruption down the road.
