Inspect the quality of the coolant in the reservoir
Access the coolant in the reservoir via the access cap. System fluid should be clean and free of
contaminants. Test the glycol concentration level to ensure levels are within the rated conditions.
Refill tank as needed with pre-mixed glycol to maintain proper concentration. An inhibited glycol
solution is recommended to prevent algae and bacteria from growing. If low toxicity glycol is desired
or required, use an inhibited propylene glycol.
WARNING
Do not mix brand names or types of glycol as this may result in the inhibitors
precipitating out of solution. Do not use automotive antifreeze in the Chiller Unit
as it can cause extensive damage to the cooling system. The use of automotive
anti-freeze can affect the heat transfer of the system, fluid flow, and attack the
pump seals.
WARNING
Galvanized piping is not recommended because the zinc will react with the
inhibitor in the fluids, causing precipitate formation, depletion of the inhibitor
package, and removal of the protective zinc coating, particularly above 100°F.
Precipitation can also lead to localized corrosion.
7.6.1.5
Inspect fluid system for leaks of loose connections
Visually check fluid connections for any leaks in the system. Ensure there are no plumbing parts that
show any significant wear including chafing or cracking.
7.6.1.6
Inspect and test refrigeration system for leaks
Inspect the inside of the chiller for any visual evidence of refrigeration leaks. Spots of oil on the inside
of the unit or on the refrigeration lines may signify a potential leak. Have a certified refrigeration
technician inspect the unit for proper operation.
