019062F 602347 Raypak® Avia Unitherm Governor Kit Regulates Water Temperature At 120°F And Protects Avia 264–404 Pool Heaters From Overheating
The 019062F 602347 Raypak® Avia Unitherm Governor Kit is a critical OEM replacement component engineered for Raypak Avia pool and spa heaters ranging from 264,000 to 404,000 BTU. This component is designed to regulate internal water temperature to approximately 120 degrees Fahrenheit, ensuring controlled heater warm-up and protecting the heat exchanger from thermal stress.
The Unitherm Governor functions by restricting water flow through the heat exchanger until the internal water temperature reaches approximately 120°F. This process prevents cold water from entering a hot heat exchanger during startup or low-flow conditions, significantly reducing the risk of thermal shock, scale formation, and premature heat exchanger failure. Once proper temperature is achieved, the governor allows normal water flow for efficient heater operation.
A failed or restricted Unitherm Governor may result in overheating faults, erratic water temperatures, frequent cycling, reduced heating efficiency, or heater shutdowns caused by excessive internal temperatures. Replacing the faulty component with the genuine 019062F 602347 Raypak® Unitherm Governor Kit restores proper hydraulic balance, temperature regulation, and long-term heater reliability.
This Unitherm Governor Kit is manufactured to exact factory specifications and is intended exclusively for Raypak Avia series heaters rated between 264,000 and 404,000 BTU. It is not compatible with other Raypak heater families or legacy models.
