**WARNING: The Hydraulic conditions or water chemistry that caused the tube bundle to fail have very likely also damaged the bypass valve and Unitherm Governor. We recommend you replace the Unitherm Governor and inspect the bypass assembly. Failure to do so could cause premature failure of this replacement part.

***WARNING: Copper and Cupro Nickel heat exchangers and tube bundles are not interchangeable. Units with suffix "C" must use copper replacement parts and units with suffix "X" must use cupro nickel replacement parts.
