*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.
