Installation Notes

Impeller is made to fit tight on the shaft. Using a heat gun on high setting heat up the area around the center of the impeller for 60 - 90 seconds. Once heated it will slide onto the shaft without requiring any force. Do not use a open flame tool like a torch as it can overheat and damage the impeller.
