Tightening Impeller
Periodically check the impeller to make sure it is
tight on the motor shaft. Any unusual vibration or
noise may be an indication that the impeller has
loosened. A set screw and a left-hand cap screw
secure the impeller to the shaft. These can be
accessed through the inlet cover, as shown in
Figure 23. Tighten the fasteners as needed.
