With pump operating, check for excessive vibration or noise. Vibration is usu-
ally a sign that the impeller is out of balance. Turn off the system, insure
power is shut off and remove the inlet plate. Check the shaft seal and replace
if worn or missing.
With the power off:
Check the inlet and outlet of the pump for blockage or excessive soot and
clean as necessary.
Check boots for cracking or deterioration and replace if necessary.
If a condensate trap is installed, check the condition of the trap and the drain
line attatched. Note: the condensate trap should be filled with water at the
beginning of each heating season.
Check the condition of the motor mounts. Lift the motor from the rear; and
look for breaks in the rubber and replace if necessary.
Check the condition and operation of the pressure switch.
