Mechanical Seal
A mechanical shaft seal is used and no adjustment is
required. When the pump operates, the water being
NOTICE
pumped cools and lubricates the shaft seal to prevent it
from overheating.
Prolonged dry pump operation or operating a dry
pump at high speeds will reduce the life of the
mechanical seal.
If the mechanical seal leaks, replace the entire seal.
The same drain (weep hole) is used to vent the mechani-
cal seal on the pump shaft and the oil seal for the bearing
housing. Inspect for water (mechanical seal) or oil (oil
seal) leaks.
Overheat Protection Manager
Check the electrical circuit by pressing the test button
located on the panel plate every 100 hours of pump
operation or every six months, whichever comes first.
If the light does not flash, the light bulb or flasher may
need replacement (provided all wire connections are
solid).
