Sacrificial Anode
A zinc sacrificial anode is in place on all models on the
pump housing. The purpose of these anodes is to prevent
corrosion of metal parts due to electrolysis. The mounting
surfaces must be clean and the mounting bolt tight to main-
tain a good connection between the pump and anode.
1. Periodically inspect anode for excessive wear.
2. Check bolt to be sure it is tight. If the bolt is loose,
remove anode and clean mounting surfaces on pump
and anode.
3. Apply dielectric grease to bolt threads and contact
surfaces.
4. T ighten bolt securely.
NOTE: Replace sacrificial anode whenever surface erosion is present, or whenever anode looses con-
tact with mounting bolt.
W ARNING: Once anode loses contact with mounting bolt, severe corrosion of the pump assembly will occur.
