General Pump Controller Maintenance
When properly installed, and with routine inspection and
maintenance, the pump panel control can be expected to be
trouble free during the entire operating life of the pump.

dust and debris which may have accumulated.
2. Check all screws for tightness.
3. Check to verify that the normally closed contacts open when
the overload relay’s test trip button is depressed. Reset the relay.

Class 87 Pump Panel Contactor Maintenance
1. Periodically examine the contacts – cleaning is not required
since the contact material is a special pre-oxidized silver
cadmium oxide alloy. Replacement is required only when
the contact material is almost worn down to the backing.
A complete pole consists of stationary and movable contacts
and a contact spring. This feature ensures proper contact
mating which, in turn provides maximum life.
2. Check magnet poles for foreign deposits and if present, carefully
clean pole faces with solvent.
