CORONA PLATES
Disconnect the power from the unit. Locate the generator head(s) and remove the cover. Each
generator head has up to 6 corona plates. Locate the corona plates. Slide them out of their locating
grooves and clean. All plates must be cleaned at the same time.
Plate Cleaning:
The oxidizer includes a second complete set of corona plates when delivered new. Alternate plate
usage between the two sets. Clean the dirty corona plates by using a dishwasher or hand wash. If
cleaning by hand, begin cleaning the plates by spraying or dipping them in cleaning solution. The
cleaning solution should be a detergent product that is capable of breaking down oils and greases but
leaves no residue when rinsed off. If the plates are rinsed in hard water, then clean compressed air
should be used to dry off of the corona plates to prevent hard water deposits.
CORONA PLATE INSPECTION:
After cleaning, inspect each corona plate for pin holes or other damage. A pin-hole in the plate will
cause the generator head(s) to operate incorrectly. Holes or cracks should not be visible on the plate.
Replace any corona plates that fail inspection.
After the plates have been checked, reinstall the cover.
