Thorough Cleaning
If the unit makes noise during operation, a thorough cleaning of the grid and ionizing wires may be required.
Remove the collection grid by pulling it from the top of the unit.
Wash the grid with warm soapy water, rinse, and allow to dry for 24 hours before returning to unit.
Invert the main housing sev- eral times before replacing the collection grid.
This action will remove any accumulated particles from the ionizing wires.
