Cleaning Plates
IMPORTANT: Ensure the unit and plates are fully cooled before maintenance.
• Make sure the unit is off and unplugged.
• Remove screws from the side of the unit and air vent.
• Unit will have 6 screws.
• Place the screws in a safe location so they aren’t lost during the maintenance process.
• Remove the outside cover.
• Use a razor blade to scrape oxidized materials from the plates.
• We recommend using a at, straight razor blade for best results.
• Be sure to not hit where the plates are soldered together.
• If the solder is fractured, the plate will need to be replaced.
• Scrape across the grid lines on the plate.
• Be sure to scrape the plate evenly.
• Clean oxidized materials from the razor blade as needed.
• Repeat this process unit the metallic nish of the plate returns.
• Use a paper towel or blow across the plates to remove oxidized material that could be left
behind.
• Replace the outside cover to the unit.
• Place screws back into the unit.
• Connect the power cord to test that the unit is still working properly.
• There should be a purple glow coming off the ozone plate.
• Cleaning the plate will limit spotting and should emit a steady purple glow.
Cleaning the A7K plates regularly will extend the life of the ozone plates.
