Replacing UV LED lamps (on the front and rear of the unit)
Both UV LED lamps of the Clean Air Optima CA-509Pro Smart air purifier have a service life of
8,000 operating hours = 1 year of 24/7 operation. The UV LED lamps should be replaced after
8,000 hours of operation, or if the indicator light (UV) on the display goes out.
1. Switch off the device and pull the plug out of the socket.
2. Press the release buttons with both fingers and remove the front and rear covers.
3. Remove the filters (front and rear).
4. Use a Philips-head screwdriver and remove the screws from the metal guard of both UV LED
lamps (front and rear).
5. Pull the power cord out of the housing towards you until you see the plug connectors.
Unlock the plug connectors, see figure.
6. You can now fit the new UV LED lamps. After the UV LED lamps have been fitted, the
indicator light (UV) will light up again.
