9. Troubleshooting
The air purifier will not switch on
• Check the voltage/power supply or whether the mains socket (e.g. of a socket strip) is turned on.
Insufficient air volume during operation
• Check the filter, clean or replace it if necessary. Clean the air inlets of the air purifier, as described in section 8. b).
• Choose a higher fan speed.
Poor cleaning performance
• The air purifier is suitable for premises up to 30 sq.m.
• Dust exposure is too high. The air purifier is only intended for premises with normal dust exposure (e.g. living
rooms), but not for premises with working machinery (e.g. grinding machines) or similar equipment.
• Check the filter, clean or replace it if necessary. Clean the air inlets of the air purifier, as described in section 8. b).
UV-C emitter does not work
• Replace the UV-C emitter with a new one. Make sure you use the UV-C emitter with identical rating (same type,
same configuration, same electrical and optical data).
• The filter is installed incorrectly or there is no filter in the air purifier. The air purifier has a safety switch. The UV-C
emitter can only be enabled if the filter has been inserted correctly. The safety switch is operated via the filter ring.
Attention!
Never attempt to operate the safety switch with any other items, bypass it or otherwise hinder its function.
Otherwise, this may result in uncontrolled UV-C radiation exposure. This, in turn, may cause damage to the
eyes and skin!
The fan does not turn or generates abnormal noises
• The filter is blocked or its functionality is impaired (e.g. due to an object that has fallen onto the air purifier). Dis-
continue use of the product or turn it off and disconnect from the mains supply. Have it checked by a specialist.
The air purifier emits a continuous beep
• Discontinue use of the product or turn it off and disconnect from the mains supply. Have it checked by a specialist.
