3.1. CLEANING THE DEVICE
Only clean the outside of the device if necessary. Observe the following instructions for external
cleaning:
• Switch off the device and unplug the power plug from the socket.
• Only use a dry or minimally moistened cloth.
• Do not use aggressive or abrasive cleaning agents, since this can damage the surfaces.
• Always make sure that no moisture enters the device.
Due to the prelter and the sterilising technology, neither cleaning nor disinfection should
normally be necessary inside.
3.2. MAINTENANCE INTERVALS
To ensure smooth operation of your device, certain wear parts must be checked at and / or
replaced at regular intervals:
• Depending on the environment, the prelter must be checked at regular intervals. Therefore,
check the degree of saturation of the prelter after approx. 3 months at the latest and
replace the prelter before it is completely saturated.
How quickly the prelter saturates depends among others on the following factors:
- performance level of the air purier
- amount of dust in the environment
- amount of textiles or carpets in the environment
- number of people and animals in a room
- number of air puriers in a room
• If the device is used daily, the high-performance lter (HEPA lter) must be replaced after
approx. one year at the latest. Replace the high performance lter before it is completely
saturated.
• UVC uorescent tubes are subject to natural ageing. If used daily, they must be replaced
after one year at the latest, otherwise the germicidal effect is no longer guaranteed, even if
the UVC uorescent tubes are still visibly illuminated.
• For all maintenance work, it is recommended that you wear work gloves and a face mask for
self-protection.
