Troubleshooting:
The device itself emits an unpleasant odor:
A new air purifier still has a slight smell of its own (fresh plastic, new engine, new paint etc.). This new smell
evaporates within shortest time (1-2 weeks) !
The air sensor causes problems:
Please read the notes under point 6 (Air Sensor Operation / Auto Mode). If the explanations listed there do not
apply and the air sensor continues to cause problems (despite cleaning and/or adjustment), read the following
notes:
1. Check that the unit is in night mode. If yes, make sure that the control panel and the integrated light sensor
receive sufficient light.
2. Have you left the air purifier in "Auto mode" times 12 hours "free hand" or have you let it run in continuous
operation ? Especially at the beginning and especially with smokers, 12 hours of continuous operation and
more are quite normal, because often particles/odor patterns sit in the whole inventory (curtains, cushions,
carpet etc.) and depending on the nature of the material, it can take considerable time, until this inventory gives
off the odors again.
3. Please make sure that the air sensor function is not used when the air purifier is in a draught (e.g. between two
open windows and/or doors).
4. In very rare cases, the air sensor may react negatively to certain substances (e.g. furniture polish, perfume,
etc.) in your room. In these cases you should refrain from using the automatic air sensor operation (Auto
Mode).
It takes too long for smoke and/or odours to be neutralised:
In general, our air purifier is very well suited for odour and smoke neutralization. However, please note that the
result of our air purifier always depends on how many odour particles flow in and how the air circulation in your
area is !
This is because the odour filters inlay absorb/remove only a part of all odour particles in a single pass. For this
reason, three filter passages are given until all odour particles are absorbed.
(Note: When filtering dust and particles, one filter pass is sufficient to clean the air, as all particles are retained in
the fine filter = 99% effectiveness. For odours the carbon & catalyst filter is mainly used and here the filter medium
needs approx. three filter passages per sqm³ of air until one can speak of clean air = 33% effectiveness !!)
Furthermore it is to be considered also that smell patterns can already sit in the inventory (furniture) - and
depending upon condition of the individual materials, it can take substantial time, until these have delivered the
smells again.
(The air purifier WDH-AP1101 only eliminates odours that are circulated or filtered by it.)
The device does not respond / The device cannot be switched on:
1. Check that all filters are properly inserted and that the front filter screen is properly closed.
2. Check whether the filter change indicator lights up. If so, replace/clean the filters and then press the remaining
button (see point 7 of the instruction manual).
