Some sporadic crackling in the hood is normal. It indicates that air is cleaned by the ionizer. When
crackling continues persistently, the upper metal filters and the ionize sheet must be cleaned.
Furthermore you should check if the connector of the supply cable is connected to the ionizer sheet
In case of undervoltage it can happen in power step 1 that the interconnecting relay for the ionizer and
for the UVC lamp switches on and off several times (flips). You can eliminate this by shortly activating
power step 3.
Hood cannot be switched on:
Check if all filters are inserted correctly, since each filter is provided with a microswitch, which interrupt
the circuit in the hood if any of the filters is not correctly in place.
