We recommend to change the UV tubes after
1000 – 1500 operating hours as the UV intensity
decreases significantly after that time.
We recommend to change the HEPA Filter after
1500 operating hours (based on the default setting
of 0.5 m/sec of the air flow. With less or more
power, the runtime is extended or shortened, this
will be considered automatically by the runtime
clock), or earlier to avoid clogging.
We recommend to change the Carbon Filter after
3000 h or once a year.

Press the or buttons to change the value to
zero. Press on to store. Press to go

Reaching the maximum of the recommended
operating hours, the UV tubes or filters must be
replaced. Those items will be temporary indicated

hours exceeded). When "duty hours exceeded"
message is displayed, press to reset the
duty hours of the items directly (short cut).
After replacing filters, UV or white light
tubes it is necessary to reset the hours of
