The tube is new.
The tube is older than
12,000 operating hours.
If it is a new tube, it is a manufacturing
defect.
With older tubes (> 12,000 operating
hours), the gas composition changes
and ignition can no longer take place.
exchange this tube for
you, free of charge.
The tube service life has been
exceeded; the tube must be
replaced.
The UVpro tube no longer
ignites and shows silver
mirroring or blackening in
the area of the filament.
The service life is still less
than 12,000 hours
Frequent on/off switching causes the
tubes to age faster compared to
continuous operation. With each
ignition, particles are blasted off the
filament, and deposit as an inner layer
on the glass tube.
As a general rule, one ignition consumes
one hour of tube life.
The tube must be exchanged.
The tube life time has been
exceeded, the tube must be
replaced.
The fan has failed or is
vibrating loudly.
The fan is defect or the power
supply to the fan is interrupted.
The fan is covered with dirt/dust.
The device must be
repaired
by
the
manufacturer.
Clean the fan and the light
traps.
The disinfection
effect diminishes and
no longer
corresponds to the
expected
performance.
The tubes have not yet
been in operation for
12,000 hours.
After 12,000 hours of operation,
the UVpro tubes still provide
approx. 75% of their initial
output.
The tubes are dirty.
The fan has failed.
A tube exchange is
necessary.
Clean tubes according to
our cleaning instructions.
The device must be checked
and repaired by the
manufacturer.
When do the UVpro tubes
have to be cleaned?
Dirt (such as dust, grease or soot)
significantly reduces the UVC output.
Regular checking the device and fixed
cleaning intervals are recommended.
The right time depends on the
air purity. In new installations,
inspections should be done
more frequently in the first 2-3
months, to get a feeling for the
intervals.
