Maintenance; Safety Instructions For Repair Work - Orca UVpro V-LAB Operating Instruction

Problem
The UVpro tube will not ignite
and has in the area of filament
silver mirror or blackening.
The life span is still below
12,000 hours.
There is condensation
between the UVC tube and
the cladding tube.
The disinfection performance
decreases and no longer
corresponds to the
calculation.
The operation duration is
under 12,000 hours.
When do the UVpro tubes
need to be cleaned?

Safety instructions for repair work

Make sure there is no current flowing through the device, before starting any work or cleaning process
on the tubes. The UVC tubes should also be turned off during visual inspections.
In the case of a visual control of the UVC-system, do not under any circumstances look at the ignited
tubes without visual protection. Protect your skin through covering clothing, and never touch the tubes
without wearing gloves.

Cause
By frequently switching the tube on
and off it ages faster than in
continuous operation. At each
ignition particles are blasted off from
the filament, which settle as the inner
lining on the glass tube.
As a rule of thumb one hour lifetime
can be calculated per ignition. The
tube must be replaced.
The outer sheath could be damaged.
If no cracks are visible, water must
have entered through the screw joint.
After 12,000 hours, the tubes still
produce about 75 % of the output
power. Designing of facility is
calculated for this value.
The tubes are dirty.
The UVC output drops significantly
when contaminated (e.g.
calcifications or grime. That's why
regular inspections and solid cleaning
intervals are useful and encouraged

Solution
The tube life is exceeded, the
tube must be replaced.
Check the glass for cracks.
Inspect the area of the tube
base for moisture. Dry the
socket and replace the O-
rings.
After commissioning the tube
should be controlled
frequently (daily) for moisture.
The tubes must be replaced.
Clean the tubes by following
our cleaning instructions.
The right time depends on the
water quality. Check a new
installation frequently (2-3
months) to get a feel for the
cleaning intervals.
