1.5 Special Instructions
Lamp Life
Based on an average power-on time of 8 hours per day and normal service conditions,
the lamp has an expected service life of
– Fe-doped
700 hours,
– Pure mercury vapour 1000 hours (standard lamp), and
– Gallium doped 600 hours.
The life time of the bulbs is valid only at the operating condition of 1000 W. They will be
much shorter at 500 W.
To prevent excessive wear of the bulb when operating at 500W, the bulb must be
operated at 1000 W daily for about 15 minutes.
☞
Note!
At 500 W the spectrum of the Fe-doped bulb is reduced to the spectrum of the Pure
mercury vapour bulb!
All bulbs contain mercury. Other dopings are available for special applications.
UV bulb intensity deteriorates gradually with time. Bulb life depends very much on length
of operating intervals, as each ignition process subjects the bulb to considerable wear.
☞
Note!
Frequent on/off switching results in premature deterioration of the bulb. Do not switch off
for idle periods of less than 3 hours.
How to Handle the Bulb
Any contamination which has not been removed, such as fingerprints on the glass, will
bake to the envelope and result in premature deterioration of performance.
☞
Note!
Fingerprints can be removed with a lint free wipe and
pure
alcohol. Before reassembling
the bulb into the unit the alcohol must have evaporated completely!
In rare cases the envelope may burst – especially if the bulb is very old. The reasons
could be etched fingerprints on the envelope or too frequent on/off switching.
WARNING!
Broken bulbs will release mercury.
Proceed as follows:
Remove all persons at once from the immediate vicinity of the UVALOC System to prevent
breathing of mercury vapours. The room should be thoroughly ventilated (15 – 20 minutes).
When the unit has cooled down, mercury residues should be removed using absorption
systems available from specialty chemicals suppliers.
Overheating
If the maximum operating temperature is exceeded the bulb is automatically switched off
and the shutter closes automatically. After the unit has cooled off sufficiently
(
≤ 55 °C in the lamp housing) the lamp can be ignited again. Overheating may be caused
by obstruction of ventilation slots or excessively high ambient temperatures.
Repair and Servicing
Always disconnect power cord before opening the unit.
Before servicing, always let the unit cool down for 5 minutes. Do not attempt any repairs
except exchanging the bulb and filter mat, see section 8.3 and 8.4. Refer all other repairs
to an authorized Henkel service center.
WARNING!
High voltages are present inside the unit!
