Please observe the following (continued)
Vapors of Solvents
Vapors of fluorinated or chlorinated hydrocarbon solvents will corrode the lamp and the quartz
lenses – even in small concentrations. Avoid these solvents in the vicinity of the unit. If you
cannot avoid them, place the unit as high as possible, as vapors are heavier than air.
Explosive Zones
This unit is not meant for operation in explosive zones.
Protection against UV Radiation
To avoid human tissue damage, do not expose the unprotected eye or skin to the ultraviolet
light. For more information on UV radiation see Section 2.2.
Wear UV protective glasses and UV protective gloves!
1.4.2 Special Instructions
Lamp Life Time
Based on an average power-on time of 8 hours per day, the lamp has an expected operating life
time of at least 1,500 hours. Lamp life depends on length of operating intervals, as each ignition
process wears the lamp considerably.
Frequent on/off switching results in premature deterioration of the lamp. Do not switch
off for idle periods of less than 3 hours.
The lamp contains mercury. Do not discard with regular trash.
Dispose of as hazardous waste in accordance with local rules and regulations.
To control the curing process, the UV power output of the system should be monitored on a
regular basis with a radiometer. Use a Zeta
®
7020 Radiometer (available only in North America)
or similar unit.
Lamp Handling
Any contamination, such as fingerprints on the glass, which has not been removed will bake to
the envelope, and result in premature deterioration of performance.
Fingerprints can be removed with a lint-free kerchief and pure alcohol.
The envelope can burst in rare occasions – especially if the lamp is very old. Some reasons
may be etched fingerprints on the envelope, or frequent on/off switching.
Broken lamps will release mercury.
Strategy: Remove every person near the UV Wand System at once to prevent them from
inhaling mercury vapors. The room should be well ventilated (minimum 30 minutes). After
the lamp housing/fragments have cooled, the mercury residue should be collected with
the use of a special absorbing agent available from laboratory equipment suppliers. The
method of mercury disposal must comply with local rules and regulations for disposal of
hazardous materials.
