radiometer reading with calibrated radiometer and
AUV/LESCO Quartz Test Fixture.
Verify that the lightguide is properly pushed completely into
the lightguide socket (and that the ball plunger is in the
detent groove if applicable.)
Verify that both ends of the lightguide are clean. (See
section on Lightguides) Clean quartz surfaces with
reagent grade isopropyl alcohol (IPA) using a cotton swab
or equivalent means. If damage cannot be removed,
please send the lightguide back to AUV/LESCO for re-
polishing.
Set the UV intensity to minimum in the front panel. Measure
the UV intensity with regular procedure. Radiometer
measurement through lightguide should be approximately
10% to 20% less than through quartz if lightguide is
standard 5mm x 1M LFLG type without radical bends.
If radiometer measurement through lightguide is
substantially less, replace lightguide (see Lightguides
section of this manual or AUV/LESCO website).
WARNING: Bulbs are extremely hot when first shut off and can cause severe burns!
Disconnect and remove the lamp; inspect the bulb visually.
(
Note:
Do not touch quartz surfaces, particularly if hot.
Fingerprints/body oils will shorten lamp life.) If it is discolored
or cloudy, or has excessive hours, replace the lamp. Insure
correct seating of bulb in reflector housing.
Check the IR filter for scratches, cracks, fingerprints,
solarization or other visual problems. Replace if noted
Check reflector surface quality. Confirm highly reflective
(shiny) surface and correct seating within cradle assembly.
Check reflector for any discoloration (yellowing or blue-ish).
Replace reflector if found.
If intensity is still low after all above checks have been done
and unit has been dropped or jarred prior to low intensity
readings, optical alignment problems may exist. Contact
factory.
Fans Do Not Work
Check for obstructions to the fan blades.
Disconnect the AC power. Remove the top or bottom cover,
depending on which fan is not operating. [
Note
: If the top
fan does not work, disconnect UV lamp before proceeding!]
