Lamp Removal; Lamp Cleaning Procedure - Industrial Scientific VX500 Instruction Manual

Industrial Scientific Corporation recommends an abrasive
lamp cleaning, which will restore the lamp's window to a
pristine condition. A lamp cleaning kit is available (part
number 17090721). Because the output of a freshly
cleaned lamp is not fully stable until after a 24 hour burn-
in, please use a VX500, or one of the built in lamp
conditioners contained in an Industrial Scientific charger
or Docking Station™ to burn-in the lamp. If the unit is
calibrated with a freshly cleaned lamp, sensitivity of the
detector will gradually decrease until the lamp's output
stabilizes. This should occur within 24 hours.

To remove the lamp from the VX500, unthread the unit's
lamp cap (cap is a right hand thread). After removing the
lamp cap, grasp the bulb's tubing grip, and pull the lamp
straight out of its compartment. Inspect the lamp's
window for dirt, debris or oil residue. DO NOT TOUCH
THE LAMP'S WINDOW !!!

To clean the lamp, grasp the lamp by its body, not its
tubing grip. Place a grey abrasive pad from cleaning kit
17090721 on a flat surface. (The adhesive on the back of
the gray abrasive pad may be exposed via removal of its
protective covering to affix the pad if desired). Position
the UV lamp on the abrasive surface of the pad so that the
window is flat against the surface of the abrasive pad.
Apply light pressure to the lamp. Turn the lamp and lift.
Reseat the lamp in a fresh position on the pad, and repeat
this process 10-12 times to fully clean the lamp.
To remove any abrasive residue from the lamp, grasp the
lamp by its body again. Please use the brown felt cleaning
pad from cleaning kit 17090721 on a flat surface, exactly
like the abrasive pad. The adhesive on the back of the

brown cleaning pad may also be exposed via removal of
its protective covering to affix the pad also if desired. As
with the abrasive pad, position the UV lamp on the felt
surface of the pad and make sure it is flat. Apply light
pressure to the lamp and turn. Lift the lamp from the pad
and reseat in a fresh position. Repeat this process 5-6
times.
The lamp should be burned-in for a 24 hour period after
cleaning. The VX500 should then be recalibrated once the
lamp is re-installed in the unit. During lamp installation,
insure that the lamp is fully seated in the VX500.
