Cleaning the LED Head
**WARNING**
Do not attempt to open the enclosure of the LED head. Ensure power to the power
supply unit is OFF and the UV LED arrays are cool before attempting any cleaning
procedure.
Use protective gloves or finger cots suitable for the cleaning solution selected. Refer to the MSDS for
guidance.
Turn off the UV LED head and keep the optical window, face down to prevent the solvent from seeping into
the window during the cleaning procedure.

solvent as indicated in the cleaning materials section.

Before using any solvent, consult the manufacturer's Materials Safety Data
Sheets (MSDS) and your internal Health and Safety Advisor for proper handling
and storage.
Using a new saturated tissue; clean optical window by gently wiping the surface with a continuous stroke in
one direction.
Note:
Never apply a dirty tissue or swab to the optical window of the UV LED Head.
Note:
Never face the optical window upwards before the solvent has evaporated.
