4.16. UV Light Tube Replacement
4.16.1. The expected life of the UV light tube is nine (9) months to one (1) year
depending on the environment and prefilter maintenance schedule.
4.16.2. Remove the five (5) screws on the left hand UV containment baffle or the five
(5) screws on the right hand containment baffle and remove the baffle
assembly.
4.16.3. Reach around the UV light assembly, taking care not to touch the face of the
HEPA filter, and grasp the "old" light tube gently. Rotate the light tube 90
degrees in either direction to enable removal (you should feel tension on the
tube release). To remove the light tube, carefully pull away from the UV lamp
assembly, towards the HEPA filter. Dispose of the light tube (or recycle)
following local guidelines.
CAUTION: Touching the face of the filter could cause damage to the filter media
resulting in the need of professional repair or replacement.
4.16.4. Use Clean latex gloves to ensure that the new light tube remains clean. Clean
the new light tube using a cloth dampened with a 10% alcohol (or ammonia)
and water solution. To replace, reverse the order of removal.
