How often should I clean my Acuity Brands ELM2LF Emergency Lighting Unit's refractor or lens?

[LaAaron]

Maintaining your Acuity Brands ELM2LF Emergency Lighting Unit's performance requires periodic cleaning of the refractor or lens. The cleaning frequency depends on the environment and the desired light output level. For optimal function, clean the refractor/lens with a solution of warm water and a mild, non-abrasive household detergent. Rinse with clean water and dry thoroughly. If the internal optical assembly becomes dirty, clean the refractor/lens in the same way, replacing any damaged gaskets. Regular maintenance is key to ensuring the unit's longevity and proper operation.
