SERVICING / WARRANTY LEHL2
Servicing
- To avoid personal injury, disconnect power to the light and allow the unit to cool down before performing maintenance.
- Perform visual, electrical, and mechanical inspections on a regular basis. The environment and frequency of use will determine
how often. However, it is recommended that inspections occur annually.
- The external lens should be cleaned periodically to ensure continued luminaire performance. Clean the lens with a clean, damp,
non-abrasive, lint-free cloth. If this is not sufficient, use a mild soap or a liquid cleaner. Do not use an abrasive, strong alkaline or
acid cleaner as damage may occur.
- Inspect the cooling fins of the luminaire to ensure that they are free of any contamination (i.e. excessive dust build-up). Clean
with a non-abrasive cloth if needed.
- Check all moving parts and components to ensure they are properly assembled and in good operating order.
- Check all electrical connections to ensure all connections are clean and tight.
