Servicing
To avoid personal injury, disconnect power to the fixture and allow it to cool down before performing maintenance.
Perform visual, electrical, and mechanical inspections on a regular basis. The environment and frequency of
use should determine this. However, it is recommended that checks should be made at least once a year.
The external glass should be cleaned periodically to ensure continued performance. Clean the glass 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 on the fixture to ensure that they are free of any contamination (i.e. excessive dust
build-up). Clean with a non-abrasive cloth if needed. Mechanically check to make sure all parts are properly
assembled.
Electrically check to make sure that all connections are clean and tight.
