NOTE

Maintenance procedures sometime require fixtures to be hosed down for good house-
keeping.  The circuit must be turned OFF and fixture globe MUST be allowed to cool to
ambient room temperature before cleaning.

The fixture should be cleaned periodically to maintain maximum light output.  Only

mild, non-abrasive cleaning agents should be used.  The dome should be regularly inspected for
scratches and chips, and if damaged, must be replaced.
