LED ILLUMINATOR FOR FLAT GLASS GAUGES, HAZARDOUS LOCATION
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
7.3 Troubleshooting
1. Internal or external corrosion could be an
indication of a harsh service environment.

carried out to determine the cause of the
problem. It is the user’s responsibility
to choose a material of construction
compatible with both the contained fluid

7.2 Maintenance procedures
Cleaning the protective glass - wash with a
non-abrasive soap or detergent and water
using a soft, grit-free cloth or sponge. When
cleaning grease and oil from the protective
glass, use a chemical compatible with
silicone rubber only and a soft, grit-free cloth.
DO NOT use solvents such as acetone,
benzene, carbon tetrachloride, dry cleaning
fluid or lacquer thinners since they will attack
the surface of the protective glass and or the
gaskets. After surface has been cleaned and
rinsed of foreign particles, it may be dried with
a clean, soft, damp chamois or grit-free cloth.
IMPORTANT
DO NOT use hard, rough cloths on edge of
protective glass because they can scratch the
surface. The scratches will result in reduced
light output from the illuminator.
6 OPERATION
Check that all installation procedures
have been completed. Use only qualified,
experienced personnel who are familiar with
illuminators and thoroughly understand the
implications of all the instructions. If the
equipment is used in a manner not specified by
the manufacturer, the protection provided by
the equipment may be impaired.
7 MAINTENANCE
The user must create maintenance schedules,
safety manuals, and inspection details for each
specific installation of an illuminator.
7.1 Preventative maintenance
On all installations the following items should
be regularly evaluated by the user for purposes
of maintenance:
1. Protective glass, for signs of dirt build up,
scratches or breakage.
2. Mounting bracket for signs of loosening.
The user must determine upon evaluation of his
or her own operating experience an appropriate
maintenance schedule necessary for his or
her specific application. Realistic maintenance
schedules can only be determined with full
knowledge of the services and application
situation involved.
