Installation, Operation & Maintenance Manual
MAINTENANCE
Examine the gauge glass regularly for any signs of
clouding, scratching, erosion, or corrosion. The glass
should be inspected daily until the need for replace-
ment becomes apparent. This will help establish the
routine inspection and routine replacement schedules.
CLEANING
Use commercial non-abrasive glass cleaners to keep
glass clean. Use diluted acids such as Hydrochloric
(muriatic) acid when regular cleaners do not seem to
work. Do not use wire brushes or any other abrasive
materials which could scratch the glass.
INSPECTION
Examine the surface of the glass for scratches, corro-
sion, chips, cracks, surface flaws, or nicks. To do this,
shine a very bright concentrated light at an angle of
about 45 degrees.A defective glass will glisten as the
light strikes imperfections. Glass which appears cloudy
or roughened, and will not respond to cleaning,
should be replaced.
STORING
Keep gauge glass in original packaging until ready to
install.
