Installation and Maintenance Instructions
• After performing any maintenance, test the loudspeaker system to
ensure that it is operating properly.
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.

Maintaining the Loudspeaker

EXPLOSION HAZARD: To prevent ignition of hazardous
atmosphere, disconnect the loudspeaker from the audio supply
circuit before opening it. Do not open the loudspeaker in the
presence of explosive gases in the atmosphere. Failure to follow
this warning may result in serious injury or death.
During the working life of the loudspeaker, it should require little or
no maintenance. The non-metallic housing will resist attack by most
acids, alkalis, and chemicals and is as resistant to concentrated acids
and alkalis as most metal products. However, if abnormal or unusual
environment conditions occur due to plant damage or accident, etc.,
visual inspection of the loudspeaker is recommended.

Cleaning the Enclosure

The enclosure should be cleaned periodically with a damp cloth to
maintain maximum sound output. Periodic checks should be made
to ensure the effectiveness of this device has not been reduced
because the loudspeaker has become clogged with a foreign
substance or because objects have been placed in front of the
loudspeaker.

Lubricating the Threaded Joints

A silicone based, non-hardening, chemically compatible grease can
be applied if required.
