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.
