The PA-4020B is enclosed in a chassis, which is
devoid of ventilation holes. Consequently, it is by-
and-large impervious to happenstance’s where
liquid or other corrosive elements can be intro-
duced into the interior of the chassis. However,
the external connections on the rear panel of the
amplifier could be adversely effected by exposure
to water or other liquids. Hence, as a general
precaution, the unit should not be operated in a
location where it might be subjected to water or
other spilled liquids.

other than the USA, adhere to local codes and
standards for specifics.
Do not make any modifications that will
defeat the grounding provisions of the unit.
