CAUTION
Possible service degradation due to electrical
interference
Series-wound motors cause electromagnetic
interference.
Vacuum OPAC frames to prevent the increase of electrostatic discharges that
dust causes. Use a vacuum cleaner with an induction-wound brushless motor
and plastic or rubber attachments. You can use battery-operated vacuum
cleaners. Vacuum inside and around the frames at each inspection of the the
OPAC filters. Do not bump any part of the frame. Avoid metal-to-metal contact.
