Replacing the filters
Where displays are installed in an unsealed enclosure, air intake filters should be inspected
yearly, and replaced if noticeably fouled. If vessel is subject to major works involving spray
painting or sanding, it is recommended that the monitor either be removed, or completely
covered in a clean fabric drop cloth.
¼ Note: ZM16 and ZM19 models require three filter elements. The filter accessory kit includes
five elements.
Other maintenance
Only qualified service personnel should perform any repairs that require opening of the case.
! Warning: Some components in the display unit operate on high voltages. Repairs
require specialized service procedures and tools only available to service technicians - there
are no user serviceable parts or adjustments. The operator should never remove the display
unit cover or attempt to service the equipment. Any attempt to do so may make the
warranty invalid.
