If a sprinkler must be removed for any reason, do not reinstall it or a replacement without reinstalling the Cover
Plate Assembly. If a Cover Plate Assembly becomes dislodged during service, replace it immediately.
Properly installed sprinklers must have a nominal 3/32" (2.4mm) air gap between the lip of Cover Plate
and the ceiling. The air gap is necessary for the proper operation of the sprinkler. If the ceiling is to
be painted after installation of the Cover Plate Assembly, care must be taken to ensure that new paint
does NOT seal off the nominal 3/32" (2.4mm) air gap.
Sprinklers and or cover plates must not be painted, coated or otherwise altered after leaving the factory.
Sprinklers that have been exposed to corrosive products of combustion, but have not operated, must
be replaced.
