Troubleshooting

5.1. Leakage of retrofitted or reinstalled sprinkler
Leakage can be caused e.g. when the O-ring is not replaced and the Spacer
plate is used, when the O-ring is damaged or misplaced, or when the sealing
surface on the sprinkler or the Assembly Body is scratched or contaminated.
Corrective actions:
-
Depressurise the system
-
Remove the sprinkler and make sure that all the surfaces of the
sprinkler and the Assembly Body are clean and undamaged
-
Replace the O-Ring and make sure it sits properly in its groove
5.2. Assembly Body type is not visibly like the listed types
The Safety Bulletin and this document focus on the relevant types, which are
connected to the ceiling by assembly plates, and to several similar models.
Other types, e.g. models that are wall mounted, or that are bolted directly to the
surface, do not require further action.
Exposed A1000 Assembly Bodies, with no cover plate, do require attention.
