Background information

Installation of HI-FOG sprinklers consists of HI-FOG sprinkler inserted into a
specifically built Assembly Body, also known as 'Mounting Adaptor'.
The A1000 Assembly Bodies were built to accommodate the HI-FOG 1000
sprinklers. Some types of this Assembly Body include an internal stop valve that
prevents the flow through the Assembly Body if the sprinkler is removed.
The HI-FOG 1900 sprinklers have been developed as replacement of HI-FOG
1000 sprinklers using some of the improvements presented in the HI-FOG 2000
sprinklers.
For some of the Assembly Body type A1000, there is a risk that a HI-FOG 1900
sprinkler will press the internal stop valve beyond the intended range and thus
may diminish or in the worst case prevent the water flow to the sprinkler in case of
discharge.
The risk is limited to the specific Assembly Body types, used in combination with
HI-FOG 1900 sprinklers.
The risk does not extend to other Assembly Body types, to Assembly Bodies
without internal stop valve or to any other HI-FOG sprinklers with any Assembly
Body.
See details in the following sections to identify the affected components.
