K-factor applies for standard lengths ("A" Dimensions indicated above). Metric K-Factor shown is for use when pressure is measured in kPa.
When pressure is measured in BAR, multiply the metric K-Factor shown by 10.0.

should be given to employment of a fire
patrol in the effected area.
1. Remove the system from service,
drain all water, and relieve all pres-
sure on the piping.
2. Using the special sprinkler wrench,
remove the old sprinkler and install
the new unit. Care must be taken to
ensure that the replacement sprin-
kler is the proper model and style,
with the appropriate "A" dimension,
orifice size, temperature rating, and
response characteristics.
3. Place the system back in service
and secure all valves. Check for and
repair all leaks.
E. Sprinkler systems that have been sub-
jected to a fire must be returned to ser-
vice as soon as possible. The entire
system must be inspected for damage
and repaired or replaced as necessary.
Sprinklers that have been exposed to
corrosive products of combustion or
high ambient temperatures, but have
not operated, should be replaced. Re-
fer to the AHJ for minimum replace-
ment requirements.
