Use Sentry Sprinklers recommended wrench to install the sprinkler. Slide the sprinkler wrench around
the sprinkler frame arms and press the wrench down to engage sprinkler wrench flats. Rotate the
wrench clockwise to tighten the sprinkler head. The frame arms must be parallel to the pipe. Never
tighten the sprinkler from sprinkler arms. Any torque applied to the frame arms will dislodge the bulb
seating assembly causing the sprinkler to leak.
The concealed sprinkler must not be used in any application where the air pressure above the ceiling
is greater than that below it. Downdraft through the Mounting Cup could delay sprinkler operation in a
fire condition.
Only use Sentry Sprinklers recommended wrench to install the sprinkler.
Exercise caution when installing the sprinkler. If the sprinkler is damaged during installation, do not
attempt to fix it, replace it immediately.
After the ceiling has been completed with a 2 ½” (64mm) to 2
13/16” (72mm) diameter clearance hole, remove and discard
the protective cap and verify that the sprinkler is intact.
Do not attempt to make up for insufcient adjustment in
the sprinkler assembly by under or overtightening the
sprinkler Mounting Cup Assembly. Instead, readjust the
position of the sprinkler tting.
Do not remove Sprinkler Protective Cap until you are
ready to install the Cover Plate Assembly.
Absence of the Cover Plate Assembly may delay the sprinkler
operation time in a fire situation.
For additional details, refer to NFPA and UL for installation
guidelines.
