mum of 21 ft.lbs. (28,5 Nm) of torque
is to be used to install sprinklers.
Higher levels of torque may distort the
sprinkler inlet with consequent leak-
age or impairment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in an Escutcheon
Plate by under- or over-tightening the
Sprinkler. Readjust the position of the
sprinkler fitting to suit.
Step 1. The sprinkler must only be
installed in the pendent position and
with the centerline of the sprinkler per-
pendicular to the mounting surface.
Step 2. Remove the Protective Cap.
Step 3. With pipe thread sealant ap-
plied to the pipe threads, and using
the W-Type 18 Wrench shown in Fig-
ure 2, install and tighten the Sprink-
ler/Support Cup Assembly into the fit-
ting. The W-Type 18 Wrench will
accept a 1/2 inch ratchet drive.
