Installation
Model N252 sprinklers are to be installed as
shown. Model FP escutcheons, illustrated herewith,
are the only recessed escutcheons to be used with
Model N252 EC Recessed Pendent Sprinklers. Use
of any other recessed escutcheon will void all
approvals and warranties. When handling
sprinklers, hold sprinklers only on frame arms and do
not apply any force on the link assembly. For
installing Model N252 EC pendent and recessed
pendent sprinklers use only the Model N wrench (ref.
Fig. 3). Use of wrenches other than that specified may
damage these sprinklers. Sprinklers should be
tightened between 22 to 30 ft. - lbs. (29,8 - 40,7 Nm)
torque. Sprinklers not tightened
to recommended
torque may cause
leakage or impairment of the
sprinklers. Damaged sprinklers must be replaced
immediately.
