NOTES
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 ft.lbs. (9,5 to 19,0 Nm). A maximum
of 21 ft.lbs. (28,5 Nm) of torque is to be
used to install 1/2 inch NPT sprinklers.
Higher levels of torque may distort the
sprinkler inlet with consequent leakage
or impairment of the sprinkler.
Do not attempt to make up for insuffi-
cient adjustment in the escutcheon plate
by under- or overtightening the sprin-
kler. Readjust the position of the
sprinkler fitting to suit.
Installation
Step 1. Pendent sprinklers must be
installed only in the pendent position.
The deflector is to be parallel to the
ceiling, roof, or mounting surface, as
applicable.
Step 2. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the Universal
Wrench (Ref. Figure 4). With reference
to Figure 1 or 2, the Universal Wrench
is to be applied to the sprinkler wrench
flats only.
After the ceiling has been installed or
the finish coat has been applied, slide
on the Model A/H Recessed Escutcheon

Installation of the Model A/H Reccesed
Escutcheon can be accomplished by
hand or by using the Recessed
Escutcheon Tool (Ref. Figure 5) and a
telescoping pole assembly. Every
Model H Recessed Escutcheon has 4
tabs on the interior opening of the
escutheon. By matching these tabs to
the corresponding groove on the
Recessed Escutcheon Tool and with
the telescoping pole attached, the
recessed escutcheon can be installed
without the aid of a ladder. Care should
be exercised to assure that the Actuator
Rod and Ejector Springs of the sprinkler
are not dammaged during the installa-
tion of the recessed escutcheon.
