1. In stall all pip ing and cut the sprin -
kler nip ple so that the ½" (15 mm)
NPT out let of the re duc ing cou -
pling is at the de sired lo ca tion and
cen tered in a 2-1/4" (57,22 mm)
di am e ter open ing in the wall (due
to the lockring).
Note: If the re tain ing flange as -
sem bly is to be used, slide the
flange over the sprin kler nip ple
prior to thread ing the nip ple into
the tee, as shown in Fig ure 3A.

is de signed for use with the sprin -

the shell, ap ply a small amount of
pipe-joint com pound or tape to the
ex ter nal threads of the sprin kler
only, tak ing care not to al low a
build-up of com pound in the sprin -

klers. With the sprin kler in the
plas tic pro tec tive shell, place the
unit into the wrench. DO NOT use
the fus ible link to start or thread
the sprin kler into a fit ting. Turn the
unit clock wise to thread the sprin -
kler into the cou pling, tak ing care
not to over-tighten or dam age the
sprin kler op er at ing parts.
G. Af ter in stal la tion, the en tire sprin kler
sys tem must be tested. The test must
be con ducted to com ply with the in -
stal la tion stan dards.
Make sure the sprin kler has been
prop erly tight ened. If a thread leak
oc curs, nor mally the sprin kler must
be re moved, new pipe-joint com -
pound or tape ap plied, and then re in -
stalled. This is due to the fact that
when the joint seal is dam aged, the
seal ing com pound or tape is washed
out of the joint.
H. Af ter test ing, re pair ing all leaks, and
in stall ing and paint ing the wall, re -
move the plas tic pro tec tive shell from
the sprin kler.
IN STAL LA TION TIP:
Do not in stall the
lockring onto the sprin kler un til af ter the
sprin kler nip ple has been cut back to en -
sure de sired place ment of the sprin kler
in re la tion to the outer sur face of the
wall. The lockring will prove dif fi cult to
re move from the sprin kler once it has
been in stalled be hind the face of the
wall. Check fin ished prod uct by tem po -
rarily in stall ing the es cutch eon plate
onto the sprin kler with out the lockring,
us ing the In sti tu tional Es cutch eon In -
stal la tion Wrench. If nec es sary, re-cut
the sprin kler nip ple as re quired.
Once sat is fied with sprin kler lo ca tion
com pared to the front of the wall, in stall
the lockring and the es cutch eon plate
fol low ing steps I through K on this page.
The es cutch eon plate can not be re -
moved af ter it has been in stalled with
the lockring, so do not in stall the es -
cutch eon plate with the lockring un til af -
ter the sys tem has been tested.
I. As shown in Fig ures 3C and 3D, fit the
lockring over the open end of the pro -
tec tive sprin kler shell and use the
shell to gently press the lockring over
the threads of the sprin kler. The ring
must rest against the two wrench
ears of the sprin kler body with the
four arms of the lockring point ing out -
ward.
J. RE MOVE THE PLAS TIC PRO TEC -
TIVE SHELL from the sprin kler.
(Rec om men da tion: re tain a pro tec -
tive shell in the spare sprin kler cab i -
net.)
K. As de picted in Fig ure 3E, use the In -
sti tu tional Es cutch eon In stal la tion
Wrench to screw on the es cutch eon
plate clock wise. The face of the es -
cutch eon plate is equipped with four
in den ta tions to com ple ment the de -
sign of the In sti tu tional Es cutch eon
In stal la tion Wrench and fa cil i tate in -
stal la tion of the es cutch eon plate.
As the es cutch eon plate is threaded
onto the sprin kler body, the four arms
of the lockring must fully en gage with
the ra dial grooves on the in side of the
es cutch eon plate. Con tinue to thread
the es cutch eon plate onto the sprin -
kler body un til the plate’s flange fits
tightly against the sur face of the wall.
Then, pro ceed to turn the es cutch -
eon plate an other ½ turn clock wise to
en sure that it is se cured to the wall.
The arms of the lockring are an gled
and de signed to wedge into the
coined ra dial grooves on the in side
face of the es cutch eon plate to keep
the es cutch eon plate from be ing un -
screwed. Thus, an at tempt to re move
the es cutch eon plate is pre vented af -
ter it is in stalled with the lockring. DO
NOT MODIFY THE UNIT.
L. The re tain ing flange, lo cated be hind
the wall, must fit snug against the in -
ner sur face of the wall to pre vent ver -
ti cal move ment of the as sem bly. Use
a 1/8" hex wrench to tighten the re -
tain ing flange screw and se cure the
as sem bly into place to pre vent it from
be ing pulled through the wall.
