Installation
The Series TY-B Sprinklers must be
installed in accordance with the follow-
ing instructions:
NOTES
Do not install any bulb type sprinkler if
the bulb is cracked or there is a loss of
liquid from the bulb. With the sprinkler
held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm) for the 135°F/57°C to 3/32
inch (2,4 mm) for the 360°F/182°C
temperature ratings.
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 maxi-
mum of 21 ft. lbs. (28,5 Nm) of torque
may be used to install sprinklers with
1/2 NPT connections. Higher levels of
torque may distort the sprinkler inlet
with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to make-up for insuffi-
cient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Readjust the position of the
sprinkler fitting to suit.
The
Series TY-B Horizontal and Ver-
tical Sidewall Sprinklers
must be in-
stalled in accordance with the follow-
ing instructions.
Step 1.
Horizontal sidewall sprinklers
are to be installed in the horizontal
position with their centerline of water-
way perpendicular to the back wall and
parallel to the ceiling. The word “TOP”
on the Deflector is to face towards the
ceiling.
Vertical sidewall sprinklers are to be
installed in the pendent or upright po-
sition with the arrow on the Deflector
pointing away from the wall.
Step 2.
With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.
Step 3.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
6 Sprinkler Wrench (Ref. Figure 4),
except that an 8 or 10 inch adjustable
Crescent wrench is to be used for wax
coated sprinklers. With reference to
Figure 1 or 2, the W-Type 6 Sprinkler
Wrench or the Crescent wrench, as
applicable, is to be applied to the
wrench flats.
When installing wax coated sprinklers
with the adjustable Crescent wrench,
additional care needs to be exercised
to prevent damage to the wax coating
on the sprinkler wrench flats or frame
arms and, consequently, exposure of
bare metal to the corrosive environ-
ment. The jaws of the wrench should
be opened sufficiently wide to pass
over the wrench flats without damag-
ing the wax coating. Before wrench
tightening the sprinkler, the jaws of the
wrench are to be adjusted to just con-
tact the sprinkler wrench flats. After
wrench tightening the sprinkler, loosen
the wrench jaws before removing the
wrench.
After installation, the sprinkler wrench
flats and frame arms must be in-
spected and the wax coating re-
touched (repaired) whenever the coat-
ing has been damaged and bare metal
is exposed. The wax coating on the
wrench flats can be retouched by gen-
tly applying a heated 1/8 inch diameter
steel rod to the areas of wax that have
been damaged, to smooth it back over
areas where bare metal is exposed.
NOTES
Only retouching of the wax coating ap-
plied to the wrench flats and frame
arms is permitted, and the retouching
is to be performed only at the time of
the initial sprinkler installation.
The steel rod should be heated only to
the point at which it can begin to melt
the wax, and appropriate precautions
need to be taken, when handling the
