Operation
When the glass bulb reaches its rated
temperature of 155°F (68°C) or 200°F
(93°C), the glass bulb bursts allowing
the sprinkler to activate and flow water.
Installation
Install the TYCO Model TY7258
Pendent Sprinkler in accordance with
this section.
General Instructions
Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontal, a small air bubble
should be present. For the Model
TY7258 Sprinkler, the diameter of the
air bubble is approximately 1/16 inch
( 7, 0 m m) .
A leak tight 3/4 inch NPT sprinkler joint
should be obtained with a torque of 10
to 20 ft.-lbs. (13,4 to 26,8 Nm). Higher
levels of torque can distort the sprin-
kler inlet with consequent leakage or
impairment of the sprinkler.
Model TY7258 Pendent Sprinkler
The Model TY7258 Pendent Sprinklers
must be installed in accordance with
the following instructions:
Step 1. Apply pipe-thread sealant to
sprinkler threads.
Step 2. Hand-tighten the sprinkler into
the sprinkler fitting. Do not apply force
to the glass bulb, grasp only by wrench
flats while hand-tightening.
Step 3. Wrench tighten the Model
TY7258 Sprinkler using only the W-Type
8 Sprinkler Wrench (Ref. Figure 2) and
by fully engaging (seating) the wrench
on the sprinkler wrench flats.
Model TY7258 Recessed Pendent
Sprinkler with Style 30 Escutcheon
The Model TY7258 Recessed Pendent
Sprinklers must be installed in accor-
dance with the following instructions.
Step 1. After installing the Style 30
Escutcheon Mounting Plate over the
sprinkler threads, and with pipe thread
sealant applied to the pipe threads,
hand tighten the sprinkler into the
sprinkler fitting.
Step 2. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
38 Sprinkler Wrench (Ref. Figure 3).
With reference to Figure 4, apply the
W-Type 38 Recessed Sprinkler Wrench
to the sprinkler wrench flats.
Step 3. After the ceiling is installed,
slide the Style 30 Escutcheon Closure
over the Model TY7258 Sprinkler and
push the closure over the mounting
plate until its flange comes in contact
with the ceiling.
Model TY7258 Pendent Sprinkler
with Style 65 Escutcheon
The pipe connected to the sprin-
kler fitting must be cut to locate the
escutcheon plate seating surface at the
proper nominal distance in front of the
wall or below the ceiling. Manufacturing
variations in the take-out of the fittings
as well as the make-in of the sprinklers
(as permitted by ANSI B1.20.1) may
require that trial cuts of the connecting
pipe be made.
Step 1. After installation of the Style
65 Escutcheon Plate over the sprinkler
threads, and with pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 2. Wrench tighten the sprinkler
into the sprinkler fitting using only the
W-Type 8 Sprinkler Wrench (Ref. Figure
2). With reference to Figure 5, apply
the W-Type 8 Sprinkler Wrench to the
sprinkler wrench flats.
Model TY7258 Pendent Sprinkler
with Style 401 Escutcheon
Step 1. After installation of the Style
401 Escutcheon Cup over the sprinkler
threads, and with pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 2. Wrench tighten the sprinkler
into the sprinkler fitting using only the
W-Type 8 Sprinkler Wrench (Ref. Figure
2). With reference to Figure 6, apply
the W-Type 8 Sprinkler Wrench to the
sprinkler wrench flats.
Step 3. After the ceiling is installed,
align the detents in the escutcheon skirt
over those in the cup and then slide
the skirt over the cup until it comes
in contact with the mounting surface.
Do not push the skirt such that it lifts
a ceiling tile out of its normal posi-
tion. Holding the skirt in contact with
the mounting surface, rotate approxi-
mately 1/8-turn relative to the cup, cre-
ating a friction fit between skirt detents
and cup surface to hold the Style 401
Escutcheon firmly together.
