Installation
The TYCO Series TY-L 5.6 and
8.0 K-factor Upright, Pendent, and
Recessed Pendent Sprinklers must
be installed in accordance with this
section.
General Instructions
A leak tight 1/2 in. NPT sprinkler joint
should be obtained with a torque of
7 ft-lb to 14 ft-lb (9,5 N·m to 19,0 N·m).
A leak- tight 3/4 in. NPT sprinkler joint
should be obtained with a torque of
10 ft-lb to 20 ft-lb (13,4 N·m to
26,8N·m). Higher levels of torque may
distort the sprinkler inlet and cause
leakage or impairment of the sprinkler.
Do not attempt to compensate for
insufcient adjustment in the escutch-
eon plate by under- or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler tting to suit.
Series TY-L Upright and Pendent
Sprinklers Installation
The Series TY-L Pendent and Upright
Sprinklers must be installed in accor-
dance with the following instructions:
Step 1. Install pendent sprinklers in the
pendent position. Install upright sprin-
klers in the upright position.
Step 2. With pipe thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step 3. Tighten the sprinkler into the
sprinkler tting using only the W-Type
9 Sprinkler Wrench as shown in Figure
7. For wax coated sprinklers, use an 8
or 10 in. adjustable Crescent wrench.
Apply the W-Type 9 Sprinkler Wrench
to the wrench area as shown in Figures
1, 2, or 3, or as applicable, apply the
adjustable Crescent wrench to the
wrenching anges.
Wax Coated Sprinklers
When installing wax-coated sprinklers
with the adjustable Crescent wrench,
take care to prevent damage to the
wax coating on the sprinkler wrench
ats or frame arms and, consequently,
exposure of bare metal to the corrosive
environment:
• Open the jaws of the wrench suf-
ciently wide to pass over the wrench
flats without damaging the wax
coating.
• Before wrench tightening the sprin-
kler, adjust the jaws of the wrench to
just contact the sprinkler ats.
• After wrench tightening the sprin-
kler, loosen the wrench jaws before
removing the wrench.
Care and
Maintenance
The TYCO Series TY-L 5.6 and
8.0 K-factor Upright, Pendent, and
Recessed Pendent Sprinklers must be
maintained and serviced in accordance
with this section.
Before closing a re protection system
main control valve for maintenance
work on the re protection system that
it controls, permission to shut down the
affected re protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notied.
Absence of an escutcheon, which is
used to cover a clearance hole, may
delay the time to sprinkler operation in
a re situation.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated or otherwise
altered after leaving the factory. Modi-
ed or over-heated sprinklers must be
replaced. Care must be exercised to
avoid damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced.
Frequent visual inspections are rec-
ommended to be initially performed
for corrosion resistant coated sprin-
klers, after the installation has been
completed, to verify the integrity of the
corrosion-resistant coating. Thereafter,
annual inspections per NFPA 25 should
sufce; however, instead of inspecting
from the oor level, a random sampling
of close-up visual inspections should
be made so as to better determine the
exact sprinkler condition and the long-
term integrity of the corrosion resistant
coating, as it may be affected by the
corrosive conditions present.
The owner is responsible for the
inspection, testing, and maintenance of
their re protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION such as NFPA 25, in
addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualied Inspec-
tion Service in accordance with local
requirements and/or national codes.
After Installation
After installation, complete the
following:
• Inspect the sprinkler wrench ats
and frame arms and retouch (repair)
the wax coating whenever the coat-
ing has been damaged and bare
metal is exposed.
• Retouch the wax coating on the
wrench ats by gently applying a
heated 1/8 in. diameter steel rod to
the damaged areas of the wax, to
smooth it back over areas where
bare metal is exposed.
NOTICE
Only retouching of the wax coating
applied 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 it can begin to melt the wax,
and appropriate precautions need to be
taken when handling the heated rod to
prevent the installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuc-
cessful, additional wax can be ordered
in the form of a wax stick, the end of
which is color coded. Only the correct
color coded wax is to be used, and
retouching of wrench flats and frame
arms is only permitted at the time of
initial sprinkler installation.
With the steel rod heated as previ-
ously described, touch the rod to the
area requiring additional wax with the
rod angled downward, and then touch
the wax stick to the rod approximately
1/2 in. (12,7 mm) away from the area
requiring retouching. The wax will melt
and run down onto the sprinkler.
Series TY-L Recessed Pendent
Sprinklers Installation
The Series TY-L Recessed Pendent
Sprinkler must be installed in accor-
dance with the following instructions:
Step 1. After installing the style 20
or 30 mounting plate, as applicable,
over the sprinkler threads and with
pipe thread sealant applied to the pipe
threads, hand-tighten the sprinkler into
the sprinkler tting.
Step 2. Tighten the sprinkler into the
sprinkler tting using only the W-Type
10 recessed sprinkler wrench as shown
in Figure 8. Apply the wrench to the
sprinkler wrenching anges as shown
in Figures 1, 2, or 3.
Step 3. After the ceiling has been
installed or the nish coat has been
applied, slide on the style 20 or 30
closure over the Series TY-L Recessed
Pendent Sprinkler and push the closure
over the mounting plate until its ange
comes in contact with the ceiling.
