Installation
TYCO Series LFII Residential 4.9K
Pendent and Recessed Pendent Sprin-
klers must be installed 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 horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 in.
(1,6 mm).
A leak-tight 1/2 in. NPT sprinkler
joint should be obtained by apply-
ing a minimum-to-maximum torque of
7 to 14 lb-ft (9,5 to 19,0 N∙m). Higher
levels of torque can distort the sprin-
kler Inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in an Escutch-
eon Plate by under- or over- tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Pendent Sprinklers
The Series LFII Residential Pendent
Sprinklers must be installed in accor-
dance with the following instructions.
Step 1. Install pendent sprinklers in the
pendent position with the deflector par-
allel to the ceiling.
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 W-Type
6 Sprinkler Wrench, as shown in Figure
4. With reference to Figure 1, apply
the W-Type 6 Sprinkler Wrench to the
wrench flats.
Recessed Pendent Sprinklers
The Series LFII Residential Recessed
Pendent Sprinklers must be installed
in accordance with the following
instructions.
Step A. Install the recessed pendent
sprinklers in the pendent position with
the deflector parallel to the ceiling.
Step B. After installing either the
Style 15 or the Style 20 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 C. Tighten the sprinkler into the
sprinkler fitting using only the W-Type 7
Recessed Sprinkler Wrench, as shown
in Figure 5. With reference to Figure 1,
apply the W-Type 7 Recessed Sprinkler
Wrench to the sprinkler wrench flats.
Step D. After the ceiling has been
installed, or the finish coat has been
applied, slide on either the Style 15
Closure or the Style 20 Closure over the
Series LFII Residential Sprinkler and
push the Closure over the Mounting
Plate until its flange comes in contact
with the ceiling.
Care and
Maintenance
TYCO Series LFII Residential 4.9K
Pendent and Recessed Pendent Sprin-
klers must be maintained and serviced
in accordance with this section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the outer piece of an
escutcheon, which is used to cover
a clearance hole, can delay sprinkler
operation in a fire situation.
The owner must assure that the sprin-
klers are not used for hanging any
objects and that the sprinklers are only
cleaned by means of gently dusting
with a feather duster; otherwise, non-
operation in the event of a fire or inad-
vertent operation may result.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
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. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. See the Installation
section.
The owner is responsible for the inspec-
tion, testing, and maintenance of their
fire protection system and devices in
compliance with this document, as well
as with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION, such as NFPA 25, in addi-
tion to the standards of any authorities
having jurisdiction. Contact the install-
ing contractor or product manufacturer
with any questions.
