IMPORTANT
Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

The smallest waterway (orifice) diam-
eter of the Orifice Insert is nominally
4,4 mm (0�172 inches)� The diameter of
the Inlet Strainer perforations is nomi-
nally 3,2 mm (0�125 inches)�
The design of individual water mist
systems can vary considerably,
depending on the characteristics and
nature of the hazard and the basic
purpose of the water mist system.
Because of these variations, the design
of water mist systems for fire protec-
tion must only be performed by expe-
rienced designers who thoroughly
understand the limitations as well as
capabilities of such systems.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

General
Description
TYCO Ultra Low Flow AQUAMIST
Nozzles Type ULF AM29 are closed
(automatic) nozzles intended for use
with engineered, water mist systems�
They are low-pressure nozzles that
utilize a single fluid jet impinging on a
diffuser to produce a spray having a
range of water droplet sizes suitable
for the control of Class A fires and the
protection of data centers�
It is recommended that the end user be
consulted with respect to the suitabil-
ity of the materials of construction and
finish for any given corrosive environ-
ment� The effects of ambient tempera-
ture, concentration of chemicals, and
gas/chemical velocity should be con-
sidered, at a minimum, along with the
corrosive nature to which the nozzles
may be exposed�
NOTICE
The Type ULF AM29 AQUAMIST
Nozzles described herein must be
installed and maintained in compliance
with this document and with the appli-
cable standards of the NATIONAL FIRE
PROTECTION ASSOCIATION (NFPA),
in addition to the standards of any
authorities having jurisdiction. Failure
to do so may impair the performance
of these devices.

Design
Criteria
Obtain guidance for the design of a
water-mist system that utilizes the
TYCO Type ULF AM29 AQUAMIST
Nozzles from the Technical Services
department�
Installation
TYCO Type ULF AM29 AQUAMIST
Nozzles must be installed in accor-
dance with this section�
General Instructions
Do not install any bulb type nozzle if
the bulb is cracked or there is a loss
of liquid from the bulb� With the nozzle
held horizontally, a small air bubble
should be present� The diameter of
the air bubble is approximately 1,6 mm
(1/16 inch) for the 57°C (135°F) to 2,4
mm (3/32 inch) for the 182°C (360°F)
temperature ratings�
A leak-tight 1/2 inch NPT nozzle
joint should be obtained by apply-
ing a minimum-to-maximum torque of
9,5 to 19,0 Nm (7 to 14 ft�-lbs�)� Higher
levels of torque can distort the nozzle
inlet and cause leakage or impairment
of the nozzle�
Do not attempt to compensate for
insufficient adjustment in the escutch-
eon plate by under- or over-tightening
the nozzle� Re-adjust the position of the
nozzle fitting to suit�
Type ULF AM29
The Type ULF AM29 AQUAMIST
Nozzles must be installed in accor-
dance with the following instructions�
Step 1. Install the Type ULF AM29 in the
pendent position as shown in Figure 1�
Step 2. With pipe-thread sealant
applied to the pipe threads, hand-
tighten the nozzle into the nozzle fitting�
Step 3. Tighten the nozzle into the
nozzle fitting using only the W-Type 6
Sprinkler Wrench (Ref� Figure 3)� With
reference to Figure 1, apply the W-Type
6 Sprinkler Wrench to the wrench flats�
Type ULF AM29 Recessed
The Type ULF AM29 AQUAMIST
Recessed Nozzles must be installed
in accordance with the following
instructions�
Step A. Install the Recessed Type ULF
AM29 in the pendent position as shown
in Figure 2�
Step B. After installing the Style 20
Mounting Plate, as applicable, over
the nozzle threads and with pipe-thread
sealant applied to the pipe threads,
hand-tighten the nozzle into the nozzle
fitting�
Step C. Tighten the nozzle into the
nozzle fitting using only the W-Type 7
Recessed Sprinkler Wrench (refer to
Figure 4)� With reference to Figure 1,
apply the W-Type 7 Recessed Sprin-
kler Wrench to the nozzle wrench flats�

Step D. After the ceiling has been
installed or the finish coat has been
applied, slide on the Style 20 Closure
over the Type ULF AM29 Nozzle and
push the Closure over the Mounting
Plate until its flange comes in contact
with the ceiling�
Note: Absence of a Style 20 Recessed
Escutcheon, which is used to cover a
clearance hole, can delay the time to
nozzle operation in a fire situation.
Care and
Maintenance
TYCO Type ULF AM29 AQUAMIST
Nozzles must be maintained and ser-
viced 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, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this action�
Nozzles that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced�
Automatic nozzles must never be
painted, plated, coated, or other-
wise altered after leaving the factory�
Modified nozzles must be replaced�
Nozzles that have been exposed to
corrosive products of combustion but
have not operated should be replaced
if they cannot be completed cleaned
by wiping the nozzle with a cloth or by
brushing it with a soft bristle brush�
Care must be exercised to avoid
damage to the nozzles before, during,
and after installation� Nozzles damaged
by dropping, striking, wrench twist/
slippage, or the like, must be replaced�
Also replace any nozzle that has a
cracked bulb or that has lost liquid from
its bulb (Ref� Installation section�)
Frequent visual inspections are rec-
ommended to be initially performed
for nozzles installed in potentially cor-
rosive atmospheres to verify the integ-
rity of the materials of construction
and finish as they may be affected by
the corrosive conditions present for a
given installation� Thereafter, annual
inspections per NFPA 25 are required,
in addition to inspections required by
the authority having jurisdiction�
The owner is responsible for the
inspection, 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
ASSOCIATION - for example, NFPA 20,
25, and 750 - in addition to the stan-
dards of any other authorities having
jurisdiction� Contact the installing con-
tractor or product manufacturer with
any questions�
Water mist systems should be in-
spected, tested, and maintained by a
qualified Inspection Service in accor-
dance with local requirements and/or
national codes�
