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.

General
Description
TYCO Ultra Low Flow AQUAMIST Type
ULF AM28 Nozzles are closed (auto-
matic) 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.
It is recommended that the end user
be consulted with respect to the suit-
ability of the materials of construction
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and gas/
chemical velocity should be consid-
ered, at a minimum, along with the cor-
rosive nature to which the nozzles may
be exposed.
NOTICE
The TYCO Ultra Low Flow AQUAMIST
Type ULF AM28 Nozzles described
herein must be installed and maintained
in compliance with this document and
with the applicable standards of the
VdS CEA 4001 “Sprinkler Systems
Planning and Installation” or EN12845
“Automatic Sprinkler Systems - Design,
Installation and Maintenance”, in addi-
tion to the standards of any authorities
having jurisdiction. Failure to do so
may impair the performance of these
devices.
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.
Approvals
The TYCO Type ULF AM28 AQUAMIST
Nozzles are VdS approved when used
as part of an engineered, wet-pipe
water mist system. In particular, the
VdS approval was performed in accor-
dance with test protocols “Fire tests
for ‘Office, OH1’ and similar” dated
December 6, 2007, and “Fire tests for
‘Hotel, OH1’ and similar” dated October
10, 2011.

Installation
TYCO Ultra Low Flow AQUAMIST Type
ULF AM28 Nozzles must be installed in
accordance with this section.
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 in.) for the 57°C (135°F) tempera-
ture rating.
A leak-tight 1/2 inch NPT nozzle joint
should be obtained by applying a min-
imum-to-maximum torque of 9,5 to
19,0 N·m (7 to 14 ft-lb). Higher levels
of torque can distort the nozzle inlet
and cause leakage or impairment of
the nozzle.
Type ULF AM28
The Type ULF AM28 AQUAMIST
Nozzles must be installed in accor-
dance with the following instructions:
Step 1. Install the Type ULF AM28 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
Wrench (Ref. to Figure 2). With refer-
ence to Figure 1, apply the W-Type 6
Wrench to the wrench flats.

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 recom-
mended to be initially performed for
nozzles installed in potentially corro-
sive 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 applicable standards
are required, in addition to inspec-
tions 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 any other authorities having juris-
diction. Contact the installing contrac-
tor 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.
Care and
Maintenance
TYCO Ultra Low Flow AQUAMIST Type
ULF AM28 Nozzles 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, 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 which 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 completely 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,
