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
The TYCO Ultra Low Flow AQUAMIST
Nozzles Type ULF AM22 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.
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 AM22 AQUAMIST
Nozzles described herein must be
installed and maintained in compliance
with this document, as well as with the
applicable 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 per-
formance 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.

Design
Criteria
Obtain guidance for the design of a
water-mist system that utilizes the
TYCO Type ULF AM22 AQUAMIST
Nozzles from the Technical Services
department.
The Type ULF AM22 can only be
installed in non-recessed applications.
Installation
The TYCO Type ULF AM22 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 in.) for the 57°C (135°F) to 2,4 mm
(3/32 in.) for the 93°C (200°F) tempera-
ture ratings.
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 lb-ft). Higher levels
of torque can distort the nozzle inlet
and cause leakage or impairment of
the nozzle.
For flush installations, use the Style 20
Escutcheon.
Step 1. Install the Type ULF AM22
Nozzle 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
Nozzle Wrench, refer to Figure 2. With
reference to Figure 1, apply the wrench
to the Nozzle Wrench Flats.

Note: Do not attempt to compen-
sate for insufficient adjustment in the
escutcheon plate by under or over-
tightening the nozzle. Re-adjust the
position of the nozzle fitting to suit.
Absence of an escutcheon, which is
used to cover a clearance hole, can
delay the time to nozzle operation in a
fire situation.
Care and
Maintenance
The TYCO Type ULF AM22 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 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,
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 the NATIONAL FIRE PROTECTION
ASSOCIATION (e.g., NFPA 20, 25, and
750), in addition to the standards of
any other authorities having jurisdic-
tion. Contact the installing contrac-
tor or product manufacturer with any
questions.
Water-mist fixed systems should be
inspected, tested, and maintained by
a qualified Inspection Service in accor-
dance with local requirements and/or
national codes.
