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 Type AM31 AQUAMIST
Nozzle is a stainless steel, open (non-
automatic) pendent nozzle intended for
use with engineered, watermist deluge
systems. It is an intermediate pressure
nozzle which utilizes a single fluid jet
impinging on a diffuser to produce a
spray having a range of water droplet
sizes suitable for the extinguishment
of Class K fires within industrial frying
equipment.
The Type AM31 Nozzle may be installed
in exposed pendent applications using
standard pipe and threaded fittings.
They may also be installed in recessed
pendent applications using a unique
threaded or socket-weld fitting with
integrated tethered cap assembly. The
cap conceals the nozzle, separating
during system discharge but remaining
attached by a sturdy length of chain.
Refer to Technical Data Sheet TFP2242
for further details on the TYCO
Threaded or Socket-Weld Fittings.
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 Type AM31 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.
The design of individual watermist
systems can vary considerably,
depending on the characteristics and
nature of the hazard and the basic
purpose of the watermist system.
Because of these variations, the design
of watermist 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 sprinkler manufacturer with any
questions.

Design
Criteria
Obtain guidance for the design of a
watermist system that utilizes the TYCO
Type AM31 AQUAMIST Nozzle from the
Technical Services Department.
The Type AM31 AQUAMIST Nozzle can
be installed in the pendent or angular
position.
Installation
The TYCO Type AM31 AQUAMIST
Nozzle must be installed in accordance
with this section.
General Instructions
A leak-tight 1/2 inch NPT Nozzle joint
should be obtained by applying a min-
imum-to-maximum torque of 7 to 14
ft.-lbs. (9,5 to 19,0 Nm). Higher levels
of torque can distort the nozzle inlet
and cause leakage or impairment of
the nozzle.
Step 1. With TEFLON paste sealant
applied to Nozzle threads, hand tighten
Nozzle into nozzle fitting.
Step 2. Tighten nozzle into 1/2 inch
NPT nozzle fitting using only W-Type
6 Wrench (Figure 2). With reference
to Figure 1, W-Type 6 Wrench is to be
applied only to Wrench Flats.

Care and
Maintenance
The TYCO AQUAMIST Nozzle Type
AM31 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.
Type AM31 AQUAMIST Nozzle must
never be painted, plated, coated or
altered in any way after leaving the
factory; otherwise, the spray perfor-
mance may be impaired.
Care must be exercised to avoid
damage to the nozzles -before, during,
and after installation. Nozzles damaged
by dropping, striking, wrench twist/slip-
page, or the like, must be replaced.
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 inspec-
tions per NFPA 25 are required.
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 25,
in addition to the standards of any other
authorities having jurisdiction. Contact
the installing contractor or sprinkler
manufacturer with any questions.
Water spray fixed systems should be
inspected, tested, and maintained by
a qualified Inspection Service in accor-
dance with local requirements and/or
national codes
