Johnson Controls tyco AQUAMIST ULF AM15 Manual

Ultra Low Flow AQUAMIST Nozzle
Type ULF AM15
Non-Automatic (Open)
General
Description
The TYCO Ultra Low Flow AQUAMIST
Nozzle Type ULF AM15 is an upright,
stainless steel, open (non-automatic)
intermediate pressure nozzle which uti-
lizes a single fluid jet impinging on a dif-
fuser to produce a spray having a range
of water droplet sizes. It is intended for
use in engineered, water mist deluge
systems in marine applications under
the Guidelines for Approval of Fixed
Water-Based Local Application Fire –
Fighting Systems for Use in Category
A Machinery Spaces, MSC/Circ. 913
(4 June 1999).
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 AM15 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
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.

any other authorities having jurisdiction.
Failure to do so may impair the perfor-
mance 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 product manufacturer with any
questions.

Criteria
Obtain guidance for the design of
a watermist system that utilizes the
TYCO Type ULF AM15 AQUAMIST
Nozzles from the Technical Services
Department.
Installation
The TYCO Type ULF AM15 AQUAMIST
Nozzles must be installed in accor-
dance with this section:
General Instructions
A leak tight 1/2 in. NPT nozzle joint
½
)
should be obtained with a torque of
7 to 14 lb-ft (9,5 to 19,0 N·m). Higher
levels of torque may distort the nozzle
inlet and cause leakage or impairment
of the nozzle.
Nozzles must be installed using 0.1 m
minimum length pipe extensions as
illustrated in Figure 3.
Step 1. With pipe thread sealant
applied to the pipe threads, hand
tighten the nozzle into the nozzle fitting.
Step 2. Tighten the nozzle into the
nozzle fitting using only the W-Type 11
Sprinkler Wrench (Ref. Figure 2). With
reference to Figure 1, the W-Type 11
Sprinkler Wrench is to be applied to
the wrenching area.
