Installation
The TYCO Type IFP AQUAMIST
Recessed Nozzle Fittings 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
minimum-to-maximum torque of 7 to
14 lb-ft (9,5 to 19,0 N·m). Higher levels
of torque can distort the nozzle inlet
and cause leakage or impairment of
the nozzle.
NOTICE
The Type AM10 or AM31 AQUAMIST
Nozzle may be factory assembled with
a Recessed IFP Fitting and Cap. If the
nozzles have been pre-assembled,
proceed to Step 5.
Step 1.
Prepare nozzle by applying
TEFLON paste thread sealant to pipe
threads.
Step 2.
Assemble nozzle with Cap
Assembly. Engage nozzle wrench boss
by Link flanges shown in Figures 1 and
2.
Step 3.
Hand tighten nozzle into IFP
fitting until nozzle diffuser is located
3/16 inch (4,8 mm) minimum from face
of fitting.
Step 4.
Tighten nozzle into fitting
using only W-Type 29 Wrench (Figure
5). Guide wrench arm slots over nozzle
frame arms, guide Cap Retention Chain
through wrench chain slot, and engage
Link flanges by wrench tines.
NOTICE
The Recessed IFP Fitting and Cap
may be factory assembled with a Type
AM10 or AM31 AQUAMIST Nozzle. If
pre-assembled, ensure the cap is dis-
lodged from the fitting exposing the
nozzle to facilitate proper orientation
and alignment. Observe nozzle orien-
tation and chain alignment notices pre-
ceding Step 7.
Step 5.
From equipment interior, insert
IFP Fitting (NPT Threaded or Socket-
Weld) through clearance hole until
flange is flush against interior surface
of hood and hold in place.
Step 6.
Install one Washer and Locknut
on 1-1/2 NPS threaded portion of fitting
extending through exterior of hood.
Tighten Locknut and ensure fitting
flange is flush against interior surface
of hood.
NOTICE
To facilitate effective nozzle tighten-
ing it may be necessary to immobilize
the IFP fitting by applying appropriate
wrench to fitting wrench flats.
For proper installation ensure the
Nozzle Frame Arms are aligned per
Technical Data Sheet TFP2240.
For proper installation ensure Cap
Retention Chain is aligned with nozzle
frame arm on low side of hood slope as
applicable (Figures 3 and 4).
Step 7.
Insert the chain into the Cap
and snap cap into IFP fitting. Ensure
fitting groove is fully engaged by Cap
dimples.
