IMPORTANT
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 Model ESFR-17 Dry Type
Pendent Sprinklers (TY7229) are “Early
Suppression Fast Response Sprin-
klers” having a nominal K-factor of 16.8.
They are suppression mode sprinklers
that are especially advantageous as a
means of eliminating in-rack sprinklers
when protecting high-piled box-in-box
refrigerated storage areas.
The Model ESFR-17 Dry Type Sprinkler
consists of an ESFR sprinkler per-
manently secured to a sprinkler drop
featuring an inlet with both grooved
and threaded connections. The drop
between the inlet and sprinkler remains
dry until the sprinkler operates,
allowing for a pendent sprinkler instal-
lation on a wet pipe sprinkler system
where the dry drop and sprinkler are
located in an area subjected to freezing
temperatures.
The Model ESFR-17 Dry Type Sprin-
klers are primarily used for ceiling only
sprinkler protection (i.e., no need for
in-rack sprinklers) and used to protect
solid piled, palletized, and rack storage
that is subject to freezing tempera-
tures. The water supply is provided
from a wet pipe system located outside
of the refrigerated storage area. The
Model ESFR-17 Dry Type Sprinklers
feature all of the same design criteria
as 16.8 K-factor ESFR Pendent Sprin-
klers, and substantially lowers the
end head pressure requirement as
compared to the 14.0 K-factor ESFR
Dry Type Pendent Sprinklers.
Combining a 16.8 K-factor with a
dry type sprinkler design, the Model
ESFR-17 Dry Type Sprinklers provides
the system designer with features that
offer exibility when sizing system
piping, as well as possibly reducing or
eliminating the need for a system re
pump when protecting high-piled box-
in-box refrigerated storage areas.
The ESFR-17 Dry Type Sprinkler also
includes two Insulating Seal Assem-
blies to seal the top and the bottom
of the clearance space where the
sprinkler drop protrudes through the
cold storage ceiling.
NOTICE
The Model ESFR-17 Dry Type Pendent
Sprinklers (TY7229) 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, in
addition to the standards of any author-
ities having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted with
any questions.

Sprinkler Threaded Fittings
1-1/4 inch NPT Model ESFR-17 Dry
Type Sprinklers are to be installed in
the 1-1/4 inch NPT outlet or run of the
following ttings:
• Malleable or ductile iron threaded
tee tting that meet the dimensional
requirements of ANSI B16.3 (Class
150).
• Cast iron threaded tee ttings that
meet the dimensional requirements
of ANSI B16.4 (Class 125).
Do not install Model ESFR-17 Dry Type
Sprinkler into elbow ttings. The inlet
of the sprinkler can contact the inte-
rior of the elbow and result in damage
to the assembly, resulting in leakage
The Model ESFR-17 Dry Type Sprin-
kler can also be installed in the 1-1/4
inch NPT outlet of a GRINNELL Figure
730 Mechanical Tee.
Sprinkler Grooved Connection
The Model ESFR-17 Dry Type Sprin-
klers can be installed in typical
grooved connection scenarios illus-
trated in Figure 7.
For exible couplings, use of the 2
Inch Figure 705 GRINNELL Flexible
Couplings with “C” Shape Pre-Lu-
bricated Grade “A” EPDM Gasket
(Technical Data Sheet 110) is
recommended.
For rigid couplings, use of the 2
Inch, Figure 577 GRINNELL G-FIRE
Grooved Rigid Coupling with “C”
Shape Pre-Lubricated Grade “A”
EPDM Gasket (Technical Data Sheet
TFP1854) is recommended.
When using tees, use of the Figure
219 GRINNELL Grooved Ductile Iron
Cast Fittings (Technical Data Sheet
TFP1810) is recommended.
NOTICE
Do not install Model ESFR-17 Dry Type
Sprinkler into any other type fitting
connection without first consulting
the Technical Services Department.
Failure to use the appropriate fitting
may result in insufficient engagement
of the inlet pipe threads with conse-
quent leakage.
Exposure Length
When using Model ESFR-17 Dry Type
Sprinklers to protect areas subject to
freezing temperatures, use Figures 3
and 4 to determine a sprinkler’s ap-
propriate exposed barrel length to
prevent water from freezing in the
connection pipes due to conduction.
The exposed barrel length measure-
ment must be taken from the face
of the sprinkler tting to the exterior
surface of the structure or insulation
that is exposed to the heated area.
Do not attempt to add additional insu-
lation around the barrel in the heated
area as a method to minimize conden-
sation. This will reduce the calculated
“Exposure Length”.
Clearance Space
In accordance with Section 8.4.9.2
of the 2010 edition of NFPA 13, when
protecting insulated freezer structures
with dry type sprinklers, the clearance
hole around the sprinkler barrel of the
Dry Type Sprinkler and the clearance
hole must be sealed. Sealing is ac-
complished by use of the Insulating
Seal Assemblies (Figure 6).Failure to
use the Insulating Seal Assemblies will
increase the potential for the formation
of condensation on the sprinkler and
subsequent ice build-up on or around
the sprinkler can occur that might
damage the dry type sprinkler and/
or prevent proper operation in a re
situation.
Operation
The casing between the inlet and the
sprinkler remains dry until the sprinkler
operates. The fusible link assembly
is comprised of two link halves that
are joined together by a thin layer
of solder. When the rated tempera-
ture is reached, the solder melts and
the two link halves separate, activat-
ing the sprinkler and allowing water
to ow through the casing and to the
activated sprinkler.

COMMODITY SELECTION AND DESIGN CRITERIA OVERVIEW
Installation
The TYCO Model ESFR-17 Dry Type
Pendent Sprinklers (TY7229) must
be installed in accordance with this
section.
General Instructions
Avoid damage to the fusible Link
Assembly during installation by using
only the Casing to handle the sprinkler
(that is, do not apply pressure to the
fusible Link Assembly), and by using
the appropriate sprinkler wrench.
Failure to do so can lead to an
unstable link assembly and premature
activation of the sprinkler. Damaged
sprinklers must be replaced.
Model ESFR-17 Dry Type Sprinklers
must only be installed in ttings/con-
nections that meet the requirements
of the Design Criteria section. Refer
to the Design Criteria section for other
important requirements regarding
piping design, exposure length, and
the sealing of the clearance space
around the sprinkler casing.
If a sprinkler using a threaded connec-
tion (vs. grooved connection) requires
replacement, remove the sprinkler
using only the W-Type 26 Sprinkler
Wrench. Fully engage the wrench
on the Inlet Wrench Hex (Figure
2). Replace with the new sprinkler
following the installation instructions
in this section.
Threaded Connection Instructions
A leak-tight 1-1/4 inch NPT sprinkler
joint should be obtained by applying a
minimum-to-maximum torque of 45 to
65 ft.-lbs. (61 to 88 Nm). Higher levels
of torque can distort the sprinkler inlet
with consequent leakage or impair-
ment of the sprinkler.
Step 1. Apply a non-hardening pipe-
thread sealant such as TEFLON to the
Male 1-1/4 inch NPT Inlet threads.
Step 2. Install the Model ESFR-17 Dry
Type Pendent Sprinkler in the pendent
position (Figure 3) by carefully raising
the pendent sprinkler through the
clearance hole. The deector of the
pendent sprinkler is to be parallel to
the ceiling.
Step 3. Wrench-tighten the Model
ESFR-17 Dry Type Sprinkler using
only the W-Type 26 Sprinkler Wrench
(Figure 2) and by fully engaging the
wrench on the inlet wrench hex (Figure
2). For reference, the FRAME ARMS
marking can be used to align with the
frame arms with the System Pipe as
shown in Figure 5.
Step 4. After installation, inspect the
Link Assembly of each Model ESFR-17
Dry Type Sprinkler for damage. In par-
ticular, verify that the Link Assembly
and Hook are positioned as illustrated
in Figure 1, and that the Link Assembly
is not bent, creased, or forced out of
normal position in any way. Replace
damaged sprinklers.
Step 5. Install the Insulation Rings
of the Insulating Seal Assemblies by
slipping the Insulation Rings around
the sprinkler casing as shown in
Figure 6. Place the Inserts over
the Insulation Rings by sliding the
Inserts around the casing. Place the
Housings over the Inserts and Insu-
lation Rings ensuring that the slot on
the Housings are 180 degrees to the
Inserts slot. Ensure that the Insulating
Seal Assemblies are snug against the
refrigerated storage ceiling. Secure
the Insulating Seal Assemblies to the
ceiling using two self-tapping screws
per assembly.
Grooved Connection Instructions
The following instructions are based
on using the 2 Inch Figure 705
Grooved Flexible Coupling or the
2 Inch Figure 577 Grooved Rigid
Coupling.
Step 1. Inspect the exterior groove
and the end connection of the
mating grooved connection and
sprinkler to verify all burrs, loose
debris, dirt, chips, paint and other
foreign materials such as grease are
removed. Sealing surfaces must be
free from sharp edges, projections,
indentations, and/or other defects.
Step 2. Verify that the coupling and
gasket grade are correct for the ap-
plication intended. Refer to Technical
Data Sheet TFP1895 for additional
gasket information. The sealing edges
and the outer surfaces of the gasket
should be covered with a ne layer
of lubricant. To prevent deteriora-
tion of the gasket material, a silicone
lubricant should be used to prevent
freezing of the lubricant.
Step 3. Install the Model ESFR-17 Dry
Type Pendent Sprinkler in the pendent
position (Figures 4 and 7) by carefully
raising the pendent sprinkler through
the clearance hole. The deector of
the pendent sprinkler is to be parallel
to the ceiling. Also, ensure that the
“FRAME ARMS” markings on the
sprinkler casing are aligned with the
System Pipe. (See Figure 5).
Step 4. Install the gasket by placing it
over the sealing portion of the grooved
inlet connection so that the gasket lip
does not extend beyond the end of
the groove sealing surface. Bring end
of the grooved inlet together with end
of grooved tting ensuring vertical
and horizontal alignment. Slide the
gasket over both sealing surfaces.

TFP320
Page 5 of 8
Step 5. With one bolt and nut
removed, separate the coupling
housings and place over the gasket.
Verify that the coupling housings are
over the gasket and that the coupling
housing keys are fully engaged into
the grooves.
Step 6. Insert the bolt and nut into the
coupling and nger tighten both nuts.
Verify that the bolt heads are fully
recessed in the housing.
The 2 Inch Figure 705 Grooved
Flexible Coupling Housing bolt pads
must be in metal to metal contact.
For Flexible Coupling deection data,
refer to Technical Data Sheet G110.
The 2 Inch Figure 577 Grooved Rigid
Coupling has an intended gap of up
to 1/16 of an inch at each pad to allow
for positive rigid gripping onto the
pipe. The patented tongue and groove
design provides protection to the
back of the gasket during installation.
Step 7. Alternate between both sides
of the coupling when tightening the
bolts. Torque bolts to 30 ft.-lbs (41
Nm).
Step 8. Install the Insulation Rings
of the Insulating Seal Assemblies by
slipping the Insulation Rings around
the sprinkler casing as shown in
Figure 6. Place the Inserts over
the Insulation Rings by sliding the
Inserts around the casing. Place the
Housings over the Inserts and Insu-
lation Rings ensuring that the slot on
the Housings is 180 degrees to the
Inserts slot. Ensure that the Insulating
Seal Assemblies are snug against the
refrigerated storage ceiling. Secure
the Insulating Seal Assemblies to the
ceiling using two self-tapping screws
per assembly.
Care and
Maintenance
The TYCO Model ESFR-17 Dry Type
Pendent Sprinklers (TY7229) must
be maintained and serviced in accor-
dance with this section.
Before closing a re protection system
main control valve for maintenance
work on the re protection system
that it controls, obtain permission to
shut down the affected re protection
from the proper authorities and notify
all personnel who may be affected by
this action.
Sprinklers which are found to be
leaking or exhibiting visible signs of
corrosion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory.
Modied or overheated sprinklers
must be replaced.
A Vent Hole is provided in the Link
Assembly Button (Figure 1) to indicate
if the Dry Sprinkler is remaining dry.
Evidence of leakage from the Vent
Hole indicates potential leakage past
the Inlet seal and the need to remove
the sprinkler to determine the cause of
leakage; for example, an improper in-
stallation or an ice plug. Close the re
protection system control valve and
drain the system before removing the
sprinkler.
When replacing a sprinkler, remove
and discard the old Insulating Seal
Assemblies and replace as shown in
Figure 6.
Care must be exercised to avoid
damage to the sprinklers - before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like,
must be replaced.
The owner is responsible for the
inspection, testing, and mainte-
nance of their re 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 25), in addition to the
standards of any authorities having
jurisdiction. Contact the installing
contractor or sprinkler manufacturer
regarding any questions.
Automatic sprinkler systems are
recommended to be inspected,
tested, and maintained by a qualied
Inspection Service in accordance with
local requirements and/or national
codes.
