Model HL22 (SIN RA1011)
K22.4 (320 metric)
Early Suppression
Fast Response (ESFR) Sprinkler
Product Description
The Reliable Model HL22 is an Early Suppression Fast
Response (ESFR) Sprinkler with a nominal k-factor of
22.4 (320 metric). This sprinkler is designed to respond
quickly to growing fires with a high volume of water
discharge to “suppress” rather than “control” fires.
FM Global classifies the Model HL22 as a quick-
response sprinkler, storage and non-storage, when the
sprinkler is used in accordance with FM Global Property
Loss Prevention Data Sheets.
The Model HL22 sprinkler utilizes a levered fusible
alloy solder link in either 165°F (74°C) or 212°F (100°C)
temperature rating. The sprinkler has a nominal K Factor
of 22.4 (metric 320), and is available with 1” NPT or
ISO 7-R1 threads, or with the Victaulic® IGS™ Style V9
Sprinkler Coupling*.
Application and Installation
The HL22 ESFR sprinkler is intended for installation
in accordance with NFPA 13 and Factory Mutual (FM)
Loss Prevention Data Sheets 2-0 and 8-9, as well as
the requirements of any Authorities Having Jurisdiction.
See Table 1 for information on NFPA and FM Global
design criteria for the Model HL22 sprinkler.
In addition to design criteria permitted by NFPA
13, the Model HL22 also has the following Specific
Application Listing from UL, as documented in Table C:
• Sprinkler: Model HL22 in 212°F (100°C) only
• Maximum Ceiling Height: 48 ft. (14.6 m)
• Maximum Storage Height: 43 ft. (13.1 m)
• Minimum Aisle Width: 8 ft. (2.44 m)
• Permitted Commodities: Class I - IV commodities,
encapsulated or nonencapsulated, and Cartoned
Group A Unexpanded plastics. Permitted
Storage Arrangements: Single- and double-row
rack storage (no open top containers or solid
shelves) and palletized and solid pile storage
(no open top containers or solid shelves).
• Minimum System Operating
Pressure: 55 psi (3.79 bar).
• Installation and Obstruction Criteria: Same as
for K25.2 ESFR sprinklers, but with a maximum
deflector to ceiling distance of 14 in. (356 mm)
Follow installation criteria in NFPA 13 or FM Global
Property Loss Prevention Data Sheets. For installations
using the UL Listed Specific Application Criteria for
ceiling heights up to 48 ft. (14.6 m), also follow the
additional installation criteria contained in this bulletin.

Installation
For threaded sprinklers, use only the Model W5
sprinkler wrench. Any other type of wrench may
damage the sprinkler. Sprinklers should be tightened
between 22 - 30 ft-lbs (30 - 41 Nm) torque. Sprinklers
not tightened to recommended torque or tightened past
recommended torque may cause leakage or impairment
of the sprinkler. Damaged sprinklers must be replaced
immediately.
For grooved sprinklers, push the IGS™ Style V9
Sprinkler Coupling onto the grooved outlet until contact
with the center leg of the gasket occurs. Align the
sprinkler frame arms and the pads of the coupling with
the sprinkler piping and tighten the coupling until the
pads of the coupling meet. For additional information,
please reference Victaulic technical bulletin I-V9.
Caution: When handling sprinklers, hold sprinklers only
by the frame arms and do not apply any force on the link
assembly.
Maintenance
The Model HL22 ESFR Sprinkler should be inspected
and the sprinkler system maintained in accordance with
NFPA 25. Do not clean sprinkler with soap and water,
ammonia or any other cleaning fluid. Remove any
sprinkler that has been painted (other than factory applied)

or damaged in any way. A stock of spare sprinklers
should be maintained to allow quick replacement of
damaged or operated sprinklers. Prior to installation,
sprinklers should be maintained in the original cartons
and packaging until used, to minimize the potential
for damage to sprinklers that would cause improper
operation or non-operation.
Once operated, automatic sprinklers cannot be
reassembled and reused. New sprinklers of the same
size, type and temperature rating must be installed. A
cabinet of replacement sprinklers should be provided for
this purpose.
