Product Description
The Reliable Model HL22 is an Early Suppression
Fast Response (ESFR) Sprinkler with a nominal K-factor of 22.4
(320 metric). The sprinklers use a levered fusible alloy solder
link in either a 165°F (74°C) or a 212°F (100°C) temperature
rating. These sprinklers are designed to respond quickly
to growing fires and will deliver a heavy water discharge to
“suppress” rather than “control” fires.
FM Approvals classifies the Model HL22 as a quick-response
sprinkler, storage and non-storage, when used in accordance
with FM Global Property Loss Prevention Data Sheets.
In addition to the design criteria provided in NFPA 13, the Model
HL22 also has a Specific Application UL listing for 45’ storage
of Class I - IV and cartoned unexpanded Group A plastic in a
48’ building (reference Table C for full details).
The HL22 sprinklers are available with 1” NPT or ISO7 R-1
threads, and also with the Victaulic® IGS™ Style V9 Sprinkler
Coupling*.

Installation
Model HL22 sprinklers are intended for installation in
accordance with NFPA 13 and FM Loss Prevention Data Sheets
2-0 and 8-9, as well as the requirements of any Authorities
Having Jurisdiction. See Table B for information on NFPA and
FM Global design criteria for the Model HL22 sprinklers.
For threaded sprinklers only, use the Model W5 sprinkler
wrench for removal and installation (Figure 3). Any other type of
wrench may damage the sprinkler. A grooved wrench boss is
provided on the sprinkler to limit the potential for the wrench to
slip during installation.
Model HL22 sprinklers should be tightened between 14 - 40
lbs-ft (19 - 54 N.m) torque. Do not tighten sprinklers over the
maximum recommended torque. Exceeding the maximum
recommended torque may cause leakage or impairment of the
sprinklers.
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.
Damaged sprinklers must be replaced immediately.
Maintenance
Reliable Model HL22 sprinklers should be inspected and the
sprinkler system maintained in accordance with NFPA
25, as well as the requirements of any Authorities Having
Jurisdiction.
Prior to installation, sprinklers should remain in the original
cartons and packaging until used. This will minimize the
potential for damage to sprinklers that could cause improper
operation or non-operation.
Do not clean sprinklers with soap and water, ammonia liquid or
any other cleaning fluids. Remove dust by gentle vacuuming
without touching the sprinkler.
Replace any sprinkler which has been painted (other than
factory applied). A stock of spare sprinklers should be
maintained to allow quick replacement of damaged or operated
sprinklers.
Failure to properly maintain sprinklers may result in inadvertent
operation or non-operation during a fire event.
