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.
