Product Description
The Model XL Commercial is a quick response sprinkler with
a fusible solder link thermal element designed for standard
coverage applications.
The flush style of this sprinkler conceals all operating parts
with the exception of the heat sensing link. When the solder
of the sensing link melts the operating mechanism releases
and allows the deflector to be extended for distributing water.
These sprinklers are listed for a maximum service pressure of
175 psi (12.0 bar).
Installation
Care must be exercised that orifice size, temperature rating,
and sprinkler spacing are in accordance with this bulletin
and the latest published standards of the National Fire
Protection Association, and approved by the Authority Having
Jurisdiction.
Apply a PTFE-based thread sealant or thread sealant tape to
the sprinkler threads. Using the Model ZX-Pendent or ZX-
Sidewall Wrench (see figure 2), install the sprinkler into the
fitting and verify the sprinkler is properly oriented.
Recommended installation torque is 8-14 lb-ft (11-19 N.m).
Do not tighten sprinklers over the maximum recommended
torque. Exceeding the maximum recommend torque may
cause leakage or impairment of the sprinklers.
Shipping caps should be removed only after walls are
finished and when escutcheons are being installed. Each
installed sprinkler must include an escutcheon, and only
the escutcheons shown in this bulletin shall be used with
the Model XL Commercial sprinkler. The use of any other
escutcheon will void all approvals and negate all warranties.

Maintenance
Reliable Model XL series 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.
