Reliable GXLO Series Manual

Model GXLO Series Sprinklers
Upright with Factory Installed Shield
Upright Pendent
Product Description
Reliable Model GXLO (extra-large orifice) upright and
pendent sprinklers are standard coverage, standard
response sprinklers that utilize a robust center strut, solder in
compression thermal element. These sprinklers are intended
for use in hydraulically calculated control mode density area
(CMDA) storage and non-storage occupancies in accordance
with the area/density curves of NFPA 13 or other applicable
standards.
The Model GXLO sprinkler is FM Approved as a standard
response storage and non-storage sprinkler when used in
accordance with FM Global Property Loss Prevention Data
Sheets.
For new installations, the sprinkler is provided with either 3/4-
inch NPT or ISO 7-R3/4 threads. The upright version is also
available with 1/2-inch NPT or ISO 7-R1/2 threads for retrofit
installations only. Sprinklers without guards are installed using
the Model H wrench.
For use as an intermediate level sprinkler, the Model GXLO
upright sprinkler is available with a factory installed water
shield. Various other water shields, guards, or guard/shield
options are also available for both upright and pendent
models (please refer to Technical Specifications on following
pages). Sprinkler guards or guard/shields may be installed
in the field or factory installed. Use of the Model JV sprinkler
wrench is required for installation where a guard is added to
the sprinkler prior to threading the assembly into a fitting.

Installation
Model GXLO sprinklers must be installed according to appropriate
NFPA Standards, FM Global Loss Prevention Data Sheets, and/or
the requirements of the authority having jurisdiction.
Use only the Model H sprinkler wrench for sprinkler installation
or use the Model JV wrench to install the sprinkler/guard
assembly (Figure 3). Any other type of wrench may damage
the sprinkler. Damaged sprinklers must be replaced
immediately.
A leak tight joint should be obtained with a torque of 14 to 20
lb-ft (19 to 27 N.m) for 3/4 inch NPT and ISO 7-R3/4 thread
sprinklers. For 1/2 inch NPT and ISO 7-R1/2 thread sprinklers the
recommended installation torque is 8 to 18 lb-ft (11 to 24 N.m).
Exceeding the maximum recommended torque may cause leakage
or impairment of the sprinklers.
Maintenance
Reliable Model GXLO 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.
