Installation
Reliable’s Model GXLO sprinkler must be installed according
to NFPA Standards or the appropriate Factory Mutual Loss Prevention Data Sheets for all area/density methods of design as
well as requirements of the Authority Having Jurisdiction.
Model GXLO sprinklers must be installed with the Reliable
Model H sprinkler wrench. Any other type of wrench may damage the sprinkler.
A leak tight joint should be obtained with a torque of 14 to
20 lb-ft (19 to 27 N-m) for ¾-inch NPT and ISO 7-R¾ thread
sprinklers. For ½-inch NPT and ISO 7-R½ thread sprinklers the
recommended installation torque is 8 to 18 lb-ft (11 to 24 N-m).
Do not tighten sprinklers over the maximum recommended installation torque, because it may cause leakage or impairment
of the sprinklers.
Model H Wrench
Use only the Model H
sprinkler wrench for sprinkler
removal and installation. Any
other type of wrench may
damage the sprinkler.
Maintenance
Model GXLO Sprinklers should be inspected and the sprinkler
system maintained in accordance with NFPA 25. Do not clean
sprinklers with soap and water, ammonia or any other cleaning
fluids. Remove dust by using a soft brush or gentle vacuuming.
Replace any sprinkler which 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.
