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.
