Installation

Model F4FR-NF sprinklers are intended to be installed 
in accordance with NFPA 13, FM Global Property Loss 
Prevention Data Sheets, and the requirements of applicable 
authorities having jurisdiction.

Do not install The Non-Ferrous Concealer™ in ceilings which 
have positive pressure in the space above. In addition, 
inspect all sprinklers after installation to ensure that both the 
gap between the cover plate and ceiling and the four (4) slots 
in the cup are open and free from any air flow impediment.

After a 2-5/8” diameter hole is cut in the ceiling, the sprinkler 
is installed with the Model G4 Wrench. When installing a 
sprinkler, the wrench is first positioned into the sprinkler/cup 
assembly until two wrench tangs fully engage drive slots in the 
top of the cup (there are two pairs of drive slots in the cup). 
The sprinkler is then tightened into the pipe fitting to a torque 
of 8 to18 ft-lbs (11 to 24 N

.

m).  Do not exceed the maximum 

recommended torque.  Excessive torque may cause leakage 
or impairment of the sprinkler.

When inserting or removing the wrench from the sprinkler/
cup assembly care should be taken to prevent damage to the 
sprinkler. DO NOT WRENCH ON ANY OTHER PART OF THE 
SPRINKLER/CUP ASSEMBLY.  Replace any sprinklers that 
have been damaged.

Install the cover plate by hand, pushing and then turning the 
cover in the clockwise direction until it is tight against the 
ceiling.

Maintenance

Reliable Model F4FR 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.
