Installation
Do not install The 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 4 slots in the
cup are open and free from any air flow impediment.
After a 2
5
8
²
diameter hole is cut in the ceiling, the sprin-
kler is to be installed with the Model G4 Wrench. When in-
stalling a sprinkler, the wrench is first positioned into the
sprinkler/cup assembly until two wrench tangs fully en-
gage 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. 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.
The equipment presented in this bulletin is to be installed in accordance with the latest pertinent Standards of the National Fire Protection Association, Factory Mutual Research
Corporation, or other similar organizations and also with the provisions of governmental codes or ordinances whenever applicable.

:
The adjustable inlet versions are similar to the standard
Model F4FR except that an additional 1
²
of adjustment is
provided by means of a telescoping inlet section that
threads in or out of a stationary coupling reducer (either 1
²
NPT male or 1
²
NPT female) as shown in Figures 2 or 3.
These sprinklers must be installed, before the ceiling is in
place by wrenching on only the coupling reducer hex
flats. After the ceiling has been installed, each telescoping
inlet section is to be adjusted with the G4 Wrench. Final
adjustment of each cover is made by hand turning the
cover in the clockwise direction until it is tight against the
ceiling. THE MODEL F4FR CONCEALER MUST BE IN-
STALLED ONLY WITH A 135°F RATED COVER.
Maintenance
The Model F4FR should be inspected quarterly 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 any sprinkler that
has been painted (other than factory applied) or dam-
aged in any way. A stock of spare sprinklers should be
maintained to allow quick replacement of damaged or op-
erated sprinklers. Prior to installation, sprinklers should be
maintained in the original cartons and packaging to mini-
mize the potential for damage to sprinklers that would
cause improper operation or non-operation.
