” inch (67mm) diameter hole is cut in the ceiling, the
sprinkler is easily installed with the Model FC Wrench. The
wrench has a socket drive which is inserted into the body of
the sprinkler. When installing a sprinkler the wrench is first
positioned into the sprinkler/cup assembly until the wrench
socket engages the body of the sprinkler. The sprinkler is
then tightened into the pipe fitting. When inserting or remov-
ing 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. Install the cover plate by hand turning the
cover in the clockwise direction until it is tight against the ceil-
ing.
A protective cap is provided to protect the drop-down sprinkler
deflector from damage which could occur during construction
before the cover plate is installed. The cap is factory installed
inside the sprinkler cup. Remove cap to install sprinkler, then re-
install cap until the cover plate is installed.
Maintenance
The Model G5-56, G5-42 and G5-28 should be inspected
quarterly and the sprinkler system maintained in accordance
with NFPA 25. Do not clean sprinklers with soap and water, am-
monia or any other cleaning fluids. Remove any sprinkler that
has been painted (other than factory applied) or damaged in
any way. Concealed sprinklers cover plates can not be painted
in the field, after installation or have any other coating applied
other than the factory finish. A stock of spare sprinklers should
be maintained to allow quick replacement of damaged or oper-
ated sprinklers. Prior to installation, sprinklers should be main-
tained in the original cartons and packaging to minimize the
potential for damage to sprinklers that would cause improper
operation or non-operation.
