ting per ANSI B16.3 or cast iron threaded tee fitting per
ANSI B16.4 with the end sprinkler fitting on a branch line
to be plugged as shown in Figure 1.
NOTE
Do not install the Luminous S170 into any other type fit-
ting without first consulting the Technical Services Depart-
ment. Failure to use the appropriate fitting may result in:
failure of the sprinkler to properly operate due to binding
of the inlet Plug; or, insufficient engagement of the inlet
pipe threads with consequent leakage.
When Dry Sprinklers are to be used in wet pipe sprinkler
systems protecting areas subject to freezing tempera-
tures (e.g., coolers or freezers), consideration must be
given to the appropriate length of the sprinkler that will
prevent freezing of the water in the connecting pipes, due
to conduction. When the temperature surrounding the wet
pipe sprinkler system is maintained at a minimum tem-
perature of 40°F/4°C, the following are the minimum rec-
ommended lengths between the face of the sprinkler fit-
ting and the outside surface of the protected area (i.e.,
length exposed to minimum ambient of 40°F/4°C):
•
12 inches (300 mm) when the temperature within the
protected area is -20°F/-29°C
•
18 inches (450 mm) when the temperature within the
protected area is -40°F/-40°C
•
24 inches (600 mm) when the temperature within the
protected area is -60°F/-51°C
For protected area temperatures between those given
above, the minimum recommended length from the face
of the fitting to the outside of the protected area may be
determined by interpolating between the indicated values.
NOTE
When Dry Sprinklers penetrate a wall into an area subject
to freezing, the clearance space around the Sprinkler
Casing must be completely sealed, in order to prevent
the leakage of moist air into the freezing area which
might result in the formation of condensate around the
Frame, Deflector, Bulb Seat, or Bulb. Failure to prevent
the formation of condensate could result in the build-up of
ice around the releasing components and, consequently,
either an inadvertent operation of the sprinkler or, im-
paired operation due to reduced thermal sensitivity.
INSTALLATION
The Luminous S178 must be installed in accordance with
the following instructions:
NOTES
The Luminous S178 must only be installed in fittings that
meet the requirements of the Design Criteria section.
Refer to the Design Criteria section for other important re-
quirements regarding sealing of the clearance space
around the Sprinkler Casing.
Do not install any bulb type sprinkler if the bulb is
