3. PRODUCT DESCRIPTION
Viking quick response sprinklers are
thermosensitive spray sprinklers con-
sisting of a small frame and either a
glass bulb or a fusible operating ele-
ment that meets the criteria for quick
response. Available styles include pen-
dent, flush pendent, concealed pendent,
concealed sidewall, upright, horizontal
sidewall, flush horizontal sidewall, verti-
cal sidewall, or conventional (old style).
Quick response sprinklers are avail-
able with various finishes, temperature
ratings, and K-Factors to meet design
requirements†.
† Refer to the appropriate sprinkler technical
data page for available styles, finishes,
temperature ratings, and nominal K-Factors
for specific sprinkler models.
4. TECHNICAL DATA
Refer to the appropriate sprinkler tech-
nical data page for listing and approval
information and technical information on
sprinkler materials and accessories.
5. CARE AND HANDLING
(Also refer to Bulletin - Care and Handling of
Sprinklers, Form No. F_091699.)
Sprinklers must be handled with care.
They must be stored in a cool, dry
place in their original shipping container.
Never install sprinklers that have been
dropped, damaged, or exposed to tem-
peratures exceeding the maximum am-
bient temperature allowed. Never install
any glass-bulb sprinkler if the bulb is
cracked or if there is a loss of liquid from
the bulb. Any sprinkler with a loss of
liquid from the glass bulb or damage to
the fusible element should be destroyed
immediately.
Sprinklers must be protected from me-
chanical damage. Sprinklers subject to
mechanical damage must be protected
with an approved sprinkler guard.
Use only sprinklers listed as corrosion
resistant when subject to corrosive en-
vironments. When installing corrosion-
resistant sprinklers, take care not to
damage the corrosion-resistant coating.
Note: Units of measure in parentheses may be approximations.
Form No. F_011500
TECHNICAL DATA
Use only the special wrench designed
for installing coated and recessed Viking
-
sprinklers (any other wrench may dam-
age the unit).
Use care when locating sprinklers near
fixtures that can generate heat. Do
not install sprinklers where they could
be exposed to temperatures exceeding
the maximum recommended ambient
temperature for the temperature rating
used.
Wet-pipe systems must be provided
with adequate heat. Sprinklers supplied
from dry systems in areas subject to
freezing must be listed dry sprinklers, or
upright or horizontal sidewall sprinklers
installed so that water is not trapped.
For dry systems, pendent sprinklers
and sidewall sprinklers installed on re-
turn bends are permitted, where the
sprinklers, return bend, and branch line
piping are in an area maintained at or
above 40 °F (4 °C).
6. INSTALLATION
For Institutional Flush Style
Sprinklers, refer to the appropriate
institutional sprinkler technical data
page for installation instructions.
WARNING: Viking sprinklers are manu-
factured and tested to meet the rigid re-
quirements of approving agencies. The
sprinklers are designed to be installed in
accordance with recognized installation
standards. Deviation from the standards
or any alteration to sprinklers or cover
plate assemblies after they leave the
factory including, but not limited to:
painting, plating, coating, or modifica-
tion, may render them inoperative and
will automatically nullify the approvals
and any guarantee made by Viking.
Viking sprinklers are to be installed
in accordance with the latest edi-
tion of Viking technical data, the
latest standards of NFPA, FM Global,
LPCB, Assemblee Pleniere, VdS or
other similar organizations, and also
with the provisions of governmental
codes, ordinances, and standards,
whenever applicable. The sprinkler
technical data page may contain
installation requirements specific
for the sprinkler model selected.
The use of quick response sprinklers
may be limited due to occupancy
and hazard. Refer to the Authority
Having Jurisdiction prior to installa-
tion. NOTE: QR concealed sprinklers
must be installed in neutral or nega-
tive pressure plenums only.
Before installation, be sure to have the
Replaces page QR1-2, dated Jan. 16, 2006 (updated for new con-
cealed sprinklers). Refer to the appropriate sprinkler technical
data page for detailed information on specific sprinkler models.

appropriate sprinkler model and style,
with the correct orifice size, temperature
rating, and response characteristics.
Sprinklers must be installed after the
piping is in place to prevent mechanical
damage. Keep sprinklers with protective
caps or bulb shields contained within
the caps or shields during installation
and testing, and any time the sprinkler
is shipped or handled.
A1. For frame-style sprinklers, install es-
cutcheon (if used), which is designed
to thread onto the external threads of
the sprinkler.*
* Refer to the appropriate sprinkler data page
to determine approved escutcheons.
A2. For quick response flush and
concealed style sprinklers: Cut the
sprinkler nipple so that the ½" or 3/4"
(15 mm or 20 mm)** NPT outlet of the
reducing coupling is at the desired lo-
cation, and centered in the opening**
in the ceiling or wall.
**Size depends on the sprinkler model used.
Refer to appropriate sprinkler data page.
B. Apply a small amount of pipe-joint
compound or tape to the external
threads of the sprinkler only, taking
care not to allow a build-up of com-
pound in the sprinkler inlet.
NOTE: Sprinklers with protective caps or
bulb shields must be contained within
the caps or shields before applying pipe-
joint compound or tape. Exception: For
concealed sprinklers VK302, VK352,
VK462, VK463, and VK464, remove
the protective cap for installation.
C. Refer to the appropriate sprinkler
technical data page to determine the
correct sprinkler wrench for the model
of sprinkler used. DO NOT use the
deflector or fusible element to start or
thread the sprinkler into a fitting.
Install the sprinkler onto the piping
using the special sprinkler wrench
only, taking care not to over-tighten or
damage the sprinkler operating parts.
For flush and concealed style sprin-
klers: the internal diameter of the
special sprinkler installation wrench
is designed for use with the sprinkler
contained within the protective shell.
Exception: For concealed sprinklers
VK302, VK352, VK462, VK463, and
VK464, remove the protective cap for
installation, and then place it back on
the sprinkler temporarily. Thread the
quick response flush or concealed
sprinkler into the ½" or 3/4" (15 mm
or 20 mm)†† NPT outlet of the cou-
pling by turning it clockwise with the
special sprinkler wrench.
††Thread size depends on the particular
