1. DESCRIPTION -
STANDARD RESPONSE, QUICK RESPONSE, EXTENDED COVERAGE, AND DRY SPRINKLERS
Viking thermosensitive spray sprinklers consist of a small frame and either a glass bulb or a fusible operating element. Available
styles include pendent, flush pendent, concealed pendent, upright, horizontal sidewall, vertical sidewall, or conventional, depending
on the particular sprinkler model selected.
Viking sprinklers are available with various finishes, temperature ratings, responses, and K-Factors to meet design requirements†.
Used in conjunction with one of the corrosion-resistant coatings (for frame style sprinklers), the units provide protection against
many corrosive environments. In addition, the special Polyester or
colors are desired.
† Refer to the sprinkler technical data page for available styles, finishes, temperature ratings, responses, and nominal K-Factors for specific sprinkler models.
2. LISTINGS AND APPROVALS

4. INSTALLATION
NOTE: Take care not to over-tighten the sprinkler and/or damage its operating parts!
Maximum Torque:
1/2" NPT: 14 ft-lbs. (19.0 N-m)

1" NPT:
30 ft-lbs. (40.7 N-m)
A. 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 temperatures exceeding the maximum ambient temperature al-
lowed (refer to the temperature chart on the sprinkler technical data page). Never install any glass-bulb sprinkler if the bulb is
cracked or if there is a loss of liquid from the bulb. A small air bubble should be present in the glass bulb. Any sprinkler with a
loss of liquid from the glass bulb or damage to the fusible element should be destroyed immediately. (Note: Installing glass bulb
sprinklers in direct sunlight (ultraviolet light) may affect the color of the dye used to color code the bulb. This color change does
not affect the integrity of the bulb.)
Sprinklers must be protected from mechanical damage during storage, transport, handling, and after installation. Sprinklers subject
to mechanical damage must be protected with an approved sprinkler guard.
Use only sprinklers listed as corrosion resistant when subject to corrosive environments. When installing corrosion-resistant sprin-
klers, take care not to damage the corrosion-resistant coating. Use only the special wrench designed for installing coated or
recessed Viking sprinklers (any other wrench may damage the unit).
Concealed sprinklers must be installed in neutral or negative pressure plenums only!
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, upright, or horizontal sidewall sprinklers installed so that water is not trapped. For dry systems, pendent
sprinklers and sidewall sprinklers installed on return bends are permitted, where the sprinklers, return bend, and branch line
piping are in an area maintained at or above 40 °F (4 °C).
B. Installation Instructions - Standard Spray Sprinklers
Viking sprinklers are manufactured and tested to meet the rigid requirements of approving agencies. They 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 modification, may render them
inoperative and will automatically nullify the approvals and any guarantee made by The Viking Corporation.
