FLAT SPRAY PENDENT
SPRINKLERS VK920 (K80)
AND VK922 (K115)
4. INSTALLATION
The sprinklers are designed to be installed in accordance with recognized installation standards. Viking Flat Spray Pendent
Sprinklers must be installed in accordance with the latest edition of Viking technical data, CEA 4001 “Sprinkler Systems Planning
and Installation” or EN12845 “Automatic Sprinkler Systems - Design, Installation, and Maintenance”, the Authorities Having
Jurisdiction, and also with the provisions of governmental codes, ordinances, and standards whenever applicable. Deviation from
the standards or any alteration to the sprinkler after it leaves the factory including, but not limited to: painting, plating, coating, or
modification, may render the sprinkler inoperative and will automatically nullify the approval and any guarantee made by The Viking
Corporation.
A. 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 or damaged in any way or exposed to temperatures exceeding the maximum ambient tem-
perature allowed (refer to Table 1). 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 should be
destroyed immediately.
B. Wet pipe systems must be provided with adequate heat.
C. 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.

The sprinkler temperature rating is stamped on the deflector.

Sprinklers shall be chosen with a temperature rating close to but not lower than 30 °C above the highest anticipated ambient temperature.
Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having Jurisdiction. Refer to
specific installation standards.

D. The sprinklers must be installed after the piping is in place to
prevent mechanical damage. Before installing, be sure to have
the appropriate sprinkler model and style, with the correct orifice
size, temperature rating, and response characteristics.
E. With the sprinkler contained in the plastic protective shield,
apply a small amount of pipe-joint compound or tape to the male
threads only, while taking care not to allow a build-up of com-
pound in the sprinkler orifice.
F. Install the sprinkler on the piping using special sprinkler wrench
10896W/B only, while taking care not to damage the sprinkler
operating parts. (Any other type of wrench may damage the unit.)
DO NOT use the sprinkler deflector to start or thread the sprinkler
into a fitting.
G. After installation, the entire sprinkler system must be tested. The
test must be conducted to comply with the Installation Standards.
Make sure the sprinkler has been properly tightened. If a thread
leak occurs, normally the unit must be removed, new pipe-joint
compound or tape applied, and then reinstalled. This is due to the
fact that when the joint seal is damaged, the sealing compound or
tape is washed out of the joint. Immediately replace any damaged
units, using the special sprinkler wrench only.
