1. DESCRIPTION
Viking Specific Application Early Suppression Fast Response (ESFR) Pendent
Sprinkler VK514 incorporates the capability to suppress specific high-challenge fires.
The addition of a larger K-Factor allows protection of higher hazard commodities at
greater ceiling heights with lower end-head pressures. K28.0 ESFR sprinklers can:
• Eliminate the use of in-rack sprinklers when protecting high-piled storage of certain
specified materials up to 43 ft. (13.1 m) with ceilings up to 48 ft. (14.6 m)*
• Reduce or eliminate the need for a system fire pump.
• Provide flexibility when sizing system piping.
Viking VK514 ESFR Pendent Sprinklers are primarily intended to protect the following
types of storage, which tend to produce severe-challenge fires: palletized and solid
pile storage and single, double, and portable open rack storage (no open-top contain-
ers or solid shelves). The VK514 is listed to utilize a minimum aisle width of 6’-0”.
Viking ESFR Pendent VK514 Sprinklers provide protection of most common storage
materials, including:
• Encapsulated or unencapsulated Class I, II, III, and IV commodities*.
• UL Listed for protection of cartoned non-expanded plastic commodities*.
* Refer the Approval Charts and Design Criteria for UL Listing requirements that must be followed.

4. INSTALLATION
Viking sprinklers are manufactured and tested to meet rigid requirements of the approving agencies. The sprinklers
are designed to be installed in accordance with recognized installation standards. System design must be based on ESFR design
guidelines described in the latest NFPA Standards, the Authorities Having Jurisdiction, and also with the provisions of governmen-
tal 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. Such sprinklers should be destroyed immediately. NOTE: Wet pipe
systems must be provided with adequate heat.
B. 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.
C. With the sprinkler contained in the plastic protective cap, 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 compound in the sprinkler orifice.
D. Use ONLY sprinkler wrench 13635W/B (shown in Figure 1) for installing VK514! With the sprinkler contained in the
protective cap, install the sprinkler onto the piping by applying the sprinkler wrench to the sprinkler wrench flats only,
while taking care not to damage the sprinkler operating parts.
• DO NOT use any other type of wrench, as this could damage the unit.
• DO NOT use the sprinkler deflector or fusible element to start or thread the sprinkler into a fitting.
• Hand tight plus 1 to 1-1/2 turns with wrench. Over tightening may distort the sprinkler inlet with consequent leakage or impair-
ment of the sprinkler.
E. 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.
F. After installation and testing and repairing of all leaks, remove the protective caps from the sprinklers. Do NOT use
any type of tool to remove the cap. Remove the cap by hand: turn it slightly and pull it off the sprinkler. When remov-
ing caps, use care to prevent dislodging or damaging sprinkler fusible element. THE CAPS MUST BE REMOVED FROM
SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE!

5. OPERATION
During fire conditions, the heat-sensitive fusible element assembly disengages, releasing the seat and belleville spring assembly
to open the waterway. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern to
suppress the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
The owner is responsible for maintaining the fire protection system and devices in proper operating condition. For
minimum maintenance and inspection requirements, refer to the NFPA standard that describes care and maintenance of sprinkler
systems. In addition, the Authorities Having Jurisdiction may have additional maintenance, testing, and inspection requirements
that must be followed.
A. The sprinklers must be inspected on a regular basis for corrosion, mechanical damage, obstructions, paint, etc. The frequency of
inspections may vary due to corrosive atmosphere, water supplies, and activity around the device.
B. Sprinklers that have been painted or mechanically damaged must be replaced immediately. Sprinklers showing signs of corrosion
shall be tested and/or replaced immediately as required. Installation standards require sprinklers to be tested and, if necessary, re-
placed after a specified term of service. For Viking Specific Application ESFR Pendent Sprinklers, refer to the Installation Standards
and the Authorities Having Jurisdiction for the specified period of time after which testing and/or replacement is required. Sprinklers
that have operated cannot be reassembled or reused, but must be replaced. When replacing sprinklers, use only new sprinklers.
C. The sprinkler discharge pattern is critical for proper fire protection. Therefore, nothing should be hung from, attached to, or other-
wise obstruct the discharge pattern. All obstructions must be immediately removed or, if necessary, additional sprinklers installed.
D. When replacing existing sprinklers, the system must be removed from service. Refer to the appropriate system description and/
or valve instructions. Prior to removing the system from service, notify all Authorities Having Jurisdiction. Consideration should be
given to employment of a fire patrol in the affected area.
1. Remove the system from service, drain all water, and relieve all pressure on the piping.
2. Using the special sprinkler wrench, remove the old sprinkler and install the new unit. Care must be taken to ensure that the
replacement sprinkler is the proper model and style, with the correct orifice size, temperature rating, and response character-
istics. A fully stocked spare sprinkler cabinet should be provided for this purpose.
3. Place the system back in service and secure all valves. Check the replaced sprinklers and repair all leaks.
E. Sprinkler systems that have been subject to a fire must be returned to service as soon as possible. The entire system must
be inspected for damage and repaired or replaced as necessary. Sprinklers that have been exposed to corrosive products of
combustion, but have not operated, should be replaced. Refer to the Authorities Having Jurisdiction for minimum replacement
requirements.
