Order ESFR Upright Sprinkler VK520 by first adding the appropriate suffix for the sprinkler finish and then the appropriate suffix for 

the temperature rating to sprinkler base part number.

Finish Suffix: Brass = A

Temperature Suffix: 165 °F (74 °C) = C, 205 °F (96 °C) = E

For example, sprinkler 10625 with a Brass finish and a 165 °F (74 °C) temperature rating = Part No. 10625AC.

4.  INSTALLATION

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 in excess of the maximum ambient tempera-

ture allowed. 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. 

NOTE: No 

sprig is required for sprinkler pipe sizes up to and including 3” (76.2 mm) nominal O.D.

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 05118CW/B (shown in Figure 1) for installing ESFR Sprinkler VK520! 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.

•  DO NOT exceed 50 ft. lbs. of torque (hand tight, plus approximately two full turns with the wrench) to install these sprinklers. 

Higher levels of torque may distort the sprinkler inlet with consequent leakage or impairment 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 removing 

caps, use care to prevent dislodging or damaging sprinkler ejector spring and fusible element. THE CAPS MUST BE 

REMOVED FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE!

WARNING

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 or FM Global Loss Prevention Data 

Sheets. System design must be based on ESFR design guidelines described in the latest edition of the applicable FM 

Global Loss Prevention Data Sheets, the latest NFPA Standards, the latest standards of Verband der Sachversicherer 

(VdS), Loss Prevention Council (LPCB), the Authorities Having Jurisdiction, and also with the provisions of govern

-

mental 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.
