TECHNICAL DATA Pressure Ratings: Maximum allowable water working pressure is 175 psig (12 Bar) unless rated and specified for high water working pressure [250 psig (17 2 bar)] Sprinkler Identification: Viking sprinklers are identified and marked with the word"Viking", the sprinkler identification number (SIN) consisting of"VK" plus a three digit number*, the model letter and the year of manufacture Available Finishes: Viking sprinklers are available in several decorative finishes Some models are available with corrosion-resistant coatings or are fabricated from non-corrosive material Refer to the sprinkler technical data page for additional information Available Temperature Ratings: Viking sprinklers are available in several temperature ratings that relate to a specific temperature classification Applicable installa- tion rules mandate the use and limitations of each temperature classification In selecting the appropriate temperature classifica- tion, the maximum expected ceiling temperature must be known When there is doubt as to the maximum temperature at the sprinkler location a maximum-reading thermometer should be used to determine the temperature under conditions that would show the highest readings to be expected In addition, recognized installation rules may require a higher temperature classifica- tion,depending upon sprinkler location, occupancy classification, commodity classification,storage height, and other hazards In all cases,the maximum expected ceiling temperature dictates the lowest allowable temperature classification Sprinklers located immediately adjacent to a heat source may require a higher temperature rating K-Factors: Viking sprinklers are available in several orifice sizes with related K-Factors The orifice is a tapered waterway and, therefore, the K-Factor given is nominal Nominal U S K-Factors are provided in accordance with the 1999 edition of NFPA 13, Section 3-2 3 Refer to the specific data page for appropriate K-Factor information Available Styles: Viking sprinklers are available for installation in several positions as indicated by a stamping on the deflector The deflector style dictates the appropriate installation position of the sprinkler, it breaks the solid stream of water issuing from the sprinkler orifice to form a specific spray pattern The following list indicates the various styles and identification of Viking sprinklers UPRIGHT SPRINKLER:A sprinkler intended to be installed with the deflector above the frame so water flows upward through the orifice, striking the deflector and forming an umbrella-shaped spray pat- tern downward Marked"SSU"(Standard Sprinkler Upright)or"UPRIGHT" on the deflector Viking Technical Data may be found on PENDENT SPRINKLER A sprinkler intended to be oriented with the deflec- The Viking Corporation's Web site at tor below the frame so water flows downward through the orifice, striking http://www.vikinggroupinc.com. the deflector and forming an umbrella-shaped spray pattern downward The Web site may include a more recent Marked "SSP'' (Standard Sprinkler Pendent) or 'PENDENT" on the de- edition of this Technical Data Page. flector CONVENTIONAL SPRINKLER An "old style" sprinkler intended to be installed with the deflector in either the upright or pendent position The deflector provides a spherical type pattern with 40 to 60 percent of the water initially directed downward and a proportion directed upward Must be installed in accordance with installation rules for conventional or old style sprinklers DO NOT USE AS A REPLACEMENT FOR STANDARD SPRAY SPRINKLERS Marked "C U/P" (Conventional Upright/Pendent)on the deflector Form No F_080814 18 12 06 Rev 14.1 P65 Replaces Form No F_080814 Rev 14 1 (Added P65 Warning)
