DESCRIPTION - STANDARD RESPONSE, QUICK RESPONSE, EXTENDED COVERAGE,AND DRY SPRINKLERS <br /> Viking thermosensitive spray sprinklers consist of a small frame and either a glass bulb or a fusible operating element.Available <br /> styles include pendent,flush pendent,concealed pendent, upright, horizontal sidewall,vertical sidewall,or conventional,depending <br /> on the particular sprinkler model selected. <br /> Viking sprinklers are available with various finishes, temperature ratings, responses, and K-Factors to meet design requirementst. <br /> Used in conjunction with one of the corrosion-resistant coatings (for frame style sprinklers), the units provide protection against <br /> many corrosive environments. In addition, the special Polyester or Teflon°coatings can be used in decorative applications where <br /> colors are desired. <br /> t Refer to the sprinkler technical data page for available styles,finishes,temperature ratings,responses,and nominal K-Factors for specific sprinkler models. <br /> 2. LISTINGS AND APPROVALS <br /> Refer to the Approval Charts on the appropriate sprinkler technical data page(s)and/or approval agency listings. <br /> 3. TECHNICAL DATA <br /> Specifications: <br /> EWARNING:Cancer and Reproductive Harm- <br /> Refer to the appropriate sprinkler technical data sheet. www.P65Warnings.ca.gov <br /> Material Standards: <br /> Refer to the appropriate sprinkler technical data sheet. <br /> 4. INSTALLATION <br /> NOTE: Take care not to over-tighten the sprinkler and/or damage its operating parts! <br /> Maximum Torque: <br /> 1/2" NPT: 14 ft-lbs. (19.0 N-m) <br /> 3/4" NPT: 20 ft-lbs. (27.1 N-m) <br /> 1" NPT. 30 ft-lbs. (40.7 N-m) <br /> A. Care and Handling (also refer to Bulletin -Care and Handling of Sprinklers, Form No. F_091699.) <br /> Sprinklers must be handled with care. They must be stored in a cool, dry place in their original shipping container. Never install <br /> sprinklers that have been dropped, damaged, or exposed to temperatures exceeding the maximum ambient temperature al- <br /> lowed (refer to the temperature chart on the sprinkler technical data page). Never install any glass-bulb sprinkler if the bulb is <br /> 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 <br /> loss of liquid from the glass bulb or damage to the fusible element should be destroyed immediately. (Note: Installing glass bulb <br /> sprinklers in direct sunlight(ultraviolet light) may affect the color of the dye used to color code the bulb.This color change does <br /> not affect the integrity of the bulb.) <br /> Sprinklers must be protected from mechanical damage during storage,transport, handling, and after installation.Sprinklers subject <br /> to mechanical damage must be protected with an approved sprinkler guard. <br /> Use only sprinklers listed as corrosion resistant when subject to corrosive environments.When installing corrosion-resistant sprin- <br /> klers, take care not to damage the corrosion-resistant coating. Use only the special wrench designed for installing coated or <br /> recessed Viking sprinklers (any other wrench may damage the unit). <br /> Concealed sprinklers must be installed in neutral or negative pressure plenums only! <br /> Use care when locating sprinklers near fixtures that can generate heat. Do not install sprinklers where they could be exposed to <br /> temperatures exceeding the maximum recommended ambient temperature for the temperature rating used. <br /> Wet pipe systems must be provided with adequate heat. Sprinklers supplied from dry systems in areas subject to freezing must <br /> be listed dry sprinklers, upright, or horizontal sidewall sprinklers installed so that water is not trapped. For dry systems, pendent <br /> sprinklers and sidewall sprinklers installed on return bends are permitted, where the sprinklers, return bend, and branch line <br /> piping are in an area maintained at or above 40 °F (4 °C). <br /> B. Installation Instructions-Standard Spray Sprinklers <br /> Viking sprinklers are manufactured and tested to meet the rigid requirements of approving agencies. They are designed to be <br /> installed in accordance with recognized installation standards. Deviation from the standards or any alteration to sprinklers or cover <br /> plate assemblies after they leave the factory including, but not limited to: painting, plating,coating,or modification, may render them <br /> inoperative and will automatically nullify the approvals and any guarantee made by The Viking Corporation. <br /> Form No. F_080614 18.10.11 Rev 16.1.P65 Replaces Form No. F_080614 Rev 16.1 <br /> (Added P65 Warning.) <br />
