B. Refer to the appropriate sprinkler technical data page to determine the correct sprinkler wrench for the model of sprinkler used. C. Install the dry sprinkler on the piping using the special dry sprinkler wrench only, while taking care not to damage the sprinkler. NOTE: Thread the sprinkler into the fitting hand tight, plus 1/2 turn with the dry sprinkler wrench. D. For adjustable standard and adjustable recessed dry pendent and sidewall sprinklers: Escutcheons can be installed after the sprinklers have been installed onto the piping. Refer to the appropriate sprinkler technical data page for escutcheon installation instructions and illustrations. D. Installation Instructions-Testing 4.After installation, the entire sprinkler system must be tested. The test must be conducted to comply with the installation stand- ards.Viking high pressure sprinklers may be hydrostatically tested at a maximum of 300 psi(20.7 bar)for limited periods of time (two hours), for the purpose of acceptance by the Authority Having Jurisdiction. a. Make sure the sprinkler is properly tightened. If a thread leak occurs, normally the sprinkler 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.Air testing [do not exceed 40 psi (2.76 bar)]the sprinkler piping prior to testing with water may be considered in areas where leakage during testing must be prevented. Refer to the Installation Standards and the Authority Having Jurisdiction. b. Remove plastic protective sprinkler caps or bulb shields AFTER the wall or ceiling finish work is completed where the sprinkler is installed and there no longer is a potential for mechanical damage to the sprinkler operating ele- ments. To remove the bulb shields, simply pull the ends of the shields apart where they are snapped together. To remove caps from frame style sprinklers, turn the caps slightly and pull them off the sprinklers. SPRINKLER CAPS OR BULB SHIELDS MUST BE REMOVED FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE! Retain a protective cap or shield in the spare sprinkler cabinet. 5. For flush style sprinklers: the ceiling ring can now be installed onto the sprinkler body. Align the ceiling ring with the sprinkler body and thread or push it on (depends on sprinkler model) until the outer flange touches the surface of the ceiling. Note the maximum adjustment is 1/4" (6.35 mm). DO NOT MODIFY THE UNIT. If necessary, re-cut the sprinkler drop nipple as required. 6. For concealed sprinklers: the cover assembly can now be attached. a. Remove the cover from the protective box, taking care not to damage the cover plate assembly. b. Gently place the base of the cover plate assembly over the sprinkler protruding through the opening in the ceiling. c. Push the cover plate assembly onto the sprinkler until the unfinished brass flange of the cover plate base (or the cover adapter, if used)touches the surface of the ceiling. d. Refer to the applicable technical data sheet to determin the maximum adjustment available for concealed sprinklers. DO NOT MODIFY THE UNIT. If necessary, re-cut the sprinkler drop nipple. NOTE: If it is necessary to remove the entire sprinkler unit,the system must be taken out of service.See section 6. INSPECTIONS, TESTS AND MAINTENANCE and follow all warnings and instructions. 5. OPERATION Refer to the appropriate sprinkler technical data page(s). During fire conditions,the operating element fuses or shatters(depending on the type of sprinkler), releasing the pip cap and sealing assembly.Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern to extinguish or control the fire. IMPORTANT. Always refer to Bulletin Form No. F_091699 - Care and Handling of Sprinklers. Viking sprinklers are to be installed in accordance with the latest edition of Viking technical data, the appro- priate standards of NFPA, FM Global, LPCB, APSAD, VdS or other similar organizations, and also with the provisions of governmental codes, ordinances, and standards, whenever applicable. The sprinkler technical data page may contain installation requirements specific for the sprinkler model selected. The use of certain types of sprinklers may be limited due to occupancy and hazard. Refer to the Authority Having Jurisdiction prior to installation. Form No. F_080614 18.10.11 Rev 16.1.P65
