<br />4. INSTALLATION
<br />
<br />WARNING: Viking sprinklers are manufactured and tested to meet rigid requirements of the approving agency. The sprinklers are
<br />designed to be installed in accordance with recognized installation standards. System design must be based on ESFR design
<br />guidelines described in the latest edition of Viking technical data, applicable FM Giol,ql Loss Prevention Data Sheets, the latest
<br />NFPA Standards, the latest standards of Verband der Sachversicherer (VdS), Loss Prevention Council (LPCB), the Authorities
<br />Having Jurisdiction, and also with the provisions of governmental codes, ordinances, and standards whenever applicable, Deviation
<br />from the standards or any alteration to the sprinkler after it leaves the factory including, but not limited to: painting, plating, coating,
<br />or modification, may render the sprinkler inoperative and will automatically nullify the approval and any guarantee made by The
<br />Viking Corporation.
<br />
<br />A. 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 or damaged in any way, Such sprinklers should be destroyed immediately. NOTE: Wet pipe
<br />systems must be provided with adequate heat.
<br />
<br />B. The sprinklers must be installed after the piping is in place to prevent mechanical damage. Before installing, be sure to have the
<br />appropriate sprinkler model and style, with the correct orifice size, temperature rating, and response characteristics.
<br />
<br />C. With the sprinkler contained in the plastic protective cap, apply a small amount of pipe-joint compound or tape to the male threads
<br />only, while taking care not to allow a build-up of compound in the sprinkler orifice.
<br />
<br />0, Use ONLY sprinkler wrench 10285W/B or 13635W/B (shown in Figure 1) for installing ESFR Sprinkler VK500! With the
<br />sprinkler contained in the protective cap, install the sprinkler onto the piping by applying the sprinkler wrench to the
<br />sprinkler wrench flats only, while taking care not to damage the sprinkler operating parts.
<br />
<br />. DO NOT use any other -type of wrench, as this could damage the unit.
<br />
<br />. DO NOT use the sprinkler deflector or fusible element to start or thread the sprinkler into a fitting.
<br />
<br />. DO NOT exceed 50 ft. Ibs. of torque (hand tight, plus approximately two full turns with the wrench) to install these sprinklers.
<br />Higher levels of torque may distort the sprinkler inlet with consequent leakage or impairment of the sprinkler.
<br />
<br />E, After installation, the entire sprinkler system must be tested, The test must be conducted to comply with the Installation Standards.
<br />Make sure the sprinkler has been properly tightened. If a thread leak occurs, normally the unit must be removed, new pipe-joint
<br />compound or tape applied, and then reinstalled, This is due to the fact that when the joint seal is damaged, the sealing compound
<br />or tape is washed out of the joint. Immediately replace any damaged units, using the special sprinkler wrench only.
<br />
<br />F, After installation and testing and repairing of all leaks, remove the protective caps from the sprinklers. Do NOT use any
<br />type of tool to remove the cap. Remove the cap by hand: turn it slightly and pull it off the sprinkler. When removing caps,
<br />use care to prevent dislodging or damaging sprinkler ejector spring and fusible element. THE CAPS MUST BE REMOVED
<br />FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN SERVICE!
<br />
<br />G. System design must be based on ESFR design guidelines described in applicable FM Global Loss Prevention Data Sheets, the latest
<br />standards of Verband der Sachversicherer, LPCB, the National Fire Protection Association, and the Authorities Having Jurisdiction.
<br />All requirements of recognized sprinkler system design standards apply to systems utilizing Viking ESFR Pendent Sprinklers.
<br />NOTE: Viking recommends installing one style of sprinklers (either pendent or upright) throughout ESFR systems.
<br />However, provided the fusible elements are installed within the distance below the ceiling allowed by the installation
<br />standards, and when acceptable to the Authority Having Jurisdiction, Viking considers the practice of mixing upright
<br />and pendent ESFR sprinklers to be acceptable.
<br />
<br />5. OPERATION
<br />During fire conditions, the heat-sensitive fusible element assembly disengages, releasing the seat and spring assemblies to open the
<br />waterway, Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattem to suppress the fire,
