Model FC <br />For use with Model G5 Series sprinklers <br />without wrench -able cap installed <br />Fully insert the Model W3 wrench over the cap until it reaches <br />the bottom of the cup, or the Model FC wrench over the sprinkler <br />until the wrench engages the body. Do not wrench any other <br />part of the sprinkler/cup assembly. The Model W3 and FC <br />wrenches are designed to be turned with a standard 1/2" square <br />drive. Tighten the sprinkler into the fitting after applying a PTFE <br />based thread sealant to the sprinkler's threads. Recommended <br />installation torque is specified in Table J. <br />Installation Torque <br />Recommended Installation <br />Sprinkler Threads Torque (min. — max.) <br />ft.lb I N•m <br />'/z" NPT or ISO7-1 R1/2 8-18 11-24 <br />3/4" NPT or ISO7-1 R3/4 14-20 19-27 <br />Do not exceed the maximum recommended torque. Exceeding the <br />maximum recommended torque may cause leakage or impairment <br />of the sprinkler. Use care when inserting or removing the wrench <br />from the sprinkler to avoid damage to the sprinkler. <br />Install the cover plate by hand, pushing and then turning the cover <br />in the clockwise direction until it is tight against the ceiling. For <br />Model G5 QR Gasket and Model G5 SR Gasket cover plates, the <br />gasket should be attached to the flange of the cover plate skirt <br />only. Do not glue the gasket in place or allow the gasket to overlap <br />both the cover plate and the flange of the skirt. <br />Maintenance <br />Reliable Model G5 series sprinkler should be inspected and the <br />sprinkler system maintained in accordance with NFPA 25, as well <br />as the requirements of any Authorities Having Jurisdiction. <br />Prior to installation, sprinklers should remain in the original cartons <br />and packaging until used. This will minimize the potential for <br />damage to sprinklers that could cause improper operation or non - <br />operation. <br />Do not clean sprinklers with soap and water, ammonia liquid or any <br />other cleaning fluids. Remove dust by gentle vacuuming without <br />touching the sprinkler. <br />Am <br />Model W3 <br />For use with Model G5 Series sprinklers with <br />wrench -able cap installed <br />Replace any sprinkler or cover plate which has been painted (other <br />than factory applied). Properly installed Model G5 cover plates will <br />have an air gap that is required for proper operation, do not seal <br />the gap or paint the cover plates. Model G5 series sprinklers have <br />holes in the cup that must remain unobstructed. <br />Replace any sprinkler which has been damaged. A stock of spare <br />sprinklers should be maintained to allow quick re -placement <br />of damaged or operated sprinklers. Failure to properly maintain <br />sprinklers may result in inadvertent operation or non -operation <br />during a fire event. <br />Guarantee <br />For the Reliable Automatic Sprinkler Co., Inc. guarantee, terms, <br />and conditions, visit www.reliablesprinkler.com. <br />Patents <br />Model G5 series sprinklers may be covered by one or more of the <br />following patents: <br />U.S. Patent 6,554,077, U.S. Patent 7,275,603, U.S. Patent <br />8,776,903, U.S. Patent 9,248,327 <br />Ordering Information <br />Specify the following when ordering. <br />Sprinkler <br />• Model [G5-28] [G5-42] [G5-56] [G5-56 300] <br />[G5-80] [G5-80F] <br />• Temperature Rating [165°F (74°C)] [212°F (100°C)] <br />• Threads [NPT or ISO 7-1] <br />Cover Plate <br />• Model [G5, G5 QR Gasket, G5 SR Gasket] <br />• Finish (See Table 1) <br />Sprinkler Wrench <br />• Model W3 <br />• Model FC <br />G <br />1 <br />Bulletin 034 <br />April 2023 <br />Page 9 of 9 <br />www.reliablesprinkler.com <br />
