METRAFLEX SEISMIC BREAKAWAY HANGER <br /> OPERATION, INSTALLATION, AND MAINTENANCE INSTRUCTIONS <br /> General: The purpose of the Metraflex Seismic BreakAway Hanger is to support the flexible element of <br /> a seismic joint such as the Metraloop. During a seismic event, the Seismic BreakAway Hanger will <br /> break free allowing the seismic joint to freely move in its complete range of motion. After the seismic <br /> event, the Metraflex Seismic BreakAway Hanger can be simply reassembled. <br /> Application: Each Metraflex Seismic BreakAway Hanger is factory set for a specific load and will be <br /> matched to a specific Metraloop or other seismic joint. The Metraflex Seismic BreakAway Hanger is <br /> installed in the hanger rod of the seismic joint. For the Metraloop product this will be located at the <br /> 180' return fitting. For Dog Leg products this will be at the 90' elbow. For large movement units, <br /> Seismic BreakAway Hangers may be required to support the flexible hose, see figure 4 and 4A. <br /> Tethers: Tethers are used to prevent the seismic joint from over flexing and are included on all Seismic <br /> BreakAway Hangers. <br /> Installation: <br /> 1 . The Metraflex Seismic BreakAway Hanger should be installed as close to the seismic joint as <br /> possible. See figure 1 . <br /> 2. Insure that the correct size Hanger has been selected for installation by reviewing the submittal. <br /> 3. The swivel eye bolt should be installed in the top position attached to rod or cable that complies <br /> with the contract documents. See figure 1 and 2. <br /> 4. A male thread is provided for connection to the seismic joint. See figure 1 and 2. <br /> 5. Apply the no step stickers provided with the Hanger to the pipe / insulation cover. <br /> Caution: <br /> 1 . When lifting from the flexible hose, never point load the hose during the installation process, always <br /> use a saddle. The hose consists of corrugated stainless steel hose and can be damaged. <br /> 2. The Seismic BreakAway Hanger is designed for a specific load based on the size and configuration <br /> of the seismic joint. People walking on the seismic joint or other outside loads on the devise can result <br /> in premature breaking of the coupling and should be avoided. No Step warning stickers have been <br /> provided with the Seismic BreakAway Hanger for larger pipe sizes. <br /> 3. When installing a seismic joint with multiple Seismic BreakAway Hangers, evenly lift the seismic <br /> device into place. Do not over flex the hose. <br /> Testing: <br /> Each Seismic BreakAway Hanger is factory tested prior to shipment. No field testing is necessary. <br /> Maintenance: <br /> The Metraflex Seismic BreakAway Hanger does not require maintenance and there are no <br /> serviceable parts. If the Hanger is ever pulled apart, for any reason, simply insert the pin back into the <br /> Hanger until it is bottomed out. For Hangers designed to support larger seismic connections a "C- <br /> clamp" may be required to push the pin for reassembly. <br /> 2323 W.HUBBARD ST. <br /> M et ra 1(! x® TEL <br /> 2-7388-041 5 2 <br /> for pipes in motion WWW.METRAFLEX.COM <br /> C <br /> CUSTOMER: SEISMIC BREAKAWAY HANGER <br /> OPERATION,INSTALLATION,AND MAINTENANCE INSTRUCTIONS <br /> PROJECT: DRAWN BY: DKISH I DATE: I I/12/2015 <br /> APPROVED: ,JC I DATE: I I/12/2015 <br /> ENGINEER: SCALE: DRAWING NUMBER: <br /> N/A SBH-OIM 1 of 2 <br />
