  • Page 5  Read these instructions carefully and completely before attempting to unpack, install or service the bursting disc and holder.  Do not vent a bursting disc assembly to an area where it would endanger personnel.  Install the bursting disc assembly in such a way that equipment in the area will not prevent bursting disc from opening or be damaged by system discharge.
  • Page 6 WARNING: Always handle the bursting disc with extreme caution. Nicks, dents, scratches or foreign material may result in leakage or affect the burst pressure. Read the bursting disc tag completely before installing to confirm that the size and type are correct for your system. 1.
  • Page 7 Figure 2 - Insert holder (top) and pre-torqueable holder 1. For insert style holders, carefully remove the bursting disc assembly from piping. 2. Separate bursting disc holder components. 3. Remove old bursting disc. 4. Inspect the seat area of the bursting disc holder. Look for scratches, nicks, corrosion or deposits left from the media.
  • Page 8 Note: Use of an o-ring is for improved sealing and is not required for proper function of the bursting disc assembly. Do not install an o-ring unless the holder is designed to accept these components by Fike! 3. Place bursting disc into holder component with female seat with flow arrow on tag pointing in the same direction as holder component with female seat flow arrow.
  • Page 9 5. Carefully align and place holder component with male seat onto rupture disc with flow arrow in the same direction as disc and holder component with female seat flow arrows. CAUTION: Be careful to not allow the male seat component to strike or damage the dome of the rupture disc! Figure 5 - Alignment pin fitting in tag slot (Atlas sizes 14"...
  • Page 10 Figure 6 - Pretorquaeble Holder (TQ+/TQ(+) Full Torque Configuration Shown) 10. Check gap between base and hold down. The gap must be the same size on all sides of the assembly. This can be assured by measuring the distance between the hold down and base at various places around the circumference of the assembly.
  • Page 11 Atlas holders 14” and larger require a spool piece if under a pressure relief valve. Refer to Fike Technical Bulletin TB8105 for code requirements. WARNING: Double check the orientation of the bursting disc. Verify flow arrows on the holder and disc tag are pointed in the same direction as process flow.
