MSM-ZZ-QV004 Rev. 002 Step 7.2.3 Cont'd CAUTION Do NOT install a shipping protector in a holder assembly.
- a. Carefully REMOVE and DISCARD any shipping protectors furnished with rupture disc.
- b. PLACE the holder inlet on a flat surface with the alignment pins pointing up.
- c. MATCH the notches in the rupture disc with the shape of the pins.
- d. PLACE the rupture disc over the pins with the dome side down.
- e. MATCH the holes in the holder outlet with the shape of the pins in the holder inlet.
- f. POSITION the holder outlet carefully onto the alignment pins as shown; ENSURE that the rupture disc is NOT damaged.
- g. FASTEN the assembly together by tightening the pre-assembly screws or by replacing and tightening the pre-assembly cap screws.

Fastener Torque/Tightening (Q Equipment) (Prior to torque/tightening)
- l. Using a cross torquing pattern, TORQUE each nut with a calibrated torque wrench at 20% increments. Repeat 20% increments and cross torquing pattern until final torque of 65ft/lbs is achieved.
- m. REPEAT Final Torque of all nuts in rotational sequence at 65ft/lbs.
8.0 RESTORATION 8.1.1. NOTIFY Operations to perform In-Service Leak Check by separate job task. (This is to verify that no vacuum leaks at the rupture disc or the tail pipe exist as the Post Maintenance Test).
8.1.2. CLEAN the work area.
