<br /> <br />ACTUATION AND EXPELLENT GAS LINE REQUIREMENTS <br /> <br />(Continued) <br /> <br />Actuation Gas Line - 6 to 8* Tanks Maximum (Continued) <br /> <br />3. If an expellant gas line is connected to the regulated release <br />assembly along with an actuation gas line, the total combined <br />length of the actuation and expellant gas line must not <br />exceed 30 ft. (9 m) when using a "double-tank" nitrogen car- <br />~ tridge or a LT-A-101-3O nitrogen cartridge or a 101-30 carbon <br />.. dioxide cartridge. See Figure 72. <br /> <br />4. A combined total of nine fittings may be used in these lines, <br />eight goo elboeand one tee. Two 450 elbows equal one. <br />elbow. <br /> <br />Actuation Gas Line -10 to 15* Tanks Maximum <br />. 15 Tank maximum reflects the utilization of 3 tank regulated actuators. <br /> <br />1. Use only 1/4 in. Schedule 40 black iron, hot-dipped galva- <br />nized, chrome-plated, or stainless steel pipe and fittings. <br />NOTE: Stainless steel hose and fittings can also be used.

The total leng1h of the actuation gas line from the remote <br />mechanical release to the regulated actuator assemblies must <br />not exceed 100 ft. (30.5 m). <br /> <br />3. A combined total of 20 elbows and 9 tees may be used <br />in these lines. Two 450 elbows equal one goo elbow. See <br />.. Figure 73. <br /> <br />~ 4. Use only a 101-10 carbon dioxide cartridge in the 101 remote <br />mechanical release. <br /> <br />5. A safety vent relief valve (Part No. 15677) is required in the <br />actuation gas line to relieve residual pressure after actuation. <br /> <br />REGULATED <br />ACTUATOR <br />ASSEMBLY <br /> <br />~ <br /> <br />REGULATED ACTUATOR <br />ASSEMBLY EXPELLANT GAS LINES <br />NOT INCLUDED IN COMBINED TOTALS <br /> <br />FIGURE 72 <br />00<l2<2 <br /> <br />9 TEES MAXIMUM <br /> <br />20 ELBOWS <br />MAXIMUM <br /> <br /> <br />II _ <br />II[ r" <br />11,0 <br />l)~ <br />I I <br />I I <br />I' <br />'-' <br /> <br />AGENT TANK <br /> <br />MAXIMUM OF FIVE <br />REGULATED ACTUATORS <br /> <br />t <br /> <br />REMOTE RELEASE <br />MECHANISMS <br />(PART NO. 32381) <br />5 MAXIMUM <br /> <br />FIGURE 73 <br />000301 <br />
