Chapter 3 — System Design <br /> Page 3 -8 <br /> REV. 2 <br /> PCI- 25sABC with 2 Nozzles <br /> ( <br /> CYLINDER III <br /> T1 <br /> ■ NOZZLE ■ <br /> 002863PC <br /> ► Maximum Length Elbows Length Elbows <br /> Cylinder Size Nozzle Quantity Nozzle Type Piping Section Size Maximum Maximum Minimum Minimum <br /> PCI- 25sABC 2 N -LA -ABC Cylinder to T1 3/4 in. 28 ft. 5 5 ft. 1 <br /> (8.5 m) (1.5 m) <br /> T1 to Nozzle 3/4 in. 25 ft. 4 2.5 ft. 1 <br /> ► (7.6 m) (.8 m) <br /> Total Cylinder 53 ft. 9 25 ft. 4 <br /> ► to Nozzle (16.2 m) (7.8 m) <br /> NOTE: <br /> 1. These limitations apply to PCI- 25sABC using two N -LA -ABC nozzles. <br /> 2. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length <br /> from T1 to nozzle and the longest actual pipe length from T1 to nozzle does not exceed 10% of the longest actual pipe <br /> length from T1 to nozzle. The number and type of fittings for all T1 to nozzle sections must be equal. <br /> 3. A Main /Reserve Swing Check Valve, Part No. 417788, may be located between the cylinder and T1. <br /> 4. Minimum requirements for piping and fittings do not apply to systems protecting hazards with no splashable hazard. A <br /> splashable hazard exists where liquid fuel in depth greater than 1/4 in. is present. <br /> ULEX 3437 CEx732 <br /> September 1, 2006 <br />
