Chapter a—System Design <br /> Pago-3 10--- <br /> REV.3 <br /> PCI-17ABC with 2 nozzles <br /> • <br /> TANK • <br /> T1 <br /> NOZZLE i <br /> 002863PC <br /> Maximum Length Elbows <br /> Cylinder Size Nozzle Quantity Nozzle Type Piping Section Size Maximum Maximum <br /> PCI-17ABC 2 NV-UF, or any Cylinder to T1 3/4 in. 36 ft 7 <br /> combination of NV-PI (10.9 m) <br /> (See Note 5), <br /> NV-DP2, N-PLU <br /> T1 to Nozzle 3/4 in. 14 ft (4.3 m) 4 <br /> NOTE: <br /> ► 1. These limitations apply to PCI-17ABC using two nozzles (any combination of either NV-P1, NV-DP2, or N-PLU). <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. All systems protecting vehicle paint spray booths require a factory pre-set time delay. <br /> 5. When using an NV-P1 nozzle, the two largest discharge orifices in the nozzle body must be positioned parallel to the <br /> longest dimension of the hazard being protected. <br /> 6. Maximum height of nozzle from base of tank to nozzle—20 ft(6.1 m). <br /> • <br /> ULEX 3437 CEx732 I 9 /0 <br /> February 1,2010 d <br />
