These limitations apply to PCI-17ABC using two nozzles (any combination of either NV-P1, NV-UF, or NV-DP). <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 Tee Cheek, Model TC-1, may be located between the cylinder and T1, and counts as two elbows in that <br />section. <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 /> <br />--.-/ <br /> <br />ULEX 3437 CEx732 <br />September 29, 1998 <br />
