The Models NV-P1 and NV-D/P2 must be located on branch T2A to nozzle only. <br /> <br />NOTE: <br />1. These limitations apply to PCI-70ABC using four NV-WA nozzles. <br />2. System piping must be balanced. Balanced piping is that in which the difference between the shortest actual pipe length <br />from last tee to nozzle and the longest actual pipe length from last tee to nozzle does not exceed 10% of the longest <br />actual pipe length from last tee to nozzle. The number and type of fittings for all last tee to nozzle sections must be <br />equal. <br />3. A Main/Reserve Tee Check, 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. .J <br /> <br />---./ <br /> <br />LEX 3437 CEx732 <br />~ptember 29, 1998 <br />
