These limilations apply to PCI'17ABC using two nozzles (any combination of, either NV-P1, NV-UF, or NV.OP). <br />2. Syslem piping must be balanced. Balanced pipIng is that in which the ditlerenc~ between the shonest actual pipe length <br />from Tl to nozzle and the longest actual pipe length Irom T1 tonozzJe does not exceed 10% of the Joncest actual pipe <br />length from Tl 'to nozzle. The number and type of fltUngstor alJ Tlto nozzle sections must be equal. <br />3.

AJI systems protQCling vehicle paint spray booths require a factory pre'set time delay. <br />5.
