<br />Chepler 3 - System Design <br />Page 3-14 <br />REV. 3 <br /> <br />Fryer - Multiple Nozzle ProtectIon <br /> <br />Fryers exceeding the coverage of a single nDzzle CBn be <br />divided Into modules. Each module musl nol exceed Ihe <br />maximum area allowed for a single nozzle. However, when <br />ulillzlng multiple nozzle prolectlDn, the longest side allowed <br />for a fryer wllh drip board can be used, regardless of <br />whether the fryer has a drip board or not. <br /> <br />The maximum size fryer that can be modularized Is 864 sq. <br />in. (5574 sq. cm). <br /> <br />Design requirements for multiple nozzle fryers are broken <br />down as follDWS: <br /> <br />1. If Ihe fryer Includes any drlpboard areas, measure both <br />the internallenglh (front (0 back) and width Df Ihe frypot <br />portion. Then measure the Internallenglh and width of <br />Ihe overall hazard area IncludIng any drlpboard arees. <br /> <br />Determine the area of both the frypot and the area of the <br />overall val by mulliplylng corresponding lenglh and width <br />dimensIons. <br /> <br />2. Divide (he frypol or ova rail vatlnlo modules, each Dr <br />which can be protected by a sIngle nDzzle, based on Ihe <br />maximum dImension and area coverage Df the nDzzle as <br />specIfied in "Design CherI." <br /> <br />If the module considered does nollnc/ude any pDrllDn <br />of lhe drlpboard, use only the maxImum frypot erea <br />end maximum dimension listed In the "Design Chart: <br /> <br />If the module considered Includes any drlpbDard <br />areas, use bolh lhe maximum frypol area and dlmBn- <br />sian lis led In the "Design Chart", and the maximum. <br />overall area and dimension listed In lhe "Design <br />Chart." <br /> <br />3. None of the maximum dimenslDns mey be exceeded. II <br />either (he maximum frypot.or the overall sizes ere <br />exceeded, Ihe area divided Inlo modules will need 10 be <br />redefined wllh Ihe posslbl/Jly of an add/Ilona I nDzzle. <br /> <br />ULEX 3830 <br />August 1, 2005 <br /> <br />PN551274(3) <br /> <br />PIPING LIMITATIONS <br /> <br />Once the nozzle placemenl and quantity of tanks has been <br />delermlned, Ills necessary 10 delermlne Ihe piping configu- <br />rallons between lhe lenk and the nDzzles.
