In this case, the hood may not .axceed a length of 6 ft. for <br />the ADP noale and 10 R f orthe plenuni noule. The hood shall <br />not exceed a width ot 6 ft. for either noale. <br />A single tilter bank plenum wfth a length of 6 ft. or less may <br />be protected by one ADP noale. A"V" f iftcr bank plenum with <br />a length of 3 ft or less may also be protected by one ADP <br />noale. A plenumwith either a sirgle tiRerbank or"V" fitterbank <br />and a lenglh of 10 ft. or less may be protected by one plenum <br />noale. Eilher noale shall be located at one end of the plenum. <br />Longer plenums may be similarly protected with a single ADP <br />noale being used for each 3 or 6 ft of plenum length (depend- <br />iny on the type of filter bank) and each 10 ft. of plenum length <br />for pienum nozzles. <br />ADP and plenum noules may be used in�combinations <br />(see Figure 19d). Muftiples may be installed in pairs at the <br />midpoint of the plenum with their discharges directed at the <br />ends of the plenum or installed at each end of the plenum with <br />the discharges directed at the midpoint. <br />ADP and pienum noules must be centrally (see figure 20d) <br />located in the plenum with their discharge directed along the <br />length of the plenum. in no case, however, shall the horizontal <br />center line ot the noules be located more than 15 inches from <br />the inside fiRer surface. <br />'Y" FILTEA BANK <br />Upro9' � <br />Vptoe' � . <br />Up to 10' � <br />'12' <br />t0'-1'tat3 _�. ���. <br />1 O'-1' to 16 <br />13'-t' to 16' : r.,:Q'..; ��; <br />16'd' to 20' � � <br />• .:�., V :i'�1 I 20'-1'to30�� j .l.':� ��i:-iil I <br />PLENUM OR AOP NOmE CENTCRm IN G�ENUM P{,pNUM OR ADP 1i0m!
