<br />NOZZLES <br />-There arA twelve types of discharge nozzles each designed to dis- <br />tribute the liquid agent in a uniform pattem throughout the hazard <br />area: <br />1. 1W Nozzle 7. 245 Nozzle <br />2. 1 N Nozzle 8. 260 Nozzle <br />3. 1/2N Nozzle 9. 290 Nozzle <br />4. 3N Nozzle 10. 2120 Nozzle <br />5. 2W Nozzle 11. 1 F Nozzle <br />6. 230 Nozzle 12. 1100 Nozzle <br /> <br />Although these nozzles are similar in appearance and have <br />certain common parts, the tip of each nozzle is designed for a <br />specific application and must only be used in those areas. See <br />Nozzle Application Chart in Section IV - System Design, for <br />individual nozzle usage. <br /> <br />3/8 - 18 NPT <br />FEMALE THREAD <br /> <br />/ <br /> <br />INTERNAL CUP <br />STRAINER <br />INSIDE <br /> <br />RECESS FOR <br />BLOW OFF <br />CAP LOOP <br /> <br />NOZZLE <br />STAMPING <br /> <br /> <br />VENDOR <br />CODE <br />(IF PRESENT) <br /> <br />FIGURE 13 <br />000002 <br /> <br />Nozzle Identification Chart <br /> <br />Nozzle <br />Nozzle Nozzle Nozzle.

All are chrome-plated. The <br />swivel adaptor allows any nozzle to be rotated approximately 30. <br />in all directions. Swivel Adaptors must be ordered as a Swivel <br />Adaptor Shipping Assembly, Part No. 423572, which contains 25 <br />Swivel Adaptors. <br /> <br /> <br />FIGURE 14 <br />000003 <br /> <br />RUBBER BLOW-OFF CAPS <br /> <br />The Rubber Blow-Off Cap, Part No. 77676, help keep the orifice of <br />the nozzle free of grease or other substances that could interfere <br />with agent distribution. A retaining strap attaches the blow-off cap <br />to the nozzle. Rubber Blow-Off Caps must be ordered as a <br />Shipping Assembly, Part No. 77695, which contains 50 blow-off <br />caps, or Part No. 77411, which contains 12 blow-off caps. <br /> <br /> <br />FIGURE 15 <br />000009 <br /> <br />~ <br /> <br />METAL BLOW-OFF CAP <br /> <br />Two types of metal blow-off caps are available as options to the <br />standard rubber caps. The metal cap can be used in unusually <br />high heat conditions, generally over 400 OF (204 OC). The metal <br />blow-off cap is attached to the nozzle by means of a stainless steel <br />wire which prevents it from falling into the appliance during dis- <br />charge. Shipping Assembly Part No. 79745 contains 10 metal <br />blow-off caps for use on standard, non-swivel nozzles and <br />Shipping Assembly Part No. 415568 contains 10 metal blow-off <br />caps for use on swivel nozzles. <br /> <br />NOTICE <br />If metal blow-off caps are required for upright broil- <br />er or salamander protection, use (2) two 1 N noz- <br />zles (Part No. 419335) instead of 1/2N nozzles. <br /> <br />w <br /> <br /> <br />METAL CAP <br /> <br />FIGURE 16 <br />000152 <br />
