6.6 if the pilot and main do not ignite after the juapers have been connected <br /> for 15 minute*, it is probably because there is an air leak in the vapor <br /> piping and air is entering.as fast as it is being purged. Chech the pipe <br /> fittings, vent riser manifold® /vacuum valve, storage tank fill <br /> bko caps, <br /> dry breakgaskets and oMMr cap gaskets, hoses, bootless nozzles, <br /> and vapor valves - any place where air wild be entering the vapor. Then <br /> go���bac k to 6.4. <br /> ' 7. AWLS"IMM: <br /> The vacuum switches In the processor are adjusted and set at the factory during <br /> final funct=ial test. These settings will be satisfactory for the great <br /> majority of insta3 lations. n-,e following Nests are to see if any fine bxdng <br /> is needed to match ttp processor to the specific station on whiff you have <br /> installed it and also as an end to end system de anstratim. <br /> 7.1 Test #1: To check setting of lesser vactmsa switch <br /> 7.1.1 Condition of system for conducting test: <br /> Processor PORM IAM and' 'IAW intennittently illuminated. <br /> No customers dispensing gasoline. <br /> All product puqvOFF• <br /> All nozzles hanging on their hooks. <br /> 7.1.2 Result of test: <br /> Pressure/vacuun gage (FIGURE 4, page 13) should read between <br /> -4.2" W.C. and -4.3" W.C. If so, go to steep 7.2. If not, <br /> adjust lesser vacu= switch (FIGU2E 7,page 15) to get that reading. <br /> 7.2 Test 92: To check setting of HF vadum switch. <br /> 7.2.1 Turn off electrical power to processor. Disconnect jtsper wire <br /> between TTe�l [LO] and Terminal (23] in the pressor e s <br /> electrical panel. Removal of the jurper disconnects the main <br /> solenoid valve. Tun on electrical power to processor. <br /> 7.2.2 Cloarditiois of system for. condmting test: Sarre as 7.1.1 except <br /> one or more dispensers (product pub) 'CN. <br /> 7.2.3 Result of test: <br /> Pressure/vacLu n gage (FIGURE 4, page 3-2) should read between <br /> 4,350-W.C,. and -4.65`W.C. If so, go to step 7.2.4. If not, <br /> adjust HF va== switch (FI 7, page 15) to get that reading. <br /> 7.2.4 Turn off electrical power to processor• Reconnect myper wire <br /> bet mm Twfinal [10] and wnWnal (23] in the processor's <br /> electrical panel. Turn on electrical power to processor. <br /> 'c <br />
