In <br />7 TESTING <br />7.1 Open the ball valve marked "B" from Figure 2. The pressure measurement device <br />installed on the Test Port Assembly should now be reading UST and Clean Air <br />Separator ullage pressure (or vacuum). <br />7.2 If the station vacuum is greater than (more negative) than -2.00" wc, then proceed <br />to Section 7.2.1. If less than —2.00" wc, then proceed to Section 7.3: <br />7.2.1 Close the ball valves marked "A" and "B" from Figure 2. <br />7.2.2 Open the ball valve marked "C" from Figure 2 and wait one minute. <br />7.2.3 If necessary, use the needle valve on the Test Port Assembly to bleed air into <br />the bladder until the vacuum level reaches as close to a whole number on the <br />pressure measurement device as the accuracy of the device will provide (ie. - <br />2.00, -3.00, -4.00, -5.00, -6.00, -7.00, -8.00). Make sure the needle valve is <br />closed. Record this vacuum and start the stop watch to begin a 5 minute <br />decay. <br />7.2.4 Record the vacuum at one -minute increments up to 5 minutes. <br />7.2.5 Using the information from Table 1, verify that the vacuum after 5 minutes is <br />equal to or greater than the allowable minimum for the initial vacuum <br />recorded from Section 7.2.3. <br />7.2.6 If the vacuum is greater than the allowable minimum, the Clean Air Separator <br />passed the test. <br />7.2.7 If the vacuum is less than the allowable minimum, the Clean Air Separator <br />failed the test. <br />TABLE 1 <br />Allowable 5 Minute Vacuum Decav for Clean Air SeDarator <br />Vacuum at Start of Test <br />inches we <br />Allowable Minimum Vacuum after 5 min. <br />inches we <br />8.0 <br />5.5 <br />7.0 <br />4.7 <br />6.0 <br />3.8 <br />5.0 <br />3.0 <br />4.0 <br />2.2 <br />3.0 <br />1.5 <br />2.0 <br />0.8 <br />Healy Phase 11 EVR System Including Veeder-Root ISD, Exhibit 4 — VR -202-A <br />
