• -5- • <br /> 6.4 Use the flow meter to determine the nitrogen regulator delivery pressures that <br /> correspond to nitrogen flow rates of 2.0 CFM (120 CFH) and 4.0 CFM (240 CFH). <br /> These pressures define the allowable range of delivery pressures acceptable <br /> for this test procedure. The flow meter shall be connected in-line between the <br /> nitrogen supply regulator and the Test Port Assembly during pressurization. The <br /> flow meter may be connected in-line between the nitrogen supply regulator and <br /> the Test Port Assembly during the test. <br /> 6.5 The electronic pressure measurement device shall be subject to warm-up and <br /> drift check before use; see Section 4.5. <br /> 6.6 The four ball valves used in the installation of the Clean Air Separator are <br /> lockable and shall be locked in the position shown in Figure 213-2 or 2B-2H of <br /> Exhibit 2 and in Figure 1 or Figure 1 H of this Exhibit during normal operation. <br /> Figure 1 and 26-2 apply to vertical CAS installations and Figure 1 H and 28- <br /> 2H apply to horizontal CAS installations. The four padlocks provided by Healy <br /> Systems, Inc. in their installation kit are keyed the same. However, it is possible <br /> that one or more of the padlocks on the Clean Air Separator could have been <br /> replaced (seizing, damage, broken key, etc.). Conducting this test will require a <br /> set of keys necessary to unlock all padlocks. <br /> 6.7 Verify that the Clean Air Separator is in its normal operating configuration by <br /> confirming that all components are as indicated (See Figure 1 or Figure 1 H): <br /> Valve "A" - Open <br /> Valve "B, C and D" - Closed <br /> Pipe End "E" - Plugged <br /> Tee Branch "F" - Plugged <br /> Healy Clean Air Separator Test Procedure, Exhibit 4—Executive Orders VR-201-D and VR-202-D <br />
