' Pressure Sensor Installation Vapor Vent Stack/nstaddadon Step 19. Install one 68CA-4-4 male connector (item 1 in Table 3) onto the top of the new pipe (see View A-A, Figure 6). 20. Measure,fabricate, and install 1/4" OD copper tubing (item 6 in Table 3) between the bulkhead union and the male connector. Adjust the enclosure vertically on vent pipe to make sure the copper tube is fully inserted into ' the bulk head union and male connector. 21. Fully tighten the compression nuts to secure the fabricated tube to the bulkhead union and to the male connector.Tighten the enclosure mounting hardware to secure the enclosure in its final vertical position. Note: Important!All plumbing's pitch to drain should be 1/4"vertical per 12" horizontal to eliminate any potential liquid traps. 22. Make sure the valve's handle is set to connect the sensor to the vapor vent stack as shown in Figure 7 and ' not to the capped (vent) port. 23. Install two tamper-resistant screws from the enclosure hardware bag into the two holes on the enclosure door (if not already installed) using a Torx bit for tamper-resistant screws. Discard any remaining items in the enclosure hardware bag. 24. When direct wiring to a TLS console, install 1/2" electrical conduit from the conduit hub in the bottom of the enclosure to the customer supplied weather-proof junction box (see Figure 6). For wireless installations, using the TLS RF, Steps 23 - 27 are not required. 25. Route the cable from the pressure sensor to the junction box under the enclosure. Observing polarity, connect the sensor wiring to the field wiring from console and cap with wire nuts (see Figure 6). 26. Seal wire nuts in epoxy sealant following the instructions in Figure 4. 27. Push the epoxy sealed bag into the junction box. Replace and tighten the junction box cover. 28. Terminate field wiring into TLS Console and connect to Smart Sensor Module (TLS console - Figure 5). Note: observe polarity! The cable length between the console and sensor must not exceed the distance stated in the TLS-3XX Site Prep manual (P/N 576013-879).\ 29. After the Pressure Sensor is installed, pressurize the tank ullage space and vapor piping to at least 2 inches WC and test for leaks using leak detection solution. 30. Close the enclosure door and secure by threading the tamper-resistant screws into the enclosure body using a Torx bit for tamper-resistant screws. 31. Affix the eVRgreen label (item 4 in Table 4) to the enclosure door as desired. JAN 1. ��.-tom ` ° ." •e 14
