Mounting Pressure Sensor Assembly onto Composite Panel <br /> 21. Make sure the valve's handle is set to connect the sensor to the vapor vent stack and not to the capped <br /> (ambient) port. <br /> 22. Install two tamper-resistant screws from the enclosure hardware bag into the two holes on the enclosure <br /> door (if not already installed) using a Torx bit for tamper-resistant screws. Discard any remaining items in the <br /> enclosure hardware bag. <br /> 23. When direct wiring to a TLS console, install 1/2" electrical conduit from the conduit hub in the bottom of the <br /> enclosure to the customer supplied weather-proof junction box (see Figure 10). For wireless installations, <br /> using the TLS RF, Steps 23 - 27 are not required. <br /> 24. Route the cable from the pressure sensor to the junction box under the enclosure. Observing polarity, <br /> connect the sensor wiring to the field wiring from console and cap with wire nuts (see Figure 10). <br /> 25. Seal wire nuts in epoxy sealant following the instructions in Figure 8. <br /> 26. Push the epoxy sealed bag into the junction box. Replace and tighten the junction box cover. <br /> 10-16 <br /> CARB Approved IOM 10-Veeder Root Pressure Sensor-Executive Order VR-202 <br />
