VEEDER-ROOT <br />Carbon Canister Pressure Management Assembly <br />The Carbon Canister is designed in accordance with UL <br />requirement and is pending certification. <br />The unit will be installed at the UST vent pipe just below the PV <br />valve by qualified service contractors to ensure that it complies <br />with all OSHA and locally safety regulations. <br />The addition of the Carbon Canister will not constrict flow <br />through the vent stack and will not disrupt the normal operation <br />of this service station. <br />Prior to performing a TP201.3 test at the site, the manual <br />shutoff ball valve on the assembly should be moved to the <br />I <br />closed' position. After completion of the test, the valve must <br />be moved back to the 'open' position. <br />
