11 <br />All tanks must be measured to determine vertical deflection. Follow deflectioiHneasurement instructions in the Installation Manual. An initial deflection <br />measurement is taken and recorded as a point of reference. Subsequent measurements show tank deflection and can be compared to the Table below. Take <br />each measurement from the same fitting using the same procedure. <br />ridn 11ridMP II <br />TANK <br />XERXES& *TANK INSTALLATION CH&LIST <br />CORPORATION <br />Fiberglass Underground Storage Tanks <br />DIAMETER <br />Single -Wall (SWT), Double -Wall (DWT), Multicompartment (MCT) and OilMater Separators (OWS) <br />6 <br />8 <br />10 <br />12 <br />Complete this checklist, and keep it with copies of any written authorizations for variations and/or deviations received from Xerxes. <br />• <br />Date of Installation Tank Size and Capacity <br />• <br />Tank Type SWT DINT MONITORING -FLUID DRY MCT OWS (Circle those that apply.)
