Figure 4 - Sealable Cover Model Height Adjustment <br /> Operation and Maintenance : <br /> Annually : Inspect and clean the interior of the spill <br /> container and drain valve screen . Remove <br /> accumulated dirt and grit . Test the drain valve using <br /> CARB procedure TP -201 . 1 C or TP-201 . 1 D . If the <br /> drain valve passes testing no further maintenances <br /> required . If the drain valve fails testing , remove the <br /> valve , soak in water and use high -pressure air, if <br /> needed , to clean . Reinstall the drain valve to its <br /> proper position and test the valve with CARB <br /> procedure TP-201 . 1C or TP-201 . 1 D . If problems <br /> persist , replace the drain valve with P/N 1 DK-2100- <br /> EVR (specified torque 11 . 5 ft- lbs min to 13 . 5 ft-lbs <br /> max , 5/ 16- 18 UN thread ) .
