OPW Installation and Maintenance Instructions OPW 1DK-2100 EVR Replacement Drain Valve IMPORTANT: Please read these warnings and use the assembly instructions completely and carefully before starting. Failure to do so may cause product failure, or result in environmental contamination due to liquid leakage into the soil, creating hazardous spill conditions. IMPORTANT: Check to make sure the unit is intact and undamaged and all parts have been supplied. Never substitute parts for those supplied. Doing so may cause product failure and void warranty. WARNING -DANGER: Using electrically operated equipment near gasoline or gasoline vapors may result in a fire or explosion, causing personal injury and property damage. Be sure that the working area is free from such hazards, and always use proper precautions. NOTE: At all times when product is in the storage tank keep the riser pipe capped, so the vapors cannot escape into the environment. The OPW 1DK is an optional drain valve replacement kit for the OPW 1 Spill containers series. It is designed to return incidental spillage of liquid back to the underground storage tank. HOW TO INSTALL 1.Remove and discard existing drain valve and 0 - ring. 2.Clean any dirt or debris from the sealing surface where the new drain valve will be installed. 3.Apply any common grease or light oil to the new supplied O-ring. Assemble the O-ring into the spill container base. 4. Insert the 1DK into the spill container O-ring. Be sure that the drain valve seats flush with the floor of the spill container base. 5.The pull lever of the 1DK MUST be positioned halfway between the riser pipe nipple and the spill container bellows. Rotate the drain valve until that position is attained. 6. Secure the 1DK by installing the provided retaining clips and nuts. Tighten the nuts to a torque of 11.5 ft -lbs min. to 13.5 ft -lbs max. 7.The drain valve is now installed and ready for testing. HOW TO TEST Upon preliminary installation perform the California Test Procedures. Their Test Procedures will check the seals between the drain valve, nipple and rotatable adapter. To to st the spill containers base and bellows fill, the container with water. A drop in the water level of 1/16" or more after one hour means that a leak exists. To determine where the leak is, look for a steady stream of bubbles coming from one of the joints. NOTE: Do not drain the water into the UST after the test is complete. Water must be disposed of per local requirements for hazardous waste. If a leak is observed in the Test Procedure, check to see that the drain valve poppet is sealing properly. To do this, lift up the drain valve pull chain several times to actuate the poppet. This will ensure that the drain valve poppet is seating properly. If this doesn't correct the leak remove the 1 DK valve and inspect the O-ring for nicks or tears, replace if needed, also clean the sealing surfaces of the spill container base that the 1 DK valve and O-ring are installed into. Reinstall 1 DK valve and repeat test. If spill container passes the Test Procedure but does not hold water then there is a leak in the bucket and will need to be replaced. Operation and Maintenance: To open, pull drain valve chain up and hold open until liquid is drained. To close, release chain After each fuel delivery, the operator must remove any standing fuel from the container. Fuel can be removed by actuating the drain valve or with a gasoline absorbing disposable towel. Annually: Inspect and clean the interior of the spill container and drain valve screen. Remove accumulated dirt and grit. If the drain valve screen becomes clogged, remove the valve, soak in water and use high-pressure air to clean. Reinstall the drain valve to its proper position and test the valve per the appropriate California Test Procedure ortant:Leave these instructions with Station Flmp erator.
