CheckMate° Installation Notes <br />1. it is important that the CheckMate• is installed level within the <br />pipe. The CheckMate® may "gap open" t installed improperly. <br />2. The sealing area of the CheckMate• must have mom to expand <br />outwards, while bottom of the sealing area rises. The area amund the <br />sealing area must be kept free of debris to allow the bill to close in <br />order for the valve to seal property. <br />3. The CheckMate° effectively reduces the inside diameter of the <br />pipe in which it is installed, creating a restriction. It may also create a <br />"ledge" inside the pipe, causing standing water. <br />4. Back pressure in excess of the back pressure rating may cause <br />valve failure. <br />5. Should the condtions that the CheckMate• was designed for <br />change, (line pressure, back pressure, chemical comidedilily) the <br />performance of the valve may suffer. <br />S. CheckMate° Valves must be installed in true round pipe which is <br />concentric across the entire length. Out of round pipe may cause the <br />sealing area of the valve to distort and gap, which will cause the valve <br />to leak. <br />MAINTENANCE <br />Inspection <br />Valves should ocrasionally be inspected for damage, wear, and <br />buildup of debris. The frequency of the inspections should be deter- <br />mined by the severity of the service and the envimnmeM in which it <br />operates. <br />TIDEFLEX® TECHNOLOGIES WARRANTY <br />WNAWIIE$-nEMECIES O1C1JgMENS IIMPRTONOFLVBILItt <br />LY1ea oMemiz egreNbin w,lbng signed <br />600 North Bell Avenue <br />Carnegie, PA 16106 <br />Phone: 4122] 0044 <br />Fax 412 VO-7878 <br />Web : www.tldenemearn <br />The clamps should be checked for proper tension, and be sure that the <br />inside of the valve is free of debris. Soft marine growth is normal on <br />valves in submerged applications. Because hard marine growth such <br />as barnacles will not bond well to the CheckMate• they can be easily <br />removed. Also insert pins to ensure they are tight. <br />STORAGE <br />If your CheckMate•-is to be stored for a period of time prior to installa- <br />tion, the following storage guidelines will help W preserve the valve and <br />assure a trouble -free installation: <br />1. Store in a clean, cool, dry location. Avoid exposure to light, electric <br />motors, dirt, or chemicals. <br />2. Store valve vertically on floor or pallet <br />3. Store valve to prevent other items from contacting check sleeve to <br />prevent possible damage <br />4. Store this manual wit the valve, an that it is readily available at <br />time of installation. <br />TROUBLESHOOTING GUIDE <br />Sleeve Inverted or Distorted <br />1. Excessive back pressure, water surge, or water <br />hammer. <br />Leaking Around Perimeter of Valve <br />1. Tighten clamp. <br />2. Check for cracks and holes in surface of pipe. <br />3.
