5. Pallet Push method for installing CheckMate ® Valve 11. Pallet Push for Larger CheckMate ® Valves Larger CheckMate ® valves can be pushed into the pipe utilizing the shipping pallet. The pallet should be placed perpendicular to the valve being inserted into the pipe. Then, with assistance from an excavator, push with consistent even force against the shipping pal - let to insert the CheckMate ® valve into the pipe. See the image to the right for the suggested positioning and usage of the excavator’s shovel assistance for larger-sized CheckMate ® valves. Clamps must be installed to prevent damage to cuff. 5 12. Corrugated Pipe and Smooth Wall (PVC, HDPE) Pipe Installation For installation on corrugated pipe, it is recommended that the cor - rugations be filled with hydraulic cement (or similar material) that will provide a smooth I.D. For smooth wall pipe, it is recommended that the valve be pinned.

CHECKMATE ® INLINE CHECK VALVES INSTALLATION, OPERATION AND MAINTENANCE MANUAL The revolutionary design of the CheckMate ® Inline Check Valve provides superior backflow prevention and odor mitigation in stormwater, CSO and SSO outfalls. The CheckMate's ® custom- engineered, all-rubber unibody design eliminates costly back - flow from oceans, rivers and interceptors. The valve's unique elastomer fabric and wire reinforced design provides a proven record of maintenance-free performance, cost savings and results that no other inline check valve can match. The Check - Mate ® is built to suit all your site-specific and flow needs. The CheckMate ® has a 100% fabric and elastomer construction that eliminates corrosion problems. Because the CheckMate ® is made with a unibody construction, there are no mechanical components that trap debris, corrode or fail. The CheckMate ® Valve's inherent flexibility virtually eliminates seating problems. The CheckMate ® remains in the closed posi - tion until forward differential pressure opens it. The fabric-rein - forced elastomer CheckMate ® Valve seals around silt and small debris, preventing unwanted backflow. The major advantage of the CheckMate ® Valve is its extremely low headloss. The CheckMate ® can open to a near full pipe diameter. This maximizes flow capacity of the outfall, which is particularly beneficial in low-lying areas where limited driving head is available. Tideflex ® Technologies recommends pinning all CheckMate ® Valves for added security and stability. CheckMate’s ® effectively have a zero face-to-face dimension because they fit completely inside of the pipe. No modification of piping is required provided adequate pipe length exists.

3. CheckMate ® Rubber Adhesive Strip Build Up Procedure 5. Rubber Adhesive Strip Build up When valve O.D. is smaller than the pipe I.D., one-sided rubber adhesive strip is used to build up the O.D. of both CheckMate ® cuffs to the actual pipe I.D. NOTICE: Clean and dry the exterior of the valve prior to beginning rubber adhesive strip build up procedure. STEP A: Place the valve on a solid, flat surface with the clamped end hanging slightly over the edge of the surface. STEP B: Slowly rotate the valve while firmly pressing the rubber adhesive strip onto itself in concentric layers until valve O.D. is equal to or a fraction smaller than pipe I.D. STEP C: Repeat steps A and B on the opposite side of the valve to ensure uniformity of the CheckMate’s ® O.D. is consistent and matches the pipe I.D. STEP E: Check O.D. of the valve to ensure it fits snugly into the I.D. of pipe. If loose, add another layer(s) of the rubber adhesive strip. STEP D: Lubricate the valve and rubber adhesive strip surface. Slide valve into pipe. Ensure the area marked TOP is in the 12:00 position. STEP F: Once in place, tighten the clamp to secure it against the pipe and compress the rubber ahesive strip. 3

Preparation The CheckMate ® Valve uses expanding clamp(s) to exert pressure outwards on the walls of the valve to wedge it in place within the pipe. The walls of the pipe should be clean and free of debris prior to installation. The valve should be inserted fully into the pipe so that no part of the cuff or bill extends outside the pipe. Ensure that the valve is not slanted at an angle with the bill pointing upwards or downwards. The valve centerline should be parallel to the pipe centerline. Tideflex ® Technologies recommends pinning the CheckMate ® Valve on all installations. See below. Four pre-drilled holes are provided in each expansion clamp. At least one clamp should be pinned. On exposed pipe, holes can be drilled through the valve and pipe, and a bolt run through secured with a nut. For buried pipe, silicon or similar sealant should be used to seal bolts. 7. Lubrication The outside of the valve can be lubricated with a water-based lubricant prior to inserting the valve into the pipe. If the taping procedure has been used, the surface of the tape can be lubricate to aid insertion. 8. Plumb Lines and Arrows The CheckMate ® Valve arrives with a “top” arrow, “flow” arrow and plumb lines, marked in white, at the 12:00 and 6:00 position of the valve. Utilize this marking to orient the valve in the pipe, as well as to ensure the valve is oriented correctly in pipe section. 9. Valve Orientation The CheckMate ® Valve must be installed in a horizontal pipe. Valves 4" – 18" (nominal) are supplied with a single clamp. The clamp turnbuckle should be oriented at top dead center as delinated by the plumb line. Valves 20” – 60” (nominal) are supplied with two clamps. The turnbuckles should be oriented 45° from the top center plumb line. The 72” is supplied with three clamps. The turnbuckle for one clamp to be at top center. The other clamps to be 45° to each side of top center. C heckMate ® Installation Procedure CAUTION: If you expand the clamp excessively at this step it will hinder or prevent the CheckMate ® valve being fully inserted into the pipe. CheckMate ® Clamping Diagrams CAUTION: Do not use petroleum-based lubricants on this product or on the vulcanized rubber tape. 4 Flow 10. Insertion Into Pipe Clamp to support the shape of the cuff should be hand tight and should be extended outward, but only tight enough to loosely keep the shape of the cuff during installation.
2. 1. Product Shipping Valve sizes 2" - 18" are furnished with one clamp. Valves 20" - 60" ship with two clamps. 72" valves ship with three clamps. NOTE: A clamp is installed on each end of the valve to keep the valve’s shape during transit and storage. Once the installation orientation is determined the CheckMate ® valve will be clamped from either the upstream or downstream side. For valves with two or three clamps, they can be installed onto the same side of the valve and offset from each other, as illustrated in Figure 1. 2. Unpacking & Lifting Do not use sharp tools when unpacking this product as it may damage the valve. For larger CheckMate ® valves, the valve should be lifted with either a sling or with supports around the O.D. at each side of the valve to ease the installation procedure. Do not place an object through the valve in order to lift. 3. Inspection of Pipe I.D. Check the inside diameter (I.D.) of the pipe section for rough or damaged areas. The inside surface should be uniform and relatively smooth. Long gouges or cracks in the pipe may allow water to pass and should be filled prior to installation. Do not attempt to install a CheckMate ® in a smaller pipe I.D. 4. Pipe I.D. Measurements The pipe I.D. is to be checked in the field. It should be a consistent diameter for the length of valve and should not be out of round. When there is a +/- tolerance on the pipe I.D., the CheckMate ® Valve should be ordered to the smallest pipe I.D.. Then, rubber adhesive strip can be applied to both CheckMate ® cuffs to build the cuff O.D. up to the actual pipe I.D. See procudure in #5. NEVER... Install the valve at an angle NEVER... Install the Valve Backwards NEVER... Use Sharp Tools on Rubber NEVER...

7. The clamps should be checked for proper tension, and be sure that the inside of the valve is free of debris. Soft marine growth is normal on valves in submerged applications. Because hard marine growth such as barnacles will not bond well to the CheckMate ®, they can be easily removed. Also insert pins to ensure they are tight. STORAGE If your CheckMate ®, is to be stored for a period of time prior to installa - tion, the following storage guidelines will help to preserve the valve and assure a trouble-free installation: 1. Store in a clean, cool, dry location. Avoid exposure to light, electric motors, dirt, or chemicals. 2. Store valve vertically on floor or pallet. 3. Store valve to prevent other items from contacting check sleeve to prevent possible damage. 4. Store this manual with the valve, so that it is readily available at time of installation. TROUBLESHOOTING GUIDE Sleeve Inverted or Distorted 1. Excessive back pressure, water surge, or water hammer. Leaking Around Perimeter of Valve 1. Tighten clamp. 2. Check for cracks and holes in surface of pipe. 3. If taped, chec k tape to ensure the pipe I.D. has been fully sealed Backflow 1. Debris lodged inside bill.

It is important that the CheckMate ® is installed level within the pipe. The CheckMate ® may "gap open" if installed improperly. 2. The sealing area of the CheckMate ® must have room to expand outwards, while bottom of the sealing area rises. The area around the sealing area must be kept free of debris to allow the bill to close in order for the valve to seal properly. 3. The CheckMate ® effectively reduces the inside diameter of the pipe in which it is installed, creating a restriction. It may also create a "ledge" inside the pipe, causing standing water. 4. Back pressure in excess of the back pressure rating may cause valve failure. 5. Should the conditions that the CheckMate ® was designed for change, (line pressure, back pressure, chemical compatibility) the performance of the valve may suffer. 6. CheckMate ® Valves must be installed in true round pipe which is concentric across the entire length. Out of round pipe may cause the sealing area of the valve to distort and gap, which will cause the valve to leak. MAINTENANCE Inspection Valves should occasionally be inspected for damage, wear, and buildup of debris. The frequency of the inspections should be deter - mined by the severity of the service and the environment in which it operates. C heckMate ® Installation Notes 6
6. 13. Flanged Valve Bolt Torques The valve end with the rubber flange shall be installed using the backup rings provided. The sleeve split should be installed facing downstream, with the split in the vertical position. The installation bolt torque on the end flange bolts are listed in the table below. RECOMMENDED MINIMUM BOLT TORQUE Valve Size Bolt Size Torque (ft*lb.) 1” 1/2” - 13NC 20 1-1/2” 1/2” - 13NC 20 2” 5/8” - 11NC 30 2-1/2” 5/8” - 11NC 40 3” 5/8” - 11NC 40 4” 5/8” - 11NC 30 5” 3/4” - 10NC 40 6” 3/4” - 10NC 30 8” 3/4” - 10NC 40 10” 7/8” - 9NC 40 12” 7/8” - 9NC 50 14” 1” - 8NC 50 16” 1” - 8NC 50 18” 1-1/8” - 7NC 30 20” 1-1/8” - 7NC 30 24” 1-1/4” - 7NC 40 30” 1-1/4” – 7NC 30 36” 1-1/2” – 6NC 40 42” 1-1/2” – 6NC 50 48” 1-1/2” – 6NC 55 54” 1-3/4”– 5NC 60 60” 1-3/4”– 5NC 80 72” 1-3/4”– 5NC 100 Torque values are suggested minimum values. Torque all flange bolts in a star pattern, first to 50% of tabulated values, then retorque to 100% of tabulated values. If greater torque is required, continue retorquing in increments of 50% of tabulated values. Use of a high quality anti–seize compound on all bolt threads is recommended. Variables such as the surface finish on bolt threads, type of anti– seize compound used, and surface finish of the mating flanges all have an effect on the minimum torque required to obtain a leak– tight flange seal. During installation you may need to retorque the flange bolts several times for a proper seal. This will overcome any leaks due to the cold flow of the rubber sleeve flange. Always use a “star” pattern when bolting a check valve. 1 2 3 4 5 6 78 6
