KS Updated 05/27/03 <br /> 3. The actual injection locations should be marked prior to the start of installation <br /> activities to facilitate the application process. <br /> 4. To expedite the installation process, Regenesis strongly recommends heating the <br /> HRC-X''M material in a hot water bath prior to application. Once the HRC-XTM <br /> reaches a temperature of approximately 110 °F (43 °C) it becomes less viscous <br /> and can be pumped much more easily. This is accomplished by adding hot water, <br /> 160 °F+ (71 °C), to a large trough (plastic or metal) and then placing the buckets <br /> of HRC-XTM product inside. Regenesis has used the following methods to heat <br /> up water: <br /> o Heated pressure washer <br /> o Stream cleaner <br /> o Camping stoves <br /> o Propane tanks <br /> "Please note that the buckets used to package the HRC-XTM product should not <br /> be heated directly, another medium such as water must be used so that the <br /> physical structure of the buckets is not jeopardized. <br /> 5. The period of time needed to heat the HRC-XTM product up to the desired <br /> temperature of 110 °F (43 °C) is highly dependent on ambient conditions (i.e. <br /> cold weather conditions will require more time) and can take up to 1.5 hours. <br /> 6. After the HRC-XTM product reaches the target temperature the installation <br /> activities can begin <br /> 7. Using an appropriate pump to install the HRC-XTM product is very critical to the <br /> success of the application as well as the overall success of the project. Based on <br /> our experience in the field, Regenesis strongly recommends using a pump that has <br /> a pressure; rating of at least 1,500 pounds per square inch (psi) and a delivery rate <br /> of three gallons per minute. <br /> 8. After the HRC-XTM product has been heated the direct-push unit can be moved <br /> over one of the targeted injection points and prepared for installation. The drive <br /> rod assembly should be fitted with a disposable tip on the first drive rod and <br /> pushed down to the desired depth. This process should be done in accordance <br /> with the manufacturer's standard operating procedure (SOP). Due to the viscous <br /> nature of the product, Regenesis recommends using drive rods with an inner- <br /> diameter of at least 0.625-inches. <br /> 9. The quantity of HRC-XTM product needed for each injection point should be <br /> poured into the pump's hopper after it has been heated to the appropriate <br /> temperature and before the drive rods are pushed down to the desired depth. <br /> 10. A sub-assemb]'.y connecting the delivery hose to the drive rods and pump should <br /> be used. The sub-assembly should be constructed in a manner that allows for the <br /> drive rods to be withdrawn while the material is being pumped. <br /> J:ATechnical Services\Installation Instructions\HRC\HRCA <br />
