Tools and Materials Table 5 below and Table 6 on the next page show the recommended tools and materials you need to successfully install the L900 MIU. It is possible that some items do not apply to your specific installation, or the list does not contain all required tools or materials. -
Page 21: Safety And Preliminary Checks
Notify the customer of your presence and tell them you need access to the water meter. Write in the ID number(s) of the L900 MIU you are about to install, if the site work order does not have an L900 MIU ID number. -
Page 22: Installation Of A Register (Non Pre-Wired Or Potted Only)
AutoDetect ProRead register must be programmed for three- wire mode. If connecting the L900 MIU to a new ProRead encoder register, or if a three-conductor cable is already connected to a ProRead encoder register, ensure that the ProRead register is programmed for three-wire mode using the ProRead programmer and its RF/L900 MIU 6, 8, or 10 ID TDI format. -
