Notify the customer of your presence, and tell the customer that you need access to the water meter. Write the ID numbers of the CMIU you are installing, if the site work order does not include the numbers. Verify that the ID numbers match the ID numbers on the CMIU you are installing, if the site work order already includes them. -
Page 21: Installing A Register (Non Pre-Wired Or Potted Only)
When using a ProRead encoder register, the non-AutoDetect ProRead register must be programmed for three-wire mode. If connecting the CMIU 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 field programmer, and the format is set to (NTG) RF MIU Transport Driver Interface format (TDI). -

Do not exceed maximum cable lengths as defined in "Encoder Register Interface" on page 3. If the encoder register is prewired and potted, use Schotchloks for connecting the register to the CMIU. -
Page 25: Chapter 4: Wall Installation
Handle the CMIU carefully; however, no additional special handling is required. After unpacking the CMIU, inspect it for damage. If the CMIU appears to be damaged or proves to be defective upon installation, notify your Neptune sales representative. If one or more items requires reshipment, use the original cardboard box and packing material. -

Avoid installing the CMIU behind metal fences or walls. Make sure the pit location gives adequate room for installing both the CMIU and the pit antenna. Install the pit antenna above the lid in low traffic areas, as illustrated below, for maximum performance. -
Page 37: Pit Cmiu™ Installation
Recessing the installation reduces the range of the antenna. Figure 27 – Antenna Placement for High Traffic Areas Although the CMIU has a cable already attached (2 feet or 6 feet), some installations can require additional cable. In these cases, the maximum cable length between the encoder register and the CMIU depends on the register's manufacturer and model. -
