Safety and Preliminary Checks
Observe the following safety and preliminary checks before and during each instal-
lation:
• Verify that you are at the location specified on the Site Work Order.
• Verify that the site is safe for you and your equipment.
• Notify the customer of your presence and tell the customer that you will need
access to the water meter.
• If the Site Work Order does not have an MIU ID number on it, write in the ID
number(s) of the MIU you are about to install. If the Site Work Order already
has an MIU ID number on it, verify that it matches the ID numbers on the MIU
you are about to install.

• ARB III, IV, and V
• ProRead (ARB VI)
• ProRead AutoDetect
• E-Coder (ARB VII)
• Invensys ECRII, ECR III *
*when programmed in ECR II 6-wheel format
Before installing an MIU, the encoder register must be correctly wired and/or pro-
grammed to work with the MIU. ProRead (ARB VI) encoder registers do not
require programming.
