how to order replacement parts
1. Refer to the exploded view drawings on pages 24-27. Find the four-digit item number of the part that needs replaced. Item
numbers are listed on the exploded drawings.
2. In the red Owner’s Information Packet supplied with the meter, you will find a computer printout titled Parts List. The Parts
List lists each item number alongside a five-digit part number. The part number identifies the specific individual piece, kit, or
complete assembly used to assemble that particular meter.
3. Contact your distributor and give them the five-digit part number. Your
distributor will use it to find the correct component for your meter.
