Water Module Installation Instructions
General
This leaflet contains instructions for Elster's water meter module (see Figure 1) for use on
water meters to provide readings to the EnergyAxis System. For proper installation and
maximum life of the modules, use the following procedures. All modules are programmed
and sealed at the factory before shipment.
Familiarize yourself with the location and identification of the terminals on the water meter
register before any installation procedure.

Installation
Direct (Integral) Mounting
The water module is shipped pre-wired and attached to a new water meter. Install the water
meter with the EnergyAxis water module as you would any other water meter.
Pit Applications
The water module is shipped pre-wired to the new water meter. However, it is necessary to
mount the water module to the pit cover. The water module is designed to fit standard
(1-
7
/
8
inch diameter) holes in pit covers.
1. Unscrew the cap from the water module. The dome-like cap is fitted to a threaded
cylinder on the top of the module.
2. Adjust the spacer nut as necessary to account for the thickness of the pit cover,
leaving the threaded cylinder protruding above the cover to screw the cap on.
3. Insert the water module's threaded cylinder through the pit cover hole from the
inside of the cover.
