2 Installation and Startup
2.1 Install the Power Pack
You must install the power pack for the EN1550 to function.
To install the battery pack:
1. Carefully align the three power pack pins to the three
holes in the top of the register and press down evenly,
keeping the pins perpendicular to the holes.
Caution: Install the power pack carefully. If the pins are
not kept perpendicular with the register during installation,
they may break. Never install the power pack at an angle.

2.2 Install the Meter
To install the meter:
1. Flush the service line to remove debris prior to installing
the meter.
2. Install suitable inlet and outlet meter valves and
couplings/setters if they are not already present.
• Inovonics Wireless recommends installing a shut-off
valve before the meter.
• Ensure appropriate space is allowed in the line for the
meter and two couple gaskets. The gap from gasket to
gasket should be 7 1/2 inches.
• Ensure the pipe ends are aligned so that the coupling
and meter threads engage without binding or cross-
threading.
• Make sure to adhere to local plumbing codes and
regulations.
3. Remove the meters thread protectors and spud caps.
• Ensure no debris enters the meter during installation.
4. Place the coupling gaskets inside the coupling nuts and
set the meter in the line.
• For best results, install the meter in the horizontal
position, with the register di l facing upward.
• The direction of the flow marked on the meter must
agree with the direction of water flow.
5. Start the coupling nuts by hand, then use a wrench to
tighten.
• Be careful not to cross-thread the connection.
6. Make sure to support the meter if plumbing it to PVC.
