New Meter Installation
1 The service line must be flushed prior to meter installation in
order to remove debris in the line.
2 Place an electrical grounding strap on the service line connecting
the inlet and outlet service lines on either side of the
meter setting.
3 Before installing the R900i SP meter, remove the thread
protectors and spud caps. Be sure that no debris enters the
meter during installation.
Some items may not apply to your specific installation or the list may not contain all required tools
or materials.
Always follow your company's safety practices and installation guidelines when
installing an R900i SP. Never perform an installation during a lightning storm or
under excessively wet conditions.
Suitable inlet and outlet meter valves and couplings/setters must be installed
if they are not already present. Appropriate space must be allowed
in the line for the R900i SP meter laying length and two couple gaskets.
The pipe ends must be sufficiently aligned so that the coupling and ECoder)
R900i meter threads can engage without binding or cross-threading.

4 Place the coupling gaskets inside the coupling nuts and set
the R900i SP meter in the line. The R900i SP
meter should be in the horizontal position with the register
dial facing upward. The direction of flow marked on the meter
must agree with the direction of water flow.
5 Start the coupling nuts by hand then use a wrench and tighten
sufficiently to prevent leakage. Be careful not to cross-thread
the connections.
6 Slowly open the R900i SP meter outlet valve slowly.
Open a down stream faucet and run enough water to dissipate
entrained air and flush the line. While the faucet is open,
check to see if the R900i SP meter is operating correctly.
7 Turn off the faucet and check the R900i SP meter installation
for leaks.
8 To activate the LCD and begin the MIU transmissions, use a
small flashlight to activate the light sensor. The light sensor is
recessed under a small hole near the center of the faceplate.
9 Test the installation as described in “Testing the ECoder)
R900i Inside Installation” on page 13.
