8. After the new system is installed, shut the outlet shut-off valve.
9. Open the inlet shut-off valve slowly until the system is full of water and ensure that there are
no leaks.
10. Open the outlet valve slowly until air is out of the meter and service line.
11. Open a valve downstream of the system to ensure that no foreign debris in the water obstructs
the operations of the system.

2. Inspect the system for any parts that may have been damaged during shipping.
3. Turn off the water supply valves.
4. Pull the current meter out of the pit or disassemble current meter.
5. Orientate the new system so that the direction of the flow arrow on the system body is aligned
with the direction of the flow arrow in the plumbing system.
6. Install new system connection gaskets in both meter couplings.
Never use thin meter gaskets.
Do not over-tighten. You may tighten after turning on the water if leaks are present.
