Master Meter, Inc.  101 Regency Pkwy, Mansfield, TX 76063  T: 817-842-8000  F: 817-842-8100  MasterMeter.com
AT THE TIME OF INSTALLATION:
1. Thoroughly flush the service line upstream of the meter to remove dirt and debris.
2. Remove meter spud thread protectors. Note: To protect the meter spud threads, sore
the meter with the thread protectors in place.
3. Set the meter in the line. Arrows on the side of the meter and above the outlet spud
indicate the direction of flow.
4. Do not over-tighten connections; tighten only as required to seal. Do not use pipe
sealant or Teflon tape on meter threads.
5. With upstream shutoff valve only: Open the shutoff valve slowly, to remove air from
meter and service line. Open a consumer faucet slowly to allow entrapped air to escape.
Close the customer Faucet.
5.1. With upstream and downstream shutoff valves installed:
A. To test the installation for leaks: Close the outlet (downstream) shutoff valve.
Open the inlet (upstream) shutoff slowly until the meter is full of water.
B. Open the outlet (downstream) valve slowly until air is out of the meter and
service line. Open a customer faucet slowly to allow entrapped air to escape. Close
the customer faucet.
