For all types of STD Series meters:
1. Flush the line thoroughly after plumbing changes to eliminate the possibility of foreign materials reaching the meter and valve.
2. Do not exceed an operating pressure of 150 psi.
3. Install meter horizontally with the register facing up and the inlet port facing the supply water line.
4. It is recommended that if there is any possibility that the water supply contains foreign materials, a Carlon strainer be installed between the supply and the meter.
5. It is not recommended that the meter be run for long periods of time at the maximum rating as excess wear will result and the life of the meter will be greatly reduced.
6. To reduce potential harmful effects to equipment from water hammer, it is suggested that you install a Carlon slow-closing solenoid valve. Install valve between supply water line and meter.
7. Protect meter from freeze and heat in excess of 105 degrees F
8. For outdoor installation, protect meter from direct exposure to the elements.
9. Protect meter from any backflow of water opposite of indicated flow direction.
