Call factoryfor Return Merchandise Authorization (RMA) number and return instructions.THIS IS IMPORTANT INFORMATION.READ IT CAREFULLY BEFORE BEGINNING WORK.1) Inspect meter for damage that may have occurred during shipping.Report any damage to the container to the freight carrier immediately.2) Remove any shipping material placed in the inlet and outlet of themeter. (This is done to prevent damage caused by movement of thefloat during shipping).3) Make sure your pressure, temperature, fluid and other requirementsare compatible with the meter and components (including o-rings).4) Select a suitable location for installation to prevent excess stress onthe meter which may result from:a) Misaligned pipe.b) The weight of related plumbing.c) “Water Hammer” which is most likely to occur when flow issuddenly stopped as with quick closing solenoid operatedvalves. (If necessary, a surge chamber should be installed. Thiswill also be useful in pressure start-up situations.)d) Thermal expansion of liquid in a stagnated or valve isolatedsystem.e) Instantaneous pressurization which will stress the meter andcould result in tube failure.NOTE: In closed thermal transfer or cooling systems, install themeter in the cool side of the line to minimize meter expansion andcontraction and possible fluid leaks at the threaded connections.5) Handle the meter carefully during installation.a) Use an appropriate amount of teflon tape on external pipethreads before making connections. Do not use paste or sticktype thread sealing products.6) Install the meter vertically with the inlet port at the bottom.No piping runs are required. Because the guide rod extendsfrom the top of the meter during operation, 4” of straight pipemust be provided at the outlet of the meter.7) Meters with stainless steel fittings will support several feetof pipe as long as significant vibration or stress resulting frommisaligned pipe are not factors8) Meters used in gas service should have suitable valves plumbed inat the inlet and outlet of the meter. These valves should be no morethan 1-1/2 pipe diameters from the meter ports. The valve at theoutlet should be used to create back pressure as required to preventfloat bounce. It should be set initially and then left alone. The inletvalve should be used for throttling purposes. Depending on theinstallation, valves may not be essential, but they are most useful inmany installations. Remember: To get a correct reading of flow in gasservice, it is necessary to know the pressure right at the outlet of themeter (before the valve).ADDITIONALLY:• 7710 Series meters are designed for vertical installation only. (Inlet atbottom, Outlet at top)• Do not remove or adjust the screws on the back of the indicatorhousing. These screws were positioned during factory calibration andrepresent the zero adjustment.
