This warranty is non-transferrable and is limited to replacement or repair. Theliability of King Instrument Company arising out of its supply of the products, or their use, shall not inany case exceed the cost of correcting defects in the products as set forth above.THIS WARRANTY IS A LIMITED WARRANTY AND SHALL BE IN LIEU OF ANY OTHER WARRANTIES,EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OR MERCHANT-ABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

Callfactory for 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.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 the meterin the cool side of the line to minimize meter expansion and contrac-tion 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.7) Meters with stainless steel fittings will support several feet of pipeas long as significant vibration or stress resulting from misaligned pipeare not factors.8) 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 the out-let should be used to create back pressure as required to prevent floatbounce. It should be set initially and then left alone. The inlet valveshould be used for throttling purposes. Depending on the installation,valves may not be essential, but they are most useful in many instal-lations. Remember: To get a correct reading of flow in gas service, it isnecessary to know the pressure right at the outlet of the meter (beforethe valve).
