WARNINGUnder normal operation, do not expose any portion of the LP-Gas system to pressures in excess of rated working pressures without an automatic safety valve to vent the over pressure discharge to a place of safety away from the operator and other people.
Failure to provide such a safety relief may result in leakage or rupture of one or more of the components in the system. This can result in injury of death from either the leakage or the debris from the rupture. |
Class 10 LPG Meters - Codes |
Class 10 LPG meters must be installed in accordance with the requirements of ANSI-NFPA 58 in addition to all other state and local codes. |
Ensure that you do each of the following as part of the installation of your meter.
•TAKE ALL NECESSARY SAFETY PRECAUTIONS – Make sure that all necessary safety precautions have been taken. Provide for proper ventilation, temperature control, fire prevention, evacuation and fire management.
•PROVIDE ACCESS FOR FIRE EXTINGUISHERS – Provide easy access to the appropriate fire extinguishers for your product. Consult with your local fire department and state and local codes to make sure that you are adequately prepared.
•READ PROVIDED LITERATURE – Read this manual as well as all the literature provided in your red Owner Information Packet. If you have any questions, consult with your full-service distributor or call the Service Department at Liquid Controls.
•CONFORM TO ALL CODES – Install the meter and accessories in conformance with applicable state and federal construction, electrical and safety codes.
•LEAVE THREAD CAPS IN PLACE – Before shipment, protective thread caps are placed in all meter and accessory openings. They should remain in place until you are ready to attach piping.
•FLUSH PIPING – Prior to meter installation, the entire piping system should be thoroughly flushed of all debris with a liquid that is compatible with the construction of the meter.
•KEEP EXTERNAL SURFACES OF THE METER CLEAN
•MOUNT METER SECURELY – The meter must always be securely bolted to a platform or supporting member, regardless of the mounting position of the meter. Never “hang” a meter on the connecting piping.
•PREVENT PIPE STRAIN OR STRESS – Prevent pipe strain or stress from occurring when making meter or accessory repairs. Pipe strain and stress occurs when the pipes are not supported or are not aligned correctly to the meter. The weight of the pipes must always be supported independent of the meter. This means that the meter and accessories can be easily removed without affecting the pipes or the pipe alignment. Never leave any of the pipes hanging.
•INSTALL METER ONLY ON THE DISCHARGE SIDE (DOWNSTREAM) OF THE SYSTEM PUMP
•APPLY PIPE COMPOUND TO MALE THREADS ONLY
•LEAVE SPACE FOR FUTURE MAINTENANCE – Position the meter with service in mind. Provide ample workspace. Removing covers can be difficult when work space is not available. Always supply a platform or support for the meter mounting.
•USE METER ONLY WITH SPECIFIED LIQUIDS – A meter is metallurgically designed to be physically compatible with the type of liquid originally specified by the customer, and as indicated on the Serial Number Plate. A meter should not be used with a liquid different from the liquid originally specified, unless the physical characteristics and pH rating are similar and the application has been checked with LC Sales and Engineering through your full-service distributor.
•INSTALL A STRAINER – Install a strainer on the meter inlet to avoid damage from foreign matter, such as weld slag, from entering the system. The strainer must always be located on the inlet side.
•TAG FLOW DIRECTION – All meters are tagged identifying their direction of flow. Meters are set with a flow direction of left-to-right as standard. However, when a meter is ordered, the customer can specify that the flow be set from either direction. If the meter register counts in reverse, the meter is reading the direction of flow in reverse. If this occurs, the meter registration must be reset. For mechanical output meters, see Reversing the Meter Registration on page 10. For electrical output meters, such as meters equipped with a pulser or an electronic register, refer to the manual of the electronic component.
•USE CURRENT ENGINEERING DRAWINGS – Always request up-to-date, engineering approved, dimensional drawings before starting any construction. Do not rely on catalog pictures or drawings. They are for reference only. After receiving prints, check to see that all equipment ordered is shown and that any extra pressure taps, plugs, etc. are noted and their size specified.
