PRIOR TO METER DISASSEMBLYFailure to follow this pre-disassembly procedure could result in property damage, personal injury, or death. Before disassembly of any meter or accessory component: •All internal pressures must be relieved and all liquid drained from the system in accordance with all applicable procedures. •Pressure must be 0 (zero) psi. •Close all liquid and vapor lines between the meter and liquid source.
For applicable safety rules, refer to local authorities and relevant NFPA Codes. |
DISCLAIMER |
Liquid Controls disclaims all liability for damage to meter or accessories because of corrosion, salting out of product, or separation of chemicals whether occurring during periods of use or storage. |
Ensure that you are mindful of the following when performing maintenance on the meter:
•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.
•SEASONAL METER STORAGE – If the meter is used for seasonal work, the meter should be removed from the system and thoroughly flushed with a compatible liquid at the end of each season. To flush the meter, remove the drain plug on the front and rear covers. Then flush the product from the front and rear covers. If flushing with water, extra care should be taken to drain the meter completely and dry all internal parts. Refill the meter immediately with a compatible liquid (or oil misting). Refilling is essential to preventing corrosion and ice damage that can result from any moisture that was overlooked after flushing and drying.
•DO NOT MAR OR SCRATCH – Do not mar or scratch any of the precision machined surfaces by prying or sanding parts.
•TORQUE ALL FASTENERS – Torque all fasteners such as screws and bolts in accordance with specifications listed in the Torque Chart in Reassembling the Meter.
•STONE THE MACHINED SURFACES – Stone the machined surfaces when reassembling the meter to
•assure that the machined surfaces are free of burrs and mars.
•REPAIR PULLED THREADS – Repair pulled threads with threaded insert fasteners. These can be used in many instances. Contact your full-service distributor for advice if this occurs.
•COAT THREADS WITH ANTI-SEIZE – Coat threads with anti-seize when removing and replacing bolts and castings in the meter.
•REMOVING FLANGE GASKETS – Remove flange gaskets when removing the flange assembly, always carefully scrape off the flange gaskets. Make sure that the flange surface has been scraped clean. Discard the old flange gasket and install a new flange gasket. Never reuse old flange gaskets.
