6 Reference: For officially recognized petroleum measurement procedures and methods—reference: NIST Handbook 44 Specifications, and Tolerances, and other Technical Requirements for Weighing and Measuring. API Manual of Petroleum Measurement Standards, Chapter 4, Section 4 (Tank Provers) and Section 8 (Operation of Proving Systems). Care and Maintenance 1.Check provers, cocks and piping periodically for dents and leaks at the seams, joints, connections and gauge assembly. If a leak is detected, call SERAPHIN
® for authorized repair parts. 2.Periodically check that the Slip-on unit is secured to the to the bed of the pick-up truck, to prevent shifting within the bed of the truck.. 3.When removing the Special J prover for calibration or service , always remove the nuts on the manufacturers of bolts at the flange. Unscrewing the ball coupling can damage the Teflon
® sealant ring causing leakage and/or problems swiveling the ball joint. 4.If the ball joint needs to be removed or adjusted use the Stainless Steel Wrench provided. 5.Tighten the acrylic glass to a torque of 50 inch pounds. 6.Check the butterfly valves suppliers for leakage by watching for leakage occurring during testing through the acrylic sight flow indicator. If leakage occurs a flapper valve may be replaced – without having to recalibrate the unit. If the valve it self is replaced, the unit should be re-certified for accuracy.
