VM1 Vaporless Manufacturing, Inc. Quality Petroleum Equipment Solutions for Over 20 Years Leak Detectors iii; ll'r Before Installation: 1. If the line system is new, before installing a leak detector, purge the system of any air. 2. Turn off the submersible pump breaker and install the VMI LDT-890 Leak Detector Tester at the impact valve of the farthest dispenser. Following directions of the LDT- 890 Test Protocol. Determine (leed-back (air in line) - should be 400 ml or less, pump pressure (should be 14-5( psi), line pressure with pump off (establish pump pressure relief psi). 3. Before replacing an existing leak detector because of 1) Failure to open 2) Leak detector is slow to open, determination should be made as to; Is this line system tight? Is thermal contraction slowing down the opening time of the leak detector? A leak below 3 gph * 10 psi will slow down the opening time of a leak detector. Thermal contraction will also slow down opening time of a leak detector. Should a precision line test be conducted to ensure line integrity? A line test should also be conducted when installing a leak detector in the system for the first time. 1. Shut off the power to the submersible pump at the breaker box. 3. Shut ball valve at discharge of turbine. 4. Remove the existing leak detector or 2 -inch pipe plug in the submersible pump or adapter tee. 5. Apply a "UL Classified" (QLSR) pipe joint sealing compound (for use with petroleum products) to all threads before final assembly. (Before screwing the leak detector into the pump or the adapter tee. Tighten the leak detector down firmly to make sure tI ere is no leakage. (Caution - do not over -tighten the leak detector. Over-tighteniop could cause undue stress on the pump or the leak detector.)
