If the lime system is new, before installing a leak detector, purge the system of anv air <br />2. Turn off the submersible pump breaker and install the VMI LDT-890 beak Detector <br />Tester at the impact valve of the farthest dispenser. Following directions of the LDT- <br />890 Test Protocol. Determine bleed -back (air in line) - should be 400 ml or less, paimp <br />pressure (should be 24-50 psi), line pressure with pump Off (establish pump pressure <br />relief psi). <br />3. Before replacing an existing leak detector because of 1) Failure to open 2) Leak <br />detector is slotif to open, determination should be made as to; Is this line system tight'.' <br />Is thermal contraction slowing down the opening time of the leak detector? A leak <br />below 3 gph cQ 18 psi will slow down the opening time of a leak detector. Thermal <br />contraction will also slow down opening time of a leak detector. Should a precision <br />line test be conducted to ensure line integrity? A line test should also be conducted <br />where installing a leak detector in the system for the first time. <br />To Install the Leak Detector: <br />1. Shut off the power to the submersible pump at the breaker box. <br />2. Open nozzle at dispenser to relieve line pressure. <br />3. Shut ball vahre at discharge of turbine. <br />4. Remove the existing leak detector or 2 -inch pipe plug in the submersible pump or <br />adapter tee. <br />5. Apply a "UL Classified" (QLSR) pipe joint sealing compound (for use with petroleum <br />products) to all threads before final assembly. (Before screwing the leak detector into <br />the pump or the adapter tee. Tighten the leak detector down firmly to make sure <br />there is no leakage. (Caution - do not over -tighten the leak detector. Over -tightening <br />could cause undine stress on the pump or the leak detector.) <br />Vaporless N-tanufacturing, Inc, <br />8700 bast Lona iklesa Drive.
