If the line system is new, before installing a leak detector, purge the system of any air. <br /> 2. Turn off the submersible pump breaker and install the VMI LDT-890 Leak Detector <br /> Tester at the impact valve of the farthest dispenser. Following directions of the LDT- <br /> 890 Test Protocol: determine bleed-back (line resiliency) - should be 400 ml or less, <br /> full pump pressure (should be 14-50 psi), and line pressure with pump off (static <br /> pressure). <br /> 3. Before replacing an existing leak detector because of 1) Failure to open, or 2) Leak <br /> detector is slow to open, determination should be made as to: Is this line system tight" <br /> Is thermal contraction occurring? A leak below 3 gph @ 10 psi will slow down the <br /> opening time of a leak detector. Thermal contraction will also slow down opening time <br /> of a leak detector. Should a precision line test be conducted to ensure line integrity? <br /> A line test should also be conducted when installing a leak detector in the system for <br /> 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 valve 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 undue stress on the pump or the leak detector.) <br /> Vaporiess Manufacturing,Inc <br /> 8700 East Long Mesa Drive,Prescott Vallev,Arizona 86314 <br /> 800-367-0185 928-775-5191 Fax: 928-775-5309 <br /> Emaii: vmi@vaporless.com Website: www.vauorie s.com <br />
