VAPORLESS MANUFACTURING, INC. 8700 E. Long Mesa Drive Prescott Valley, AZ 86314 928 775-5191 * 800 367-0185 * FAX 928 775-5309 Installation of the 99/LD2000 and LD2200 Leak Detectors (Revised 3/15/01) Before Installation: 1. Before installing the leak detector, purge the system of any air. 2. Turn off the submersible pump and install the VMI LDT-890 Leak Detector Tester at the impact valve of the farthest dispenser. Turn pump back on. Following directions of the LDT-890 Test Protocol, determine bleed -back (for 99ILD2000 it should be 400 ml or less; for LD2200 it should be 250 ml or less), pump pressure (should be 28-32 psi), line pressure with pump off (establish pressure relief p.s.i.) 3. Run a precision line test. Before replacing an existing leak detector, a precision line test should 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. Not only will the line test tell you if the line is leaking, but it will also tell you how much line resiliency is present. It will also help do system diagnostics. To Install the Leak Detector: 1. Shut off the power to the submersible pump at the breaker box. 2. Remove the existing leak detector or 2 -inch pipe plug in the submersible pump or adapter tee. 3. Apply proper pipe dope to the threads of the leak detector. (Before screwing the leak detector into the pump or the adapter tee, be sure to check for and remove any casting remnants in the leak detector port.) Tighten the leak detector down firmly to make sure there is no leakage. (Caution - do not over -tighten the leak detector. Over -tightening could cause undo stress on the pump or the leak detector.) 4. Remove the dust cover from the '/2 -inch port on the top of the leak detector. Apply pipe sealant to the threads of the 90 degree compression fitting and install into the top of the leak detector. Tighten firmly, but do not over -tighten. 5. Remove the 1/4 -inch pipe plug from the tank test port on the submersible pump. Install the straight compression fitting into this port.
