POSITION 1 - Position 1 is the <br />"tripped" or "reset" position. The <br />'96 LD -2000 goes into this posi- <br />tion when the pressure in the <br />delivery system falls to 4 psi or <br />less at the leak detector. <br />In the reset position, the '96 LD - <br />2000 is ready to look for a leak <br />in the delivery system the next <br />time the submersible pump is <br />turned on. With the pump <br />turned on, the '96 LD -2000 will <br />allow approximately 1.5 gallons <br />of product per minute to enter <br />the delivery system through a <br />cross hole in the poppet. <br />In Position 1, a portion of the <br />cross hole is positioned around <br />the narrow part of the metering <br />pin. Pressure will build very <br />quickly to 12-15 psi. As the <br />pressure builds in the delivery <br />system, it also increases under <br />the piston in the top of the '96 <br />LD -2000. This pressure causes <br />the piston and poppet to move <br />upward. <br />i <br />i <br />i <br />Full Pump <br />Prreswre <br />POSITION R - When pressure <br />in the delivery system has <br />reached 12-15 psi, the piston <br />and poppet assembly moves to <br />Position 2 - the "leak sensing" <br />position. <br />As the poppet moves to this <br />position, the cross hole in the <br />poppet centers around the head <br />in the metering pin. Since the <br />head of the pin is considerably <br />larger than the shaft, flow is <br />restricted from 1.5 GPM to 3 <br />GPH or less. <br />If there is a leak in the delivery <br />system of 3 GPH or more, the <br />pressure in the delivery system <br />will not rise, and the '96 LD - <br />2000 will stay in this position. If <br />there is no leak in the delivery <br />system, the pressure will con- <br />tinue to rise. <br />Pressure <br />POSITION 3 - If the <br />pressure continues <br />to rise, the '96 LD - <br />2000 will move to <br />Position 3 - the "full <br />flow" position. In <br />Position 3, the '96 <br />LD -2000 will allow <br />full flow of product <br />from the sub- <br />mersible pump to <br />enter the delivery <br />system. <br />For further information about the `96 LD -2000 or other leak detection equipment, <br />contact your local distributor or call. <br />APOR`Ess MANUFACTURINGjr INC♦ <br />9234-C East Valley Road - Prescott Valley, AZ 86314 <br />1-800-367-0185 - (520) 775-5191 - FAX (520) 775-5309 <br />Printed on Recycled Paper Made in the United States of America <br />ANY FUEL 1I <br />ANY LINE! <br />ANY PUMP*.1 <br />*see technical specifications <br />vvlw <br />, <br />➢ ; <br />t <br />PEI <br />'IW MUIPME14T W <br />aVml <br />Vaporless Manufacturing, Inc. <br />Leak Detection Equipment <br />for the Petroleum Industry <br />
