Description of Operation <br /> The Healy Systems VP1000 Vacuum Pump is typically mounted in the lower hydraulic area of a dispenser or self- <br /> contained gasoline pump. It works as a component of a complete Stage II system which also includes a single <br /> universal control module and Healy Systems hanging hardware. It is intended for use by either OEM dispenser/pump <br /> manufactures or as an aftermarket retrofit to make existing equipment compatible with Healy Systems technology. <br /> Specifications:1/8 Hp, 120 VAC input,2 Amp AC <br /> Important: All electrical and hydraulic plumbing fittings referred to in these instructions must be UL "listed" or <br /> "recognized" for the purpose. <br /> Important: The VP1000 will increase the current draw of the dispenser by two amps. Use the label supplied to <br /> note this change. <br /> The preferred mounting position of the VP1000 Vacuum Pump is with the vacuum pump inlet and electrical connections <br /> facing upwards, towards the top of the dispenser(see Figure 1 below). If other mounting positions are desired because of <br /> mechanical constraints within the dispenser, please contact FFS Technical Services at 1-800-984-6266. <br /> Nozzle & Hanging Hardware MC100 Control Module VP1000 & Bracket <br /> LXXXXXj <br /> IIAIAIA LlINIPLIT-_ �-I.N'11L'2 IN"'�]T <br /> i <br /> - OUTPUT 2FAULT COMMONi <br /> FAULT INPUT <br /> i <br /> i IN <br /> TEACH <br /> JUMPERi <br /> OUTPUT <br /> POO <br /> � J <br /> Q <br /> ur <br /> _ i <br /> i <br /> Figure 1 <br /> Vacuum Pump Features <br /> • Operates at two speeds: Low Speed in response to one fueling point being activated, or High Speed if both fueling <br /> points are activated simultaneously. <br /> • Contains performance protection devices that will shut off the vacuum pump and disable dispensing if the vacuum <br /> pump is not operating properly. <br /> • Operates only with input signals from the control module, cannot be operated `stand alone'. <br /> • Contains low temperature activation circuits that turn the vacuum pump on at slow speed when the temperature drops <br /> below 40°F to prevent freezing. <br /> 8-4 <br /> GARB Approved IBM 8-Healy Universal Manual-Executive Orders VR-281 and VR-282 <br />
