5. INSTALLATION OF PROCESSOR <br /> 5.1 PRE-INSTALLATION SITE REQUIREMENTS <br /> Selection of processor location should be based on the following <br /> requirements and considerations: <br /> 5.1 .1 Non-Hazardous area. <br /> 5.1 .2 A minimum horizontal distance of 20 ft. from any fuel transfer point (i.e. <br /> nozzles or storage tank drop tubes). <br /> 5.1.3 A minimum horizontal distance of 20 ft. from pressure/vacuum valve. <br /> 5.1.4 Processor must be located so there is a 2 ft. clearance on all sides for <br /> maintenance. <br /> 5.1.5 Remote from wheel traffic, foot traffic, and valuable ground level space. <br /> 5.1.6 Ease of pipe run to processor from underground storage tanks(s). <br /> Typically the processor connects to the storage tank vent pipes. However, <br /> the processor can be connected to any tank fitting except for the <br /> dispenser's vapor return pipe. Note, the vapor piping must slope 1/8" per <br /> foot to prevent condensate from blocking vapor path. A slope of 1/4" per <br /> foot is recommended. (See section 7.2.2 and FIGURE 8) <br /> 5.1.7 Ease of conduit run to Indicator Panel. <br /> 5.1.8 Do not locate processor on property easement. Consult local authority, <br /> such as City Hall, to determine width of set back from properly line. <br /> The preferred location for the processor is on the roof of the building to which the <br /> vent pipes attach. Many other locations are also practical such as ground mount, <br /> canopy mount, roof mount on a remote building, and satellite mount as noted in <br /> Figures 1 through 4. <br /> Page 14-5 <br /> ARB Approved IOM-14—Hirt VCS 100 Processor Installation Manual—Executive Order VR-205-B <br />
