5. Run the submersible with dispenser nozzles and valve"A"closed,but leave valve"B"open.When the vacuum reading reaches 20-28"Hg,shut the submersible off.The vacuum should hold for at least 15 minutes. If this worked,continue with the next step. If the vacuum does not hold,the Syphon Check Valve is not holding or the Test Fixture fittings may be loose. Providing the Test Fixture fittings are tight, remove the Syphon Check Valve and clean or replace it. Repeat this step until the problem has been corrected,then continue with the next step. Note: Syphon Check Valves may hold at high vacuum, but may fail under low vacuum. Test the Syphon Check Valve at a lowervacuum by bleeding off the vacuum and re-testing at 5"H g. 6. Run the STP with valves "A" and "B" both open and the dispenser nozzles closed. Normal priming should take approximately 5-10 minutes.When first priming with both valves open, the vacuum gage will indicate 0" Hg.After awhile,vacuum will begin to show. For every inch of mercury vacuum shown,the product level in the syphon pipes is about 1-1/7 feet above the tank fluid level.When air is being removed from the syphon system,the vacuum gauge needle will bounce. This bouncing should stabilize as more air is removed. If not, this would be a good indication thatthere is a leak in the syphon system. This air may also be visible if using a Test Fixture with cleartubing.The air would indicate that there is a leak in the syphon line between the tanks or the possibility of foreign material blocking the syphon pipe. Repair any leaks or blockage and repeat this step.If there is no evidence of air,then continue with the next step. 7. Close valve"B"and then shut off the STP.The gauge should hold constantfor 30-40 minutes after the submersible is turned off.The vacuum may increase if the syphon system wasn'tfully primed before closing the valve. If the vacuum drops, there is a leak in the syphon line between the tanks or the possibility of foreign material blocking the syphon pipe. Repair any leaks or blockages and then repeatthis step. Note: If there is a leak in the syphon line, product will drain out of the horizontal pipes before vacuum gauge readings indicate a leak. �a FAonfoid ��xhorge Neod k arm R4PLIO 011F Edrariable 0—Plugs nc� mm I+Ir�rI u tr �—J p'q W11ra Vapor Rei urn Tube L 1 El Flu mp Maty Pseemhly{PW Manifwd Q15chafge Head 3/8n Plug (e,movt- to access STh" Jct) Figure 2 Figure 3 (STP Extractable) (Top View of STP) Contact FFS Technical Support for any assistance Franklin Fueling Systems • 3760 Marsh Rd. • Madison,WI 53718 USA Tel: +1 608 838 8786 • 800 225 9787 • Fax: +1 608 838 6433 •www.franklinfueling.com 9-20 GARB Approved IBM 9-Liquid Condensate Trap-Executive OfdBps VR-201 and VR-202
