VST Installation Procedure for Phase II EVR Vacuum Assist Safety Breakaway Devices Part Number Series: VST-HEVR-SBK; VST-ISVR-SBK 4. Tighten breakaway connection to 50 ft.-lbs. of torque. DO NOT OVER 7. Measure the resistance between the dispenser outlet casting and the tip of TIGHTEN. Use the hex on the breakaway body to tighten. Use a torque the nozzle spout.Use an electronic multimeter set on the high range of the wrench with an open-end attachment to fit the hose couplings and an open- ohmmeter function.Resistance should not indicate more than 70,000 ohms end wrench to properly tighten breakaway connections. DO NOT USE per foot of hose.Example:The measured resistance for a 12-foot hose must channel-locks or pliers to tighten connections.Proper ft.-Ib.torque may not not exceed 840,000 ohms(840 kilohms). be achieved with these tools. BREAKAWAY REATTACHMENT PROCEDURES 5. Purge air from the system by pumping one-tenth(1/10)to two tenths(2/10) These VST reattachable breakaways can be reconnected in either one of two of a gallon of fuel into an approved container.Inspect each breakawayjoint methods: connection for liquid leaks and meter creep. Make proper adjustments at METHOD 1:Use of the VST Breakaway Assembly Tool(VST-BAT-200)with the the breakaway connection if necessary. appropriate reassembly plates for this breakaway. 6. Check the nozzle shut-off action by dispensing fuel into an approved 1. Follow INSTALLATION PREPARATION steps 1 -3. container at least three times to assure proper automatic operation. To test,operate the nozzle and submerge the spout tip in fuel until the fuel 2. Inspect both safety breakaway halves for damage that may have occurred level covers the vent hole.The main valve of the nozzle automatically shuts during separation. Include looking for external damage to the product, off when liquid covers the vent hole at the end of the spout.The dispenser damaged threads,damaged 0-rings,missing 0-rings,proper placement of should deliver a minimum of 3 gpm. Hold open latch will disengage 0-rings,etc.If damage is detected,replace with new product. automatically when liquid covers the vent hole in the spout. 3. Prior to reassembling,be sure the mating parts are undamaged and clean. Figure 2. 4. Lightly lubricate ALL 0-rings on mating connections with petroleum jelly or VST Breakaway Assembly Tool other suitable lubricant. 5. Utilize the VST Breakaway Assembly Tool with the appropriate reassembly plates to reassemble the breakaway.The tool is used to provide appropriate leverage for the ease of reassembly of the breakaway.This can be done without disassembling the hoses from the breakaway halves.See Figure 2. 6. Press the button on the VST Breakaway Assembly Tool to spread the end clamps apart. This will allow for the two separated breakaway halves to fit between the top and bottom clamps. 7. Slide the top clamp of the VST Breakaway Assembly Tool behind the hex on the breakaway half still connected to the whip hose.See Figure 2. 8. Slide the separated bottom half of the breakaway, with curb hose and nozzle attached, onto the bottom clamp of the VST Breakaway Assembly Tool.See Figure 2. w 9. Slowly squeeze the VST Breakaway Assembly Tool trigger to bring the breakaway halves together. 10.Carefully align the two breakaway halves. " a. Align the anti-rotation studs(2)inside the breakaway half on the curb 19$ hose with the slots(2)on the other half of the breakaway attached to the whip hose.See Figure 3. �r 11.Continue squeezing the VST Breakaway Assembly Tool trigger to finish reassembly. 12.The two aligned breakaway halves need to be assembled concentrically (properly aligned)until they snap into place. a. Listen for a "click"to indicate that the two halves have been properly t reattached. b. If the two breakaway halves become cocked(misaligned)or otherwise do not snap together easily,pull them apart and repeat steps 7-12. CAUTION:Reconnection can cause a small amount of gasoline to leak out of the breakaway. A towel wrapped loosely around the breakaway can help to minimize spills. 6-2 CARB Approved IOM 6—EVR Vacuum Assist Breakaways VR-201 and VR-202 09/16
