11 Copyright: Chart Industries, Inc., Jan. 2003 <br />V Operation and Troubleshooting <br />CO2 Storage Vessel <br />INDICATION POSSIBLE CAUSE CORRECTIVE ACTION <br />Constant high vessel <br />pressure. <br />[(41) above 200 psi] <br />Normal condition for a few days <br />following a CO2 delivery. None <br />Normal when little or no CO2 is used. None <br />Economizer regulator (39) set too high. Call CO2 service agent. <br />Vessel has a weak vacuum. Call CO2 service agent. <br />High CO2 consumption. Increased beverage sales or CO2 use. None <br />Vessel pressure (41) constantly high. See section on ‘vessel pressure too high’. <br />CO2 leak from vessel plumbing, CO2 fi ll <br />box, gas lines, and/or beverage or other <br />use-point equipment. <br />1. See “Safety”. Evacuate & ventilate room. <br />2. Locate & correct leak if possible <br />3. Call appropriate service agent. <br />Error in CO2 supplier invoice. Check CO2 usage history / pattern against <br /> supplier invoices. Consult CO2 supplier. <br />CO2 vessel will not fi ll. CO2 vessel is already full. None <br />Fill valve (30) is shut off or is faulty. Consult CO2 service agent. <br />Brass fi ll fi tting in CO2 fi ll box and/or on <br />truck’s delivery hose is faulty. <br />1. Consult with CO2 supplier or service agent. <br />2. Have brass fi ll fi tting(s) replaced if needed. <br />Differential between store vessel pressure <br />and delivery pressure is too small. <br />(At start of fi ll, store vessel pressure <br />should be 110 - 150 psi and delivery <br />vessel pressure should be 275 - 300 psi). <br />1. Verify delivery vessel pressure is at least 275 <br /> psi and store vessel pressure (41) is between <br /> 110 and 150 psi. <br />2. Vent store vessel to lower pressure if needed. <br />Note: Never vent vessel pressure to lower than 110 psi. <br />Sure Fill™ assembly not operating <br />(relieving) properly <br />1. Ensure that Sure-Fill valve 32d is open. <br />2. Consult CO2 service agent. <br />Leak in Sure Fill™ assembly / regulator. <br />(Pressure above check ball is lower than <br />vessel pressure.) <br />1. Close Sure-Fill valve 33d for several minutes <br /> allowing pressure above check ball to equalize <br /> and ball to fall into the open position. <br />2. Contact CO2 supplier. <br />Delivery vessel is empty. Consult supplier. Arrange for another delivery. <br />Delivery vessel empty or truck delivery <br />hose is obstructed, e.g. vehicle stopped <br />on hose or hose is bent. <br /> Ask driver to make another delivery or clear <br /> obstruction or wait until obstruction clears.
