Maintenance Procedures <br /> Please note that item numbers on this sheet corresponds with the item numbers on the <br /> Maintenance Checklist. Most of the maintenance requirements and procedures are also <br /> covered in the Convault owner's manual. <br /> Weekly Checks: <br /> I.. If leak detector indicates fluid in the interstice,remove any devices and determine what the <br /> fluid is. Call your Convault representative. <br /> 2. If leaks are detected,contact the appropriate authorities as necessary. Tighten,repair as <br /> necessary, replace components, or contact your installer or service company. <br /> 3. if paint or powder coating deterioration occurs on nipples, spill containment or manholes, <br /> clean to bare metal,prime with a good quality zinc based primer, and repaint. If corrosion <br /> is severe, contact your Convault representative as soon as practical. <br /> 4. If dispenser meter is not working or will not reset, call your service company or installer. <br /> 5. if the fuel gauge fails to operate properly, repair/replace it, or call your service company <br /> before the next delivery. (It is the owner/operator's responsibility to prevent the <br /> overfilling of the tanks. The gauge is part of the required system to prevent overfilling.) <br /> If the Kroger cap has deteriorated, it could be allowing rainwater into the primary tank and <br /> should be replaced. <br /> 6. Keep spill containment clear of debris at all times. A contaminated spill containment will <br /> cause the fuel to be contaminated when any spill is released through the drain into the <br /> primary tank. Materials such as rags or paper products used to clean the spill containment <br /> must be disposed of properly, as they will usually contain fuel from the spill containment. <br /> 7. if there are small cracks in the concrete, fill and repair them. If you have questions, call <br /> your local Convault representative. <br /> S. If signs or decals lose visibility, order replacements from your local Convault <br /> representative before the next time the tank is filled. <br /> Monthly: <br /> 9. If there is water in the tank it will collect at the bottom,under the fuel. Water in the tank <br /> will cause increased corrosion. If you discover water in the primary tank it must be <br /> removed. One method is to pump it out with a"Thief Pump", a small pump that pulls the <br /> water from the bottom 1/9" of the tank. Check tank openings for possible water entry <br /> points. If you find that you are pumping out more than one half gallon of water for every <br /> 1000 gallons of product stored, see your fuel dealer, or call your Convault representative. <br /> Also consult item (1)in the maintenance section of the owner's manual. <br /> 10. If you detect leakage, determine what the liquid is, if possible,and call your Convault <br /> representative and appropriate authorities as necessary. <br /> 11. if there are problems with the leak detector tube or lock, clean and lubricate them as <br /> necessary. Sec item(G)in the maintenance section of the owner's manual. If the Kruger <br /> leak indicator does not function properly,remove it and repair or replace it. Due to <br /> ultraviolet radiation, the clear cap on the Kruger leak indicator will deteriorate over time. <br /> If it has deteriorated, it could be allowing rainwater into the interstitial area and should be <br /> replaced. New caps and rings or entire units can be purchased from Kroger, your service <br /> company, or your Convault representative. Kruger now offers a guard, which will <br /> prolong the life of the cap. If electronic leak detection test fails, call your service <br /> company. <br /> P U1 888-965-3227 <br /> �M�owi' r convaultmm <br />
