8.7.2. Once the tank is installed, the level of the monitoring fluid may fluctuate due to such things as: • product level • groundwater fluctuation • tank filling and emptying • product -temperature variation 8.7.3. To establish the proper operating level for monitoring fluid, decide what type of monitoring probe will be used in order to determine the initial starting point for the level in the reservoir. 8.7.4. Observe the following instructions when using a probe: • Do not raise it off the tank to meet the monitoring -fluid level. • Keep the probe upright and in contact with the top of the tank at all times. See Figure 8-1. • When using a two -sensor probe (typical probe with a high -fluid level and a low -fluid level), the starting point (the proper level for the monitoring fluid) is midway between the two sensors. • If using something other than a two -sensor probe, use 7 inches [18 cm] from the top of the tank as the starting point for the monitoring -fluid level. • After determining the starting point, adjust the monitoring fluid based on the product level. • If the tank is between 1/4 and 1/2 full of product, the proper operating level for the monitoring fluid is at the starting point. • If the tank is between empty and 1/4 full, the proper operating level forthe monitoring fluid is about 1 inch [3 cm] below the starting point. • If the tank is between 3/4 full and full, the proper operating level forthe monitoring fluid is about 1 inch [3 cmJ above the starting point. • Add or remove monitoring fluid to reach the proper operating level forthe monitoring fluid.

If a TRUCHEK testis required after installation, follow the procedures in the TRUCHEK brochure. • After this test, reset the monitoring -fluid level to a position based on the product level. 9: OPERATING GUIDELINES 9.1. GENERAL 9.1.1. Owner must retain the Installation Manual and Operating Guidelines for future reference to operating guidelines. 9.1.2. In addition to this Installation Manual, follow all laws, regulations, codes and safety precautions of appropriate governmental agencies that pertain to underground storage tanks and/or their associated systems. 9.1.3. Consult supplemental materials (see the Introduction), tank brochures, separate product instructions (such as oil/water separators) and separate accessory instructions, which are available upon request from the manufacturing facility that shipped the tank. Most of these documents are also available at zcl.com and through technical support. 9.1.4. Consult the applicable limited warranty for further operating guidelines and limitations. A copy of our current limited warranty is found atzcl.com.The tank owner should retain the limited warranty. 9.2. TEMPERATURE LIMITS FOR STORED PRODUCTS AND MATERIALS 9.2.1. Each tank is designed to store products and materials identified in the manufacturer's applicable limited warranty. NOTICE Products and materials must be stored in the tank appropriate for the specific product or material. Failure to follow this notice could result in damage to the tank and/or surrounding property. NOTICE Storing products and materials other than those identified in the manufacturer's applicable limited warranty will void the tank manufacturer's obligations under the limited warranty and could result in tank failure and/or damage to surrounding property. 9.2.2. The temperature of stored products and materials must not exceed the temperature specified in the manufacturer's applicable limited warranty. NOTICE Introducing or storing a product or material into a tank in excess of the allowable temperature could damage the tank. Failure to follow this notice could result in damage to the tank and/or surrounding property. NOTICE Care should be taken not to allow accumulation of water inside the containment sumps, as it can freeze during winter conditions and result in damage to tank and property. 9.3. ENTERING TANKS 9.3.1. Do not allow anyone to enterthe tank unless it has been properly emptied and vented, and unless the person entering the tank has been trained in confined -space entry procedures and applicable OSHA regulations or appropriate Canadian federal and provincial regulations. A WARNING Improper tank entry could cause fire, explosion or asphyxiation, and could result in death or serious injury. 27
