do Instructions FII out information about the site and tank specifications. Record test date and the name of the person who is performing the test. 1. Raise the brine level approximately 6-12" into the 4" W. standpipe. Do not overfill the standpipe. Raising the brine level into the standpipe is temporary and performed only to determine tank tightness. The standpipe is not part of, and is not employed in continuous monitoring of the tank, does not constitute part of the monitoring system and is not provided by Xerxes. In normal use, the brine will not rise to the level of the standpipe, which serves only as an access to the reservoir. In potentially cold climates, we recommend that you prepare a field -mixed brine solution. It should be a 30% table salt (sodium chloride) or equivalent calcium chloride mix. A few gallons of brine should be all that is necessary to top off the reservoir and to raise the fluid level 6-12" up the standpipe. After completing the test, if plain tap water was used to raise the fluid level, be sure to drain only the water, not the freeze- protecting brine, from the reservoir. Using a calibrated dipstick (ruler), measure and record the brine solution level. We recommend using an extended dipstick that is Site Location Address: Phone: Contact name: Test date: Person performing test: 95/5% Test calibrated in 1/8" increments. The more accurate the measurement, the better the chance for an accurate tank tightness test. Check the brine level twice and record on Line 1 A or 1 B. 2A. If you are performing a 95/5% test, wait 4 hours, check the brine level and record on Line 2A. Note the dispensing rates for product during the test at the bottom of the chart. 28. If you are performing a 99/1 % test, wait 10 hours after the initial measurement, check the level, and record the measurement on Line 2B. Note that no dispensing of product is allowed during this extended test. 3. Subtract line 2A from 1 A, or 2B from 1 B. Enter result on Line 3. 4. Multiply result on line 3 by the calibration factor on Line 4. 5. Enter the result of Step 4 on Line 5. 6. Divide by the number of hours in the test. 7. Enter the result of dividing Line 5 by Line 6. If the result is 0.05 gal./hr. or less, the tank has passed the test. Keep the completed test form in your permanent records. 1A. Start level (inches in standpipe) ................. 2A.

Note: Test results are invalid and the test should be repeated if the ground water level is above the bottom of the tank but below the top, and if the ground water level increases by more than 3" during the 4 -hour test or more than 7" during the 10 -hour test. If the ground water level is above the top of the tank, these numbers should be 2" for a 4 -hour test and 5" for a 10 -hour test. CORPORATION
