A. FLOAT ASSEMBLIES <br />1. Remove the probe, fuel float and water float from the <br />packing material. Place the probe on its side. <br />2. Water Float Ballast Rings: <br />Ballast rings must be added to the water float of magne- <br />tostrictive probes to ensure proper float action. The ring <br />type varies with the fluid being measured. Float ballast <br />rings are available for the following liquids: <br />Q12601-13 Ballast Ring G2 <br />used with: aviation gas, regular unleaded <br />gasoline, premium unleaded <br />gasoline, leaded gasoline, gasohol <br />Q12601-14 Ballast Ring L2 <br />used with: motor oil, toluene, xylene, <br />fuel oil #4, gear oil 90W, <br />hydraulic oil, transmission fluid, <br />turbine oil <br />Q12601-15 Ballast Ring D2 <br />used with: ethanol, jet fuel, kerosene, <br />diesel #2, methanol, M85 <br />The following liquids do not use a water float, as water is <br />not measurable in the liquid: ethylene glycol (antifreeze), <br />wastewater, windshield washer fluid, waste oil. <br />3. To install ballast ring on the water float: <br />a. Press in the three tabs on the water float mounting tube <br />which are just above the water float, and slide the water <br />float over the top of the tube. See Figures 23 and 24. <br />WATER FLOAT <br />MOUNTING <br />i TUBE <br />WATER <br />Figure 23. Water Float. <br />Figure 24.

Slide the product ballast ring over the top of the water <br />float mounting tube. <br />",' NOTE: The ballast ring must be placed over the locking <br />V► collar with the product designation (G2, L2, D2) facing <br />the bottom or flanged end of the tube. <br />c. Slide the water float over the top of the water float <br />mounting rube and press until the tabe snap to secure <br />the water float. See Figure 25. <br />"rl NOTE: To modify the water float assembly for liquids <br />where water measurement is not possible: <br />a. Press in the three locking tabe on the water float <br />mounting tube and slide the water float up off the the <br />tube. See Figure 23. <br />b. Only the water float mounting tube will be used in place <br />of the water float assembly for the products where <br />water measurement is not possible. (See Figure 28). <br />WATER <br />FLOAT <br />WATER FLOAT <br />MOUNTING <br />TUBE <br />BALLAST <br />RING <br />Figure 25. Water Float Assembly. <br />4. Turn the black plastic boot at the bottom of the probe <br />shaft 1/4 turn, and firmly pull from the probe. (See Figure <br />26, "Removal of Boot from Probe Shaft.") <br />Figure 26. Removal of Boot from Probe Shaft. <br />5. Gently slide the fuel float onto the probe shaft, magnet - <br />side up. The float should move freely on the probe shaft. <br />(See Figure 27, "Probe Assembly for Products Requiring <br />Water Measurement," or Figure 28, `Probe Assembly for <br />Products Not Requiring Water Measurement.") <br />19 <br />
