TM 5-6630-218-10 2.5.7 Taking a Sample a. Hold the sampler in an upright (vertical) position, turn the three- way valve to the TEST position: when the valve arm is positioned at a right angle to the base of the valve (vertical) (Figure 2.34). Figure 2.34 Three-Way Valve - TEST Position b. Allow 500 milliliters (17.0 ounces) or less of fuel to pass through the assembly and free-water test pad. Record sample volume for reporting. c. When collection is completed, turn the three-way valve to the OFF position before turning off the system pump. CAUTION Some pumping systems (e.g. aircraft refuelers) develop a vacuum when closed which can cause backflow and rupture the monitor filter, rendering the test ineffective. d. Retract the quick-release valve collar and remove the sampler nipple from the valve. Replace the protective cap and plug. See Figure 2.13. e. Disconnect the bypass hose from the side of the sampler and unscrew the sampler base. Hold the sampler in an upright position and remove the stainless steel monitor (Figure 2.35). 2 - 3 7
