8. Inspect the exposed floats for freedom of <br />movement ordamage. These floats should slide <br />back and forth onthe guide bar freely. |fthere <br />imany binding, the guide bar may bmbent. |f <br />necessary, straighten this guide bar (see Figure D). <br />Q. Inspect the linkage connecting the floats tothe <br />valve operating mechanism. This linkage should he <br />clean and intact (see Figure D). <br />Figure D <br />10. Insert the 1/8"T-hendledhex wrench into the open <br />hole until itmakes contact with the internal valve <br />flapper (see Figure E). <br />Figure E <br />11. While holding both floats from sliding away from <br />the inserted hex wrench, lightly try topush the hex <br />wrench further into the hole. The flapper should <br />stay inthe locked position and not move closed. <br />|fthe flapper closes, the latching mechanism |m <br />defective and valve must be nop|moad. <br />12. Slide the float closest to the hex wrench away from <br />the wrench. You should now beable hoeasily push <br />the hex wrench further into the hole. This will close <br />the first stage valve flapper (see Figure F). <br />13`With the hex wrench inserted until itwill not goany <br />further, the first stage valve flapper should stay in <br />the closed position. Using a flashlight, you can now <br />see this bylooking |nfrom the top ofthe drop tube <br />(see Figure G). <br />Figure G <br />14. Slide the second float away from the hex wrench <br />(see Figure H).This will release the valve's second <br />stage flapper (see Figure 1). <br />Figure I <br />15. Remove the hex wrench from the inspection port. <br />The valve's internal flappers should return totheir <br />open positions. Toverify that the flapper has reset <br />and rm-|atohed're-insert the hex wrench and repeat <br />Steps 10 &11.|fthe flapper did not reset, replace <br />the valve. <br />ENVIRONMENTAL <br />
