9. Once the o-ring is in place, reinsert the LLI rod through the
LLI boss just enough so that the ball oat can be reinstalled.
Before replacing the ball oat, locate the directional arrow that
indicates proper positioning on the ball surface and ensure that
the arrow is pointed up. (Refer to Figure C.3) Keeping the
base of the LLI rod inside the LLI boss but near the top of the
cylinder, slide the ball oat back onto the LLI rod over the stop
clip KEEPING THE DIRECTIONAL ARROW POINTED
UP. e LLI will not read correctly if the ball oat is installed
upside-down.
10. e stop clip may become stretched after being spread/pinched
several times. If the ball is dropped quickly down the LLI rod and into the cylinder, the force of the fall
can lodge the ball onto the clip. e stop washer will prevent the ball from becoming wedged or stuck on
the clip. Slide the washer over the stop clip after the ball oat. Do not rapidly slide the ball oat down
the LLI rod or drop the rod into place. After installing the stop washer and while the rod is still held
near the top of the cylinder, gently guide the oat ball to its proper place at the base of the rod resting
upon the stop washer.
11. Slowly lower the LLI rod into the cylinder until the hex nut is in place to be refastened. Fasten the LLI
hex nut back into the boss tightly with a 1-1/8” wrench to ensure proper seal.
12. Prior to charging the cylinder with nitrogen or relling with clean agent, exercise the LLI tape and ball
actions as described in the Operations Manual (DOC102) to ensure the LLI is operating correctly.
13 Leak test the cylinder assembly by charging with nitrogen and applying a soap solution.
