a. Turn the knob on the vacuum regulator(s) to OFF. After the supply vacuum
gauge reads 100 inches of water and the rotameter float rests on the bot-
tom stop, turn off the injector operating water.
b. Remove rotameter. Take care not to lose the end stops, the float, or any
of the O-rings. See Dwg. 25.055.151.010.
c. Place the end stops and float into the cup mentioned above.
d. Many gas contaminants are soluble in water. Hold the tube end under
running warm (110-125°F) water so that the water enters the tube at one
end and exits at the other to flush out deposits. Alternately, soak the tube
in a container of warm water for about 30 seconds. Then hold the tube,
half full with water, with palms capping the ends, and shake vigorously
endwise for a few seconds. Discharge the water and repeat until clean. A
common pipe cleaner may be used to scrub the interior. A detergent will
promote cleaning action.
WARNING: DO NOT USE HYDROCARBONS OR ALCOHOLS BECAUSE RESID-
UAL SOLVENT MAY REACT WITH THE GAS. SOLVENTS CAN PRODUCE SERI-
OUS PHYSIOLOGICAL EFFECTS UNLESS USED IN STRICTEST COMPLIANCE
WITH THE SOLVENT MANUFACTURER’S SAFETY RECOMMENDATIONS.
e. Drain and let dry. Do not use a pipe cleaner as a drying tool because the lint
from it will stick to the tube interior. Place the tube at an angle between a
horizontal and a vertical surface (as between a shelf and a wall) with both
ends open so air can flow through. Drying will be hastened by heat, as
from a light bulb nearby. Do not blow through the tube as moisture from
the breath will condense on the tube walls.
f. To clean the float, pour about an inch of warm to hot (130-150°F) water
into the cup containing the float. Grasp the float with tweezers and shake it
side to side while submerged for a few seconds. Release the float and pick
it up again and repeat the action several times so all surfaces are washed.
Hold the float with the tweezers, discard the wash water, and repeat the
above. A few drops of detergent will improve the process. Do not use your
fingers to hold the float.
g. Allow the float to dry on a clean surface and then, with tweezers, place it
in a clean, dry cup.
NOTE: Do not attempt to dry the float with a rag or paper towel, as electro-
static forces will make lint and other particles stick to the float.
h. Clean stops with water and dry thoroughly before reassembly.
i. When tube, float, and stops are clean and dry, wipe a thin film of Halocarbon
grease on the bottom O-ring and proceed with reassembly as described in
Section 2 - Installation. Proceed to paragraph 4.11.4, Cleaning V-Notch Plug.
