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 RESIDUAL SOLVENT MAY REACT WITH THE GAS.
SOLVENTS CAN PRODUCE SERIOUS PHYSIOLOGICAL EF-
FECTS UNLESS USED IN STRICTEST COMPLIANCE WITH THE
SOLVENT MANUFACTURER’S SAFETY RECOMMENDA-
TIONS.
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 im-
prove 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
electrostatic 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 reassem-
bly as described in Section 2 - Installation. Proceed to paragraph 4.11.4,
Cleaning V-Notch Plug.
4.11.4 Cleaning V-Notch Plug (See Dwg. 25.055.000.052)
The same contaminants seen in the rotameter are in the gas stream flowing
through the V-notch orifice and may also deposit at this point. When the
rotameter is cleaned, clean the V-notch plug at the same time. If, at any
