All traces of solvent and moisture must be removed from parts which come
in contact with the gas before being returned to service. Do not use heat on
plastic or hard rubber parts.
4.6.1 Cleaning Rotameter (See Dwg. 25.100.150.010)
If a milky white, powdery white, green slimy or brown oily deposit is visible
inside the rotameter tube or if the float has particles clinging to it or tends to
stick to the tube wall at lower feeds, it is time to clean the rotameter. Proceed
carefully to avoid dropping the glass tube or losing the float down a floor drain
or grating. Have a clean cup (such as a coffee cup or a small beaker) and a pair
of tweezers at hand before starting. Proceed as follows:
a. Turn the knob on the vacuum regulator(s) to the OFF position. After the
supply vacuum gauge reads full scale and the rotameter float rests on the
bottom stop, turn off the injector operating water.
b. Exert downward force on lower bell of rotameter with one hand. Use two
fingers of other hand to swing the top of rotameter outward. Lift rotame-
ter. Take care not to lose the end stops or the float. Discard the removed
O-rings.
c. Place the end stops and float into the cup mentioned above.
d. Many (but not all) 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 or stoppers 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 inte-
rior. A detergent will promote cleaning action.
WARNING: DO NOT USE HYDROCARBONS OR ALCOHOLS BECAUSE
RESIDUAL SOLVENT MAY REACT WITH THE GAS. SOLVENTS CAN PRO-
DUCE SERIOUS PHYSIOLOGICAL EFFECTS UNLESS USED IN STRICTEST
COMPLIANCE WITH THE SOLVENT MANUFACTURER’S SAFETY RECOM-
MENDATIONS.
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
