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.
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.
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 Halocar-
bon grease on the bottom O-ring and proceed with reassembly. Proceed
to paragraph 4.6.2, Cleaning V-Notch Plug.
4.6.2 Cleaning V-Notch Plug
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 time
float movement in the rotameter is not proportional to V-notch plug rotation
(a sudden marked rise or drop for a small amount of plug turning), the V-notch
plug requires cleaning.
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, shut off the injector water supply.
b. Manual: Remove the V-notch assembly completely from the control unit by
unscrewing the extension chamber. Unscrew the adjusting knob completely
and withdraw the V-notch plug.
Automatic: Put electric actuator in manual position as described in electric
actuator book. Rotate knob to lower actuator shaft down as far as possible.
Unscrew the clamping nut and push the V-notch up. Unscrew the V-notch
plug chamber. Unscrew the V-notch plug. Reassemble in reverse order.
