NOTE: Vacuum leaks ahead of the rotameter as listed in step d, above, will
result in errors in gas feed. Vacuum leaks after the rotameter, as listed in step
e, may impair the performance of the injector.
f. Close V-notch plug all the way (clockwise).
3.2 Operation
NOTE: The following procedure assumes all preparatory steps and leak tests
have been completed.
3.2.1 Starting
a. Turn on the gas supply at the supply container valve and the vacuum regu-
lator. If there are two units (automatic switchover system), turn on only
the one on the supply container that is to be used first.
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR EQUIP-
MENT DAMAGE, DO NOT OPEN THE GAS SUPPLY CONTAINER VALVE
MORE THAN ONE COMPLETE TURN. THIS WILL SUPPLY SUFFICIENT GAS
TO OPERATE THE EQUIPMENT AND CAN ALSO BE TURNED OFF QUICKLY
IN CASE OF A GAS LEAK.
b. Turn on the water supply to the injector.
c. Adjust the gas feed rate as desired. Counterclockwise rotation of the
control knob increases the feed rate.
d. If there are two vacuum regulators, turn on the gas supply at the second
supply container and vacuum regulator.
3.2.2 Stopping - For Short Periods
Turn off the injector water supply.
3.2.3 Stopping - For Extended Periods
a. Turn off the gas supply at each supply container valve and at each vacuum
regulator.
b. Wait until the supply vacuum gauge reads full scale, and the rotameter
float rests on the bottom stop, then turn off the injector.
3.2.4 Intermittent Start-Stop Operation
Operation of the gas feeder in synchronism with a pump or other apparatus
may be accomplished by installing an electrically operated solenoid valve in
the injector water supply line and connecting it so the valve is open when the
pump is running and closed when the pump is shut down.
