(3) The connection of both ends of the plastic tubing on the gas discharge
line to the injector.
NOTE: Vacuum leaks ahead of the rotameter, as listed in preceding step e,
will result in errors in gas feed. Vacuum leaks after the rotameter, as listed
in step f, may impair the performance of the injector.
g. Close the 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 PERMIT MAXIMUM DISCHARGE
AND CAN ALSO BE TURNED OFF QUICKLY IN CASE OF A GAS LEAK.
b. Turn on the water supply to the injector. (For two-inch injector, turn on
the injector shut-off valve.)
c. Adjust the gas feed rate as desired. Counterclockwise rotation of the control
knob increases the feed rate.
d. For automatic switchover systems, 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. (For two-inch injector, turn off the injector
shut-off valve.)
3.2.3 Stopping - For Extended Periods
a. Turn off the gas supply at each supply container valve.
b. Operate the injector until the supply vacuum gauge reads 100 inches of
water, and then turn off the vacuum regulator. Continue injector operation
for at least three minutes to remove all gas from the machine.
c. Turn off the injector water supply. (For two-inch injector, turn off the injec-
tor shut-off valve.)
