(2) At any tubing connector or pipe fitting in the gas supply line. This
may be corrected by tightening the connector or fitting, or by
replacing any defective connector O-ring.
f. Check the following to be sure all connections are tight:
(1) The V-notch extension chamber through which the V-notch plug
travels.
(2) The gasket at the bottom of the differential regulating valve.
(3) The connection of both ends of the plastic tubing on the gas dis-
charge 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 rota-
meter, 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
regulator. 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. The feed rate will be regulated by the control device. Dosage adjust-
ments permit matching the desired feed rate to the flow signal.
d. For automatic switchover systems, turn on the gas supply at the sec-
ond supply container and vacuum regulator.
