NOTE: Vacuum leaks ahead of the rotameter (as listed in preceding
step c) will result in errors in gas feed. Vacuum leaks after the rotameter (as
listed in step d) may impair the performance of the injector.
3.2.3
Gas Supply Check for Leaks
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR EQUIP-
MENT DAMAGE, DO NOT TOLERATE ANY GAS LEAKS. LEAKS ALWAYS GET
PROGRESSIVELY WORSE AND MUST BE CORRECTED PROMPTLY.
After the vacuum regulator unit(s) is in place and before the gas tubing which
will connect it to the control unit is installed, check for gas leaks as directed in
the separate instruction book provided with the vacuum regulator.

Operating Procedure
3.3.1
To Start
a. Open the point of application and the injector operating water valves.
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 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 which is to be used first.
c. Turn the feed rate adjuster knob counterclockwise (unscrew) to obtain
maximum feed. The injector should develop a dynamic vacuum of at least
six inches of mercury at maximum gas flow rate. If maximum indicated feed
rate cannot be obtained:
(1) Ensure that no vacuum leaks exist. Refer to paragraph 3.2.2, Injector
Vacuum and Leak Test.
(2) Refer to paragraph 4.9, Troubleshooting.
d. Adjust the gas feed rate as desired. Rotation of the knob counterclockwise
increases the feed rate.
e. Check that the vacuum gauge pointer is in the green sector.
f. If there are two vacuum regulators, turn on the gas supply at the second
supply container valve and vacuum regulator.
