3.1 Preparation for Operation
WARNING: HAZARDOUS GAS IS PRESENT IN THIS EQUIP-
MENT DURING NORMAL OPERATION. TO AVOID POSSIBLE
SEVERE PERSONAL INJURY OR DAMAGE TO THE EQUIP-
MENT, READ THIS INSTRUCTION BOOK AND THE APPRO-
PRIATE GAS MANUAL BEFORE CONNECTING THIS EQUIP-
MENT TO A SUPPLY OF GAS. OPERATION AND MAINTE-
NANCE OF THIS EQUIPMENT MUST BE RESTRICTED TO
TRAINED, QUALIFIED PERSONNEL WHO ARE COMPLETELY
FAMILIAR WITH THESE INSTRUCTIONS.
NOTE: See Dwg. 40.300.170.010 for instructions for manual opera-
tion.
When all connections specified under Section 2 - Installation have been
made, check the gas feeder as follows:
a. If the point of application is in a main through a corporation cock or
valve, the cock or valve must be open. Push in the solution tube, if
furnished, until the end is in the center third of the main. In the case of
large mains, the tube may be pushed in as far as it will go.
b. With the gas supply container valve(s) shut off, ensure that there is
water at the point of application ready for operation.
c. Turn on the water supply to the injector with the V-notch plug closed
all the way (clockwise). (For the two-inch injector, turn the injector
shut-off valve to the ON position.) Turn on the gas supply.
d. Open the V-notch plug all the way (counterclockwise). Proper injec-
tor action may be determined by the observation of at least six inches
of mercury vacuum on the injector vacuum gauge on the control
module when the machine is operating at maximum capacity.
e. While the injector is operating and the gas supply is off, observe the
float in the rotameter. If the float is not resting on the bottom stop, a
vacuum leak ahead of the rotameter is indicated. If this is observed,
the leak may be in one of the following places:
(1) At the ring gasket at the bottom of the rotameter. This can be
corrected by proper lubrication of the ring gasket with a film of
Halocarbon grease and by ensuring that the rotameter is seated
on the ring gasket.
