3.1 Preparation For Operation
WARNING: HAZARDOUS GAS IS PRESENT IN THIS EQUIPMENT DURING
NORMAL OPERATION. TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR
DAMAGE TO THE EQUIPMENT, READ THIS INSTRUCTION BOOK AND THE
APPROPRIATE GAS MANUAL BEFORE CONNECTING THIS EQUIPMENT TO
A SUPPLY OF GAS. OPERATION AND MAINTENANCE OF THIS EQUIPMENT
MUST BE RESTRICTED TO TRAINED, QUALIFIED PERSONNEL WHO ARE
COMPLETELY FAMILIAR WITH THESE INSTRUCTIONS.
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 injector 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.
(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.
