b. If the main is smaller than eight inches, install the tailway in a tee, in a
striaght run section of the main.
c. Where the injector is to be some distance away from the point of applica-
tion, use adapters to connect to pipe or corporation cock type main con-
nections, check valves, etc. Your dealer can provide whatever components
are required.
d. Where the injector is not installed directly into the application main, wall
mounting of the injector may be required. To install the injector on a suit-
able wall, use the bracket holes as the drilling template. Secure the injector
to the wall.
e. The injector nozzle (black color with number size designation) is designed to
accept 3/4-inch polyethylene tubing or 3/4-inch threaded pipe connection.
For pipe thread connection, cut off the serrated section with a hacksaw
and bevel the sharp corners at the ID and OD. Ensure that the interior of
the nozzle is free from burrs or chips before installing it in the injector.
NOTE: The polyethylene tubing is suitable for pressures up to 75 psi. Pressure
in excess of 75 psi requires rigid pipe.
f. The nozzle and the tailway are sealed to the injector body by means of
O- rings. Hand tightening is sufficient. Do not use a wrench or attempt to
tighten beyond that point where the shoulder on the fitting touches the
body of the injector. If the injector is not oriented as desired when fully
installed over the tailway, use a suitable tool to turn the tailway with respect
to the main (or next fitting in the assembly) until the orientation is proper
with the gas inlet side on top or most accessible face.
g. Install connection to water supply or to a booster pump, if required. The
water supply valve can be a manual valve or solenoid valve. A water supply
strainer is recommended. The water supply must be reasonably clean. If
the injector is to be operated using clarified effluent, such as in a sewage
treatment plant, use larger sizes of nozzles and tailways to minimize the
likelihood of plugging.
To install the one-inch fixed throat injector, proceed as follows:
a. The nozzle and the tailway are sealed to the injector body by means of
O- rings. Hand tightening is sufficient. Do not use a wrench or attempt to
tighten beyond that point where the shoulder on the fitting touches the
body of the injector. If the injector is not oriented as desired when fully
installed over the tailway, use a suitable tool to turn the tailway with respect
to the main (or next fitting in the assembly) until the orientation is proper
with the gas inlet side on top or most accessible face.
