For the two-inch variable throat injectors, two-inch polyethylene pipe or
two-inch rigid PVC pipe is normally used. Solution hose may be connected
directly to the injector tailway. If rigid PVC pipe is used, a piece of straight
pipe at least 12 inches long should be coupled to the end of the injector
tailway before any elbows, tees, or Saunders valves are used. This is to
prevent any flow disturbances that could affect the hydraulic performance
of the tailway. Discharge in an upward direction.
2.13 Point of Application
2.13.1 Main Connection
If the solution is to be applied in a main, a suitable pipe tap is required in
the main to accommodate the solution tube or diffuser.
2.13.2 Open Well
If the solution is to be applied in a basin, flume, channel, etc., where there
is no pressure, the line from the injector must be supported so that the open
end is submerged to the bottom of the chamber, or a minimum of six feet,
if possible, and is located in a nonstagnant area.
2.14 Vacuum Regulator
A vacuum regulator (or vacuum regulator-check unit), which is a gas
pressure reducing valve (and check), is connected to the control module
inlet. Refer to the separate instruction book supplied with the unit for
installation instructions for the unit.
2.15 Leak Check
After the vacuum regulator(s) (or vacuum regulator-check unit) are in
place, and before the gas tubing or piping that will connect it to the control
module is installed, check for gas leaks as directed in the separate instruc-
tion book provided with the vacuum regulator.
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY
OR EQUIPMENT DAMAGE, DO NOT TOLERATE ANY CHLO-
RINE LEAKS. LEAKS ALWAYS GET PROGRESSIVELY WORSE
AND MUST BE CORRECTED PROMPTLY.
NOTE: The vacuum line extending from the control module to the
vacuum regulator must not exceed the distance as determined through
the use of the graph shown on Dwg. 25.052.190.030 for the standard
tubing and pipe sizes given. If necessary, any tubing or pipe can be
