4 .5.2.2 Torque.  The hypochlorinator shall be disconnected from the water
meter and the torque required to turn the shaft of the hypchlorinator shall be
determined with a torque wrench.  Measured torque greater than 8 inch-ounces
shall constitute failure of this test.

Test setup shall be as follows:
4. 5.2.3.2
Test setup and procedure.
Connect the unit to a source of tap water capable of delivering not less
a.
than 350 gpm at 125 psig so that the flow enters the inlet end of the
4. inch line and leaves at the outlet end.
Flow rates shall be set with calibrated rotameters, or the discharge
b.
shall be caught in a container of Known volume or weighed if desired.
c.
A single adjustment of the range valve shall be made for each of the
conditions shown in table I.
provide a means of measuring total Waste flow from the diaphragm pump.
d.
Set up a 1,000 cubic centimeter (cc) graduate (divided every 2 cc) as
e.
a solution reservoir and fill with water.  Place on a support so that
the water level, when full, is at the same eievation as the liquid
level in the solution container when full.
Do not immerse
Remove suction tubing and attach to botton of graduate.
f.
tubing in an open top graduate.
Adjust the dosage control to maximum setting.
