TM 10-4610-244-13 TM 09476B-13/1 1-9.  EQUIPMENT DATA.  Refer to Table 1-1 for performance data on hypochlorination unit Table 1-1. Equipment Data. SHIPPING WEIGHT 175 lbs DIMENSIONS Width 24 3/4" Length 39 3/4" Height 26 1/4" MAXIMUM PRESSURE 125 psi. MAXIMUM FLOW RATE 350 gpm. MAXIMUM OPERATING TEMPERATURE  140°  F (60°C). MINIMUM OPERATING TEMPERATURE 32°  F (0°C). SECTION III.  PRINCIPLES OF OPERATION. 1-10.    THEORY  OF  OPERATION.    The  hypochlorination  unit  chlorinates  water  and  is  used  in  conjunction  with  water storage  and  distribution  systems  It  consists  of  several  simple  parts  combined  into  one  unit,  and  may  be  used  in  the system  before  or  after  storage  tanks.    Primary  component  is  the  proportioning  pump  of  which  upper  housing  and pumphead assemblies are shown.  Rotary motion of the flow meter (not shown) is used to turn cam (I) Cam pushes and releases valve arm (2) When valve arm (2) is pushed completely by cam, it pushes on R-valve (3) and shuts it.  After R- valve (3) is shut, the valve arm (2) then pushes on the bal-valve (4) to open it.  When the bal-valve (4) is open, water from the lower housing assembly flows through the hole (5) and pressurizes upper housing assembly.  This pressurized water passes through a pipe to the pumphead assembly where it pushes on the water side diaphragm (6).  The pressure overcomes  spring  pressure  pushing  the  chemical  diaphragm  (7)  which  pumps  calcium  hypochlorite  out  the  discharge valve  (8).    When  the  cam  (1)  releases  valve  arm  (2),  spring  pressure  allows  bal-valve  (4)  to  shut  and  R-valve  (3)  to open.  The R-valve (3) discharges water to environment.  When water pressure is no longer on water side diaphragm (6), spring pressure pushes diaphragm to original position and pulls chemical side diaphragm (7) away from pump housing causing calcium hypochlorite to be drawn through suction valve (9).  The cam (1) continues to turn and repeat this action as long as there is flow through the water meter. 1-5
