TM  10-4610-244-13 TM  09476B-13/1 2-10.  OPERATING PROCEDURES (Cont'd). q.  If residual reading is too low, turn stroke setting up to 8 (1)   Allow unit to run for another 30 minutes, then repeat residual  test (refer to step c for details of procedure). (2)   If reading remains low, raise stroke setting  to 10. (3)   If reading remains low after another 30 minutes double check estimate of flow rate to ensure that range adjusting valve is in correct position.  Also, make sure that water pressure is greater than 15 psi. (4)   If  range  adjusting  valve  is  in  correct  position  and  residual  reading  still  remains  low,  increase  solution strength by adding enough calcium hypochlorite to raise one ppm per Table 2-2.  If already at 10 ppm, add 10 ounces for 350-70 gpm, 37 ounces for 15-70 gpm or 0.8 ounces for 2-15 gpm. (5)    After desired chlorine levels are reached, go to Step r r Fill reservoir (1) with remaining by hypochlorite solution from mixing  bucket. s Place cover on reservoir.  No other action is required other than periodically  sampling  in  accordance  with  TB- MED-577 and FM 10-52-I and refilling reservoir as necessary, referring to steps g through I for mixing instructions Hypochlorination  unit  should  be  able  to  produce  following  amounts  of  water  from  one  reservoir  full  of,  solution (based on control valve being set at 5). Setting A; 58,600 gals Setting B: 19,600 gals Setting C: 3,600 gals 2-14
