Correcting Air-Bound Unit After Startup.(4) Run unit for 10 minutes and take residual test, para 2.5.5.7.(5) Continue adding water and repeating tests until desired residual is obtained.1. If residual reading is low:(1) Turn stroke adjust thimble (Figure 2-47, 1) setting to 7.5 on micrometer bar scale (2).(2) Run unit for 10 minutes and repeat residual test, para 2.5.5.7(3) If reading remains low, continue to adjust stroke setting up and perform residual tests untildesired residual is obtained.m. When residual test, para 2.5.5.7 gives desired reading, no adjustments to unit are required. Checklevel of solution in reservoir every 30 minutes. When level drops within 2 or 3 inches of foot valve(Figure 2-45, 4), prepare new batch of solution in reservoir (2).n. Make residual tests para 2.5.5.7 at frequent intervals to see if desired residual is being maintained.Over an extended period of time, unit requires some adjustment, steps k. or 1. above, to keepresidual at desired level. o. To stop unit, close range adjusting valve (Figure 2-46, 1).Hypochlorination unit will not operate when there is no flow through water meter.2.5.5.5 OperationofHypochlorinationUnit:Model1955-3 .Reference applicable technical manual foroperation of hypochlorination unit model 1955-3.2.5.5.6 Operation of Hypochlorination Unit: Model A-506131.
