b)
Operate the Chlorine Valves. Open and close all chlorine valves
each day to ensure proper and complete operation. Do not use force in closing a
valve. Repair or replace any faulty valves at once.
c)
Check the Water System. Each month, clean the water strainers
and check the pressure reducing valve for proper operation. Clean the injector nozzle
and throat once a year. (Insufficient injector vacuum usually indicates that cleaning is
required.) Muriatic acid may be used for cleaning mineral deposits from the injector
nozzle and throat.
