*Any V3162-XXX fl ow control may be used. WS2 valves are
shipped with a V3162-022 (2.2 gpm) fl ow control. Flow control
sizes range from 0.7 up to 10 gpm. WS2 valves can only be set for
minutes of fi ll because various sizes of fl ow controls can be used.
To calculate for pounds or kilograms of salt, take minutes of fi ll
times the fl ow rate of the fl ow control being used to arrive at the
number of gallons of water be added to the brine tank. Each gallon
of water will dissolve approximately 3 pounds of salt.
**Use of H4915 may severely reduce brine draw rates.
