2. Total water hardness.
<br />To determine the daily capacity requirement, multiply the
<br />daily water usage by the water hardness. For example, if the
<br />water hardness is 21 grains per gallon, and the water usage is
<br />3000 gallons per day:
<br />Capacity required (grains) = 21 gpg x 3000 gpd
<br />= 63,000 grains/day
<br />Timeclock Units
<br />With the daily capacity requirement known, refer to Table
<br />4A and 413 to determine the required salt dosage and refill
<br />minutes. Using the above example with PV -90A softener,
<br />the unit would regenerate daily with a 20 pound salt dosage
<br />and a 9 minute refill time.

<br />Units with Aqua--ensor® Sensing Device
<br />For units with the standard, delay -style Aqua -Sensor sensing
<br />device, the reserve capacity must last an entire day if the
<br />Aqua -Sensor probe signals the need to regenerate at the
<br />beginning of the day. Therefore, the reserve capacity should
<br />be approximately equal to the daily capacity requirement.
<br />Refer to Tables 5A and 513 to determine the salt dosage and
<br />refill time necessary to obtain the required reserve capacity.
<br />NOTICE: The capacity to signal is equal to the total capac-
<br />ity from Table 4A or 4B minus the reserve capacity from Table
<br />5A or 5B.
<br />NOTICE: Capacities shown are nominal and based on resin
<br />manufacturers data. Actual capacity will vary with the
<br />influent water characteristics, temperature, flow and other
<br />factors.
<br />Duplex Units
<br />The capacities for duplex units are the same as for single
<br />units. However, if both units regenerate every day, there may
<br />not be enough time to produce saturated brine in the single
