Educational Information

*60 gallons per person per day - Total Household Usage or K label capacity
*Number of people X 60 gallons per person X gpg of hardness X 3 days = capacity   required between regenerations
*Consult your factory representative for water that is 75 gpg or harder
*(Note: for high volume households, use 75 gallons per day per person)
 

Hardness Compensation

* 1 mg/l of iron = 4 gpg
* 1 mg/l of manganese = 8 gpg
* Maximum iron is not to exceed 1.5 mg/l total iron
* Recommend the addition of a Res-up feeder when total iron exceeds 0.5 mg/l
 

Water Softener - Iron Removal Combination Units

* This unit should be recommended only when dictated by special circumstances    or the needs of the customer
* The customer should be aware that a separate iron filter and softener is    preferred because it is a more efficient way to deal with the water
* When a combination unit is recommended, follow the guidelines provided in the    specifications
 

Water Consumption for Regeneration

The volume of water used during the regeneration process of a water softener will vary depending on:
* Amount and type of resin
* Cycle time settings
* Flow controls
* Salt settings
* Tank diameter
 
Generally, water usage for regeneration is based on the cubic feet of resin per water softener from a low of 30 gallons of water per cubic foot, to a maximum of 100 gallons of water per cubic foot. Manufacturing specs and settings for each model size should be checked to verify exact amounts.
 

Three Day Sizing Method

1. To determine the size of the water softener required.
2. To allow for reserve capacity between regenerations so the customer does not    run out of soft water.
3. To provide the most economical operation cost.
