Your 32,000 grain softener, 1 Cu. Ft. of resin should not be run at 30,000 grains, this will waste a large amount of salt. Use the programming guide. This will give you a good balance of salt and water efficiency, while maintaining high quality soft water.
Adjust the programming above to fill first. Potassium chloride tends to bridge in the salt tank due to its higher variance in solubility at varying temperatures. Sodium Chloride will vary approximately 1% for every ten degrees of temperature change, potasium Chloride will vary approximately 10% for every ten degrees. In a location where the temperature varies more than 10 degrees between regenerations, caking is a common problem with potasium. A garage in Phoenix can change from 60 degrees at night to 120 degrees during the day. The extra potassium is absorbed into the water, then as the temperature drops, the potassium comes out of soultion and precipitates into a cake. Here is a link to great article written in 2005 addressing this issue.

Hope this helps, and your Clack WS-1 system will serve you well for many years without fail, congratulations on buying a great unit!
