through before it needs to regenerate). To calculate this number you will need to know the system
capacity, (for example, a 48k system has a 48,000 grain capacity) and the hardness of the water in grains
per gallon (GPG). If your test shows hardness as parts per million (ppm) or milligrams per liter (mg/l)
simply divide by 17.1 to get grains per gallon. Take the capacity of the system and divide by this number,
this is your total capacity. Multiply the number of people in the house by 75, this is your reserve
capacity. Subtract the reserve capacity from the total capacity and this is how many gallons you will set
your system to. The gallon capacity of the system is denoted by a gear with the numbers 1-21, these
numbers represent the number of gallons x 100 that you system is set to regenerate at. To set your
system, pull out the capacity knob and rotate the knob until the correct number is lined up with the
white dot. As an example, if the water hardness is 24 GPG and you have a 48k system with 3 people, your
gallon capacity would be (48,000/24)-(75x3)=1775 gallons. You would line the white dot up between the
numbers 17 & 18. If unsure of the size of your system you may contact us for assistance. Be sure to
include the name the system was ordered under when contacting us. If your water is extremely hard or
if you have high water use a larger reserve capacity may be needed.
To set the time, locate the 24 hour time gear (the large gear located behind the manual cycle knob) and
note the current time arrow. Push the red time set button in and rotate the 24 hour time gear until the
current time arrow lines up with the current time of day. A white arrow will point at the current gallon
capacity remaining. Once the countdown reaches zero the system will run a regeneration cycle that
night at midnight or 2 AM (depending on the system, the time is usually indicated on a label located on
the back of the valve). During regeneration there should be no water being used, and the default time is
usually #ne for most homes. To have it run at a di!erent time (for example if you work late and are up
and using water at the default time) you will need to adjust the current time of day to trick the system
into doing so at the desired time. For example: if the system is set to run at 2 AM and you want it to run
at 8 AM, set the current time of day 6 hours behind, that way the system will think it is 2 AM when it is

Many homeowners install their own water systems with basic plumbing
skills; if you are not comfortable with projects like this, please hire a professional plumber. Make sure to
check local plumbing codes and follow any codes that apply. These intructions o!er basic plumbing tips
