English
Use FreshWater Salt Test Strips to
verify the salt level is around 1,750
ppm. Continue to add salt, one cup at
a time, as needed to reach the target
level. Be careful to not exceed the
recommended target of 1,750 ppm.
Step 4 - Balance Water
Test your water using a FreshWater
5-Way Test Strip (Reference Table
2). Review pH and alkalinity levels
to determine if your water is within
the salt system’s parameters and
adjust as needed. Make note of the
calcium hardness level as this will be
addressed in step 6. Refer to your spa
owner’s manual for detailed
instructions on how to bring
pH and alkalinity levels into
balance. Once the water has
been balanced, retest the
water using the 5-Way Test
Strip. Repeat the process until
the water is balanced.
Step 5 - Sanitize Fill Water
With all jets on and the diverter valves turned to the middle position, add chlorine to the
filter compartment (refer to the product label for instructions). Run jets for 5 minutes and
measure the chlorine with a new FreshWater 5-Way Test Strip. Your target chlorine level is
5 ppm. If your level is less than 5 ppm repeat the chlorination process. Wait 5 minutes then
test again. Repeat until the target level of 5 ppm is reached.
NOTE: If using liquid chlorine - DO NOT USE "splash free” or scented bleach of any kind.
NOTE: It is very important that you shock the spa water with chlorine at start-up.
Skipping this step can prevent the system from establishing a chlorine residual.
Shock is a process of adding doses of a quick-dissolving chlorine to oxidize non-filterable
organic waste and to remove chloramines and bromamines.
Step 6 - Soften Water
NOTE: Include this step if you did not use a calcium remover during the fill process
(in Step 2).
Hard water can damage your hot tub equipment and may hinder the effectiveness of the
salt system, so it's important to make sure your water is soft. Your target calcium level is 50
ppm. Use the following guidelines if your calcium hardness is over 75 ppm:
