1.10.4 Arctic Spas Onzen™ Salt Dose Guidance Table
The following table identies the salt quantity required for each Arctic spa model and estimated impact of adding
half pound (225g) of salt. For startup, it is recommended to strive for the minimum salt dosage. Once a Sodium
Chloride reading has been taken and the minimum salt dosage achieved, it can be increased slightly to accom-
modate spa usage and bather load, if increasing the Onzen run time does not adequately increase the Chlorine
Residual. Having the minimum amount of salt concentration unless the Onzen system is unable to maintain the
proper Chlorine residual, will reduce potential corrosion and increase the life of the Onzen Output Electrode.
NOTE: The above table provides a guideline to achieve a salinity level of 2200 ppm. Due to diering levels of
compounds and chemicals in water in dierent suburbs and countries, please ensure you conrm salinity level
is in the desired salinity range using Aquacheck Salt Test Strips
