Onzen Technical Guide 1.8 Definitions of Terms TERM Onzen Onzen Output Electrode DEFINITION An all-natural, salt-water softening and maintenance system. Platinum-iridium Titanium electrode - equipped salt cell converts the saltwater solution to sanitizer, and as this solution reverts back to its natural form (salt) after sanitizing. Unless large volumes of water are added to the spa you never have to add more salt. Onzen Output Electrode Version Modification status of the electrode fitted to the spa.
Onzen Technical Guide TERM Potential Hydrogen (pH) DEFINITION The pH level is the measure of alkalinity. Maintaining a Balanced pH level is extremely important for: · Optimizing the effectiveness of the sanitizer. · Maintaining water that is comfortable for the user. · Preventing equipment deterioration. · Note: Salt systems naturally drive pH levels to increase, strive to achieve a Balanced pH level. If the spa water’s pH level is too low, the following may result: · The sanitizer will dissipate rapidly.
Onzen Technical Guide TERM Parts Per Million (ppm) DEFINITION ppm: parts per million, a standard measure of chemical or mineral concentration. Organic waste Debris such as microorganisms, perspiration, urine, etc. which needs to be burned up or “oxidized” regularly to prevent haze, algae, chloramines, etc. Shock An oxidizer that “burns off ” the organic wastes which cause cloudiness and algae. It is a generic term for a chemical used to oxidize organic wastes. Arctic Pure, REFRESH.

Onzen Technical Guide 1.12.5 Using Sodium Chloride Test Strips The following steps provide guidance to help ensure sodium chloride test strips are used correctly. Steps to Help Ensure Sodium Chloride Test Strips are Used Correctly Step 1. Take Water Sample Take a sample of water from the spa in a small cup (about 25mm / 1” full). NOTE: Always take water samples 25-30cm (12”-18”) below the water surface. Step 2. Place Test Strip in Water Sample Place the lower end of the strip into the water.
Onzen Technical Guide Steps to Help Ensure Sodium Chloride Test Strips are Used Correctly Continued Step 6. Sodium Chloride Adjustment The following levels are ideal: Minimum Maximum 1500 ppm 1800 ppm Note: The Arctic Spas Onzen Salt Chart in this guide provides the estimated impact of adding ½ lb (225 Grams) of salt to your spa. Add or dilute water as needed. · If Sodium Chloride reading is greater than the maximum level, add water. · If Sodium Chloride reading is less than the minimum level, add salt.
Onzen Technical Guide 1.12.6 Program Filtration & Onzen Settings The Onzen Chlorine Production (Onzen Cycle Duration) settings need to be programmed: The following steps provide guidance on how to program the Onzen system settings: Steps to help Set Filtration & Onzen Settings Step 1. Enter Filtration Options Through Topside Controller 5 Press the Filter button (pump 5 on epics) to enter into your filtration options.

Onzen Technical Guide 1.14 Onzen Frequently Asked Questions Onzen Questions Question 1: How do I know if the Onzen system is working? Conduct a “Sanitizer Production test” (Also known as a Smoke test). This procedure activates the Onzen System while de-activating the filtration pump so you can see the mist of gas bubbles produced by the Onzen System.
Onzen Technical Guide Onzen Questions Continued Question 8: What should I do if the spa is not going to be in use or when I go on vacation? (please see FAQ #3) Question 11 Should I use Best Defence or another scale remover? It is recommended that calcium be removed from the water in advance rather than adding a scale remover after the fact. Question 9: What is the impact of phosphates on the Onzen system? High levels of phosphates (above 250 ppb) may reduce the effectiveness of sanitizer output.
24 Monthly Sodium Chloride Filter Water 7.2 – 7.6 ppm Check the Potential Hydrogen to ensure it is in the target range. Check the Sodium Chloride Level to ensure it is in the target range. Refer FCL Maintenance Task Check Calcium Hardness level to ensure it is in the target range. Salt systems perform best with Low Calcium Hardness levels. Adjust the chlorine levels using “Boost” granular chlorine, after heavy use or if the Onzen Output is too low.
*** Important Notice Onzen V8 *** These cells are considered a consumable item and are now designed to be replaced by the customer in order to be more user friendly. We can not express enough to NOT GET THE INTERNAL CONNECTION WET! To change your salt cell remove the set screw on your salt cell with a Phillips screwdriver. Now unthread the salt cell from the housing turning counter clockwise.
