1.14 Arctic Spas Onzen Maintenance Schedule
The following table outlines the typical water maintenance program required for an Arctic Spa fitted with Onzen.
To help ensure chemicals dissolve appropriately it is good practice to first mix/dissolve the chemical in an uncontaminated container of hot water before carefully adding to the spa water.

Maintenance Task
Check the Total Alkalinity to ensure it is in the target range.
Check the Potential Hydrogen to ensure it is in the target range.
Check the Free Chlorine Level to ensure it is in the target range.
Adjust the chlorine levels using “Boost” granular chlorine, after heavy use or if the Onzen Output is too low
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.
Check the Sodium Chloride Level to ensure it is in the target range.
If spa use changes significantly, adjust the output level of Onzen
Chlorine Production ( “On” )

Note: It is also good practice to take a water sample on a regular basis and have the water independently tested by your local spa/pool store.
Low TA – Can be raised by adding Arctic Pure, Perfect Balance to spa water. High TA – Can be lowered by adding Arctic Pure, Adjust Down to spa water.
Salt systems naturally drive pH levels to increase, strive to achieve a Low pH level 7.2. pH must not exceed 7.6.
Low pH – Can be raised by adding Arctic Pure, Adjust Up to the spa water.
High pH – Can be lowered by adding Arctic Pure, Adjust Down to spa water.
Low FCL – Can be raised by adding Arctic Pure, Boost and or turning Onzen Cycle Duration (Chlorine Production On) Level up.
High FCL – Can be lowered by:
• Natural cause over a few days.
• Turning Onzen Cycle Duration (Chlorine Production On) down.
• Adding Arctic Pure, X-it.
The above is dependent on FCL level, spa usage and bather load.
Refer FCL Maintenance Action to Adjust/Correct.
High CH – lower with a stain & scale controller such as Arctic Pure,
Best Defence, to help hold Calcium in suspension.
Once Sodium Chloride reading is in the ideal range salt concentration will only change if water is splashed or drained out. Do not add salt unless this test confirms the level is below the chemical target range.
High Sodium Chloride – add water.
Low Sodium Chloride – add salt.
Go into low level settings and adjust Onzen Cycle Duration (Chlorine Production On) accordingly.
Adjust to suit spa usage and bather load.
Change the filter in accordance with Owners Manual instructions.
Change the water in accordance with Owners Manual instructions.
