1.13 Arctic Spas Onzen Maintenance Schedule
*** 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. DO 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. This will require you to use your muscles as the cell is threaded in quite tight to prevent any water from getting on to the 12 volt connection. Before threading in the new cell put a generous amount of dielectric grease in and around the 12 volt connections in the centre of the housing and on the end of the cell. Now thread the new cell into the housing. There is a notch built into the threads that will stop the cell precisely where the set screw needs to be installed. If the cell is changed under water the connection will get wet and corrode. The corrosion will destroy the connection between the salt cell and the salt cell housing. This corrosion will be visibly noticeable upon inspection. Warranty will be void If corrosion between the salt cell and salt cell housing is detected.
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.
|Item||Frequency||Maintenance Task||Target Range|
|TA||Weekly||Check the Total Alkalinity to ensure it is in the target range.||80 – 100 ppm|
|pH||Weekly||Check the Potential Hydrogen to ensure it is in the target range.||7.2 – 7.6 ppm|
Weekly (& before
|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||1 – 3 ppm|
|CH||Monthly||Check Calcium Hardness level to ensure it is in the target range. Salt systems perform best with Low Calcium Hardness levels.||50-150 ppm|
|Monthly||Check the Sodium Chloride Level to ensure it is in the target range.||Version 8 2000-2500 ppm|
|As required||If spa use changes significantly, adjust the output level of Onzen Chlorine Production (“On”)||2 – 4 Hours per day suggested|
|Filter||Every 3 Months||Change the filter||N/A|
|Water||Every 6 Months||Change the water||N/A|
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 Salt Water Balance 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 Salt Water Balance 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.
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.
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.
