Maintenance Action to Adjust/Correct
pH Weekly Check the Potential Hydrogen (pH) to ensure it is in the
target range.
Always first check to ensure the pH is within the target
range. If the pH is out of the target range pH must be
adjusted before making any adjustments to chlorine levels
7.2 – 7.6 pH As Salt systems naturally drive pH levels upwards, it is most critical to the performance/life of the salt system to maintain the
pH within the target range.
High pH reduces the effectiveness of chlorine.
• pH level of 7.2 makes chlorine 62% effective (38% loss of effectiveness).
• pH level of 7.5 makes chlorine 50% effective (50% loss of effectiveness).
• pH level of 8 makes chlorine 21% effective (79% loss of effectiveness).
Therefore, high pH causes your Spa Boy system to produce more chlorine thus increasing pH even higher and reducing the
effectiveness of chlorine even further.
Strive to achieve a Low pH level 7.2. pH must not exceed 7.6. If pH is slightly below 7.0ppm do not adjust.
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.
ORP Weekly
(& before
each use)
Check the Free Chlorine Level to ensure it is in the
target range.
545–550 mV /ORP
Using a Drop Test Kit,
0.5ppm Chlorine reading
= approximately 550mV
545-550 mV is the Optimum Range factory default setting.
The user may adjust higher if preferred by contacting their dealer to have it adjusted. Spa Boy will strive to maintain ORP
within the Optimum Range.
Depending on the water chemistry which will be affected by bather load and spa usage, at times the ORP
value will overshoot or undershoot the Optimum Range.
Sodium
Chloride
Monthly Check the Sodium Chloride Level to ensure it is in the
target range.
Version 1 R1 2000 –
25000 ppm
Once Sodium Chloride reading is in the target 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 acceptable range.
High Sodium Chloride - add water above 2500ppm
Low Sodium Chloride - add salt below 2000ppm
Shock Weekly Shock the spas water with Arctic Pure, Refresh N/A At a minimum 1 capful per week should be added for a spa and 2 caps full for an AWP. This amount can be reduced if your
spa is equipment with an Arctic Spas OZONE System.
Filter 3 Monthly Change the filter(s) N/A Change the filter(s) in accordance with Owners Manual instructions. (Pg.19)
Water 6 Monthly Change the water N/A Change the water in accordance with Owners Manual instructions. (Pg.22)
