TERM DEFINITION
Onzen An all-natural, salt-water soening and maintenance system.
Onzen Output Electrode Platinum-iridium Titanium electrode - equipped salt cell converts the saltwater
solution to sanitizer, and as this solution reverts back to its natural form (salt) aer
sanitizing. Unless large volumes of water are added to the spa you never have to add
more salt.
Onzen Output Electrode Version Modication status of the electrode ed to the spa.
Calcium Hardness (CH) Calcium Hardness is a measure of the total amount of dissolved calcium salts in the
water.
CH helps determine how scaling or corrosive the water is. It is believed that
calcium helps control the corrosive nature of water.
Calcium has two major problems in Hot Water Chemistry:
1. CH has a tendency to precipitate (fall out of suspension in high
temperatures.
2. High pH will cause calcium to precipitate. e problem with
calcium falling out of suspension is that it collects on the heater
and pump, and shortens their life. Any natural corrosiveness
in the water can be combated by maintaining a slightly higher
Total Alkalinity Level.
Alkalinity Total Alkalinity (TA) A measure of how stable the pH is (a measure of the total levels of carbonates,
bicarbonates, hydroxides, and other alkaline substances in the water).
TA is referred to as the water’s “”pH buer””. In other words, it’s a measure of the
ability of the water to resist changes in pH level.
If the TA is too low, the pH level will uctuate widely from high to low.
Fluctuations in pH can cause corrosion or scaling of the spa components.
Low TA can be corrected by adding Arctic Pure, Perfect Balance to the spa water.
If the Total Alkalinity is too high, the water will be more susceptible to scale and
high pH. High pH may be dicult to bring down. Note: Salt systems naturally
drive pH levels to increase.
High TA can be lowered by adding Arctic Pure, Adjust Down to the spa water.
Once the TA is Balanced, it normally remains stable, although some sanitizers, and
the addition of more water with a high or low alkalinity will raise or lower the TA
reading of the water.

Onzen Technical Guide
TERM DEFINITION
Potential Hydrogen
(pH)
e pH level is the measure of alkalinity.
Maintaining a Balanced pH level is extremely important for:
· Optimizing the eectiveness 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:
· e sanitizer will dissipate rapidly.
· e water may become irritation to spa users.
· e spa’s equipment may corrode.
Low pH can be raised by adding Arctic Pure, Adjust Up to the spa water.
If the pH level is too high, the following may result:
· e sanitizer is less eective.
· Scale will form on the spa shell surface and the equipment.
· High pH will cause calcium to precipitate (fall out of suspension).
· e water may become cloudy.
High pH can be lowered by adding Arctic Pure, Adjust Down to the spa water.
It is important to check the pH on a regular basis. e pH will be aected by the
bather load, the addition of new water, the addition of various chemicals, and the
type of sanitizer used.
Chlorine
Free Chlorine (FCL)
FCL is the active form of chlorine that actually kills bacteria and algae (It is a
Sanitizer).
Sanitizer is extremely important for killing algae, bacteria and viruses, and
preventing unwanted organisms for growing in the spa. At the same time, you don’t
want too high a sanitizer level, or it can irritate your skin, lungs and eyes.
Always maintain the sanitizer level in your spa at the recommended level for each
type of sanitizer.
Chlorine Residual e actual level of chlorine in the water aer the chlorine demand has been satised.
Sanitizer Chemical used to kill bacteria.
Generic names: Chlorine, Bromine.
Arctic Pure, Boost or Refresh.

2013 Factory installed Onzen systems serial #150000 and greater will have a two-year warranty on labor and
components. Excluding the electrode that will have a 30-day warranty against defects in workmanship. e electrode as
a consumable part that needs to periodically changed like a lter. Retrot Onzen systems will have the same warranty
minus labor.
We will continue to support old versions of onzen as we have in the past. Spas with serial #149999 and lower will have a
two-year warranty on labor and components. e electrode will have a 1-year warranty. Retrot Onzen systems will have
the same warranty minus labor. We may require an email address for the consumer in order to process claims so we can
send them clear denition of how to use their system and clearly tell them that the electrodes are consumable items like
lters or chlorine etc).
e recommended salt concentration is 1500-1800 ppm. Even though the lifespan on the electrode seems to be
maximized at 2200-2400 ppm when we consider the overall impact of the corrosive nature of salt on the other spa
components it is clear that lower salt is beer.

dissolve appropriately it is good practice to rst mix/dissolve the chemical in an uncontaminated container of hot water
before carefully adding to the spa water.
Steps to Fill Spa With Water Power Up Spa and Set Water Temperature
Step 1. Fill Spa Fill your spa through the lter intake as shown
to the appropriate level (just under the head rests). If you have
sediment or high mineral content a “carbon lled pre-lter”, as
pictured, can help. (is is optional and will prolong the ll time).
Step 2. Connect/Turn on Electrical Power to the spa once the spa
is lled to the proper level, and turn the power on to the spa on.
Step 3. Set Water Temperature Set the water temperature control
on the Topside Controller to the desired temperature (between
100ºF and 104ºF or 38°C and 40°C).

1.12.3 Establishing Correct Water Chemistry
e following steps provide guidance to help establish correct chemically balanced water.
To help ensure chemicals dissolve appropriately it is good practice to rst mix/dissolve the chemical in an
uncontaminated container of hot water before carefully adding to the spa water.
Steps to Establish Chemically Balanced Water With Onzen
Step 1. Test and Adjust Calcium / Total Alkalinity
(a) Test Calcium hardness. Level should be between 50-150 ppm.
If high, lower with a stain & scale controller such as Arctic Pure,
Best Defence, to help hold the Calcium in suspension.
NOTE: Salt systems perform best with Low Calcium levels.
(b) Test Total Alkalinity. It should be 80 – 100 ppm (100 max). If
high, lower Total Alkalinity with Arctic Pure, Adjust Down (pH
Down) or muriatic acid. Do not raise Total Alkalinity!
WARNING: Skipping these steps on Start-up can cause scaling
problems and cloudy water that may not be covered under warranty.
NOTE: Use all products according to directions on the bole.
Step 2. Test and Adjust pH
Test pH. Levels should be between 7.2 – 7.6.
If pH is high, (over 7.6) add Arctic Pure, Adjust Down.
If pH is low, (under 7.2) add Arctic Pure, Adjust Up.
NOTE: Use all products according to directions on the bole.
NOTE: Salt systems naturally drive pH levels to increase, strive to
achieve a Balanced pH level.
NOTE: High pH will cause calcium to precipitate (fall out of
suspension). e problem with calcium falling out of
suspension is that it collects on the heater and pump, and
shortens their life.
Step 3. Mix Salt Crystals
Dissolve 1/3 of the minimum recommended salt dosage in a 5 Gallon (20
litre) pail of hot water.
Refer Arctic Spas – Onzen Salt Dosage Chart contained in this guide.

Onzen Technical Guide
Steps to Establish Chemically Balanced Water With Onzen Continued
Step 4. Add Salt to Spa Water & Test TA / pH
(a) Slowly pour the dissolved salt from the pail into the spa water.
(b) Run pumps for 5 minutes to help mix salt blend through.
(c) Wait 1 hour.
(d) en test and adjust Total Alkalinity level accordingly.
(e) en test and adjust pH level accordingly.
Refer to steps 3 and 4 for correct TA/pH levels.
Step 5. Repeat Step 3 & 4
Repeat steps 5 and 6, ensuring all sub steps are carried out accordingly.
Step 6. Repeat Step 3 & 4
Repeat steps 5 and 6, ensuring all sub steps are carried out accordingly.
Step 7. Test Sodium Chloride Level
You will now need to test sodium chloride levels.
Refer ‘Using Sodium Chloride Test Strips’ for details.
If sodium chloride levels are low, dissolve 1/2 lb (225 Grams) of salt
(using cup provided) into hot water. Pour the dissolved salt into the
spa water. Test sodium chloride level.
Repeat until required sodium chloride level is reached:
Minimum Maximum
1500 ppm 1800 ppm
Note: e Arctic Spas Onzen Salt Chart in this guide provides the
estimated impact of adding ½ lb (225 Grams) of salt to
your spa.
Note: For start up 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 accommodate 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.

Onzen Technical Guide
1.12.4 Arctic Spas Onzen Salt Dose Guidance Table
e following table identies the salt quantity required for each Arctic spa model and estimated impact of adding half pound (225g) of salt.
For start up 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 accommodate 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.

1.12.5 Using Sodium Chloride Test Strips
e 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.
IMPORTANT Keep top half of strip COMPLETELY dry to get
an accurate reading.
Step 3. Test Duration Period
Leave strip in water for 3 – 5 minutes until yellow band
at top of strip turns dark.
Step 4. Obtain Readings
Obtain your reading: where top of white peak falls on
the number scale.
Read top of peak to the nearest 0.2 division.
Step 5. Correspond Test Result Reading
Correspond the test result reading number with the
numbers on the bole.

Step 6. Sodium Chloride Adjustment
e following levels are ideal:
Minimum Maximum
1500 ppm 1800 ppm
Note: e 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.
Note: Once Sodium Chloride reading is in the ideal range salt
concentration will only change if water is splashed or drained out
and spa is replenished with water. Do not add salt unless this test
conrms the level is below the ideal range.
Warranty: Use of salt other than Arctic Pure sea salt blend will
damage the components and void the warranty. e Arctic Pure
blend has been developed to protect Onzen components from
damage and the use of alternative salt blends will be easily detected
by technicians.
Steps to Stabilize Water
Step 1. Stabilize Spa Water
Once Filtration cycles and ltration duration low level seings have
been programmed place the insulated cover on the spa and allow the
water temperature to stabilize (approximately 16 hours). Make sure
you secure the cover in place using the cover locks. Periodically check
the spa water temperature. When the water temperature climbs above
85°F, (29°C) proceed to the next step.
Note: As heat impacts both Calcium and Total Alkalinity a lile it
is best to heat the water above 29°C (85°F) before advancing to
Establishing Correct Water Chemistry.
Filter Cycle Suspension
During a Filter cycle, if an accessory (a pump, the blower, or the light) is used manually, the Filter cycle is suspended
during the time that the accessories are used.
Once all accessories are turned o (whether manually or by built-in timer), the Filtration cycle remains suspended for
an extra 40 minutes. When a Filtration cycle is suspended the Filtration cycle icon will blink.
