Water maintenance is one of the areas where the user should provide greatest attention, given its importance. This maintenance will depend on the mineral content of the water used, of the Spa’s frequency of use, and of the number of people using the Spa.
There are three main points to take into account inwater maintenance:
• WATER FILTRATION
• CHEMICAL ANALYSIS AND PH CONTROL
• DISINFECTION OF THE WATER
SAFETY IN USE OF CHEMICAL PRODUCTS
Before using any chemical product, carefully read the instructions for use on its product label.
A pH index of between 7.2 and 7.6 is recommended.
The pH level measures the acidity and alkalinity: Values above 7 are alkali and below 7, are acid.
If the level of pH is very low, the effects are as follows:
⋅ The disinfectant will dissolve rapidly.
⋅ The Spa kit may start to showcorrosion.
⋅ The water may start to produce irritation in bathers.
If the level of pH is very high, the effects are as follows:
⋅ The disinfectant is less effective.
⋅ The acrylic and the kit may start to showscaling.
⋅ The water may turn cloudy.
⋅ The filter cartridge pores may be obstructed.
Check the pH of the water with the pH analyser case on a daily basis.
If the pH is above these indexes, use pH MINOR SPA.Wait for two hours before doing the pH test. When the pH index has been adjusted to the values indicated above, proceed to the next step.
Disinfecting the water is of utmost importance in order to destroy algae, bacteria and any other organisms that may grow in the water. However, excessive disinfection can cause irritations to the skin and eyes.
The appropriate disinfectant for your Spa water is BROMINE TABLETS. Place this product in the pre-filter for it to gradually dissolve.
Check the level of residual bromine using the Br analyser case on a daily basis.
Residual bromine levels of between 2.2 and 3.3 ppm are recommended.
Should you use Chlorine, in order for it to be effective, you must maintain a concentration of Free Residual Chlorine of between 0.5 and 1.5 ppm.
USE OF SPECIAL PRODUCTS
In addition to products for maintaining pH and disinfectant levels, there are others especially designed for use in Spas which will help you to maintain the water and the installations in perfect conditions.
Ozone, O3, is an oxidising chemical component which is very effective in disinfecting water. Its main advantage is that it leaves no chemical residue and is odourless.
Its disinfectant properties are based on its oxidising potential, which leads to the elimination of any organic matter that there may be in the water.
In order to produce ozone, some Spas have an ozonator which, with electricity, can produce ions of ozone from atmospheric oxygen. This process occurs automatically, and the product generated is injected via the filtration return nozzles. Thus, it is not necessary for the user to activate any mechanism for its generation.
The water is collected by the overflow, the drains or the skimmer, due to the suction of the filter pump.
Then it passes through the heat exchanger and in its outlet it is injected with ozone. The water is distributed via the filtration return system.
Ozone treatment does not exclude the use of other chemical products such as Bromine or Chlorine.
The ozone is considered as a complementary process to the ones above, thus reducing the consumption of Bromine or Chlorine.
QUICK GUIDE FOR CHEMICAL PRODUCT APPLICATION
|Reason for use||Amounts per m3|
|Frequency of use|
|PH MINOR SPA||Add if the pH test comes out above recommended values (7.2-7.6 ppm).||Add according to recommendations of the chemical product manufacturer.||Analyse the pH daily with the pH Test.|
PH MAJOR SPA
Add if the pH test is below recommended values
|Add according to recommendations of the chemical product manufacturer.||Analyse the pH daily with the pH Test.|
Add if the Br test is above recommended values
|Add according to recommendations of the chemical product manufacturer.||Analyse the Br daily with the Br. Test.|
LIME SCALE REMOVER
|Avoid the formation of calcium salts (scaling).||Add according to recommendations of the chemical product manufacturer.||Once per week, and each time the water is renewed.|
ALGAECIDE FOR SPAS
Prevents the growth of algae in the water.
|Add according to recommendations of the chemical product manufacturer.||Once per week, and each time the water is renewed.|
Eliminate rings of dirt on the Spa walls.
|Scrub with a sponge and immediately rinse with abundant water.||Whenever dirt is observed on the Spa walls.|
|FOAM REMOVER||Presence of foam in water.||Add according to recommendations of the chemical product manufacturer.|
Whenever foam appear in the water.
