6.4. Water maintenance

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.

It is advisable that always the same person handles the chemical products. Keep these products away from children.
Add the exact amounts to the water, as specified.
Keep containers tightly closed in dry, well-ventilated places.
Do not inhale chemical products, and take care not to let them come into contact with the eyes,⋅ nose or mouth. Wash hands after use.
Follow the emergency instructions on the product label in the event of an accident or ingestion.
Do not smoke while handling these products – they may be flammable.
Do not store these products inside the Spa unit.
Do not mix products. Add first one and then the other to the water, to avoid possible reactions.
Do not add chemical products to the water if there is someone in the Spa.

PH ADJUSTMENT

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.

ATTENTION
It is very important to maintain the correct pH level both for the disinfectant to work properly and to prevent corrosion or deposits on the Spa. Any damage caused by an inadequate pH level is not covered by your Spa guarantee.

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.

WATER DESINFECTION

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.

TIMESCALE REMOVER FOR SPAS: Avoids the formation of calcium salts (scaling), especially in hard water. This product is added weekly and every time the water is renewed.
ALGAECIDE FOR SPAS: This algaecide prevents the growth of algae in the Spa water. The product is added weekly and every time the water is renewed.
FOAM REMOVER FOR SPAS: Due to the agitation of the water and the grease present in it, foam often forms in Spas. When ever you notice a significant amount of foam in the water, you can eliminate it with this product.
⋅GREASE REMOVER FOR SPAS: For eliminating the rings of dirt and grease that form on the walls of the Spa. To use this product we advise emptying the water from the Spa, and applying the grease remover with a sponge on the areas to be cleaned. Then rinse immediately with abundantwater.

OZONE GENERATOR

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
