MAINTENANCE OF THE WATER
• The effects of a very high pH level are:
- The disinfectant is less effective.
- Scale may appear on the acrylic and equipment.
- The water may become cloudy.
- The filter cartridge can become blocked.
Check the pH of the Spa water daily using the pH test set. (not supplied)
If the pH is above the indexes, use pH MINOR SPA. Wait for two hours and re-do the pH test.
If the pH is below indexes, use pH MAJOR SPA. Wait for two hours and re-do the pH test.
When the pH index has been adjusted to the values indicated above, proceed to the next step.
5.4. DISINFECTION OF THE WATER
Disinfection of the water is of utmost importance in order to destroy algae, bacteria and organisms
that could develop in the water. However, excessive disinfection could cause skin and eye irritation.
BROMIDE TABLETS are a suitable disinfectant for the Spa water. This product is placed in the
pre-filter and gradually dissolves.
Check the residual bromide level daily using the Br analyser set.
The recommended level of residual bromide is between 2.2 and 3.3 ppm.
5.5. USE OF SPECIAL PRODUCTS
Apart from products to maintain the pH and disinfectant level, there are other products formulated
especially for use in Spas that will help you to maintain the water and installation in perfect
condition.
• PA-ANTI-CALCAREOUS: This prevents the precipitation of calcium salts (scale),
particularly in hard water. This product should be added weekly and whenever the water
is renewed.
• SPA-ALGAECIDE: This algaecide prevents algae from growing in the Spa water.
This product is added weekly and whenever the water is renewed.
• SPA-ANTIFOAM: Foam is often formed owing to the agitation of the water and grease
present in the water. Whenever there is a significant amount of foam, remove it with Spa-
Antifoam.
• SPA-DEGREASER: To remove rings of dirt and grease that form on the walls of the Spa.
To use this product, it is recommended to empty the Spa and apply a degreaser with a
sponge on the parts to be cleaned. Rinse immediately with plenty of water.
5.6. Ozone Generator (Only for Spas with this feature)
Ozone, O
, is an oxidising chemical component which is very effective in disinfecting water. Its
3
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.
