The user must pay particular attention to the maintenance of water. Maintenance will depend on the mineral content of the water used, how often the Spa is used and how many people use the Spa.64
If the temperature sensors detect a drop in temperature to below 6.7ºC, the heating element and filter pump will connect automatically to prevent the water from freezing and the damage this could cause the Spa.
The equipment will remain connected for 4 minutes after the temperature reaches 7.2ºC.
In colder climates, an additional temperature sensor can be added as a precaution and to avoid freezing conditions not detected by the standard sensor.
If the pump turns off in this situation, empty the Spa and contact your authorised dealer or Technical Assistance Service.
SAFETY IN THE USE OF CHEMICAL PRODUCTS
Before using a chemical product, read the instructions on the product label carefully.
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.
MAINTENANCE SCHEDULE OF THE SPA WATER
All chemical products: Bromine in tablet form, Algaecides, Anti-calcareous and pH reducer, must be added to a floating dispenser (not supplied), with the massage pump on for at least ten minutes.
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.
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.
The effects of a very low pH level are:
– The disinfectant will quickly dissipate.
– The equipment of the Spa become rusty.
– The water can start causing skin irritations to bathers.
• 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.
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.
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.
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.
