Maintenance Programme Of The Spa Water; Ph Adjustment; Disinfection Of Water; Use Of Special Products - Astralpool SPA 4DREAM: 34394 Manuel De Fonctionnement

UTILIZATION MANUAL
Do not mix products. Add first one and then the
other to the water, to avoid possible reactions
among them.
Do not add chemical products to the water if there
is someone in the Spa.
7.2. MAINTENANCE PROGRAMME OF THE SPA
WATER
(SPA MAINTENANCE KIT, not included)
All chemical products: Bromine in tablets, Algaecides,
Anti-calcareous and pH reducer, must be added in the
pre-filter basket, with the jet pump on for at least ten
minutes.
USE OF THE ANALYSER CASE Br Ph
Ph Test
Fill the right phial with water from the Spa
Add 5 drops of SOLUCION2 (PHENOL RED). Cover and
shake.
Compare the colour obtained with the colour scale.
The ideal level is between 7.2 and 7.6.
BROMIDE test
To determine the total residual bromide level of the
Spa water.
Fill the left phial with water from the Spa
Add 5 drops of SOLUCION1 (OTO). Cover and shake.
Compare the colour obtained with the colour scale.
The corresponding colour equals the ppm (ppm=g/
3
m ) of the total residual bromide.
The ideal level is between 2.2 and 3.3 ppm.

7.3. pH ADJUSTMENT

A pH index between 7.2 and 7.6 is recommended.
The pH level measures the acidity and alkalinity.
Values above 7 are alkali and below 7 acid.
It is very important to maintain the correct
pH level both for the disinfectant to work
properly and to
deposits on the Spa.
prevent corrosion
The effects of a very low pH level are:
The disinfectant quickly dissipates.
The Spa equipment could corrode.
The water may cause irritation to bathers.
The effects of a very high pH level are:
The disinfectant is less effective.
Deposits will appear on the shell surface and
equipment.
The water may become cloudy.
The pores of the filtering cartridge may
become blocked.
Check the pH of the water daily using the pH analyser
case.
If the pH is above the indexes, use pH MINOR SPA.
Wait two hours and re-do the pH test.
Once the pH index has been adjusted to the values
indicated above, proceed with the following point.
7.4. DISINFECTION OF THE WATER
Disinfection of water is of utmost importance in order
to destroy algae, bacteria and organisms that could
develop in the water. However, excessive disinfection
could cause irritations to the skin and eyes.
BROMIDE IN TABLETS is a suitable disinfectant for the
water of the Spa. This product is places in the floating
dosifier (not included) and it dissolves gradually.
Check the residual bromide level daily using the Br
analyser case.
The recommended level of residual bromide is
between 2.2 and 3.3 ppm.
The chemical product must not be added
through the filter as this could damage the
materials and would limit its efficiency.
Always use a pre-filer basket.

7.5. USE OF SPECIAL PRODUCTS

Apart from products to maintain the pH and
disinfectant level, there are other products specially
created to be used in Spas that will help you
or
maintaining the water and installation in perfect
condition.
