Restarting your spa during the cold season
If you wish to restart your spa after it has remained empty under freezing conditions, remember that the water remaining in
some sections of the piping may still be frozen. This will block the circulation of the water and prevent the normal operation
of the spa and could damage its equipment. We advise you to consult your dealer before trying to restart your spa under
these conditions.
5.9
Preservation of the quality of the water
The preservation of the quality of the water within recommended limits will contribute to your comfort and prolong the life
of the spa equipment. This is a simple task but one that requires regular attention because the chemistry of the water to be
complied with depends on several factors to be balanced. There is no magic formula and this task cannot be avoided. A
nonchalant attitude to the maintenance of the water will lead to a poor condition of the water which could become
unsuitable for bathing and even damage your spa. In order to obtain specific advice about the preservation of the quality of
the water, consult you dealer who will be able to recommend the appropriate chemicals required for the maintenance and
health of your spa water.
CAUTION:
Never store the spa chemicals inside the surrounds of the spa.
5.10
Checking of the pH of the water
The pH is a measurement of the relative acidity or alkalinity of the water and is measured on a scale of 0 to 14. The median
value is 7 and is defined as neutral.
The highest values are alkaline and the lowest values are acid.
It is important to maintain the pH of the spa water between 7.2 and 7.4 in order to achieve effective sterilisation and prevent
irritation to the skin of the users.
Do a pH analysis regularly then raise it or lower it accordingly. Adjust by only adding small quantities of chemicals in order
not to go too far in the other direction.
IT IS VERY IMPORTANT TO MAINTAIN THE WATER OF THE SPA IN A SLIGHTLY ALKALINE CONDITION BETWEEN 7.2 AND 7.4 IN
ORDER TO ACHIEVE EFFECTIVE STERILISATION AND PREVENT IRITATION TO THE SKIN OF USERS.
The further the pH moves away from this range, the more serious the problems will become (proportionally). A low pH will
be corrosive for the metal of the spa equipment.
A high pH will cause the depositing of minerals on the inside walls of the spa (scaling). Furthermore, the ability of the
chemicals to keep the spa clean is affected by pHs outside the recommended range. This is the reason why in addition to
chemicals most of the maintenance kits for spas contain an instrument for measuring the pH of the water.
5.11
Purification of the water
In order to destroy the bacteria and the organic compounds in the spa water, the addition of chemicals must be regularly
repeated.
We recommend you use chemicals with an active oxygen base. Several other additives are also available for your spa. Some
are necessary to compensate for the imbalance of the chemical proportions and others are treatments of a cosmetic nature
or for changing the sensation or the smell produced by the water.
CAUTION:
Do not use (trichloro) chlorine tablets in your spa. This chemical may have an extremely corrosive effect on some
materials used in your spa. Any damage caused by the use of this chemical or by the improper use of other products are not
covered by the warranty of the spa.
5.12
Discharge ozonisation system
As our spas are fitted with a water purification system using ozone extracted from the air, the spa water will require much
less chemicals in order to remain healthy and clear and the intervals between the water draining required will be longer.
The discharge ozonator operates jointly with the circulating pump.
Ozone is a powerful oxidant and disinfectant which will assist the sterilisation of the water and enable a reduction in the
quantity and the cost of the sterilising products. The ozonator starts up automatically during the periods of filtration of the
spa. The reaction time for the ozone is approximately 1/10th of a second and the treatment of the water is therefore done in
the piping and the ozone no longer has any effect when it is discharged through the nozzle. The maintaining of a
satisfactory pH and an adequate level of steriliser is essential. The ozone assists the chemical treatments but is not a
substitute for them. Replace the ozonator after 3 to 4 years depending upon the level of use. Bubbles would continue to be
released through the ozone return nozzle, but would no longer have any effect if the ozonator were not replaced.
