USE AND MAINTENANCE OF TIMBER SWIMMING POOLS
i
Failure to comply with the maintenance instructions may lead to serious risks to
health, particularly where children are concerned.
1. TREATING THE WATER
Your swimming pool installation is complete! Before you get into the pool for the irst time, it is essential to "prepare" the water. Bathing often leads to
a good deal of pollution caused by things like vegetation, earth, dust, sweat, saliva, hair, grease, etc. The swimming pool water must be protected from
these substances in order to avoid various micro-organisms developing.
In order to do this, a few simple rules may be applied:
- It is a good idea to have the ilter running during the day, as it is bathing that causes most of the pollution. Regulate the timing of the ilter according to
the temperature of the water. The higher the temperature of the water, the more easily bacteria will grow.
Water Temperature
Filtration time
Generally speaking, whatever type of system you have, any impurities should be removed if the pool is cleaned regularly using the ilter.
The sand ilter: When the amount of impurities in the sand increases, the circulation of the water becomes less eficient and consequently the pressure
increases. Refer to the notes on maintaining the iltration unit for cleaning it.
- Analyse the water in your swimming pool: it is a worth checking the pH level (degree of acidity or alkalinity of the water) every week. It should always
range between 7.2 and 7.6. An incorrect pH level may result in the water treatment products working less eficiently, may accelerate the development of
chloramines (causing unpleasant odours and irritation of the mucous membranes...) and the corrosion of any metal parts..
- Treat the water regularly: a weekly disinfectant treatment (bromine, chlorine and active oxygen...) against bacteria will avoid all the problems caused by
poor quality water. One treatment every fortnight with an algaecide effectively combats the initial appearance and further development of algae.

Using and storing chlorinated products
Remember that these are dangerous products that must be stored
and used only as directed by the manufacturers. Do not mix chemical
products with each other. Store products in tightly closed containers
in a cool and well ventilated place; do not expose to direct sunlight.
If using a container for measuring out chemicals, rinse thoroughly
after each use. Read the safety information and instructions provided on
each label carefully. Keep all chemicals out of reach of children..
- Everyday remove as much dirty matter from the pool as possible with a ishing net (fallen leaves, dead insects...) and clean the surface of the water
regularly to remove greasy deposits.
- Empty the pump container. Just like the skimmer container, it is a good idea to empty it regularly to maintain the optimum iltration level.
Annual treatment: In order to have clean water all the time, clean the ilter, change about
the winter. Change all the water in your pool every 3 to 4 years.
