USE AND MAINTENANCE OF TIMBER SWIMMING POOLS

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 first 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 filter running during the day, as it is bathing that causes most of the pollution. Regulate the timing of the filter according to

the temperature of the water. The higher the temperature of the water, the more easily bacteria will grow.

Water Temperature

< 10°

10-12°

12-16°

16-24°

24-27°

27-30°

Filtration time

10-12h

-> 20h

Generally speaking, whatever type of system you have, any impurities should be removed if the pool is cleaned regularly using the filter.

The sand filter

: When the amount of impurities in the sand increases, the circulation of the water becomes less efficient and consequently the pressure

increases. Refer to the notes on maintaining the filtration 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 efficiently, 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 fishing 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 filtration level.

Annual treatment: In order to have clean water all the time, clean the filter, change about ⅓ to ½ of the water in the pool and look after it properly through
the winter. Change all the water in your pool every 3 to 4 years.

Problems and solutions :

PROBLEMS

CAUSES

SOLUTIONS

1. Water clear with greenish or

brownish tint.

Large number of brown stains

on the sides of the pool.

Oxidation of metallic salts (iron or copper) present

in the water used to fill the pool

Check the pH level. Put in a calcium and metal

stabiliser when you fill the pool. Clean out the filter.
