2. TAKING CARE OF THE STRUCTURE OF THE POOL
- The wood
Wood is a living substance which is subject to variations in humidity and temperature. Over the course of time wood is liable to swell, tiny cracks or splits
may appear. Such occurrences do not in any way alter the wood’s resistance or the durability of our materials.
Furthermore, a deformity in the sides of the pool caused by the pressure of the water may occur, mainly on the central and lower planks (under maximum
water pressure) – this is normal.
On the understanding that the pool has been assembled according to the instructions provided, there is no cause for concern here regarding the stability
of the structure.
The sterilising high pressure steam treatment of all the timber parts protects the wood from being attacked by insects and fungi. This treatment gives the
timber a greenish hue which does not pose any danger to humans. At any rate, this colour will fade with time. According to how much it is exposed to
direct sunlight, the wood will gradually take on a silvery grey appearance. This process can be slowed down by using a glaze or protective oil, which
ideally should be applied a few weeks after the swimming pool has been installed (this will stabilise the structure and reduce the greenish tinge caused by
the steam treatment…).
- The liner
The liner is a flexible PVC membrane and is exceptionally fragile. Therefore make sure that the water in the swimming pool is absolutely clean and that the
pH level is not too high.
- The surface of the water is the most exposed to a variety of deposits so it must be cleaned regularly with the appropriate products ( no solvents and no
abrasives should be used).
- Never put any undiluted treatment product directly on to the liner as this may cause discoloration. The solid blocks of these products must be dissolved in
a chlorine diffuser or ion the skimmer basket.
- When you pause the filtration system, particularly in winter, it is essential to treat the pool to prevent the build up of moss and calcium.
i
Never completely drain the pool. You must never allow the liner to be left for more than 24 hours without
water in the pool otherwise it may change shape, cracks may appear, etc.
Stains on the liner: causes and solutions
COLORS OF
THE SPOTS
POSSIBLE CAUSES WHAT SHOULD YOU DO
White
1. Discoloration of the material due to contact
with a chemical (chlorine…)
1. No solution
White /grey 1. Calcium deposits
1. Drain the pool, have it cleaned by machine, refill the basin, get the water balance right and put in an
anti-calcium treatment.
Pink
1. Migration of bacteria which have developed
underneath the membrane as a result of an
underlying humidity
1) Lower the pH level and the temperature of the water. Carry out a high- power cleaning treatment and
run the filter for 48 hours non-stop. To prevent this recurring keep the pH level between 7 and 7.4
Green
1. Algae
2.accelerated deterioration of the surface of the
water due to sun and oxidising products
1.Correct the pH level, Carry out a high- power cleaning treatment and run the filter for 48 hours non-
stop, have the pool cleaned by machine.
2. Use a descaler, brush the stains then vacuum the deposits.
Orange/brown
1. Dead algae
2. Water contains iron oxide or copper
1. Brush the sides of the pool and vacuum the deposits.
2. Lower the pH level and the temperature of the water, brush the stains then vacuum the deposits.
Black
1. Migration of bacteria which have developed
underneath the membrane as a result of an
underlying humidity 2. Water contains heavy
metals (iron, silver …)
1.Lower the pH level and the temperature of the water. Carry out a high- power cleaning treatment and
run the filter for 48 hours non-stop. To prevent this recurring keep the pH level between 6.8 and 7.0
2. Lower the pH level and the temperature of the water, brush the stains then vacuum the deposits
Liner is sticky

deposits
1. Algae
2. Water contains heavy metals (iron, silver …)
1.Correct the pH level, Carry out a high- power cleaning treatment and run the filter for 48 hours
non-stop, have the pool cleaned by machine.
2. . Lower the pH level and the temperature of the water, brush the stains then vacuum the deposits
3. WINTER CARE AND SAFETY
Winter care is an essential element of maintaining the pool. The aim of this operation is to avoid the build up of too many algae and calcium deposits
inside the basin during the winter. By adding a winter care product you will be protecting the water and your pool in winter, thus making it easier to clean
at the start of the new season.
i It is imperative that you do not completely drain the pool in the winter (or for a long period of time). In fact totally
draining the pool does not improve the condition either of the liner or of the structure of the basin, since the water
plays a dual role, providing thermal insulation and ballast. The pool is better protected from weather hasards, the
water pressure prevents anything going through the sides of the pool (in case of ground movement) and offsets the
pressure of soil and groundwater.
Details about winter care of the filter are given in the notes provided with the tank.
It is a good idea to remove the ladder and put it away in a safe place. For safety reasons, this ladder must only be used for accessing the pool. You should
cover the swimming pool with a winter canvas cover or better still a tarpaulin safety cover certified according to safety standard NF P 90 308. In this case
you will have to remove any snow from the cover regularly. But having a cover over the pool does not mean that you do not need to be vigilant. You will
have to check the state of the water regularly and if the water is turning green you will have to treat it using a chlorine solution.
Finally, make sure that rainwater can drain away properly around the pool.
4. DISMANTLING THE POOL
Whilst it is possible to do so, dismantling the pool is not recommended. In fact, it may cause damage to the component parts and repositioning the liner
when reassembling the pool is a very delicate operation.
