TREATING THE WATER
WARNING: The information con-
tained in the following sections about
Water Treatment and Filtering are
generalities. If you acquire any of
these materials, we recommend that
you follow the instructions which
accompany the given product close-
ly.
In order to keep the pool water clean
and clear, you must use a disinfect-
ing agent. Its role is to kill off any
micro-organism and bacteria con-
tained in the water and to prevent
algae growth. Disinfection involves
two main factors: the water’s acidity
(pH) and its chlorin e content.
The pH value indicates whether a
given body of water is acid or alka-
line and to what degree.
The water in a swimming pool must
have a pH value ranging between
7.2 and 7.6. Beyond this level, the
action of chlorine is considerably
inhibited and the water can become
irritating. If the pH value is below 7.2
the water is aggressive and can be
the cause of corrosion of the metal
parts of pool appliances.
CHLORINE CONTENT
This is measured in milligram-liters
(mgl) of active chlorine. This value
must be situated between 0.4 and
1 mgl. The water must be tested for
pH and chlorine values by colori-
metric analysis, using an analysis
kit. We strongly recommend that
you replace the kit’s reagents once
a year. Observe the instructions pro-
vided with the kit.
I - PUTTING THE POOL INTO
SERVICE
When reopening the pool or refilling
it with water, the following operations
should be performed:
1 - pH
Check the pH value, which should
be situated between 7.2 and 7.6.
Use the analysis kit. If the pH value
found is higher than 7.6, use “pH
MOINS” (pH decreaser);
If the pH value found is lower than
7.2, use “pH PLUS” (pH increaser).
Comply with the dosages indicated
on the package.
2- Chlorine
Check the active chlorine value,
which must be at least 0.4mgl.
If the value found is lower than this,
use chlore rapide (rapid action chlo-
rine) in granulated or tablet form in
order to rapidly rebuild the minimum
active chlorine level.
For normal operating, place the
200g or 600g chlore lent (slow action
chlorine) chlorine cakes in the skim-
mer (200g for 25 m3 water). The
slow distribution of this chlorine will
keep the chlorine values of your
pool stable for approximately 8 to 10
days.
WARNING: It is very important that
chlorine products be placed exclu-
sively in the skimmer.
3 - Stabilizing agent
Sun rays and warm water tem-
peratures decompose chlorine,
largely imparing its disinfecting
capacity and leading to increased
chlorine requirements. In order to
eliminate this problem, when filling
the pool, use the stabilisant stabiliz-
ing agent.
This operation need not be renewed
as long as the pool is not drained.
Please see the instructions provided
with the technical description of the
product.
Please note that addition of too
much stabilizing agent will have
a chlorine-inhibiting effect. In this
case, it suffices to eliminate 2 to 3%
of the water in the pool every week,
preferably during cleaning opera-
tions.
4 - Water-softening agent
If using hard water (containing lime),
initial treatment is very important. In
order to prevent lime deposits in the
pool or in the filter, use a water-soft-
ening or anti-liming product, follow-
ing the instructions on the package.
II - MAINTENANCE
When all the above operations have
been successfully performed (pH,
Chlorine, stabilizing agent and anti-
liming agent), it is importante to
ensure proper maintenance:
1- Once a week, control pH
and chlorine levels.
The pH value is generally quite sta-
ble, but it can be modified by adding
water to the pool and by the use of
organic chlorine (e.g. Javel water or
Clorox), which often raises the water
pH level and decomposes rapidly.
2 - Check chlorine level.
If it has dropped below 0.4mgl, use
chlore rapide (rapid action chlorine).
3 - Check
(slow action chlorine; 200g or 600g)
in the skimmer. Do not wait for them
to dissolve entirely before adding the
new ones.
III - ANTI-ALGATE TRETMENT
1- Preventive treatment:
At the dosage prescribed above,
chlorine also acts as an algicide.
Stormy weather, frequent use of the
pool, faulty filtering are factors which
can increase the rate of algae for-
mation, resulting in slippery, slightly
greenish walls. In this case, do not
hesitate to apply a high chlorine dos-
age and leave the filter on around
the clock.
2 - High-dosage algicide:
If in spite of this measure the algae
do not disappear, use a very active
algicide.
IV - FLOCCULATION
Certain very fine organic particles
may not be sufficiently filtered by
sand filter action. The use of a floc-
culating agent will enhance the effi-
ciency of filtering, thus eliminating all
suspended particles in pool water.
Start by putting the flocculating
agent into the filter. If it turns out
that this is insufficient, perform floc-
culation directly in the pool itself.
Observe the instructions on the
package.
V - WINTER CARE
At the end of the season, after a
thorough cleaning operation and
high-dosage chlorine treatment, use
the “HIVERNAGE” (wintering) prod-
uct in the prescribed doses.
