Summary:
•
A swimming pool with a high proportion of chlorine/unbalanced water reduces the lifespan of
the cover and accelerates the decomposition process.
•
By following a few simple rules for maintaining your solar cover, you can ensure that your solar
and swimming pool cover will last longer.
Maintaining the ideal chlorine value:
Remove the solar cover from the pool when chlorinating pool water and before shock disinfection to
prevent chemical damage. Make sure that the water is balanced.
•
The pH value (potentia Hydrogenii) is ideal at a value of 7.4 (tolerance range: 7,2–7,8). If
the pH is too low, the water becomes very corrosive. If the pH is too high, the water becomes
alkaline.
•
The lime hardness (CH) is ideal at a value of 275 ppm (tolerance range: 150–400 ppm). If
the CH value is too low, the water becomes very corrosive. If the CH value is too high, the water
becomes alkaline.
•
The total alkalinity (TA) is ideal at a value of 100 ppm (tolerance range: 80–120 ppm). If the
TA value is too low, the water becomes very corrosive. If the TA value is too high, the water
becomes alkaline.
The proportion of FC (free chlorine) must not be higher than 4.0 ppm (4 parts of chlorine to 1 million
parts of water, corresponds to 4 mℓ per litre). The ideal value is 2.0 ppm, tolerance range between 1.0–
3.0 ppm. The ideal value for CC (combined chlorine) is 0 ppm and should not exceed 0.2 ppm.
If "shock chlorination" is carried out in a swimming pool, make sure that the cover is completely removed
from the surface of the water and only put back on when the chlorine value has returned to normal.
Too high a chlorine value and unbalanced water increase the corrosive effect on the pool cover and
lead to premature aging, bleaching, discoloration and crystallization of the chemical residues on the
surface of the cover.
In its natural state, chlorine is gaseous, if it is added to the water as an additive (solid, liquid or gaseous),
it automatically changes back to its natural state (gaseous), rises in the water and is then evaporated to
the atmosphere. When using a bubble cover, there is no evaporation, and the chlorine circulates in the
water, which is caused by the filter system and pool pump. This is how the water is purified. When the
cover is in place, the chlorine content in the water increases. In order to avoid an increased chlorine
concentration, both the content and the addition must be reduced by 30–60 %. The amount of chlorine
in automatic chlorine dispensers, saltwater chlorine systems and manual addition should be reduced to
the appropriate value in order to maintain the correct chlorine content and water balance.
The pump and filter should be used during the warmest part of the day between 10 a.m. and 4 p.m. with
a solar or energy-absorbing cover placed over the pool. The sun heats the water through the solar cover,
at the same time the cover absorbs heat and transfers it to the water. The warmer water rises with the
chlorine gas, while the water below stays cool. The heat is released and the chlorine circulates again in
the water. The concentrated chlorine mixes in the warm and cold water and cannot attack the cover in
this way. Thus, the solar cover is used optimally and its service life is increased.
When the cover is placed on the pool and there is sunshine, the temperature should not exceed 40 ℃,
as this can reduce the life of the material. Do not expose the cover to direct sunlight when it is not in
use. Overheating the cover can damage the air chambers.
