Liner guarantees

SUBJECT AND SCOPE OF THE
GUARANTEE
Leaktightness and durability of
the weld seams. The guarantee is
limited to replacement or repair of
the liner recognised as defective
without any other damages or
interest.
Folds that appear after the liner is fitted are not covered in the scope of this guarantee, these could be the
result of pool water chemical and physical properties that are outside the acceptable ranges (the water
temperature must be below 28°C, the pH must be between 7.0 and 7.4 if the pool is treated with water,
or between 7.4 and 8.0 is the pool is treated with Bromine, and the concentration of disinfectant must be
within the range recommended by the manufacturer of the water treatment products).
Also excluded from the scope of the guarantee is the appearance of yellow stains or discolouration long
the water line. This may be the result of the deposition of organic compounds floating on the surface
of the water (sun creams and oils, residue of hydrocarbon combustion or smoke from wood fires). The
water line should be cleaned regularly using a suitable product (not provided) and non abrasive sponge.
Water with a very high concentration of calcium can also cause this type of staining due to the build up
of limescale on the membrane. Hard water with a TH greater than 250 ppm should be treated with a
product to eliminate limescale and suitable for use in pools (not provided). Your water supplier can provide
information regarding the hardness of your water.
The following are also excluded from the scope of this guarantee:
• stains caused by the growth of algae and micro-organisms: the pool water should be treated regularly
with an appropriate dose of a suitable disinfectant and algaecide ;
• stains, discolouration and wrinkles caused by direct contact with solid oxidising products in direct
contact with the membrane (thrown directly into the pool) or pockets of excessively high concentrations
of oxidising agents (Frequently associated with failure to run filtration during the dissolution phase);
• stains caused by stagnation and/or decomposition of a foreign body in contact with the liner (dead
leaves, oxidisable metallic objects, miscellaneous detritus, etc.);
• damage caused by direct contact with incompatible materials such as bitumen, tar, oils, polystyrene
panels, polyurethane. Never apply adhesive tape or glue to the membrane;
• tears in the liner under the hung liner locking track caused by moving the liner without first releasing
it from the locking track.
