6. GUARANTEE
As of the initial date of invoice* issued by PROCOPI BWT GROUPE to the client company,
1. The shell is guaranteed for 10 years against any leaks caused by porosity, failure, or cracking of
the material and not attributable to an impact, use at any pressure other than that stipulated in the
installation instructions, erosion of the inner surface caused by impacting of the sand or inverted water
circulation, freezing of the water in the shell, etc.
2.
The parts of the filter that may be dismantled and removed (laterals, lid, base, multi-port valve,
throughwall bulkhead flanges and their seals, RTM filter neck-O-ring, RTM filter check valve, etc.) are
covered by a 2 year guarantee against defects and damage that is not attributable to abnormal use.**
The aforementioned defective parts shall be replaced, and unless otherwise agreed with PROCOPI BWT
GROUPE, the guarantee covering removable parts will under no circumstances result in the exchange of
a complete filter.
* The changing of an item of equipment or part manufactured or distributed by PROCOPI BWT GROUPE
shall under no circumstances modify the expiration date of the guarantee covering said item of equipment
or part and that is calculated based on the initial date of invoice.
** Examples of abnormal use:
• Corrosion of materials (seals, etc.) in contact with water attributable to the presence of an oxidant
(chlorine, bromine) at a concentration higher than that recommended for pool use.
• Failure to respect the recommended sand granulometry.
• Stress-cracking of ABS parts due to the use of lubricants containing surfactants on their threading or
connections.
• Pressure higher than the maximum operating pressure.
• Circulation of water in the opposite direction to that recommended due to incorrect connection of pipes
to the multi-port valve.
• Sand media cemented by limescale leading to the creation of several preferential paths through the filter
media.
• Installation above the water line without a check valve.
