Blow molded Sand Filters are designed to work with water at a temperature than 0ºC (32 ºF) and than 45ºC (113 ºF).The filter should never be operated outside of these temperatures or damage may occur.2. The installation should be carried out in accordance to the safety instructions of swimming pools and thespecific instructions for each facility.3. Prior to installation, read instructions carefully. Installation should only be performed by a qualified pool professional.4. To reduce the risk of injury, do not permit children to play near this product.5. Incorrectly installed equipment may fail, causing severe injury or property damage.6. Chemical spills and fumes can weaken Swimming Pool/ Spa. Corrosion can cause filters and other equipment to fail, resultingin severe injury or property damage. Do not store pool chemicals near your equipment.7. Any modification of the filter requires the prior consent from the supplier’s original replacement parts and accessoriesauthorized by the manufacturer ensure a high level of safety. The supplier assumes no liability for the damage and injuriescaused by unauthorized replacement parts and accessories.8.
