BWT PREMCART Standard filter cartridge

Despite complying with all safety precautions, risks remain especially in case of misuse or inappropriate handling. Each technical device is to be maintained and serviced regularly to function properly. Chemicals, solvents and vapours must not come into contact with the filter system.

Any use contrary to the intended use, e.g., if the filter system is fed with water that is not of drinking water quality, results in a health hazard when the water is drunk: - microbiological hazard due the contaminationwith pathogenic germs; - Hazard from too high a concetration of heavy metal or organic contamination.

To protect the drinking water, maintenance and any other work on the filter system has to be carried out considering national directives for drinking water installations ( e.g. DIN 1988, EN 1717) and applicable state and local regulations. Unauthorised alterations to the filter system and technical modifications are not permitted. The installation location must be protected against freezing and direct sunlight.

If the authorities ot the operator of the water supply system release instructions to boil the potable water due to microbial contamination it is necessary to boil the filtered water before consumption. If the drinking water quality is restored the filter system must be replaced and connections cleaned.

Two type-tested non return valves (in accordance with DIN EN 13959) are included in the filter head. Large kitchen appliances may require a higher level of protection against backflow due to their contamination potential (e.g. cleaning chemicals). If such appliances are connected downstream of the filrer system, the appropriate safety devices must be intagrated into the large kitchen appliance.

Separate the filter system from the water supply prior to maintenance work on the drinking water supply. Rinse the water line before reconnecting the filter system.

Disconnect the power supply of the applicance prior to installation. Chemicals, solvents and vapours must not come into contact with the filter system.

Observe all national directives for drinking water installations (e.g. DIN 1988, EN 1717) and applicable state and local regulations, general sanitary requirements and technical data for the protection of drinking water. Do not install the filter system near heat sources, open fire places or naked flames.

A check (shut-off) valve upstream of the filter system must be installed. If the product has been stored below freezing point (0 °C), leave the unpacked product at the ambient temperature of the installation location for a minimum of 24 hours prior to operation.

Use only connections with gaskets or flat seals. Conical seals damage the filter head connections and will invalidate the warranty claim. The appliance needs to be connected with hoses in accordance with DVGW W 543 or NSF 42/53
