PUROTAP mini
The PUROTAP cartridge filters lime and aggressive substances such as sulphates, nitrates and chlorides out of
the fill water. The appliance uses a mixed bed ion exchanger to provide demineralised, fully desalinated water.
This method does not emit any chemical additives into the water. The appliance operates without an external
power connection.
Function
The table opposite shows the capacity
of the full desalination cartridge as a
function of the total hardness of the fill
water.
Example: At a hardness of 20°fH/11°dH,
PUROTAP 1000 delivers approximately
750 l fully desalinated water.

Safety instructions
In the DIN EN 1717 (Germany) field of application, a pipe disconnector must be installed for fill-up.
The cartridge does not contain mechanisms for automatic stop. The work with the cartridge may only take place
under constant monitoring. The cartridge may only be under pressure during the duration of the fill-up. Temp.
max. 60 °C, pressure
max. 4 bar
.
The cartridge must only be subject to pressure during the short period of use.
For permanent connection we recommend PUROTAP compenso.
Flush the cartridge with approx. 10 l of water before each use. Flush for longer in the case of algae growth.
The cartridge must not be allowed to dry out.
The ion exchange resin in the cartridge must not enter the heating system. As a precaution, a fine filter is fitted
which must not be removed.
After use, always close the freshwater tap, the shut-off valve on the PUROTAP and the boiler fill valve.
As a point of safety, remove the hoses after filling.
The entire cartridge is made from PE and can be disposed of as household waste.
