IMPORTANT:
The hydraulic and electrical connections must comply with good professional practice and the
applicable standards for the location of the filter installation. It is especially important to fit effective
air-chamber units if the water inplet and outlet piping is fitted with devices likely to generate water-hammer
effects (for example, solenoid valves).
BWT reserves the right to modify the technical characteristics of its appliances without prior notice.
USE
The BWT PURITY PRO XL filter is a range of backwash and co-current flush filters for clarification, iron removal,
deodourisation, dechlorination and organic or colloidal removal.
FILTER COMPOSITION
Each BWT PURITY PRO XL filter consists of two parts:
•
A body containing the active medium;
•
A hydraulic head enabling the three functions: service, washing and rinsing.
The bodies are 4'' aperture filament roll bottles made of composite material and are available in 4 sizes:
550 mm Ø, 610 mm Ø, 770 mm Ø and 930 mm Ø.
These columns have a high cylindrical shape and are particularly suited to the construction of bilayer clarifying
filters, neutralizers or dechlorinator-deodorisers.
The electronic control unit provides the means to control the filter and the various washing stages. Equipped
with microprocessors, it can be programmed through the 5-key pad on the front panel. It controls solenoid
valves using very low voltage safety current (24 Volts AC). A filter with a filter element is provided to protect
the solenoid valves from impurities in the network. It is crucial that it be operational in the intended
configuration.
Moreover, like any electrical assembly, the control box electronics are sensitive to electrical or magnetic
disturbance. The control unit is fitted with a series of filters to eliminate the most common interference.
However, should the unit be located near to power switches, transformers or any other source of interference,
shielded cable should be used for all connections, and a suitable interference suppressor fitted.
