TECHNICAL DATA
The following applies for all the models of the device:
/ The water to be filtered must conform to the European Drinking Water Regulations!
/ Nominal flow rate after backwashing at a pressure loss of 0.2/0.5 bar as given in the table below.
/ The nominal pressure denotes the pressure class, according to which the filter must fulfill the require-
ments of the standards DIN EN 13443-1 and DIN 19628. The maximum operating pressure is lower,
in order to ensure the optimum function of the backwashing filter.

ACCESSORIES
/ Clear 2.0 Automatic controls retrofit kit. For subsequent upgrade of the manual backwashing filter
to an automatic backwashing filter.
/ Clear 2.0 SAFE. Central water monitoring system for installation between built-in rotary flange and
backwashing filter. For monitoring the water consumption and shutting off the water pipe when ad-
justable limits are exceeded. Protects against the effects of water pipe bursts, leakages, defects on the
domestic water installation and unusually high water consumption. Detects leaking taps and valves.
