Maintenance
Attention!
Potential material damage due to improper care!
►
Do not clean plastic parts with solvent-based detergents.
The fully automatic filling system for heating installations automatically signals
a spent cartridge, which only has to be refilled. By using the connection set for
heating water conditioning, it is possible to fill the cartridge without draining the
installation
The new refill granules for softening or complete demineralization must be
ordered in the corresponding size in accordance with the size and type of the
cartridge.
7.1
Maintenance of the backflow preventer
The backflow preventer type BA must be serviced once a year according to DIN
EN 806, part 5.
The correct functioning of the installation is checked after the first year of ope-
ration, then periodically depending on the operating conditions. At the latest,
however, maintenance must be done after one year. We recommend to use
our differential pressure measuring case (serial no. 6600.00.911, can be loaned
over a period of 14 days)
The testing equipment in each pressure zone serves to verify the functioning of
the valve with the respective measuring devices. Due to the design of the back-
flow preventer type BA with cartridge technology, maintenance proves simple
and easy
►
Close the isolating valves upstream (1) and downstream (2) of the backflow
preventer.
►
Remove both manometer plugs (3) on the test ports.
►
Install the two maintenance ball valves (4).
