How to purge the DHW system
from limestone deposits
To clean the DHW system it is not necessary to remove the DHW heat
exchanger if the assembly is equipped with the appropriate taps (supplied
on demand) placed on the hot water outlet and inlet.
To carry out the purge it is necessary to:
• close the cold water inlet
• drain the DHW system from the water contained therein by means of
a hot water tap
• close the DHW outlet
• unscrew the two stop cocks caps
• remove the filters.
In case the appropriate tap is not supplied it is necessary to disassemble
the DHW heat exchanger, as described in the following section, and do
the purge aside. We recommend you also purge from limestone deposits
the DHW heat exchanger seat and the NTC sensor fitted on the DHW
system.
