materials and materials containing aluminium. If there is a risk
of water contamination during operation, it may be necessary
to install a filter.

as all electrical installations, must have been carried out
correctly and fully completed.
Fill the domestic hot water circuit via an external connec-
tion.
Purge the domestic hot water circuit (open domestic hot
water taps at the highest extraction points until there are
