Installing the heating water buffer cylinder
Installation information
Danger
Intense heat from a naked flame will melt the
thermal insulation. The resulting vapours may
be harmful to health.
Prevent the thermal insulation from coming into
contact with naked flames, e.g. when welding
and brazing.
!
Please note
To prevent material losses, install the heating
water buffer cylinder in a room free from the risk
of frost and draughts.
When not in use, the heating water buffer cylin-
der must be drained if there is a risk of frost.
