Siting information
!
Please note
The thermal insulation must not come into con-
tact with naked flames.
Exercise caution when welding and brazing.
!
Please note
To prevent material losses, site the DHW cylin-
der in a room free from the risk of frost and
draughts.
Alternatively, drain the DHW cylinder when not
in use and there is a risk of frost.
■ Allow an adequate distance from the wall to enable
the temperature controller (if supplied) to be oper-
ated.
■ 750 and 950 l capacity:
For replacing the magnesium anodes, ensure a
clearance of
at least 850 mm in front of the DHW
cylinder.
■ Use the adjustable feet to level the DHW cylinder.
Note
Never extend the adjustable feet beyond a total
length of 35 mm.
