Basic safety instructions
Only an approved heating engineer is permitted to carry
out installation and repair work on the unit. The existing
regulations, rules and guidelines must be observed when
doing so.
Preventing malfunction
>
Only operate the heating installation when it is in a tech-
nically perfect condition.
>
Ensure that any faults and damage that affect safety are
rectified immediately.
Preventing frost damage
If there is a power cut, or if the room temperature is set too
low in individual rooms, it can not be ruled out that sections
of the heating system might be damaged by frost.
>
If you are going to be away during a cold period, make
sure the heating system remains in operation and that
the rooms are sufficiently heated.
>
Always observe the information on frost protection
(
¬ section 3.2
).
Even if rooms, or the whole dwelling, are not in use for cer-
tain periods, the heating must remain in operation!
Caution!
Frost protection and monitoring devices are only active
when the unit is supplied with power. The mains switch
on the unit must be set to the position "I".
