7.3 Installation of the defroster heating
7.4 Putting into operation
7 Installation instructions
The wireless remote control optionally available for the profi-air 180 flat ventilation unit is
required to put the defroster heating into operation.
The heating spiral must be regularly inspected during maintenance (prior to the beginning of the heating period). The defroster heating or
the ventilation unit must be disconnected from the network for maintenance work. If there is dirt on the heating spiral, it can be cleaned
with a suction nozzle and a vacuum cleaner.
For more information on putting into operation, see the 180 flat
wireless remote control operating instructions.
Do NOT clean the heating spiral with a dry or wet cloth.
After disconnection from the network, the heating spiral may still be hot.
Please allow it to cool sufficiently, otherwise burn injuries may happen.
Electrical connections must be established by authorised and qualified personnel and in the “dead” state of
the ventilation unit only. In addition, applicable local regulations and safety provisions must be complied with.
