DANGER
In case of a malfunction, always determine the
reason for the malfunction before restarting the unit.
WARNING
When you have switched off the power to the

maintenance work. Even though the power is
switched off, the fans continue running and the
post-heating coil remains hot for a while.
WARNING
Check that the unit is completely isolated from
the mains supply before conducting any voltage
tests, insulation resistance measurements or other
electrical work or measurements. Such work may
damage the sensitive electrical equipment.

Control equipment used in the ventilation units
may cause leakage current. This may affect the
operation of the residual current protection.
CAUTION
All ventilation units containing a control system
must be equipped with an overvoltage protector.
