SAFETY
General Electrical safety
Always check that the equipment supply voltage is switched off before opening the service hatch.
Only an authorised electrician may perform any actions in the electrical box.
Follow the local regulations on electrical installations.
In case of malfunction, always find out the reason for the malfunction before starting the unit again.
Wait for two (2) minutes after switching off the power of the unit before commencing the maintenance. Although the power is switched off, the fans continue running and the heating element stays hot for a while.
Check that the unit is entirely isolated from the mains before conducting any voltage tests, insulation resistance measurements or other electrical work or measurements. Such work may damage the sensitive electrical devices.
Control devices used in the ventilation units may cause leakage current. It may affect the operation of the residual current devices.
All ventilation units with a control system must be equipped with an over-voltage arrester.
