WARNING
Before switching on the fan, make sure that the inlet and outlet of the fan section have
been connected to the ductwork or that the access to the rotating fan parts, such as the
impeller, through an inlet, outlet or access door has been prevented with protective
screens or by other appropriate manner. The service switch of the air handling unit must
be installed and in service when the unit is switched on. The damper section of the unit
must open before the fan starts.
WARNING
Do not keep extra objects on top of or inside the unit. Do not climb or walk on top of the
unit.
WARNING
The earthing continuity of the frame of the ventilation unit must be assured, and the frame
must be connected to the building’s earthing system before operation.
WARNING
The supply cables of the ventilation unit must be equipped with a correctly dimensioned
safety switch that can be used to stop the unit before starting any maintenance work. Upon
starting the unit, the safety switch of the unit must be installed and operating and the
access doors closed.
WARNING
The electric motors are serviced according to the manufacturer’s instructions. The
components must be de-energised and the impeller stopped for the duration of the
maintenance. Once opened, the rotors and stators of the EC motors may cause interference
in electrical devices, such as mobile phones and payment cards. Being in close proximity to
opened permanent magnet motors constitutes a danger to people with pacemakers.
