Safety instructions
Operating the air treatment unit and accessory components
WARNING
Before the air treatment unit is taken into service, any free connections must be provided
with protective nets.
The air treatment unit must also not be taken out of service until all electrical and mecha-
nical safety devices have been fitted.
If any interventions are required, check that the voltage supply to the unit is interrupted. Note that
any electrical air heaters have a separate electrical supply, which is not interrupted via the air treat-
ment unit’s main switch.
Great care must be taken when opening the venting connections for heating water to an air heater.
Risk of fluid hammering.
In conjunction with service or inspection, the main switch of the unit must be turned off before ope-
ning the inspection doors. Before restarting, all safety devices must be refitted.
A free space (safety distance) must be maintained in front of electrical heaters and electrical control
cabinets according to the applicable electrical safety regulations.
Use the control display to stop the unit.
The unit’s hatches are provided with a locking handle. Ensure that the unit is always left in the
locked position.
Inspection hatches on filter/fan parts must not be opened when the unit is running, in view of the
major risk of overloading the fan motor. There is also a risk of personal injury or damage to the fan
due to objects being sucked in.
