Table 11 : Cooling components depending on the active filter model.
The following symptoms in the behaviour of the filter can indicate wear in the
fans or turbines:
Increased noise in the fan / turbine.
Increased temperature in the unit under the same environmental
conditions and load.
The AFQ-4W periodically indicates the temperature alarm.
If any sign of wear is detected, the affected fan/turbine should be replaced.
