FIL FIL FILTERS FIL FIL TERS TERS TERS TERS
The CLIMATIC™ 2 controls the filters. Two types of problems
may occur :
1 - 004 error code (lit LED "filter") or the following icon (for a
graphics screen - KP07) :
Item 8 on KP 17 indicates that the filters must be changed.
The unit has not stopped but the airflow is likely to be reduced
due to increased pressure drop acros the filters.
2 - 005 error code or the following icon
(for a graphics screen - KP07) :
Item 29 on KP17 indicates that the filters are out of position
: either they have been damaged or not been replaced
during maintenance. In the latter case, the unit has not
stopped but the increased flowrate may result in the motor
overheating. It is important to check the filter immediately.
FILTER REPLACEMENT
After opening the filter access panel, unscrew the butterfly
nuts maintaining the filter support and remove it (figure 34).
Remove the cells that are slide-mounted (figure 34).
Use the rod in the lower filter section to remove the cells at
the botton of the sliders.
Install new filters inside the sliders.
