CLEANING AND MAINTENANCE
Before maintenance, make sure the power of the unit is turned off.
Only qualified specialists can intervene.
The only component of the cassette that needs cleaning and maintenance is the filter,
placed on the air intake (unless there is the breakage of other components).
The filter must be cleaned with every season change, using a vacuum-cleaner or brushing it.
To perform this operation, follow the steps below:
- With the help of a flat-blade screwdriver rotate of 90º the locks placed on the intake grid
of the front panel as shown in Fig. L.;
- remove the filter from the inner rails, being careful not to break them as shown in Fig.
M.;
- Once cleaned, re-insert the filter into the guide and close the grid by turning the locks of
90º in the opposite way than the opening.
- Always reassemble the filter after cleaning it before restarting the cassette.
