CHECKING THE STATE OF AIR FILTERS
Depending on the environment in which the internal unit is
installed, the air filters must be cleaned periodically.
In particularly dusty atmospheres, the air filters should be
cleaned every three months and you are recommended to
have a differential pressure switch installed to indicate
when the filters are dirty.
Removing and cleaning filters
1. Remove the fixing screw, then the door.
2. Remove the air filter gently from the bottom, avoiding
dispersion of dust in the atmosphere.
3. Wash the filtering layer with warm water and ordinary
detergent, rinse and dry thoroughly.
4. Replace the filter
5. Replace the door and fix with the screw.
3. Check the fixing of external panels.
4. Check that fixing elements are not causing excessive
noise and/or vibrations.
5. Check that the condensate is draining correctly and
that the pan is free from encrustation.
6. Check that the power supply cable is in good condition
without cracks or lacerations. This should be done by
qualified personnel only.
