6.2 SHUTTER AND FAN CLEANSING
After having cleaned the filters and the heat exchanger, reposition them in their places. Take
the main unit assembly (1+2+3) and the esthetic front cover (1), by pulling out the upper
hooks and then the lower ones.
By means of a flat screwdriver, pry on the shutter attachment teeth (2) to remove it from the main
unit (3).
Wipe the shutter's grill (2) with a dry cloth to eliminate dust or dirt residues in general.
Carefully reinstall the wall mounting in its place. There must be two "clicks" signalling the tooth
attachment.
Wipe the fan blades belonging to the main unit (3), with a dry cloth.
