7.2.2 ADJUSTING THE GRILLES

In YLV, YLV/AF, YLH, YLH/AF and YLVR models, the grilles located on the air outlet can be turned
in to all 4 directions, by simply lifting the access door on the left-hand side of the housing, sliding
the grilles and removing them. When removing a grille, pay attention not to break the little feet
underneath. The grilles can then be replaced in the desired position.

7.2.3 CLEANING THE COIL

Every year, verify that the fin pack is not clogged from dust or anything else that does not allow
the normal air flow; if necessary, use a jet of compressed air to clean the heat exchanger. To
prevent damage to the fins or the pipes on the heat exchanger, never use steel tools or sharp
objects to clean the spaces between the fins.
