When unloading the unit, it is strongly recommended that sudden movements are avoided in order to protect the refrigerant circuit, copper
tubes or any other unit component. Units can be lifted by using a forklift or, alternatively, using belts. Take care that the method of lifting does
not damage the side panels or the cover. It is important to keep the unit horizontal at all time to avoid damage to the internal components.
In the below drawing, the typical ceiling installation is shown (typical for residential buildings, of
fi
ces etc.) where the unit is hanging thanks
to the help of 4 brackets supplied standard. The brackets must be connected to the vibration dampers which have to be chosen according
to the kind of structure they will be
fi
xed to. It’s advisable to cover the inside of the false ceiling with high density bitume layer and to foresee
one or more openings to have the possibility to clean the air
fi
lters, to control the refrigerant circuit and to check the electrical board.
