Installation II (
remodeling
)
1.
In case there is a ventilation unit with the same dimensions in the ceiling,
proceed as follows:
Remove the old unit;
Check the existing duct work and electrical wiring;
Install the unit as described in Installation I.
2.
In case you want to make a new opening in existing ceiling:
Find the best location for the ventilation purpose;
Make sure that :
−
the chosen place has easy access
to exterior air outlet (wall cap or roof
jack) and there will not be a need
for sharp angles or very long duct;
−
the chosen place for the duct work will
not interfere with any other existing
duct work in the
building;
−
there is no electrical wiring or
any pipes behind the chosen place;
Open the optimal place.
Be careful to
cut the hole exactly. If the hole is too
big, the fan grille will not hide it;
Make the strong support beams for
the unit (make sure it is strong enough
for the weight of the unit);
Provide the duct system and electrical wiring;
Follow the instructions on Installation I.
