2. Installing the indoor unis
3. Preparation before installation.
1) Place the pattern sheet on the ceiling at the spot where you want to install the
indoor unit.
• Since the diagram is made of paper, it may shrink or stretch slightly due
to temperature or humidity. For this reason, before drilling the holes
maintain the correct dimensions between the markings.
2) Insert bolt anchors, use existing ceiling supports or construct a suitable support
as shown in figure.
Concrete
Hole in anchor
Hole in plug
Suspension bolt(3/8" or M10)
Insert
3) Install the suspension bolts depending on the ceiling type.
Ceiling support
• Ensure that the ceiling is strong enough to support the weight of the
indoor unit. Before hanging the unit, test the strength of each attached
suspension bolt.
• If the length of suspension bolt is more than 1.5m(4.92'), it is required
to prevent vibration.
• If this is not possible, create an opening on the false ceiling in order to
be able to use it to perform the required operations on the indoor unit.
