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.

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, 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.
4. Cautions about MCU installation.
When fixing the unit at the upper place using suspension bolts, use a nut and washer to vertically fasten the unit.
There are four spots to fix the suspension bolts. Make sure every spot is fixed.
The upper and the lower side of MCU is distinguished, so be careful not to turn the unit upside down when installing the
unit. Otherwise, noise may be generated or the product may be damaged.
