Indoor Unit Installation
It is recommended to install the Y-joint before installing the
indoor unit.
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.
Note
2.
Insert bolt anchors, use existing ceiling supports or
construct a suitable support as shown in figure.
3.
Install the suspension bolts depending on the ceiling type.
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.
Screw eight nuts to the suspension bolts making space for
hanging the indoor unit.
You must install the suspension bolts more than
four when installing the indoor unit.
5.
Check the level of the indoor unit by using a leveler.
A tilt of the indoor unit may cause malfunction of a
built-in float switch and water leaks.
6.
Adjust the height of the indoor unit by using the gauge of
dimensions.
You should adjust the gauge of dimensions and the
pattern sheet to fit the cutting dimensions of ceiling.
Make sure that the indoor unit is installed at a level if the
indoor unit slants too much, there can be water leaks.
