Indoor Unit Installation
It is recommended to install theY-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.
Note
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.
3
Install the suspension bolts depending on the ceiling type.
CAUTION
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 4.92ft(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.
CAUTION
You must install the suspension bolts more than four when
installing the indoor unit.
5
Hang the indoor unit to the suspension bolts between two nuts.
Note
Piping must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay the
piping into position for connection to the unit before
placing the unit inside the ceiling.
6
Screw the nuts to suspend the unit.
7
Adjust level of the unit by using measurement plate for all 4 sides.
Note
For proper drainage of condensate, give a 0.12inch(3mm) slant to
the left or right side of the unit which will be connected with the
drain hose, as shown in the figure. Make a tilt when you wish to
install the drain pump, too.
