A I ndoor 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 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
'A' 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.
