Indoor unit installation
It is recommended to install the refnet 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.
4
Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
CAUTION
You must install all the suspension rods.
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. Cut a pad stopper and place it on the
bracket at this time.
7
Adjust the unit to the appropriate position considering the installation area
for the front panel.
7-1 Place the pattern sheet on the indoor unit.
7-2 Adjust a space between the ceiling and the indoor unit by using the gauge
of dimensions.
7-3 Fix the indoor unit securely after adjusting level of the unit by using a leveler.
7-4 Remove the pattern sheet, connect the other cables and install the front
panel.
