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.
4 Screw eight nuts to the suspension bolts making space for
hanging 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. 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.

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.
CAUTION
You must install all the suspension rods.
