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.
Ceiling support
t
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.
t
If the length of suspension bolt is more than 1.5m (4.92 ft), it is
required to prevent vibration.
t
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.
CAUTION
4. Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.

Fasten the nut
t
You must install the suspension bolts more than four when
installing the indoor unit.
CAUTION
5. Check the level of the indoor unit by using a leveler.
t
A tilt of the indoor unit may cause malfunction of a built-in float switch
and water leaks.
