Indoor Unit Installation
• Indoor Unit Lifting
1) Please use such tools as the pulley to lift the indoor unit
to the draw bolts.
2) Please use such tools as the level gauge to adjust the
indoor unit to the level, otherwise, water leak may occur.
• Piping
• When the pipe goes through the wall, wall bushing should be
used to prevent the insulation from being damaged by the wall
which may result in poor insulation and condensate water.
CAUTION
Drain hose port
When drain hose is installed on the right side.

It is recommended to install the Y-joint before installing the indoor unit.
1. Place the pattern sheet on the ceiling 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,
maintain the correct measurements between the markings
before drilling the holes.
NOTE
2. Insert bolt anchors, use existing ceiling support or construct a suitable
support as shown in the gure.
3. Install the suspension bolts depending on the ceiling type.
• 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 suspension bolt length is more than 1.5m, it is required to
deploy vibration prevention measures.
CAUTION
4. Screw eight nuts to the suspension bolts and make space for hanging
the indoor unit.
• You must install more than 4 suspension bolts when installing the
indoor unit.
CAUTION
5. Hang the indoor unit to the suspension bolts between two nuts.
• Piping must be laid and connected inside the ceiling when
installing the indoor unit. If the ceiling is already constructed,
lay the piping into the position for connection to the unit before
placing the unit inside the ceiling.
NOTE
6. Screw the nuts to suspend the indoor unit.
7. Adjust the level of the unit by using measurement plate for all 4 sides.
• For proper drainage of condensate, give a 1° slant to the left or
right side of the unit which will be connected with the drain
hose, as shown in the gure. Make a tilt when you wish to
install the drain pump, too.
