• 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.
• 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 1.5 m(4.92 ft), 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.
CAUTION
4. Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
• You must install the suspension bolts more than four 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
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.
NOTE
6. Screw the nuts to suspend the unit.
7. Adjust 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 figure. Make a tilt when you wish to install the drain
pump, too.
