Indoor unit installation

AA
When deciding on the location of the air conditioner with the owner, the following restrictions must be taken into account.
1. Determine the position of the pipe and drain hose hole as seen in the
picture and drill the hole with an inner diameter of 65mm so that it slants
slightly downwards.
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.
• The distance between a suspension bolt and the top of
bracket (in indoor unit) not exceed 25mm(between indoor
pipe and hanger plate).
4. Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
CAUTION
• You must install all the suspension rods.
• It is important to leave sufficient space in the false ceiling to
allow access for maintenance or repairs to the drainage pipe
connection, the refrigerant pipe connection, or to remove the
unit if necessary.
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.
1) Place the pattern sheet on the indoor unit.
2) Adjust a space between the ceiling and the indoor unit by using the
gauge of dimensions.
3) Fix the indoor unit securely after adjusting level of the unit by using a leveler.
4) Remove the pattern sheet, connect the other cables and install the front panel.
