Indoor unit installation
It is recommended to install theY-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,
NOTE
before drilling the holes maintain the correct dimensions
between the markings.
• Pattern sheet is supplied depending on the model type.
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.
CAUTION
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.
• 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.
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,
NOTE
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.
