3. Selecting an installation site & Accessories
• Select a site with sturdy fixed surface sufficiently durable against the weight of unit.
• Before installing unit, the routing to carry in unit to the installation site should be
determined.
• Select a site where the unit is not affected by entering air.
• Select a site where the flow of supply and return air is not blocked.
• Select a site where refrigerant piping can easily be led to the outside.
• Select a site which allows the supply air to be distributed fully in room.
• Do not install unit at a site with oil splashing or steam in much quantity.
• Do not install unit at a site where combustible gas may generate, flow in, stagnate
or leak.
• Do not install unit at a site where equipment generating high frequency waves (a
high frequency wave welder for example) is provided.
• Do not install unit at a site where fire detector is located at the supply air side. (Fire
detector may operate erroneously due to the heated air supplied during heating
operation.)
• When special chemical product may scatter around such as site chemical plants
and hospitals, full investigation is required before installing unit. (The plastic com-
ponents may be damaged depending on the chemical product applied.)
• If the unit is run for long hours when the air above the ceiling is at high temperature/
high humidity (due point above 26 °C), due condensation may be produced in the
indoor unit. When operating the units in this condition, add insulation material (10-
20 mm) to the entire surface of the indoor unit to avoid due condensation.

* If the optional long-life filter is installed, the dimensions of the air conditioner
increase.

5. Installing the unit
5.1. Hanging the unit body
Bring the indoor unit to an installation site as it is packed.
To hang the indoor unit, use a lifting machine to lift and pass through the
hanging bolts.

Warning:
The unit must be securely installed on a structure that can sustain its weight. If
the unit is mounted on an unstable structure, it may fall down causing injuries.
3.2. Securing installation and service space
• Select the optimum direction of supply airflow according to the configuration of the
room and the installation position.
• As the piping and wiring are connected at the bottom and side surfaces, and the
maintenance is made at the same surfaces, allow a proper space properly. For the
efficient suspension work and safety, provide a space as much as possible.
3.3. Indoor unit accessories
The unit is provided with the following accessories:
No.

• If necessary, reinforce the hanging bolts with anti-quake supporting members as
countermeasures against earthquakes.
* Use M10 for hanging bolts and anti-quake supporting members (field supply).
1 Reinforcing the ceiling with additional members (edge beam, etc.) must be re-
quired to keep the ceiling at level and to prevent the ceiling from vibrations.
2 Cut and remove the ceiling members.
3 Reinforce the ceiling members, and add other members for fixing the ceiling boards.

5.2. Confirming the unit's position and fixing hanging
bolts
Use the gage supplied with the panel to confirm that the unit body and
hanging bolts are positioned in place. If they are not positioned in place, it
may result in dew drops due to wind leak. Be sure to check the positional
relationship.
Use a level to check that the surface indicated by A A A A A is at level. Ensure that
the hanging bolt nuts are tightened to fix the hanging bolts.
To ensure that drain is discharged, be sure to hang the unit at level using a
level.

Caution:
Be sure to install the unit body at level.
