3. Selecting an installation site & Accessories
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.

a Indoor unit
b Outdoor unit
Refer to the Instruction Manual that came with the outdoor unit for the restrictions on
the height difference between units and for the amount of additional refrigerant
charge.
Avoid the following places for installation where air conditioner trouble is liable to
occur.
• Where there is too much oil such as for machine or cooking.
• Salty environment as seaside areas.
• Hot-spring areas.
• Where sulfide gas exists.
• Other special atmospheric areas.
• This unit has flared connections on both indoor and outdoor sides. [Fig. 6-1]
• Insulate both refrigerant and drainage piping completely to prevent condensation.

• 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).
a Reinforcing the ceiling with additional members (edge beam, etc.) must be
required to keep the ceiling at level and to prevent the ceiling from vibrations.
b Cut and remove the ceiling members.
c Reinforce the ceiling members, and add other members for fixing the ceiling
boards.

5.2. Confirming the unit's position and fixing hanging
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:
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.
Piping preparation
• Refrigerant pipes of 3, 5, 7, 10 and 15 m are available as optional items.
