When special chemical product may scatter around such as site chemical
plants and hospitals, full investigation is required before installing unit. (The
plastic components 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 (dew point above 26 °C [79 °F]), dew condensation
may be produced in the indoor unit. When operating the units in this condition,
add insulation material (10 - 20 mm [13/32 to 13/16 in]) to the entire surface of
the indoor unit to avoid dew condensation.
3.1. Install the indoor unit on a ceiling
strong enough to sustain its weight
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.

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.

6. Refrigerant pipe and drain pipe specifications
To avoid dew drops, provide �����
refrigerant and drain pipes.
When using commercially available refrigerant pipes, be sure to wind
commercially available insulating material (with a heat-resisting temperature of
more than 100 °C [212 °F] and thickness given below) onto both liquid and gas
pipes.
Insulate all indoor pipes with form polyethylene insulation with a minimum density
of 0.03 and a thickness as ���� in the table below.

3.2. Securing installation and service space
•
Select the optimum direction of supply ��� according to the ������ 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 ���� suspension work and safety, provide a space as much as
possible.

3.3. Combining indoor units with outdoor
units
For combining indoor units with outdoor units, refer to the outdoor unit installation
manual.
Hanging structure
•
Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
•
If necessary, reinforce the hanging bolts with anti-quake supporting members
as countermeasures against earthquakes.

5.2. Confirming the unit's position and
fixing hanging bolts
► 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.
1 Select the thickness of insulating material by pipe size.
Pipe size
6.4 to 25.4 mm [1/4 to 1 in]
28.6 to 38.1 mm [1-1/8 to 1-1/2 in]
2 If the unit is used on the highest story of a building and under conditions of
high temperature and humidity, it is necessary to use pipe size and insulating
material's thickness more than those given in the table above.
