Installation of Indoor Unit Main Body and Suction Chamber
• Install the indoor unit main body and suction chamber.
At the time of installation, perform the engineering work according to the installation
manual attached to the indoor unit main body. (For the installation height, refer to the figure
to the right.)
• When mounting the suction chamber to the existing indoor unit main body, change the
installation height of the indoor unit main body to height
Mounting of Connecting Chamber and Connection of Flexible Duct

Duct Connection
(1) Connect the duct to the duct connection area.
(2) Wrap the connection area with vinyl tape, etc., (arrangement at site) to prevent an air leak.
Precautions
•
For the duct, be sure to apply the insulation treatment to prevent condensation.
• Do not perform duct manipulations described in the figure to the right.
• Beware that, in accordance with the local law, there may be cases where the use of a nonflammable duct is
compulsory.
•
When a duct goes through fire protection areas including a fire proof structure, beware that, in accordance with the local law, it may be required to establish a damper or to build a
structure that is not detrimental to fire protection.
• When penetrating a wooden construction wall with a metal duct, apply electrical insulation to the duct and wall.
• Mount the outside duct so that it has a downslope toward the outside, and prevent rainwater from leaking in with a hood, etc. (Gradient of 1/100 to 1/50)
• To prevent the intrusion of small animals, such as birds, and bugs, be sure to attach a netting to sections open to outside air.
•
To protect the heat exchanger of the indoor unit, be sure to attach an air filter to sections open to outside air.
Mounting of Decoration Panel
• After temporarily hooking the decoration panel, pass the swing motor lead wire, which is coming out from the decoration panel, through the wiring hole of the suction chamber.
However, when used in combination with the air purifier unit or streamer deodorization unit, perform wiring without routing through the wiring hole.
• Mount the decoration panel according to the installation manual attached to the decoration panel.

(1) Wrap the sealing pad (2) Insert the tip of the
to the position to be band through the
tightened. gap of the split pin,
then lightly tighten
by hand.
Precautions
Because the split pin has a structure to prevent counter rotation, be careful with the
turning direction. (When a counter rotation is forced, the ratchet will be damaged, and
the tightening force will be weakened.)
(4) Mount the supplied installation pattern paper to the indoor unit by using screws to
cure the indoor unit.
(Refer to the installation manual of the indoor unit main body.)
(Refer to the figure below.)
(Mounting of installation
pattern paper)
• Complete all the refrigerant and drain piping works for the indoor unit main body.

With wireless unit
• For details on connection method, refer to the installation manual
attached to the wireless remote control kit (sold separately).
