Precautions
• This product can be mounted to a ceiling mounted cassette-type air conditioner <round flow>.
According to the table to the right, check the model name of the indoor unit, then mount the product.
•
At the time of mounting, also refer to the installation manual for the indoor unit main body and to the
one for the decoration panel.
• For the duct (field supplied) to be connected, those specified in the table to the right are recommended.

Preparation Before Installation
• With this branch duct chamber, the blow directions shown in the
figure to the right can be selected.
Select the blow direction that is most appropriate for the room
shape and installation position. (Blow directions other than those
in the figure to the right cannot be selected.)
• From the external static pressure/air volume characteristics (refer
to the technical guide), select the duct length and air outlet.
Precautions
• Be sure to securely block the air outlet of the indoor unit main
body to which the branch duct chamber is mounted. If the
blocking is incomplete, water spraying or condensation may
occur. Do not block the corner sections.
(Refer to
Mounting of Sealing Material to Indoor Unit
• When mounting the branch duct chamber, be sure to perform field
setting of the indoor unit main body.
(Refer to .)
Field Setting
Mounting of Branch Duct Chamber
When an installation is performed after mounting the branch duct chamber to the indoor unit main body
(at new installation), do not apply force to the branch duct chamber. (Deformation may occur.)
(1) Select the position where the branch duct chamber is mounted.
(2) Mount the branch duct chamber to the indoor unit according to the following procedure. ( Figure 2 is an
example of the face 1 side.)
1) Along the slit, cut the side plate of the indoor unit to which the branch duct chamber is mounted. Then,
cut the internal insulator along the groove.
(Use nippers, etc., to cut the slit section, and cutter, etc., to cut the groove section.) Figure 2
For the port opening operation, do not use a tool that produces chips, such as a saw. The drain system may become clogged, and a water
leak may occur.
2) Use the sealant for sticking so that the gaps between the side plate and internal insulator are filled around the full circumference. Figure 3
• First, stick the main body's opening sealant 4 to left and right of the opening, and the main body's opening sealant 5A ( 5B ) to the upper and lower sides of
the opening.
At this time, fold the main body opening sealant towards the inside so that the gap between the side plate and internal insulator is no longer visible.
