Instllation Procedure
Installation of the ducts
1
Mounting the ducts directly to the ceiling
・ Use the tapping screws included with the
ducts to mount the ducts directly to the ceiling(or wall).
Caution
Fix the duct to building structure firmly.
●
It will become a cause of fall if it does not so.
・Use all of the mounting holes.
Notes
Do not attach the plug unit with the place where
●
the tapping screws were mounted.
・Screw one screw partway in, fit the elongated hole of
the duct onto that screw, and then screw the other
screw in through the round hole in the duct. This allows
the installation to be completed by one person.

・Use this procedure if the Factory Line 20 ducts
are to be suspended from pipes, If necessary, the
pipes can be shortened to the required length by
cutting them at the flange end.

Support spacing for the duct
・The standard interval for mounting of the hangers is 1 m, and the maximum
interval is 1.5 m. Be sure to mount securely to a structural member.
Caution
Ensure the strength of building structures enough to support
●
the hanging weight (a maximum of 10kg per support).
Not doing so may cause the hanger to drop.
Use two or more pieces of hanger for one duct.
●
I It will become a cause of fall if it does not so.
To prevent the ducts from meandering, align the hanger centers.
●
Not doing so may cause the hangers to drop.
Installation the flanges
1.Turn the flange cover to the left to remove it.
2.Use the wood screw or tapping screw ,then mount the flange to a
structural member.
3.Align the pipe mounting hole of the pipe suspension hanger with the
position of the pan head machine screw to put the pipe in the flange,
and then fasten the pan head machine screw and the setscrew.
(Fasten the pan head machine screw through the pipe mounting hole.)
4.Turn the flange cover to the right to mount it back in its
original position.
Caution
Securely fasten the wood screw or tapping
●
screw, pan head machine screw, and setscrew.

●Adjust the length the pipe-suspended hangers after mounted
・In order to adjust the length after the pipe- suspended
hangers have been mounted to a structural member,
loosen the securing screw, remove the pipe, and cut
the pipe at the flange end.
●After cutting, drill a hole
( φ 5.5 mm), mount the
flange, and then mount a
pipe to the flange.
