Installation of the ducts
・
Use the tapping screws included with the
ducts to mount the ducts directly to the ceiling(or wall).
・
Use all of the mounting holes.
・
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.
Mounting the pipe-suspended hangers 1
・
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.
・
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.

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.

Mounting the ducts directly to the ceiling
Support spacing for the duct
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.
●
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.
Caution
●
Securely fasten the wood screw or tapping
screw, pan head machine screw, and setscrew.
Caution
Notes
●
Do not attach the plug unit with the place where
the tapping screws were mounted.
