Air Distribution Concepts Flush Rail - Manual (Page 3)

STEP FOUR: START UP
Turn on air handler and inflate diffuser. If the diffuser system flutters after installation, check to see if
air handler is operating at its designed air volume and static pressure. Fluttering can cause damage to
fabric shortening life of system.

STEP THREE: INSTALLATION OF FABRIC DIFFUSER
When handling a diffuser prior and during installation, please keep anything that comes in contact with the diffuser
clean. If a diffuser is to be laid out on the floor, make sure floor is clean or something is laid down to protect diffuser
from dirt or debris on the ground that could catch on air jets and damage diffuser during installation.
1.) Slide the cord down through the rail.
2.) Pull diffuser down the rail until fully extended.
3.) Pull open end of diffuser and slip over metal collar or metal duct (about 6-12”).
4.) install worm gear band around diffuser to secure it to metal duct.
Note: Worm gear bands are perforated and self taping screws can be used to help secure band and
keep from slipping. ( screws not included).
5.) Finish rail installation by trimming off end end with angle piece. Anchor end piece to rail with screws and
anchors provided. Note: Angle end piece should be 2” wider then diffuser.
