STEP ONE: INVENTORY
Before installing fabric diffuser system read all general information in the following
sections. For best results use this manual in conjunction with the mechanical blue
print or diffuser layout if supplied.
Check the shipment carefully. Diffuser systems are shipped in polyethylene bags or
boxes. Larger orders will be shipped in large skidded containers with individual contents in polyethylene bags or folded. All packages will be labeled with diffuser diameter and length.
Make sure contents match the packing list. Note any missing or damaged pieces and
notify your supplier before starting installation. Check length & diameters before installing & contact supplier before installation. (Not responsible for labor costs accrued
from installing incorrect lengths or layouts.)
STEP TWO: SUSPENSION HARDWARE
The aluminum flush rail supplied comes in 10 foot sections. Identify rail location and mounting
locations. D-shape systems require side mounting based on 3:00 and 9:00. flush mount rail
must be mounted to a flat surface. Rail can be mounted with rivets or screws to T-Bar or flat
surface of ceiling. If D-shape diffuser is not mounted to a flat surface it will not retain it’s half
round shape. Rails should be mounted the width of the diffuser. The inside distance between
the rails is equal to the diameter minus 1 3/4”. Diffusers can be supplied with air from end or
from top flat area of diffuser. ( See below).
Fittings
When fabric fittings are incorporated in your installation, align rails off centerline of
the system. When elbows are used in the system rail should be installed as indicated
as above. Rail bends and precut rail sections will be provided for suspension of the
elbows. (Note: rail bends may come in two sections, a coupler may be needed to
connect.)
When tee’s or take offs are used Install rail perpendicular to main rail to suspend
branch runs. To insure proper alignment the main of the fabric system can be installed to the rail and the air handler first. Then the cross rails perpendicular to the
main can be installed to suspend the branch runs. Fittings will have quick connect
joints such as zippers to ease the installation and maintenance of the system.
