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
A) Single Suspension Hardware
The cable supplied is .1875 dia. (7x7) aircraft cable, (vinyl coated or stainless cable may also be supplied). The orientation (12 o, clock ) suspension cable should be positioned 3.5” (standard) above the surface of the diffuser. If plastic or
stainless steel snap hooks are specified, position cable 3” above the surface of the diffuser. Cable must be aligned with
the centerline of the airflow. If diffuser bounces for the first 20’-30’ it is not anchored with the airflow. Move the end of the
cable. Locate and secure end points of the cable run with eyebolts at required locations. Install eyebolt to turnbuckle and
turnbuckle to cable and cable to eyebolt. Turnbuckle is used at one end to tighten cable.
General Note: one 1/2” x 6” turnbuckle for every 100’ of length
Multiple turnbuckles may be required. Vertical cable supports can be installed to prevent cable from sagging. Number of
supports depends on desired cable levelness. Vertical supports cannot be installed until diffuser has been hung and inflated. Cable tension can be estimated by the amount of sag of the cable over the length installed.

When fabric fittings are incorporated in your installation, align cables with the centerline of the system. All
cables should be installed at the same elevation.
When elbows are used in the system cable should be installed as indicated as above. It is recommended
to inflate system before suspending elbow. Make sure elbow is fully inflated without kinks. Then use cable to support the elbow from the snaphooks in the elbow seams to the suspension cable where needed to suspend elbow
when system is deflated. A cable can be installed with cable clamps from one cable to the other at a 45 degree
angle above elbow to help suspend elbow. Starting from where the seam of the elbow begins measure (.414)x
(radius of elbow) and clamp the cross cable. Then connect the cross cable to the cable perpendicular to first cable. It should be connected to that cable the same distance coming from the other end of the elbow. Use short
lengths of cable or “S” hooks to attach “O” rings to the cable.
When tee’s or take offs are used install cables as above. Install cable perpendicular to main cable to suspend branch runs. To insure proper alignment the main of the fabric system can be installed to the cable and the
air handler first. Then the cross cables perpendicular to the main can be installed to suspend the branch runs.
If the take off port is top even all snap hooks will be the same distance of the diffuser. If the take off port is centered on the side of the main, the snap hooks are normally extended the same level as the snap hooks of the
main duct. Fittings may have quick connect joints such as zippers to ease the installation and maintenance of the
system.
