Important Safety Information:
Always use proper safety equipment when installing Quick-Fit:

STEP ONE: Make Sure Your Shipment is Complete and Undamaged.
Additionally, before signing for your shipment, ensure that all boxes are accounted for. You can find the number of boxes in a shipment by checking the delivery receipt the driver will ask you to sign. Again, note any discrepancies before signing. Important safety note: Beware of the sharp metal staples used to seal the shipping boxes.

STEP TWO: Review the Packing Documents.
Nordfab packs boxes with the goal of reducing shipping costs, not in the order the parts are needed. Do not simply tear into the boxes and begin removing parts. Contents labels on the box exteriors provide details as to what is in each box. Avoid opening boxes until you need them to reduce the chance of parts being lost or damaged on site.
STEP THREE: Prepare to Install Your Ducting.
It is important for the installer to understand the layout the system designer planned for the ducting. Follow all local codes and regulations and note loading capabilities of structures to ensure the ducting is properly supported and that the building can carry the ducting system.
If your installer doesn’t understand the layout, he likely will not have all the parts necessary to complete the job. If you or your installer do not have a clear understanding or drawing of the system you are about to install, please call the person who designed the system before you begin work.
NOTE: This is a step where you could possibly find that you do not have all the parts necessary to complete the job. In that case, contact your dealer immediately so that he or she can get the needed parts to you as well as help you verify that your layout matches the one planned by the system designer.
STEP FIVE: The Quick-Fit Sleeve.
- Measure the distance you want to span.
- Cut the pipe (NOT the 11" Quick-Fit Sleeve) approximately 4" shorter than the length necessary to complete the span. Make sure the cut is free of burs and that it maintains its round shape.
- Slide the cut end of the QF Pipe into the Quick-Fit Sleeve (formerly known as the Adjustable Nipple). Clamp one end of the assembly into place. Be sure that the 11" Quick-Fit Sleeve is downstream (closest to the dust collector) of the cut piece.
- Slide the QF Pipe into the Quick-Fit Sleeve to the desired length.
- Slide the O-ring across the rolled edge of the Quick-Fit Sleeve so that it is around the cut piece of QF Pipe. Roll the O-ring until it is seated against the rolled edge of the Quick-Fit Sleeve. The O-ring will form a seal and provide a rolled surface for the QF Clamp to grab when clamped.
- Use a standard QF Clamp to connect the rolled edge of the Quick-Fit Sleeve and the O-ring together.
- Slide the o-ring across the rolled edge of the 11" sleeve so that it is around the cut piece of pipe. Roll it until it is seated against the rolled edge
of the sleeve. The O-ring will form a seal and provide a rolled surface for the QF Clamp to grab. - Use a standard clamp to connect the rolled edge of the Quick-Fit Sleeve and the O-ring together.
Once in place, you can re-adjust the length of the assembly by releasing the QF Clamp and changing the length of the duct that is inserted into the Quick-Fit Sleeve.
IMPORTANT SAFETY NOTE: To ensure a strong, safe and stable system, there must always be at least four inches of duct inserted into the Quick-Fit Sleeve.

STEP SIX: Supporting Your Ductwork.
Nordfab has a variety of duct hanging devices, but it is your responsibility to ensure the safety of all ducting. Please check with local agencies to ensure that your ducting is supported in a way that meets local codes. When determining the weight your ceiling and hangers must support, always allow for the ducting being 100 percent clogged with whatever material is being conveyed.
STEP SEVEN: Pre-Stretch Your Clamps.
Nordfab QF Clamps are designed to provide a tight seal, which means that they also require some pressure to close. By pre-stretching the clamp around the rolled edge of a single piece of duct, you can make it much easier to close when you connect two pieces together.
IMPORTANT SAFETY NOTE: The ducting must be properly supported.
IMPORTANT SAFETY NOTE: On very rare occasions, unpinned clamps can spring open unexpectedly which can cause the ductwork to drop. Additionally, the handles on unpinned clamps have been known to cause injury when they sprung open.
