To ensure that Nordfab Quick-Fit (QF) continues to be the world's fastest ducting system, we would like to provide a few tips to help your installation proceed quickly, smoothly and safely.
Inspect all boxes for visible damage before signing the delivery receipt. Boxes should be secured to a pallet and should not be crushed, torn or otherwise damaged. If damage is found, either refuse the shipment or record the issue on the delivery receipt before signing. Failure to do so may make future claims extremely difficult to pursue.
Nordfab ships most orders Free On Board (FOB), meaning it is your responsibility to ensure that the materials received have not been damaged in transit and that the carrier has delivered all boxes in the shipment.
Before signing for delivery, ensure that all boxes are accounted for. The total number of boxes can be found on the delivery receipt presented by the driver. Record any discrepancies before signing.
Safety note: be aware of the sharp metal staples used to seal shipping boxes.
Do not immediately open boxes and begin removing parts. At least one box in each shipment will contain Nordfab's Packing List. Locate these documents before opening any boxes, as they provide details of the contents of each box.
To minimise the risk of parts being lost or damaged on site, avoid opening boxes until their contents are required. Nordfab packs boxes to optimise shipping efficiency, not in the order in which the parts will be installed.
It is important for the installer to understand the layout planned by the system designer. Follow all local codes and regulations and consider the load-bearing capacity of structures to ensure that the ducting is adequately supported and that the building can safely carry the system.
If you do not have a clear understanding of the system layout or installation drawings, contact the system designer before beginning work.
Begin by laying out the system on the floor beneath its intended installation location. Remember that components that connect together may not be packed in the same box. Completing this step can significantly reduce installation time once work begins.
Note: this is often the stage at which missing components are identified. If any parts are missing, contact your dealer immediately so that replacement components can be supplied and your layout can be verified against the original system design.
Safety note: to ensure a strong, safe and stable system, there must always be at least 100 mm of duct inserted into the Slip Duct.
Watch the video below for more information on installing a Slip Duct.
Check with local authorities to ensure that duct supports comply with local regulations. It is your responsibility to ensure the safe support of all ducting.
When calculating loading requirements for ceilings and hangers, always assume that the ducting could become completely filled with the material being conveyed.
Nordfab QF Clips are designed to provide an airtight seal and therefore require a degree of force to close. Pre-stretching the clip around the rolled edge of a single section of duct can make it considerably easier to close when joining two sections together.
Closing clips at ground level is generally faster and safer than working from scaffolding. Many installers therefore connect two or three sections of ductwork together on the floor before lifting them into position.
Safety note: The ducting must always be properly supported.
It is unsafe to leave multiple sections cantilevered without adequate support. Each additional section places significant stress on clips and hangers, potentially resulting in clip or hanger failure.
After closing each clip, insert one of the supplied cotter pins into the designated hole as shown. This prevents the clip from opening unexpectedly.
Install the cotter pin immediately after closing the clip and exercise caution around any clips that have not yet been secured.Safety note: Although rare, unclipped pins can allow clips to spring open unexpectedly, which may cause duct sections to fall. In addition, clip handles on unsecured clips have been known to cause injury when they spring open unexpectedly.
