SHEET METAL DUCT WORK, SHEET METAL DUCT PARTS - INSTALLATION TIPS

ESTABLISH A STAGING AREA where all sheet metal duct parts can be laid out in the order of assembly. Each shipment has the part number and a box with the sheet metal duct parts to help you locate all ducting parts. It is recommended that you stage the drops separately and as close to the drop locations as possible. (Any shortages must be reported immediately. Delayed reporting will result in further charges.)

ESTABLISH THE 'LINE' OF TRAVEL. You need to establish a straight line by which to install your various duct work lines. You may use an existing beam or you may want to 'pull' a string as your straight line to ensure that you are staying straight throughout the sheet metal duct work installation. All sheet metal duct work installations can begin at the fan end or at the 'pick-

LOCATE AND INSTALL TEMPORARY HANGERS that will support the duct work during the installation process. Hangers can be added and moved as duct is installed, but hangers will be needed during the installation to support the duct. If using the cable hangers, see the instructions in the catalog/price list. If using a rod attached to saddles, you will want to have the saddles attached to the rod, ready to receive the duct.

IF USING 'K-WICK' CABLE HANGERS then refer to illustration below. Figure A represents the forming of a loop around a beam or other object from which the duct work will be suspended. Figure B and C illustrate the way the cable goes through the free sliding end of the "clutcher' , around the ductwork and back through the hole in the 'clutcher' that contains the gripping bar. A 'thumb tab' (D) on the side allows for release of the cable if needed.

CLAMP TOGETHER STRAIGHT RUNS ON THE FLOOR but limits the lengths to a manageable number of sheet metal duct parts and pieces. Remember: longer sheet metal duct parts are harder to maneuver and require more hangers.

ALWAYS INSTALL CLEVIS PIN IN CLAMP as soon as it is latched. This is especially important during installation so as to avoid accidental unclamping.

FIT TO LENGTH where necessary. The duct is 5' long and of course must be fitted/cut to address shorter needs.
An adjustable sleeve is incorporated in the system and provides for infinite adjustment of lengths 12" to app 5'10". Shorter (1" - 11") incremental adjustments can be achieved using the adjustment capability of the collars on the end of the various fittings.

STEP 1:
For a sleeve - Cut a standard length of pope to a length slightly shorter than what you need to make the connections.
For a fitting - Cut a standard length of pipe slightly longer than the length needed.

STEP 2:
Slide the cut piece of pipe into the fitting and use an O-ring and clamp to secure the fit.

FINAL CONNECTIONS TO MACHINES / DUST PORTS / ETC. is often best accomplished using flex hose. While hard ducting to the port is often preferred, the flex hose provides a great deal of 'forgiveness' in the hook-up. Simply clamp your hose adapter to the end of the duct and a machine adapter to the port. Then slide the flex hose over the end and clamp with a worm clamp.

NOTE:

MIST INSTALLATIONS require that the duct and clamps of horizontal runs be installed with the seams and the clamp handles are on the top of the duct. Adjustable sleeves (usually installed with respect to air flow) must be installed with respect to 'drainage'. For example: In a vertical drop, the sleeve should be at the bottom of the assembly with the cut end of the pipe facing down. Special gasketing in the clamps is also an important consideration. make sure that the clamps are fitted with appropriate material. Heavy applications can be further secured with silicone or other sealants.
