17 PulsePak Prime GDED-IOM-216-B9.2.2 Flanged jointsFlanged joints exist where housing modules must be bolted together andwhere accessories are bolted to the outer faces of the housing. In all cases, AAF willprovide sufficient tubes of sealant which must be applied to one of the opposingfaces just prior to the faces being brought together. When applying sealant becareful to circle each bolt hole with the sealant. See also 9.2.4.9.2.3 Products shipped as a single assemblyAll units will be shipped upright with shipping legs installed. Careful lifting,using the supplied lifting lugs, is required to lift the unit prior to lowering the unitonto the pre-prepared foundation.9.2.4 Products shipped in multiple modular assembliesWhere product is shipped with the main housings in multiple modularassemblies, with the legs separate, proceed as follows:Follow item 9.2.4.1 to pre-install the legs and then bring in the housingmodules, in turn bolting the first to its legs before bringing in the second.Pre-apply the sealant to the flanges as 9.2.2 and then bolt the housingstogether.Install all the supplied bolts between housings loosely at first. Access to thebolt holes is gained via the porthole covers and the inlet/outlet openings (removethe covers). When all the bolts are loosely in position they must be tightened in asequence working from the center bolts towards the corners, radiating outwards inopposite side in sequence so that the four corner bolts are last to be tightened. Thispulls the modules together with all the mating flanges flat against each other withno bulges.9.2.4.1 Leg structureAssemble the leg structure onto the prepared foundations or steelwork usingthe supplied GA drawing which shows the position of all the legs and cross braces.Ensure all the nuts and bolts are tightened and the structure is mechanically soundand secure, and level before proceeding to the next stage.Anchors must comply with local code requirements and must be capable ofsupporting dead, live, wind, seismic, and other applicable loads for the area the dustcollector is going to be installed.
