NOTE:To inquire about the use of the Vector Dynamics Foundation Systemswith homes of four or more sections, other widths, or on homesrequiring pier heights which are not included in these instructions,contact Tie Down Engineering, Inc. at 1-800-241-1806.

IntroductionThese instructions describe the proper use of the lateral and longitudinal foundation system. You may also refer to the home manufacturer’s installation manuals that include the Vector Dynamics system as an alternate foundation system.

GeneralThe Vector Dynamics Foundation System resists lateral & longitudinal wind loads by anchoring the two longitudinalmain rails. The system is approved to be used on single or multi section homes: • Nominally12feetto16feetwide-(singlesection)withmainrailspacingof95inchesorgreateroncenter; multi section main rail spacing of 75 inches or greater on center. • Nominal8footorlesstopplateheightatsidewallswithmainraildepthof12”orless. • Maximumroofslopeof20degrees(4.4”in12”slope). • Additionalsystemsmaybeneededforroofslopesgreaterthan20degrees,4.37”in12”pitch.Seepage4. • Maximumeaveswidth(roofoverhangofsidewall)of12”forZoneI,8”forZoneIIand6”forZoneIII.

TheVectorDynamicsFoundationSystemhasnotbeendesignedforuseonexposure“D”homeswithin1500feetofthecoastline. Additional vertical anchor ties that are unique to a home’s design may be required by the home manufacturer. These locations may include shear walls, marriage line ridge beam support posts, end frame ties and rim plates.

GENERAL INSTALLATION INSTRUCTIONS

Site PreparationIt is necessary that the home site be properly graded and sloped to prevent water and moisture from standing or flowing beneath the home.

Footings and Frost LinesTheVectorDynamicsFoundationSystemwasdesignedtobeplaceddirectlyontopoftheground(orpouredconcrete)after clearing all loose vegetation. In areas with frost heave, use Vector for Poured Concrete and check with local requirements for footer depth.

Foundation/Footing Specification for Vector PadsVector Pads are used in place of conventional foundation pads. Vector pad sizes provide two or three square feet of bearing support. Vector Systems should be spaced as symmetrically as possible along the length of the home. For pier locations in between the Vector Systems, use the normal foundation pads.

Pipe adapter bracket, part #59281 must be used with PVC pipe simultaneously with the Inside Tie Brackets. The pipe adapter bracket is used on top of the pipe and under the Inside Tie Bracket.

Vector Dynamics Systemfor Concrete ApplicationsInstructions (1 of 3)

The Vector system for concrete pads applies to concrete footers, runners and slabs. Minimum sizeof concrete per Vector pier is 24” x 24” x 4” or 18” round (min) x 10” deep. The bottom offooters must be below the frost line or a minimum of 4” below finished grade whichever is greater. Concrete must be cured sufficiently to prevent spalling at anchors and allow proper installation. Refer also to ACI-308 standards.

1. Determine location of pier sets where the Vector systems will be located.2. PlaceoneVectorconcretepad(galv.metal)ontheconcretewherethepierwillbelocated,centered under the I-beam of the home. Place the upturned edge towards the center of the home and directed to the opposite Vector pier. Do the same for the opposite Vector pier.3. Measure the distance between the two Vector system pads at the base where the Vector pad meets theconcrete.Cuttwogroundtreated2x4’sorSchedule40PVCpipe,oradjuststeelcompression member, to this length and place between the piers as shown.4. Placealongu-boltunderthe2x4’sandthroughtheholesoftheVectorpadasshown.5. Place the concrete pier blocks on the Vector pad. Center the blocks under the frame. The upturned edge end of the Vector pads should be up against the inside of the pier blocks.6. Build vector piers but do not wedge at this time.7. Using a concrete drill bit, drill two holes on each side into the concrete using the holes in the Vector padasaguide.Drillthe3/8”diameterholes3inchesdeep.8.
