TIE DOWN ENGINEERING VECTOR DYNAMICS INSTALLATION DESIGN INSTRUCTIONS Introduction These 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.
GENERAL INSTALLATION INSTRUCTIONS SITE PREPARATION It 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 LINES The Vector Dynamics Foundation System was designed to be placed directly on top of the ground (or poured concrete) after clearing all loose vegetation. In areas with frost heave, use Vector for Poured Concrete (see pages 16 & 17) to comply with local requirements for footer depth.

Longitudinal Stabilizer Devices As an alternate to installing longitudinal anchors and stabilizer plates, the installer may use longitudinal stabilizing devices, including Tie Down's LSD (Longitudinal Stabilization Device). The use of LSD systems on a single or multi section home replaces longitudinal anchors, stabilizer plates and straps. LSD Combine Vector Dynamics & LSD 2 3 4 1 1. Longitudinal Foundation Pad 2.

Figure 1 50 in. max. Maximum Pier Height Vector Dynamics Foundation Systems may be used on single section homes in Wind Zone I which require pier heights (from surface of Vector pads to top of concrete or metal pier) not to exceed 50 inches under one or both main rail(s). Note that a ground anchor must be used at each Vector system location where the pier height exceeds 24 inches for single section homes.

Vector Dynamics Metal Pier & V-Drive Installation METAL PIER FOUNDATIONS For metal piers, place the piers in the center of the Vector pads. Set the single 4x4 or two 2x4’s through the piers, and bumps against the outside tension brackets. Inside tie brackets mount “upside down” as shown in drawing. Metal piers using the Vector System can only be used on level ground sets. Conventional pier adjusters must be placed under beam with upturned edge directed towards the outside of the home.
VECTOR DYNAMICS INSTALLATION DESIGN INSTRUCTIONS Vector Dynamic Foundation Systems may be used only on homes set on soils classified as Class 2, 3, 4A and 4B as described in the table below: SOIL CLASSIFICATIONS Soil Class Types of Soils 1 Sound hard rock...... Blow Count (ASTM D2586) NA Soil Test Probe (1) Torque Value (2) NA Very dense and/or cemented sands, coarse gravel and cobbles, preloaded silts, clays, and coral’s 40-up More than 550 lbs - in. 2 24-39 350-549 lbs - in.
Vector Dynamics System for Concrete Applications Instructions These instructions are an addendum to the standard Vector Dynamics instructions. Read and follow all applicable instructions and guidelines in the Vector instructions and home installation manual. The Vector system for concrete pads applies to concrete footers, runners and slabs. Minimum size of concrete per Vector pier is 24” x 24” x 4” or 18” round (min) x 10” deep.
Vector Dynamics System for Concrete Applications Instructions 9. 10. 11. 12. 13. 14. 15. 16. 17. Put a washer and nut on one of the 3/8” x 3-3/4” wedge anchors. The nut should be screwed on enough to have 1 or 2 threads showing on the top of the bolt. Place the wedge end of the bolt into one of the holes, going through the outside tension bracket, metal Vector pad and into the concrete. Using a hammer, tap the wedge bolt into the hole. Maximum height for expansion bolt above concrete is 2”.
Asphalt Installation These Asphalt instructions are an addendum to the standard Vector Dynamics concrete instructions. Read and follow all applicable guidelines in the instructions for Vector, the home, office, classroom or portable building being installed. Minimum depth of asphalt is 2 inches with a suitable base material compacted under the asphalt. This system is designed for portable classrooms, offices or other structures using I-beam frames.
