WIND ZONE I

All States, Counties, Parishes or Cities not listed above.

US WIND ZONE CHART

Each manufactured home must be designed according to the federal Manufactured Home Construction and Safety Standards at 24 CFR 3280, commonly called the HUD Code.

The HUD Code stipulates, at §3280.305(c)

(1) and §3280.305(c)(2), that the home shall be designed and constructed to conform to one of three wind load zones. The appropri-ate wind zone used in design is dependent on where the home will be initially installed.

Homes designed and constructed to a higher Wind Zone can be installed in a lower Wind Zone (a Wind Zone III home can be installed in a Wind Zone I or II location).

However, a Wind Zone I home cannot be installed in either a Wind Zone II or III area.

SOIL CLASSIFICATION CHARTS

Ground anchors are designed for different soil classifications: longer models for loose soils, shorter models for harder soils. Prior to installing any ground anchor model, the soil must be tested (with a Soil Test Probe) in order to match approved ground anchor model with site soil class.

WARNING: Before ground anchor installation, determine that the anchor locations around home will not be close to any underground electrical cables, water lines or sewer piping. Failure to determine the location of electrical cables may result in serious personal injury.

Soil Test Probe The Soil Test Probe is used to determine the soil conditions below the surface near the anchor’s helix. Using the Soil Test Probe will ensure maximum anchor holding strength by indicating the proper anchor model for each soil condition.

Using the chart provided, a probe reading can be converted to the recommended anchor for every soil condition.

Instructions

1.	Place probe tip into ground where you intend to place the anchor. Using a 15/16” hex socket with a ratchet or
	breaker bar, rotate the probe in a clockwise direction. (An electric drive machine with an adapter head may
	also be used)
2.	Drive (rotate) the torque probe into the soil until reaching a depth equal to the length of the anchor being installed.
3.	To determine the soil classification:
	•	Place wrench adapter onto torque wrench.
	•	Insert hex portion of wrench adapter onto the earth probe.
	•	Support probe shaft with one hand, while rotating probe steadily with the wrench. (Do not exceed 600 in. lbs.)
	•	Read the torque wrench while rotating probe clockwise.
	•	Use the soil classification chart to cross reference probe readings. Color codes match those printed on Tie
		Downs torque probe.
4.	If probe reading does not match the anchor for that depth, rotate probe to next anchor depth and check reading.
	Continue until reading on probe matches anchor length for depth of reading.
5.	To remove probe, use wrench or electric drive machine in reverse (counter clockwise).

Step 2Step 1 Step 3

Skirting/Side Wall

FRAME ANCHOR INSTALLATION

Manual Anchor Installation

1. Dig holes to a depth of 2/3 of the anchor length. Install anchor with rod or length of pipe for leverage.

2. Replace earth in hole after anchor/plate is installed at full depth. Pack dirt with a tamping rod every 6 inches of fill.

3. Testing may be required in loose soil conditions to check that anchor has proper holding power.

IMPORTANT!

Anchor must be installed to full depth. Anchor head must be at ground level or at the top of the stabilizer plate which is fully installed to ground level.

ANCHORS

1.	Position anchor at a slight back angle (10˚) so that when fully installed, the anchor head will be inside any
	skirting or side wall.

2.	Install anchor to +/- 2/3 depth, then install stabilizer vertically, within 3 in. - 4 in. of anchor shaft, parallel to
	wall of home. Fully drive anchor down the anchor head.

3. Attach strap (see proper strap tensioning), and pretension strap to pull anchor rod against the stabilizer plate.

Operating Instructions:

1.	Attach adapter head to shaft of the EDM motor, tighten
	set screw.

2.	It may not be needed but it is highly recommend to
	attach the handle extension. Using the handle
	extension increases stability while reducing muscle
	strength during installation.

3.	Plug in the drive machine.
		•	Electrical cords must be a minimum 12-2 cord
			up to 50’, 10-2 cord over 50’.
		•	Recommended minimum 1500w generator.

4.	The GFI will shut off power when a ground fault is
	detected. The GFI will also shut off power when it
	detects low voltage or improper amps required to drive
	the motor. Many times the problem will be the use of an
	extension cord that is too long or is too light in gage.
		•	Never operate without the factory installed GFI
			(Ground Fault Interrupter) power cord.

CALL BEFORE YOU DIG... DIAL 811

Before installation of any ground anchor, determine that the ground anchors to be installed will not be near any under ground electrical cables, phone lines, water lines, sewer pipes, or gas lines. Failure to do so may result in serious injury or death.

1. Attach adapter head to shaft of the EDM motor, tighten set screw.

2. It may not be needed but it is highly recommend to attach the handle extension. Using the handle extension increases stability while reducing muscle strength during installation.

Electric Drive Machine Cautions and Warnings:

•	Before installation of any ground anchor, determine that the ground anchors to be installed will not be near any
	underground electrical cables, phone lines, water lines, sewer pipes, or gas lines. Failure to do so may result in
	serious injury or death

• The EDM is designed for operation by two people.

• Do not allow the EDM to be wedged against the home or other solid objects, when operating the EDM.

•	Electrical cord must be a minimum of 12-2 wire size w/ground up to 50 ft.. Longer cords should be 10-2 wire size
	with ground.

• Never operate the EDM in wet or rainy conditions.

• Frayed or patched electrical cords should never be used with the EDM.

• Care should be taken to keep electrical cords away from anchors.

•	Never operate drive machine without the GFI power cord. Damage to motor and injury to operator can result from
	by passing the GFI.

5. Place anchor tip in location where anchor is to be buried.

The Electric Drive Machine (EDM) is designed for operation by two people. Hold anchor in place at the desired installation angle.

6. Place anchor head into adapter, line up anchor shaft with EDM shaft. For easier installation place a 1/2” pull pin or a slotted bolt thru the adapter head (Safety Pin Hole) and anchor head. Make sure the pull pin/bolt comes out the other side. This will prevent the EDM from separating from the anchor.

7. Flip forward/reverse switch to forward.

8. Hold the power switch on until anchor reaches proper depth. The power switch is spring loaded.

If you encounter any problems release the switch and the machine will shut off automatically.

CRIMPING SEALS

Part ID: 59175

To lengthen strap in the field, a double crimp seal splice is required. Overlap strap approximately 12 inches and use two crimp seals evenly spaced, with 2 crimps per seal.

One crimp seal is used when strap is attached to a sidewall bracket or a strap connector. If the brack-et does not have a radius edge, a radius clip (short “U” shaped piece of strap) must be placed between the strap and contact point to protect the strap from sharp edges. Verify state requirements for number of crimp seals required.

APPLICATION: HUD Code Manufactured Homes & Modular Homes

1. INTRODUCTION

At the request of Tie Down Engineering, RADCO investigated the possibility of listing ground anchors produced by Tie Down Engineering, for approval of ground anchors in accordance with RADCO’s Listing Requirements for Ground Anchors.

RADCO’s Listing Requirements for Ground Anchors defines the classification and performance requirements of each respective ground anchor model. The requirements are in general accordance with those developed by the MHI Ground Anchor Task Force and adopted by HUD’s MHCC on March 9, 2011 after accepting minor revisions offered by HUD staff.

2. DESCRIPTION

There are three categories of ground anchors that are specified in this listing. The first group is soil ground anchors, which pertain to all anchors designated for soil classes 2, 3, 4, and 5. The second group is concrete (non-soil) ground anchors, which are designed for installation into class 1 conditions. The third group is a set of soil ground anchors which serve as an alternate to the HUD minimum requirements and are listed with a working load which is less than the requirements prescribed by the MHI Ground Anchor Task Force and adopted by HUD’s MHCC on March 9, 2011.

All Tie Down Engineering Ground Anchors are manufactured using steel in conformance with ASTM A-36. The models under this listing vary with respect to shaft diameter, number and location of helixes, length of shaft and stabilizer device. Table 1 shows a complete description of each ground anchor model, as well as a corresponding stabilizer device.

All ground anchors have a minimum working load of 3,150 lbs and a minimum ultimate load of 4,725 lbs, with the exception of the anchors listed in Table 3.

3. INSTALLATION

The Installation of the ground anchors is to be in accordance with the Manufacturer’s Installation Instructions, as well as:

a) The proper soil class. (Tables 1 & 3, and notes)

b) Minimum angle of pull to the horizontal. (Tables 1 - 3)

4. EVIDENCE SUBMITTED

4.1 Testing has been conducted to verify the compliance of

Tie Down Engineering ground anchors to the RADCO Listing Requirements for Ground Anchors.

4.2 The Quality and process control system used in the

manufacture has been submitted to RADCO. An adequate method of traceability is maintained by the manufacturer. A follow-up Quality assurance audit program is maintained by

RADCO.

5. RECOMMENDATIONS

RADCO recommends that Tie Down Engineering ground anchors be accepted for use with HUD code manufactured homes and modular homes provided that:

5.1 Each ground anchor will be marked with a label, a facsimile of which is shown in figure 1. The label for each facility denotes the RADCO name, and Listing #1349.

5.2 All products are produced only at the facility referenced in this listing.

5.3 The quality control procedures are maintained by the

manufacturing facility as submitted.

5.4 The audit system of RADCO is maintained.

5.5 All products are installed per the manufacturers installation instructions and section 3 of this listing.
