 Change Slide

2. Introduction
This module instructs you on the proper DIRECTV ODU mounting procedures

3. Objectives Upon completion of this module you should be able to:
Select stable mounting surfaces
Mount the ODU to:
Wood walls
Brick or masonry walls
Roof with asphalt shingles
Poles
Non-pens
Level the mast

4. Service Calls and Mounting
On average, only 64% of the DIRECTV mounting installations are correct
There are over $500,000 in customer damage claims each year from improper installations
Take a moment and consider… If you were a customer and within days after installation you had problems would you be upset?

5. The Mount
Think of the mounting of the ODU as the heart beat of the system
Lack of signal renders the system useless

6. Acceptable Mounting Surfaces
Wall
Concrete
Brick
Cinder block
Roof
Pole
Non-pen

7. Other Mounting Surfaces
Stucco
Stucco is a surface that can be easily damaged unless proper steps are followed
Chimney
A chimney is a structure that can be easily damaged unless proper steps are followed
The KaKu Clamp mount, S-Tube mount and Pole mount are suggested alternatives to direct stucco mounting.

8. The Customer’s Role in Mounting
Before starting any work, review the proposed mounting location with the customer
Be cautious of any roof overhangs that may block signal

New Slide

16. Step 1: Proper Mounting Location
Find the best mounting location for the ODU that provides no obstructions to a clear line-of-sight

17. Step 2: Locate the Center Stud
Locate the center of the stud using either of the following methods:
Stud-finder
Locate nail heads

18. Stud-finder Calibrate the stud-finder
DO NOT rock or lift the scanner from the scanning surface, or start moving the scanner before it has calibrated

19. Stud-finder
After the scanner is set securely on the surface and it has been calibrated, slide it horizontally without lifting or rocking it.

20. Stud-finder
To scan for metal place the scanner against the surface and begin to slide the scanner either horizontally or vertically

21. Stud-finder
Once you’ve found an edge, mark the wall with a pencil along the “stud edge grooves” on the scanner

22. Between the two lines is the center of the stud
Stud-finder
Move the stud-finder in the opposite direction to mark the other edge of the stud
Between the two lines is the center of the stud

23. Stud-finder
Now you have located the center of the stud

24. Stud-finder
While working near electrical wiring, use your personal observations and critical thinking skills!
Don’t just let the scanner do the work!

25. Nail Head Location Studs are on 16” centers
Nail heads can be used to locate the center of the stud

26. Nail Head Location
In this picture you can see the nail head under the paint
The installer marked below the nail head

27. Wall Mounting Wall Mounting: Wood Solid, smooth and clean
Lap siding will require a wooden spacer or shim

28. Step 3: Mark the Location
Place foot plate base on surface
Using a pencil, mark the top center hole
Make sure that the mark is in the center of the stud

29. Pull drill bit out frequently to clean wood shavings
Step 4: Pre-Drill
Pre-drilling ensures you hit the wall stud
Just driving a 5/16” lag bolt may split the wall stud
Pull drill bit out frequently to clean wood shavings

30. Drill Bit Selection Use a high quality drill bit
For wood use a wood / metal twist bit

31. Pre-drilling Wood
3” Lag
2 ½”
Drill ½-inch shorter than the lag screw

32. Step 5: Silicone Sealer
Fill the drilled hole with silicone sealer

33. Step 6: Mount the Foot Plate
Place base on surface
Start 5/16” lag bolt in top center pre-drilled hole
5/16” x 3” in top
center hole

34. Step 6: Mount the Foot Plate
3” Lag
Leave the center top lag bolt loose
so the foot plate can be leveled

35. Step 7: Level the Foot Plate
Use a torpedo level to ensure that the foot plate is level and plumb

36. Step 8: Install Remaining Lag Bolts
Mark the remaining 5 holes
Drill a 7/32” pilot in the remaining (5 holes)
Fill remaining 5 holes with silicone
Install 5 remaining 5/16” lag bolts
Tighten and Torque all 6 lag bolts

37. Step 9: Mast Leveling Level the mast
Use the torpedo level or the mast tube bubble level
Tighten the mast bolts down
Mast Tube Bubble Level
