5. INSTALLATION INSTRUCTIONS

DIY DO IT YOURSELF INSTALLATION

If you've decided to take on the challenge of installing your flat-panel television on your own, we've put

together an extensive list of instructions for doing the job right. If this all seems a bit overwhelming, just

give a call to the professionals at Magnolia Home Theater — 1-888-MAGNOLIA (1-888-624-6654).

We'll get the job done quickly, efficiently and correctly. Evening and weekend appointments are now

available!

(Note: This information is provided to help guide your installation. Haier assumes no liability for errors

or the outcome of any installation since each project is unique and tools, materials, techniques, local

codes and regulations vary and change.)Preparing for Your Installation In planning your flat-panel

television install, there are some questions you'll need to ask yourself first. Once these are answered,

you're ready to begin your project: Seating area

Is the system designed around a "sweet spot" or for the same sound and picture everywhere? There

are different products for different designs.

Furniture

You will need room for your equipment — most home theater components require a space

13-15 inches wide by 10-13 inches deep to fit properly.

What kind of seating do you want? Is the room primarily a home theater entertainment area, or

will music be part of what it's used for as well?

Aesthetics

Make sure the equipment you choose doesn't overwhelm the room. Do you have room for a

projection screen, or will you need to find something a little more space effective?

Wire access

Have you planned how you will run wires to your LCD TV locations? Will you have all of your

equipment next to the TV, or will it be hidden in another room or area?

Do you have enough wire to complete the project? Too much wire is better than not enough.

Mounting

Does your TV require a proprietary mounting device? Some manufacturers require specific

mounts for their TVs.

What is the size and weight of your TV? All brackets have weight and size restrictions. It is

necessary to make sure your TV will fit within the limitations of the mount.

Are you going to fit the mount into a tight space or cabinetry? It may be impossible to use some

brackets if the space does not allow the proper leverage.

Will you need to tilt or move the TV from time to time? There are mounts available that will

adjust to the seating arrangement in the room.

Will the TV be positioned at an angle? Special mounts and techniques may be required to keep

your TV mounted at or into an angle.

What will the TV be mounted to? It is necessary to have proper support for your TV. In most cases,

there will be wood, metal or mortar to mount the bracket to.

TV Breakdown - See our TV Selection »LCD TVs: 32" and smaller This type of TV is clean looking and lightweight. They are usually easier to mount and require smaller brackets. LCD TVs: 32" and larger This type of TV is a larger version of their smaller counterparts. They are usually more expensive

in larger sizes than other technologies. Most will work with the same style bracket as plasma TVs.

Plasma TVs: 32" and larger This is the most common type of Flat-Panel TV. These TVs are available in sizes as small as 32" and go all the way past 100". Most have a variety of mounting options. DLP Wall-Mountable TVs This is the least common type of Wall-Mountable TV. There are usually special

requirements for this mount.

Needed Tools. Some tools used in the installation profession can cost hundreds of dollars. However,

these tools can save hours of work on a project and allow a skilled installer to learn about a house's

construction without cutting into the wall. They also eliminate much of the risk involved in working near

electrical and plumbing systems. Here is a list of tools needed for TV mounting:

? Stud finder

? Tape measure

? Level

? Pencil

? Power drill

? Socket wrench

? Allen wrench ? Wall probe — piano wire, etc ? Wire running tools — fish/carpet tape, flex rods, electrical tape

Running Wires You'll need to get a wire from your TV to your equipment. There are a few guidelines

you need to be aware of when it comes to running wires: The National Electrical Code (NEC) is a set of

rules that govern how wires and varying types of power are run in a building. These rules cover both

high voltage (outlets, light switches) and low voltage (phone lines, speaker wires, cable lines). Any work

you do MUST be in accordance with the NEC, as well as local ordinances for your city, county and state.

It's good to have a clear understanding of these rules before you begin. A/V wire can be susceptible to

interference from external sources, such as electrical lines. The NEC dictates minimum safe clearances

for wires, but it is best to keep as much distance between your speaker wires and any potential sources of interference — you don't want to get all the way through your install only to discover your speakers

"buzz" or "hum" constantly. The wire you use is as important as the equipment itself. The type of copper and how thick it is, the jacket protecting the copper, the distance it's run — all of these impact how

your system will perform. Make sure you're choosing wire that is the proper material and has a thick

enough gauge for the location and distance it will be run. There are also different wire ratings that

dictate what kind of wires are run in different areas of a house. For example, certain wires are "in-wall"

rated, while others are rated for what is run outside, underground, in HVAC ducts, etc. Since this is

spelled out by the NEC and in any local restriction codes, it is strongly recommended that you make

use of a professional installer if you're unsure of local ordinances.

Wire Running Techniques Beginner Skill Level — 1 or 2 hours, depending on room

Track molding — This concealment option is an adhesive-backed, hollow, plastic trim that

can hold wiring on the inside. When the wires are run inside the trim, the adhesive sticks it into

place against baseboards, in corners, etc. The trim can also be painted, so it blends better with

the background.

Horizontal channeling — This involves cutting out a path in the wall for the wire to flow

though. Some damage, due to the wall notching or stud drilling, is expected with this technique.

After you run wire though the channel, you will need to patch the hole in the wall.

Intermediate Skill Level — 2 hours, depending on room

Carpet fish — This technique uses a specially designed flat wire to run between the carpet

and the pad. This should usually be routed through low-traffic areas to avoid wear on the wire.

Start by pulling up a section of carpet, usually near where your wire will be run to or from. Then,

feed carpet tape or another suitably long device from the start to the finish of your run and tape

the wire securely.

TECHTIP: When taping wire, make sure to "taper" the wire in a wedge or cone shape

any corners or edges on your tape job can catch and hamper your efforts. This works

—

best with two people

one to feed the wire and one to pull from the other end.

Intermediate Skill Level — 2 hours, depending on room

Wall fish — This technique uses access from a basement or attic to run wires up or down a wall.

Interior walls are usually empty, but exterior walls will often be blocked with insulation.

TECHTIP: If you have access to a wall where you need a wire fished, drill up from the

lower level or down from an upper level into the center of the wall. Once you have an access hole drilled, run your wire fish tool, such as a flex rod, down to where you need the wire run. Tape your wire and feed it through the wall to your desired location.

Attaching the Bracket to the TV/Mount to the Wall Intermediate Skill Level — 3 to 5 hours with little or no experience

Securing Your TV to the Wall

1. Using a partner, lift the TV and use the upper hooked side of the bracket to lock onto the lip of the wall mount. See Photo #32.

Before lowering the TV down, make sure that your wires are

ready for connection. If your TV will not allow connections to be

made when it is flat against the wall, take this time to connect

them while your partner holds the TV in place. 3. Once all the

wires are connected or ready to be connected, gently place the

TV flat against the wall, taking care that no wires get caught or

pinched.4. Take this time to double check that the TV is level. Once this is verified, secure all locking screws or bars.

If you've made it to this point, congratulations on a job well done!

Speaker Breakdown - See our Speaker Selection »Floor standing/Tower Speakers These are the

largest speakers and the most common in dedicated home theater rooms. They consist of a larger

cabinet for the components and have different sized drivers inside. Some towers even come with

amplifiers built into the cabinet. This construction usually allows for the best sound, but they can be

imposing from a price and appearance standpoint. Bookshelf Speakers Quite a bit smaller than their

floor standing cousins, these speakers are designed to provide a happy medium between sound quality

and space efficiency. While bookshelf speakers will lose some of the performance of a larger speaker,

their size makes them a popular choice for many rooms. Satellite SpeakersIn areas where space is at

a premium, satellite speakers are a popular choice. These are small, usually plastic, and are often

included in many cost-effective "home theater in a box" packages. Their small size and cost

effectiveness make them an ideal choice for smaller rooms or a budget system, but their sound quality

often comes up short when compared to higher quality options. Recessed Speakers Some companies

offer a type of speaker that uses the wall or the ceiling as an enclosure. In other words, these

"recessed" speakers put the empty space in those areas to work for you. You will need to consider a

few things for this type of installation:

A suitable mounting depth — Most speakers need 3-6 inches of space behind the wall or

ceiling. If you go this route, make sure there aren't drain lines or wires blocking the way. A sturdy mounting surface — For this, properly installed drywall will usually provide a stable

area. Wire access — Some high quality wire can be as thick as your finger. How do you want it run?

Is the wire you will be using code compliant? (See "Running Wires" section for more

information.) Soundproofing — Things may sound great in one room, but can be irritating to those in the

next room. Proper treatment will cut down unwanted noise, as well as help your sound quality.

A working knowledge of your house's construction — Before you begin installation, know what is

hidden before you cut or drill! This will help avoid any costly uses of the word "oops."

Mounting an On-Wall Speaker Beginner Skill Level — 30 to 60 minutes1. Most on-wall speakers will

have a very straightforward mounting process. If they can be wall mounted, they will have a small hole

on the back or an insert for attaching a mount. Measure where this hole is on the speaker and pick your

desired height.2. When you have located the height for your speaker, use your stud finder to locate a

stud to hang your speaker from.
