proper installation of the parapet band system. However, always be aware of
your surroundings and site conditions that cannot be taken into consideration
when writing this guideline. It is always your responsibility to ensure a safe and
clean workplace environment. if they are different from what was1. Review the onsite construction plans;
supplied withthe parapet band system or if you are missing anycomponents in
the system call Lektron LED Technologies at 1-800-634-4059 immediately.
It is recommended that you start your installationwith a corner, and then
work to the towers or the back of building. This will allow the smaller section
of cut housing to be on the end opposite of the corners. By doing this it will
eliminate two small sections of housing being close to one another.

PROPER MEASURING AND PLACEMENT OF THE LIGHTBAND SEC. 2
1. Determine if your location is typical or high wind zone.
2. Mark mounting bracket locations. Housings will share a bracket.
Set bracket ¼" from the end of the run.
3. Install using a dab of caulk beneath each #12 x 2 screw penetration as shown.

INSTALLING THE CORNERS
INSTALLING ADJUSTMENT BRACKETS
NOTE: Adjustment brackets should be mounted at equal intervals, to the
mounting brackets. The purpose of the adjustment bracket is to keep the light
band vertically straight. As well as provide stability to the light band.
TIP: APPLY ALL BOTTOM BRACKETS FIRST, ALL TOP BRACKETS NEXT AND THEN
SECURE IN THE MIDDLE.
1. Measure and mark locations for the Adjustment Brackets, install ½ of the
Adjustment Bracket. Use two #12 x 2" tek screws, applied through a
dot of caulk.
1. Set corner housing onto 4 mounting brackets
2. Attach corner to brackets with #10 x ¾" tek
screws.
3. Install the rst 8' aluminum xture housing by aligning to the edge of the
mounting bracket and approximately ¼" from the end of the run. Insure that
housing is plumb and level, shim if required. Fasten each with 5 #10x ¾" Hex
Head tek screws, spaced approximately 2in. apart, through the mounting
bracket.
4. Using four #10 x ¾" tek screws, screw through housing and the xture
coupling while holding the seam together, put one screw into each xture,
joining the pieces together securely.
5. Apply second bracket to the backside of the housing xture using a dot of
caulk for each screw to waterproof. Secure with two #10 x ¾" tek screws.
6. Slide brackets until the housing is plumb. Clamp the adjustment bracket
together and run two #10 x ¾" tek screws through the assembly to
hold securely.
7. Repeat the process.

INSTALLATION OF CUT SECTION & SIZING THE LED SEC. 3
VERY IMPORTANT:
6. Connect 3" boards with wire nutswhen less than one foot is
needed to ll housing with lights. Do not connect more than three
of the 3" LED light boards together.
7. Snap LEDs into the Track.
8. Shortened Track is now
ready for installation.
Insulate or remove unused wires at end of
run to prevent shorting. Do not connect
wires together or to next circuit.
END OF A RUN
DO NOT CUT 1 FOOT LED CIRCUIT BOARDS!
LEAVE NO GAPS BETWEEN BOARDS!
1. Install LED chains into pre-installed clips. Be careful not to break the LEDs.
2. After housing cuts are made and installed, LED light boards must t the size
of the newly cut housing.
3. Install full 1 foot boards until less than 1 foot of space remains.
4. Gently adjust LED lights to t the adjusted housing.
5. Trim LED light board length at wire connections only
Leave the longest wire length possible.
Angle LED Board,
Push into groove and
snap-in, opposite side.
1. Measure and eld cut last section.
2. If this run dead ends into a wall or tower, allow ¼" space to insert an end cap
at the end of the run.
3. Add a coupling to the cut section using #8 screws
4. Additional adjustment brackets are needed for support.

5.Insert low voltage wire into the conduit and
connect to LED.

TESTING EACH SECTION SEC. 5
IMPORTANT: DO NOT SKIP THIS STEP. ALWAYS CHECK ALL LED LIGHTS BEFORE CONTINUING.
DO NOT APPLY 120V TO THE BLUE OR YELLOW WIRES OR DIRECTLY TO THE LED LIGHT BOARDS
REMEMBER: BLACK AND WHITE WIRES ARE FOR 120v POWER IN
YELLOW AND BLUE ARE FOR LOW-VOLTAGE POWER OUT.
1. Using the installed transformers, supply power to the LED light chains by connecting
a temporary 120v connection to the black and white wires on the transformer to power
the LED lights.
2. Check to see if all LEDs are lit and working correctly.
3. If a board or section does not light up, is damaged, etc., disconnect power and check
connections or replace a board by splicing in another.

Polycar bonate Lens Trim Length (Inches)
for a Given Temperature and Length
LENS TRIM GUIDE
LENS INSTALLATION SEC. 6
LENS SIZING, CUTTING, AND INSTALLATION
The lens has a high expansion and contraction rate and therefore must
be trimmed from the overall dimension in accordance with the lens trim
guide.
There is also a UV protection applied to one side of the lens, make
sure that the UV protected side is facing out when installed.
1. First measure each section of housing from end to end, corner to
corner, etc. this will determine your overall length of lens for each
section.
2. reference the “Lens Trim Guide” to theCheck outside temperature,
right to determine the amount of lens that needs to be subtracted from
the overall length.
Note: The length of lens that will be deducted from your overall
length is critical in order to accommodate the expansion and
contraction of the lens in varying temperatures.
3. After determining the Trim Length, subtract that from your overall
length for that section.
Example: 45’ section will require a trim length of 1 3/4”, leaving you
with an overall cut length of 44’ 10 1/4”.
4. Using the example above, cut your lens to 44’ 10 1/4” long using
a sawzall or jig saw.
Use caution when cutting your lens as the vibration caused by
cutting can scratch the lens if not properly secured.
5. Once ready to install the lens, remove the protective lm from both
sides and slide the lens into the bottom portion of the housing see g 1.
Note: This may take two or more
people depending on the length
of the lens.
6. Lift the top of the housing slightly,
and snap lens into the top guide.
Work in the lens from one end to
the other. See g 2.

END CAP INSTALLATION SEC. 7
1. Fasten the silver end cap to the top of the housing using (2) #8 x ½”
silver self-tapping screws.
2. Fasten the bottom of the end cap to the back of the housing using (2)
#8 x ½” silver self-tappingscrews.
3. Slide the upper portion of the red corner cap into the housing and
secure between the lens and the lens ashing.
SILVER END CAP INSTALLATION
1. Place top edge of end cap inside housing lip.
2. Attach bottom trim to hold in place.
