Daktronics Fuelight FL-2109 Series Petroleum Price Displays - Manual (Page 10)

4 Mechanical Installation
Fuelight ™ Petroleum digit displays are designed to operate in ambient temperatures ranging
from -40 o F to +120 o F. However, the overall sign structure should be designed and ventilated
in a way to keep the interior of the sign cabinet at a temperature not to exceed 140 o F.
Items to consider when designing a sign package to house LED price displays include:
• Solar gain from the black face of the price displays
• Solar gain from other sign cabinet surfaces
• Heat gain from electronics inside the displays
• Passive or active airflow with adequate intake and exhaust areas
Daktronics is not responsible for high-temperature failure due to inadequate ventilation.
2.3 Display Mounting
To maintain the structural integrity of the display cabinet, a 90-degree angle between the
cabinet and the lifting method must be maintained.
If damage occurs because of improper lifting procedures, the warranty will be void.
General Mounting Procedure
1. Lift the display into position on the support structure using ALL eyebolts. Refer to
Figure 4 for an example.
Note: Do not attempt to permanently
support the display by the eyebolts.
2. Weld or use 1 /
2
" grade-5 (or
stronger) bolts and hardware to
secure ALL of the clip angles to the
support structure as shown in the
appropriate Shop Drawing.
Note: Clip angles can be substituted
with alternative mounting methods
as long as ALL of the locations are
used.
3. After installation is complete,
carefully inspect the display for any
holes that may allow water to seep
into the display and seal any openings with silicone.
If the eyebolts on the top of the display have been removed, plug the holes with bolts and the
rubber-sealing washer that was removed with the eyebolt unless an overhead structure
protects the area.
