4.7 Galaxy Display Maintenance
A yearly inspection should be completed to maintain safe and dependable sign operation. This
inspection should address the following issues.
If any of the following conditions are noticed, action
must be taken to correct the situation.
· Loose Hardware
Verify fasteners, such as bolts and rivets, have not come loose. Fasteners should be checked and
tightened or replaced as required.
· Excessive Dust Buildup
Occasionally it may be necessary to vacuum the inside of the sign cabinet to remove dust/dirt
buildup that may interfere with airflow.
·
Water Intrusion – Water Stain Marks
Water can enter the sign where weather stripping has come loose or deteriorated or where
fasteners have come loose allowing gaps in the panels or where moisture may be entering around
hardware. Check electronic components for signs of corrosion.
· Corrosion
Check the paint and look for possible corrosion, especially at footings, structural tie points and
ground rods.
4.8 Weather Stripping
To ensure that the sign is waterproof, weather stripping has been provided around the entire sign and
around each module. It is important that the weather stripping is installed properly at all times or water
may leak into the sign and damage the components.
