display reaches 85


4.7 Weather Stripping
To ensure that the display is waterproof, weather stripping has been provided around the entire display
and around each module. It is important that the weather stripping is installed properly at all times or
water may leak into the display and damage the components.
4.8 Display Maintenance
A yearly inspection should be completed to maintain safe and dependable display operation. This
inspection should address the following issues.

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 display cabinet to remove
dust/dirt buildup that may interfere with airflow.

Water Intrusion – Water Stain Marks
Water can enter the display 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. Be sure to check around the lift eyes and bolts to ensure that water has not
entered there. If so, replace hardware immediately to prevent more water from entering the
display. Also, check electronic components for possible corrosion.

Corrosion
Check the paint, and look for possible corrosion especially at footings, structural tie points
and ground rods.
If any of the above conditions are noticed, action must be taken to correct the situation.
