4.6 Thermostats
A thermostat controls when the ventilation fans are turned on in the display. Refer to
for the location of the thermostat. The ventilation fans turn on when the
inside of the display reaches 85
°
F (29
°
C), and turn off at 70
°
F (21
°
C).
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, 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 or replacement 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 immediately to
correct the situation.
